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 |

Seen the Unseen in Planetary Nebulae with High-dispersion Integral Field Spectroscopic Observations Planetary nebulae (PNe), the short-lived progeny of low- and intermediate-mass stars, may embed structures with varying kinematical, physical and chemical properties that disclose the rich variety of processes occurring during their formation. These structures hide in direct images, projected against the bright nebular emission, but the advent of high-dispersion integral field spectroscopic (HD IFS) observations provide the means to...

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 |

Lighthouse Piercing Through the Storm Clouds in Massive Star Formation Massive stars play crucial roles in determining the physical and chemical evolution of galaxies. They shape their environment from early in their protostellar phase when they blast the surrounding with powerful jets, up until their violent deaths in the form of supernova. However, they form deeply embedded in their parental clouds, making it challenging to directly observe these stars and immediate environments. Notwithstanding, their massive... Dr Ruben Fedriani |

La navegación astronómica y los instrumentos náuticos a través de la historia Al inicio de la época de los grandes descubrimientos y de las exploraciones oceánicas, los navegantes europeos contaban con medios muy poco fiables para emprender una travesía marítima de larga duración (algunas cartas náuticas, una brújula para marcar el rumbo, técnicas rudimentarias para calcular la latitud y, desde finales del siglo XVI, la corredera para calcular la velocidad del barco). A lo largo de los siglos XVI, XVII y XVIII, se produjo... Francisco José González González |

The PUMA project. Mergers and feedback in local ULIRGs resolved by ALMA and MUSE+AO Galaxy mergers and interactions have a key role in the evolution of galaxies, specially at high-z when they were more common than today. Mergers trigger starbursts and AGN activity, which are both regulated by negative feedback processes, as well as can turn spiral galaxies into massive quiescent objects. The local counterparts of these major interactions and mergers are local ULIRGs (L(IR)/Lsun > 1e12) which, thanks to their proximity, allow... Dr. Miguel Pereira Santaella |

X-ray binary accretion states in AGN? Sensing the accretion disc of supermassive black holes with mid-IR nebular lines Accretion states, which are universally observed in stellar-mass black holes in X-ray binaries, are also anticipated in active galactic nuclei (AGN). This is the case at low luminosities, when the jet-corona coupling dominates the energy output in both populations. Previous attempts to extend this framework to a wider AGN population have been extremely challenging due to heavy hydrogen absorption of the accretion disc continuum and starlight...

SO Webloquio: The Milky Way's young substellar population Young clusters and star forming regions are home to a large number of substellar objects with masses below the hydrogen-burning limit at 0.075 MSun. Most of our knowledge about their populations comes from nearby regions (d lower 400 pc), where we find consistent formation rates of 2-5 young brown dwarfs per 10 newborn stars. Brown dwarf theories, on the other hand, predict that high gas or stellar densities, as well as the presence of massive... Dra Koraljka Muzic |

Is the Bremer Deep Field Ionised at z=7? The talk will show that the population of star forming galaxies in the Bremer Deep Field (BDF) has formed two large ionised bubbles. The sources in the BDF have been completed with a set of expected, though not detected, low luminosity sources at z ~ 7. We have estimated the number of ionising photons produced per second by the different star forming galaxies in the BDF and have compared it with the number that would be required to reionise...

SO WebLoquio: Regularly-spaced 8 micron cores as tracers of the earliest stages of star formation in the spiral arms of nearby galaxies Archival Spitzer Space Telescope images of most nearby spiral galaxies show prominent 8 micron emission cores when viewed with an unsharp mask technique. These cores have the IR colors of young star-forming regions, typically a million years old, behind several tens of magnitudes of optical extinction. They are usually invisible in optical images, and yet the sum of their masses divided by their likely age is comparable to the total star... Dr. Bruce Elmegreen |

SO Web-Colloquia: The influence of the star-forming environment on planetary systems Planet formation occurs at the same time as star formation, and so the environments in which stars are born are also the birthplaces of planetary systems. Star forming regions are very dense, meaning that encounters between stars and planetary systems are common. Furthermore, the intense UV radiations fields from intermediate and massive stars can truncate, or destroy protoplanetary discs. In this talk, I will describe the detrimental effects of...

PHANGS-Halpha : A narrow-band survey of nearby star-forming galaxies observed with ALMA This work collects a representative sample of star-forming galaxies as part of a major effort the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) collaboration has been making to build surveys with matched cloud-scale resolutions. Observations resolved at 50–150 pc are necessary to isolate individual Giant Molecular Clouds (GMCs) and HII regions to probe different phases of star formation from cold gas to stellar clusters. In this... Dr. Alessandro Razza |

SO Web-Colloquia: Osiris-Rex: results on a mission to understand planetary systems In September 2016, the NASA OSIRIS-REx spacecraft was successfully launched from Cape Canaveral Air Force Station, in Florida. That was the beginning of an amazing journey to reach near-Earth asteroid Bennu, collect a sample of material from its surface, and bring it back to Earth in 2023. The so-called “Touch-And-Go” maneuver or TAG, took place on October 20, 2020 and the sample collector head has been safely placed into the Sample Return... Dra. Julia de León |

SO Web-Colloquia: Primordial black holes, gravitational waves and dark matter More than twenty years ago, we predicted that massive primordial black holes (PBH) would form via the gravitational collapse of radiation and matter associated with high peaks in the spectrum of curvature fluctuations, and that they could constitute all of the dark matter (DM) today. In 2015, we predicted the clustering and broad mass distribution of PBH, which peaks at several Msun, and whose high-mass tails could be responsible for the seeds... Dr. Juan García-Bellido |

SO Web-Colloquia: On the formation of stellar clusters In this presentation, I will show how the analysis of the spatial distribution of young stars (YSO) and its comparison to the core population can reveal stellar formation episodes in star forming regions, and help us understand the fragmentation process. I will focus in particular on two very different regions: the relatively massive cluster NGC2264 and the Taurus association. Our recent study of the clump and YSO populations in NGC 2264... Dra.

SO Web-Colloquia: Stellar population gradients and kinematics of ETGs as revealed by MaNGA In this talk I will summarise the findings presented in a series of four papers dedicated to the study of early type galaxies (ETGs) with integral field spectroscopy (IFU) from the MaNGA survey. The formation channels and mass assembly of ETGs is still a matter of debate in current galaxy evolution models. The combined analysis of galaxy kinematics and stellar population gradients (age, metallicity, alpha-enhancement, initial mass function -IMF... Dra. Helena Domínguez Sánchez |

El Primate simbólico. Cómo el lenguaje y la cultura nos hicieron humanos Los humanos nos separamos de nuestro pariente más próximo, el chimpancé, hace unos siete millones de años, un tiempo relativamente corto desde el punto de vista de la evolución. Es evidente la continuidad biológica con el chimpancé en numerosos aspectos fisiológicos y conductuales; es igualmente evidente la brecha cognitiva entre ambas especies. En esta charla trataré de hacer un esquema del proceso de hominización basado en los datos... Pablo Rodríguez Palenzuela |

From direct imaging to gravitational waves: tracing the life of gas giant exoplanets In two decades, the field of exoplanet science has undergone nothing short of a revolution. With such a variety of planetary systems detected, the next step in exoplanet research is to characterise the properties of these systems. In this talk I will focus on “life and adventures” of gas giant exoplanets, and present how future space missions such as JWST, ARIEL and LISA will help us understand the nature, formation and evolutionary history of...
