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 |

SO Web-Colloquia: Flaring on the Sun at all scales The Sun shows activity across a wide range of size and energy scales. 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. Using EUV/UV spectroscopy different layers of the solar atmosphere can be probed in order to understand the physical processes that occur. The EUV imaging spectrometer onboard the Hinode...

So Web-Colloquia: The star formation process on cloud-scales in nearby galaxies Where do stars form and how is their formation regulated across galactic disks are two critical questions for our understanding of the star formation process. High angular observations of nearby galaxies allow us to sample the star formation process across entire galactic disks reaching now regularly the scales of the star-forming units, namely Giant Molecular Clouds (GMCs) and HII regions. Such data provide new insights on the molecular gas... Dr Eva Schinnerer |

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...

SO Web-Colloquia: Following black hole evolution from z=5: mergers and outflows The growth and evolution of the most massive black holes, and their host galaxies, can be followed from z=7 and even earlier. 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 |

SO Colloquium: TeV Halos and their connection to the Leptonic Cosmic Ray flux measured at the Earth The origin and propagation of cosmic rays (CRs) is one of the most important questions in astroparticle physics nowadays. 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...

Galaxy clusters and their environment Clusters of galaxies are located at the intersection of cosmic filaments. I will first describe how we have found large extensions around clusters, at optical and/or X-ray wavelengths, suggesting that we are indeed detecting the cosmic web around clusters, and I will discuss some galaxy properties in one of these extended filaments. At the cluster scale, I will then describe our searches for substructures in X-rays and show how X-ray... Dr. Florence Durret |

HI mapping of nearby dwarf galaxies with SKA pathfinders: unique capabilities of KAT-7 and MeerKAT Dwarf galaxies are by far the most numerous galaxies in the Local Universe. Their simple structure and proximity provides a unique window to the detailed investigation of various processes necessary for galaxy formation and evolution. One of the most reliable approach for studying the evolution of galaxies is to look at their physical properties using the neutral hydrogen gas (HI). In this talk I will present ongoing work on the HI properties... Dr. Brenda Namumba |

A companion star: possible origin of the complex shapes of planetary nebulae Data from the TESS space telescope show variability in a sample of planetary nebulae, compatible with the presence of a companion star. This binarity could explain the complex morphologies of these objects, which result from the death of low and intermediate mass stars |

Magnetic fields, rotation, and activity in M dwarf stars M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but we are still lacking a consistent picture of the link between the magnetic fields and underlying dynamo mechanisms, rotation, and activity. For instance, models predict that the maximum magnetic flux a star can generate scales with convective energy stored in its envelope, but no accurate measurements existed until recently....

SO Web-loquio: Active Galactic Nuclei: fueling and feedback Dynamical mechanisms are essential to exchange angular momentum in galaxies, drive the gas to the center, and fuel the central super-massive black holes. While at 100pc scale, the gas is sometimes stalled in nuclear rings, recent observations reaching 10pc scale, or 60mas with ALMA, have revealed, within the sphere of influence of the black hole, smoking gun evidence of fueling. Observations of AGN feedback will be described, together with the... Dr. Françoise Combes |
