Radio continuum halos in nearby galaxies and the CHANG-ES project About a decade ago, the upgrade from the classic Very Large Array into the EVLA, i.e. the Karl G. Jansky Very Large Array (VLA), made it possible to observe fainter radio continuum emission than ever before. The project Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES, PI: J. Irwin) has allowed us to probe gaseous halos of 35 edge-on galaxies with arcsecond details and faint microJansky/beam sensitivities, and to begin answering... Theresa Wiegert |

The First Detections of X-ray Polarization from Supermassive Black Hole Jets and their Physical Implications X-ray polarization is a crucial probe of the magnetic field structure and emission processes in astrophysical systems. This is particularly true for blazars, active galactic nuclei with powerful jets aligned towards our line of sight. In blazars, X-ray polarimetry allows us to investigate the freshly accelerated particles at the heart of the accelerator. Until now, polarization observations have been limited to the radio-to-optical range,... Dr. Yannis Liodakis |

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 |

Coloquio SO: A holistic approach to exoplanet spectroscopy During the last two decades, multiple observation techniques have enabled the study of exoplanet atmospheres, informing us about their chemical composition, thermal distribution and transport processes. The most successful techniques include low-resolution transit and eclipse spectroscopy, phase curves, and high-resolution Doppler spectroscopy. In all cases, the extraction of the atmospheric signal presents a challenge, being comparable to or... Guiseppe Morello |

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 |

An observational study of massive star forming regions at radio wavelengths In their early stages, massive stars have a profound impact on their hosting cloud as reflected by signposts like shocks, bars and shells of swept material resulting from prominent stellar winds, or photo-ionized (HII) regions produced by energetic irradiance. This activity must be taken into account in the study of the mechanism of formation of either massive stars or nearby lower mass companions affected by such harsh conditions. It is known...

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 |

Fossil groups of galaxies: seeing the future looking at the past The nature of fossil groups of galaxies has been debated for over more than 3 decades. This is in part because of the lack of deep multiwavelength data and also due to the low purity of samples selected using solely magnitude gap criteria. The initial results of a sample of bonafide fossil groups using X-ray/optical observations has clarified many of their characteristics, such as high central metal abundances and concentration measurements....

The many “phases” of small bodies Asteroids, comets, and trans-Neptunian objects are collectively known as small bodies. In a way, they are the debris left by the planetary formation in the Solar system, and as such, they carry a lot of information regarding the processes that shaped it. But, small bodies are by no means stationary objects: not only do they move across the sky, but their brightness also changes due to different mechanisms, from rotational variations due to...

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 |

Turning Trash into Treasure: How OH megamasers are contaminating next-generation HI surveys and what they can tell us about galaxy evolution OH megamasers (OHMs) are rare, luminous masers found in (ultra-)luminous infrared galaxies ([U]LIRGs). The dominant OH masing line at 1667 MHz can spoof the 1420 MHz neutral hydrogen (HI) line in untargeted HI emission line surveys. This ambiguity creates a potential source of “contamination” in HI surveys, particularly for next-generation surveys that will reach groundbreaking sensitivities and redshifts.

Although the stellar content has been extensively studied since Salpeter's first work in 1955, the study of the planetary mass regime is only now becoming feasible. I will present a recent census of the Upper Scorpius and Ophiuchus star- forming region, where we identified between 70 and 170 free- floating planets. This is by far the largest sample of... Dra.

Surprises from MAVEN at Mars: Aurora, meteor showers, and a new water loss paradigm The Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft carries the Imaging Ultraviolet Spectrograph (IUVS) to study the Mars atmosphere and atmospheric escape. After more than two Mars years in orbit, IUVS has gained new insights on key phenomena at Mars including dayglow, nightglow, aurora, meteor showers, clouds, solar-planetary interactions and atmospheric evolution. In this presentation, I will highlight three key results... Dr. Nick Schneider |

SO Coloquio: The Antikythera Mechanism and the Mechanical Universe The Antikythera Mechanism. An astronomical calculator and display device found in a first century BCE shipwreck, it is mechanically more sophisticated than anything known from the subsequent millennium. I want to argue that we should be showing admiration rather than amazement, and that the Mechanism fits rather well into its historic context. But this fit has major implications for the development of humanity’s view of the Universe. Prof. Michael G. Edmunds |

