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....

SO Colloquio: Moving from high to extreme precision in air shower observations: From LOFAR to SKAO Cosmic rays play an interesting role in understanding the most violent objects in the universe. These charged atomic particles reach energies orders of magnitudes higher than achievable in accelerators on Earth, which points towards an origin of the most extreme objects in the universe, with strong magnetic shocks and mass transfer. However, these sources are not firmly identified. Astrophysical interpretations are currently limited by the... Dr. Anna Nelles |

SO colloquio: A conclusive test of the cold dark matter model The ``Lambda cold dark matter'' (LCDM) cosmological model is one of the great achievements in Physics of the past thirty years. Theoretical predictions formulated in the 1980s turned out to agree remarkably well with measurements, performed decades later, of the galaxy distribution and the temperature structure of the cosmic microwave background radiation. Yet, these successes do not inform us directly about the nature of the dark matter. This... Dr. Carlos Frenk |

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...

SO Colloquio: Galactic Center: Radiation from black hole candidates and the dynamics of high velocity stars We summarize recent research results on the radiation mechanism of the Super Massive Black Hole (SMBH) candidate SgrA* and ask the question if there are Intermediate Mass Black Hole (IMBH) candidates in the central stellar cluster. Furthermore we give an update on the most recent high velocity stars in the central arcsecond - that are closest to SgrA*. Here we concentrate on the high velocity star cluster dynamics and on the 4711+ stars with... Prof. Andreas Eckart |

The EnVision mission to Venus: Discovering why our closest neighbour is so different EnVision was selected as ESA’s 5th Medium-class mission in the Agency’s Cosmic Vision plan, targeting a launch in the early 2030s. The mission is a partnership between ESA and NASA. The primary goal is to provide a holistic view of Venus, from its inner core up to its upper atmosphere by a single mission, and will be the first mission of its kind. More specifically, EnVision will characterise Venus’ core and mantle structure, in order to study... Dr. Anne Grete Straume |

SO Colloquio: Studies on the origins of our solar system My goal in this colloquium is to apprehend globally the Solar System by describing a vast sample of small bodies, from Near Earth Asteroids to remote Trans-Neptunian Objects. This goes beyond projects that focused on certain populations only. The core of the talk is theoretical, with emphasis on inner structures and rings. Meanwhile, the stellar occultations by these objects will provide an exploratory route to characterize objects with widely... Dr. Bruno Sicardy |

New developments at the IAA cosmic dust laboratory The interpretation of astronomical observations of comets and asteroids and of extrasolar objects such as protoplanetary and debris disks is crucial for understanding the origin and evolution of planetary systems. Collecting electromagnetic radiation scattered or emitted by dust particles present in these objects with powerful telescopes is often our only way to observe and characterized them. In situ observations are available for a handful of... Dr. Juan Carlos Gómez |

WHIM). Here I will highlight recent results from the LOFAR and ASKAP radio telescopes,which use the effect of Faraday rotation to illuminate the CGM, IGrM, ICM and WHIM gas. In particular, I...

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 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 |

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 |

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.

My recent work introduces an accurate implementation of equilibrium and dynamical tides in the stellar population code binary_c, relying... Dr. Giovanni Mirouh |
