Confirmation of the standard cosmological model from red massive galaxies ∼ 600 Myr after the Big Bang In their recent study, Labbe ́ et al. used multi-band infrared images captured by the James Webb Space Telescope (JWST) to discover a population of red massive galaxies that formed approximately 600 million years after the Big Bang. The authors reported an extraordinarily large density of these galaxies, with stellar masses exceeding 1e10 solar masses, which, if confirmed, challenges the standard cosmological model as suggested by recent studies...

Off-centre supermassive black holes in bright central galaxies Supermassive black holes (SMBHs) are believed to reside at the centre of massive galaxies such as brightest cluster galaxies (BCGs), the most massive galaxies which can be found in today's Universe. However, as BCGs experienced numerous galaxy mergers throughout their history, the central BH can be significantly kicked from the central region by these dynamical encounters. By combining the Illustris-TNG300 simulations and orbital integration... Dr. Aline Chu |

J-PAS: a survey for tracing the role that star formation and environment play in galaxy evolution The processes that explain the evolution of galaxies from the blue cloud to the red sequence are still under discussion. Internal processes, named as mass-quenching, because they are linked to the galaxy mass or AGN feedback, could be responsible of the rapid quench of the star formation in galaxies. Besides the stellar mass, the evolution of the galaxy populations is also a function of the environment. Unlike the mass quenching, the... Dr. Rosa González Delgado |

Sub-milliarcsecond astronomy with Imaging Atmospheric Cherenkov Telescopes The angular size of a star is a critical factor in determining its basic properties. Together with the distance, it provides the physical diameter of the star which can be used to yield luminosity and mass estimates. Direct measurement of stellar angular diameters is difficult: at interstellar distances stars are generally too small to resolve by any individual imaging telescope. This fundamental limitation can be overcome by several methods... Dr. Tarek Hassan |

SO coloquio: Investigating the impact of quasar feedback on the central kiloparsecs of galaxies Active galactic nuclei (AGN) feedback is the effect that nuclear activity produces in the interstellar and circumgalactic medium of galaxies. Different modes of AGN feedback, which can be broadly divided into radiative/quasar and kinetic/radio, are now considered key processes in the evolution of massive galaxies by regulating black hole and galaxy growth. Indeed, a wealth of observational evidence demonstrates that feedback from supermassive... Dr. Cristina Ramos Almeida |

When accretion is as vital as extreme: from massive young stars to binary black holes Accretion is vital for understanding the properties of a number of astrophysical objects, including massive young stars and black holes. For the former, accretion drives the stellar mass growth and multiplicity through gas fragmentation. It also powers strong outflows that regulate the interstellar medium. For black holes, only accretion allows for electromagnetic detection. Hence, the multi-messenger astronomy, for which the loudest sources of... Dr. Raphael Mignon-Risse |

SO Coloquio: Dirty Dancing: piercing the dusty environment of merging supermassive black holes It is a posit of modern astrophysics that most massive galaxies host a super- massive black hole (millions to billions of times more massive than the Sun). These black holes affect the evolution of galaxies well beyond their gravitational sphere of influence (which does not extend wider than 1/1000th of the typical galaxy linear size). In turn, the evolution of galaxies affects the growth of black holes through, e.g., galaxy merging.... Matteo Guainazzi |

The effect of pre-processing on the stellar population content of early-type dwarf galaxies According to the CDM model, galaxy clusters grow through the accretion of individual galaxies and galaxy groups. Thus, it is a true challenge to distinguish the possible role of the present-day host halo from that of previous ones, in the transformation of accreted galaxies. Dwarf early-type galaxies (dEs) are often regarded as statistically meaningful testbeds for investigating environmental effects mainly due to their high number density and... Dr. Bahar Bidaran |

SO Webloquio: Cold gas constraints via HI Intensity Mapping in the SKA era Intensity mapping surveys of neutral hydrogen (HI) are a new way to measure the large-scale matter distribution of our universe over a wide range of redshifts, and thus constrain cosmological parameters describing the universal expansion. The next generation of radio telescopes and interferometers - in particular the Square Kilometre Array (SKA) - are being designed and built to include optimising the detection of the HI line at low spatial...