Disks around evolved binaries: do they form second-generation planets? Most of the planets are formed around young stars. But can they also form around dying stars? The origin of the diversity and complexity of the detected exoplanetary systems stems from how they form in protoplanetary disks. These disks are intensively studied around young stars thanks to the high-angular resolution provided by recent instruments (VLT, ALMA). However, similar disks are also found around evolved stars, namely post-AGB binaries,... Dr. Jacques Kluska |

Cosmological QUOKKAS: Proof of concept and early results on the Hubble Constant tension Distances are one of the most important yet difficult to get quantities in astronomy. Normally, astronomers use redshifts (which are relatively easy to measure) as distance measure, but this only works if one assumes that there is a relationship between redshift and distance. The relationship between redshift and distance was first observationally verified in the 1920s by Edwin Hubble. He found that the further away a galaxy was, the galaxy... Dr. Jeff Hodgson |

Unexplored outflows in nearby low luminosity AGNs: the case of NGC 1052 NGC1052 is considered the prototype of AGN-LINERs, an AGN family at low-luminosity for which, so far, the role of outflows in their evolution has been studied the less. Thanks to MUSE and MEGARA IFS-cubes we found that the stars are distributed in a dynamically hot disc whereas the ionised gas is detected mostly in the polar direction up to 3.3 kpc. We found evidences evidence of an ionised gas outflow (jet-powered) propagating in a cocoon of... Dra. Sara Cazzoli |

SO Webloquio: Exploring the transient radio sky with the SKA and its precursors Radio astronomical observations probe particle acceleration in some of the most extreme environments in the Universe. For example, we can trace the relativistic jets produced by accreting black holes; observe flashes from hyper-magnetised neutron stars; and study the aftermath of stars that are ripped to shreds as they pass close to super-massive black holes. These events provide critical information about the extremes of the Universe, but they... Dr Jason Hessels |

SO Webloquio: Active Galactic Nuclei as seen from the 7 X-ray eyes of eROSITA Active Galactic Nuclei (AGN) are not longer considered part of a small and exotic source population but are now widely accepted to play a significant role in the evolution of galaxies through cosmic time. However, even 20 years after the realization of the close link between the galaxies and the active SMBH that they host, the various mechanisms and the interconnection are not fully clear. Two complementary approaches are followed to deepen our... Dra. Mara Salvato |

The RoboPol Program: Optical Polarimetric Monitoring of Blazars Blazars are a subclass of Active Galactic Nuclei with relativistic jets pointing at us. For this reason the highly amplified polarized synchrotron emission from their jets dominates in the optical band. Typically, the electric vector position angle (EVPA) of the optical polarized emission in blazars varies in an erratic way. However, in rare cases the EVPA displays long, smooth and monotonic rotations. Being puzzled by this phenomenon missing a... Dr. Dimitriy Blinov |

Search for MIlli-LEnses (SMILE) to discriminate between dark matter models Projects aimed at characterising dark matter properties make use of very different approaches. One such approach is to look for strong gravitational lens systems. Gravitational lensed images with angular separation on milliarcsecond scales probe gravitational lens systems where the lens is a compact object with mass in the range 10^6-10^9 solar masses, i.e a supermassive compact object (SMCO). This mass range is particularly critical for the... Dra. Carolina Casadio |

The continuous rise of bulges out of galactic disks A tantalizing enigma in extragalactic astronomy concerns the chronology and driving mechanisms of the buildup of the central luminosity excess (bulge) in spiral galaxies like our Milky Way, i.e. in systems referred to as late-type galaxies (LTGs) in the Hubble classification scheme. The standard scenario envisages a two-phase galaxy formation process, with the bulge assembling first in a quick and violent quasi-monolithic episode, with the disk... Dr. Iris Breda |

Unveiling the dynamical stage of galaxy clusters through the intracluster light The intracluster light (ICL) is the most unexplored component of galaxy clusters. It is defined as a low surface brightness, extended emission composed by stars that are bound by the potential of the cluster but do not belong to any galaxy in particular. Simulations predict that minor and major mergers can mainly drive the formation of ICL, specially for z Dra. Yolanda Jimenez-Teja |
