Studying magnetic fields, dynamics, and fundamental physics near a black hole with current and future mm-VLBI instruments The Event Horizon Telescope (EHT) has imaged the black hole shadows of the supermassive black hole at the center of the galaxy M87 (M87*) and at the center of the Milky Way (Sgr A*). Polarimetric imaging of M87* with the EHT enabled significantly stronger inferences on the black hole and accretion parameters than total intensity data alone. Geometric modeling was a central tool for studying the structure of M87* and Sgr A* in total intensity. In... Dr. Freek Roelofs |

Single-photon gig in Betelgeuse’s occultation In the realm of astronomical exploration, cutting-edge technologies are indispensable. Single-Photon Avalanche Diode (SPAD) sensors offer unparalleled precision, enabling the detection of individual photons with remarkable timing resolution. However, the current use of single-pixel SPAD devices poses limitations on spatially-resolved imaging in astronomy. Enter two-dimensional SPAD detectors, revolutionizing observation capabilities and enabling... Dr. Francisco Prada |

Astronomers image for the first time a black hole’s shadow together with a powerful jet The Institute of Astrophysics of Andalusia (IAA-CSIC) participates in obtaining an unprecedented panoramic view, which shows for the first time the black hole and the jet of matter that emerges from it. The data reveals that the black hole in the galaxy M87, the first to be imaged, consumes matter at a very low rate. |

SO colloquio: Theoretical models for the formation and evolution of Ultra-Cool Dwarf planetary systems Rocky planets located in the habitable zones around very low-mass objects are ideal targets for searching for life outside our Solar System. In order to better understand their formation and evolution, N-body simulations are needed. These simulations are developed assuming a star close to the substellar mass limit as the central object. The simulations include tidal and general relativistic effects that incorporate the contraction and evolution... Dr. Mariana Sánchez |

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 |

I review current understanding of how massive stars form in our Galaxy, in particular examining observational tests of various predictions of Core Accretion and Competitive Accretion theories. Finally, I discuss how massive star formation may have been different in the very early universe and how the first stars may have become supermassive... Dr. Jonathan C. Tan |

The impact of the DART mission excavated more than five million kilos of material from the asteroid Dimorphos The Institute of Astrophysics of Andalusia (IAA-CSIC) is participating in the study of the material ejected by the impact, which altered the asteroid's orbit around its companion Didymos and produced a crater. The slower material was pushed in an anti-solar direction (almost opposite to the impact) by solar radiation pressure to form a tail, and the faster material showed complex interactions with the asteroid pair |

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 |

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 |