SO Web-loquio: Old/new problems with Active Galactic Nuclei and AGN application to cosmology After several decades of studies the basic nature of nuclear activity of galaxies is well understood. However, unexpected behaviour of AGN was already noted in the past, and with rise of the amount of data we see numerous evidences of phenomena which still require explanation, line Quasi-Periodic Ejection sources, and Changing-Look AGN. Also it is now time to address in more detail the physical nature of the simple AGN components like Broad Line... Prof. Bozena Czerny |

Revisiting the intermediate- to high-mass star formation Intermediate and high-mass forming stars have a large impact on the interstellar medium and nearby star forming regions. Historically, the study of the general properties of intermediate- to high-mass pre-main sequence stars has been hampered by the lack of a well-defined, homogeneous sample, and because few and mostly serendipitously discovered sources were known. As a consequence, many open problems involving high-mass star formation suffer... Dr. Miguel Vioque |

SO Colloquium: Sex and gender analysis in research and Innovation This lecture aims to increase researchers’ awareness of the current demands for the inclusion of sex and gender in their research. In fact, several governments and granting agencies, such as the European Commission and the Spanish Agencia Nacional de Investigación (AEI), now require that requests for funding address whether, and in what sense, sex and gender are relevant to the objectives and methodologies of the research proposed. Parallel with... Dr. Capitolina Díaz |

SO Webloquio: Stellar Magnetism and Extra-Solar Space Weather The environment around the Sun and other late-type stars is controlled by magnetic fields. The coronal high-energy radiation (Extreme Ultra-Violet and X-ray photons), the structure and strength of stellar winds, as well as transients such as flares, coronal mass ejections (CMEs), and energetic particle events, are some examples of this magnetic influence. Apart from their direct consequences on the star and its evolution, these phenomena will... Dr. Julián Alvarado-Gómez |

New insight into the magnetism of isolated white dwarfs Many stars evolve into magnetic white dwarfs, but we do not know when the magnetic field appears at their surface, if and how it evolves during the cooling phase, and, above all, what are the mechanisms that generate the field, and why they act on some but not all degenerate stars. Observations may help to find an answer to these questions, but their interpretation is dramatically affected by biases due to target selection and a non-homogeneous... Dr. Stefano Bagnulo |

SO colloquio: A new look at the torus of active galactic nuclei The classical picture to explain the observations of active galactic nuclei (AGN) required a geometrically and optically thick torus of molecular gas and dust to obscure the central engine from some lines of sight. For more than two decades, the torus was believed to be a compact (pc-scale), isolated, and rotating structure. Our recent work in the Galactic Activity, Torus, and Outflow Survey (GATOS), using ALMA and high-angular resolution mid-... Dr. Almudena Alonso Herrero |

SO Webloquio: Dwarf Galaxies and the Smallest Supermassive Black Holes Despite traditional thinking, an appreciable population of (relatively small) supermassive black holes may be lurking in dwarf galaxies. Before the last decade, nearly all known supermassive black holes were in the nuclei of giant galaxies and the existence of such black holes in dwarf galaxies was highly controversial. The field has now been transformed, with a growing community of researchers working on a variety of observational studies... Dr. Amy Reines |

SO webloquio: Star-planet plasma interactions and radio emissions Exoplanets are expected to sustain various plasma interactions with their parent star, depending on the stellar and planetary magnetic field strengths and on the sub- or super-Alfvénic wind speed at the planet’s orbit. Three such interactions lead to electron acceleration and subsequent radio emissions in our solar system: magnetized planets hit by the super-Alfvénic solar wind, and the sub-Alfvénic interactions of the unmagnetized moon Io and...

SO Webloquio: Optical interferometric studies of star and planet formation A first step towards understanding planetary formation is the characterisation of the structure and evolution of protoplanetary discs. Although the large scale disc is understood in some detail, very little is known about the inner few au. In this region, dust grains sublimate, and accretion and ejection take place, affecting the entire disk structure and evolution. In this talk, I will review how optical interferometric observations can... Dr. Rebeca García López |

Radio astronomy in the pre-SKA era: What can Apertif do for you? With the Square Kilometre Array still several years away, SKA pathfinder telescopes are already enabling transformational science in radio astronomy with their astounding improvements in field-of-view, sensitivity, spatial resolution, and spectral bandwidth coverage. The APERture Tile In Focus (Apertif) is one such SKA pathfinder: a phased array feed instrument upgrade to the Westerbork Synthesis Radio Telescope that increases the field-of-view...

