The Africa Millimetre Telescope project - extending the EHT The Africa Millimetre Telescope (AMT) project led by the Radboud University and the University of Namibia aims to realise a new telescope on the Gamsberg mountain in Namibia to extend the existing network of telescopes that together form the EventHorizonTelescope (EHT). For the future of the EHT more independent nodes in the network are needed to increase the overal redundancy of the network and to improve the image quality and allow for time-...

Nuevas perspectivas sobre el problema de las galaxias sin materia oscura El hallazgo de numerosas galaxias de muy bajo brillo en el entorno de NGC 1052 aporta un indicio crucial en el debate sobre la carencia de materia oscura en algunas galaxias de este grupo. Los nuevos datos apuntan a la existencia de un grupo de galaxias más próximo que NGC 1052, al que pertenecerían estas galaxias anómalas, y la cercanía resolvería el problema |

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 |
