Optical polarization of radio-quiet active galactic nuclei and its repercussion within the changing-look scenario The core of Active Galactic Nuclei (AGN) remains under the resolution limit of the vast majority of current telescopes. However, polarimetry provide us with information of those unresolved regions, which would be inaccessible in natural light, such as the presence of dust, magnetic fields or scattering regions. This talk will be focused on the optical polarization properties of radio-quiet AGN and its relation with the geometry of the scattering... Dr. Beatriz Agis González |

Unveiling the low surface brightness Universe From the beginning of time, humankind has wondered what lies behind the darkness of the night sky. From the pre-telescope era to the present, our ability to see the lowest surface brightness details in the sky has improved by a factor of one million. In this talk, I describe how our vision of the sky has changed over time and how the recent developments in ultra deep imaging have speed up our capacity to discover new objects and structures in...

SO Webloquio: Multiple stellar populations in globular clusters: Properties, origin, open questions Globular clusters (GCs) are fascinating objects nearly as old as the Universe that provide insight on a large variety of astrophysical and cosmological processes. However, their formation and their early dynamical evolution are far from being understood. In particular, the classical paradigm describing GCs as large systems of coeval stars formed out of chemically homogeneous material has been definitively swept away by recent high-precision...

SO Webloquia: ESO: supporting European leadership in ground-based astronomy ESO is de facto the lead world-wide organisation in building and operating most powerful ground-based astronomical observatories. The success of the organisation relies on the support of its member states and the cooperation with the community, among other key factors. Over 1000 refereed papers are published every year using data from ESO facilities, with an increasingly larger fraction of these data coming from the archive. Among these... Prof. Xavier Barcons |

SO Webloquio: Polarimetry in the planetary sciences The past few decades have been characterized by the rapid development of astronomical polarimetry that has resulted from new polarimetric instrumentation, new techniques and new theories. Such advances have aided the exploitation of polarimetry in areas ranging from solar system bodies to exoplanets and allowed the development of completely new fields of polarimetric exploration such as cometary nuclei, transneptunian objects, protoplanetary and...

SO Web-Colloquia: The Search for Advanced Extraterrestrial Civilisations via Anomalies in Astronomical Survey Data Energy-intensive civilisations are likely to have a significant impact on both their local and extended environments – we already see evidence for this here on Earth. Advanced technical civilisations may reveal themselves to other civilisations by introducing anomalous signals into astronomical data. Artificial radio signals are perhaps the best known example but there are also many other possibilities e.g. excess infra-red emission due to waste... Dr. Mike Garrett |

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...

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.

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.

We’ve never imaged the Sun’s surface from that close. Solar Orbiter will change that In February 10, 2020, Solar Orbiter, the new ESA's Sun-exploring mission built in collaboration with NASA, was successfully launched atop an ULA Atlas 5 rocket from Cape Canaveral in Florida. Equipped with ten instruments, six for remote sensing and four for in-situ measurements of the solar heliospheric conditions, it will get as close as 0.28 astronomical units (or 42 million kilometres) to the Sun in a mission that can last more than ten...

The power of low activity black holes It is possible that most galaxies host a black hole at the centre, most of the time this being in a relatively quiescent state. The so-called low luminosity Active Galactic Nuclei are characteristic of this phase. These objects represent the vast majority of the active galactic nuclei (AGN) population in the near universe, and still the least conforming class with the standard AGN scenario. Their low luminosity is at odds with their often... Dr. Almudena Prieto |

We shall take a journey from the smallest scale events to the largest energy releases in the solar system. The energy release is due to the magnetic fields on the Sun and how they interact.

SO Web-Colloquia: Recent findings on nova explosions Nova events are the result of the interaction of low-mass binary systems. A compact white dwarf (WD) accretes material from an old and cold companion until a thermonuclear runaway takes place on its surface. Such explosive events can be considered the scaled-down siblings of supernova (SN) explosions, but its study has many advantages over SNe, as nova events are more numerous (some systems even exhibit recurrent explosions within decades) and...

The critical events that shape this evolution are major mergers, Eddington or super-Eddington accretion, violent star formation, and powerful outflows. I will present the results of a systematic study of 40 AGN at z~4.8 using Gemini, VLT, Herschel and ALMA. Our recent (2019) ALMA data allow a fresh look at major mergers... Dr. Hagai Netzer |

CRs generated by known sources also serve as background to those putatively generated by more exotic phenomena such as dark matter. Apart from the known electrons of primary origin and positrons of secondary one, pulsars and sources powered by them are one of the main candidates to contribute to the total amount of CR...