Detailed equilibrium and dynamical tides: impact on circularization and synchronization in open clusters Binary stars evolve into chemically-peculiar objects and are a major driver of the Galactic enrichment of heavy elements. During their evolution they undergo interactions, including tides, that circularize their orbits and synchronize stellar spins, impacting both individual systems and stellar populations. My recent work introduces an accurate implementation of equilibrium and dynamical tides in the stellar population code binary_c, relying... Dr. Giovanni Mirouh |

SO Webloquio: Empirical and physical properties of Lyman continuum emitters Lyman continuum emitters are galaxies showing escaping ionizing radiation, which thus contributes to ionizing the intergalactic medium. They may be the dominant source of cosmic reionization. I will present an overview of the observations and modeling of low-z analogs of the sources of cosmic reionisation recently discovered. HST observations, including UV spectroscopy with COS and rest-UV imaging with the WFC3, combined with ground-based... Dr. Daniel Schaerer |

Time domain astronomy with future X-ray satellites Accreting black holes emit in X-rays at the wave-band in which THESEUS will be observing (0.3 keV-20 MeV) due to their extreme physical conditions. The softer energy range is devoted to thermal emission from the accretion disc and the harder is due to the existence of a hard X-ray emitting corona (with undefined geometry so far). The importance of one component versus the other gives rise to the diverse state classification of accreting black... Dr. Maria D. Caballero-Garcia |

A journey into the Perseus cluster of galaxies The central black hole of active galaxies accretes large amounts of matter and powers jets of relativistic particles that can propagate beyond the host galaxy. Radio galaxies are particularly bright at ∼ GHz frequencies, when the accelerated electrons interact with the magnetic field and produce strong synchrotron emission. Such galaxies residing in clusters evolve in a hot, diffuse, X-ray emitting plasma (the intracluster medium, ICM) which is... Dr. Marie-Lou Gendron-Marsolais |

Destroying Planetary Systems Modern astronomy invests a large amount of effort to search and characterise planetary systems around solar-like stars. In particular, at early stages of their formations in proto-planetary disks. However, we barely know much about the capacities of the planets to survive the harsh environments produced by their host stars during their evolution. In this talk, I will describe the effects a planet can produce by helping shape the mass loss of... Dr. Jesús Toala |

Is it possible to simulate time machines in a laboratory? General Relativity is the most succesful theory we have for describing gravitational phenomena. Its range of applicability is vast: from solar system scales to cosmological scales. It is well-known that GR allows the existence of time machines: devices that are able to generate Closed-Timelike-Curves (CTCs). Although these kind of objects are allowed in GR, most researchers believe that they cannot occur on macroscopic scales. However, it is... Gerardo Garcia |

Imaging the supermassive black hole at the galactic center with the EHT We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A*), the Galactic center source associated with a supermassive black hole. These observations were conducted in 2017 using a global interferometric array of eight telescopes operating at a wavelength of λ = 1.3 mm. The EHT data resolve a compact emission region with intrahour variability. A variety of imaging and modeling analyses all support an image that...

SO Coloquio: Stellar clustering connecting the formation and evolution of galaxies to the formation and evolution of us The clustered nature of star formation leaves a long-term imprint on galaxies, stars, and planets. At young ages, stellar clustering subdivides galaxies into individual building blocks undergoing vigorous, feedback-driven life cycles that vary with the galactic environment. These units structure the interstellar medium spatially, dynamically and chemically, and collectively define how galaxies form stars. At old ages, the relics of clustered... Dr. Diederik Kruijssen |

SO Coloquio: The cloud-scale baryon cycle across the nearby galaxy population The cycling of matter in galaxies between molecular clouds, stars and feedback is a major driver of galaxy evolution. However, it remains a major challenge to derive a theory of how galaxies turn their gas into stars and how stellar feedback affects the subsequent star formation on the cloud scale, as a function of the galactic environment. Star formation in galaxies is expected to be highly dependent on the galactic structure and dynamics,... Dr. Mélanie Chevance |

SO Webloquio: Charting the first billion years of our Universe with the Square Kilometre Array The first billion years witnessed the dawn of the first galaxies, eventually culminating in the final phase change of our Universe: the Epoch of Reionization (EoR). Recent observations allowed us limited glimpses into these epochs, improving our understanding of the timing of the EoR. However, we still do not understand the first galaxies and black holes, the vast majority of which are too faint to be seen directly in the foreseeable future.... Dr. Andrei Mesinger |
