Planetary system found similar to the future of the Solar System after the Sun's death Scientists from the IAA-CSIC are involved in the discovery of a system formed by a white dwarf star and a planet similar to Jupiter. The discovery, published in Nature, shows that planets can survive the death of their star. |

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 |

SO Webloquio: Space Weather in an Era of Innovative Science The newest generation of solar observational data is allowing a pivot toward making connections in the various solar physics domains and facilitating advanced modeling for space weather conditions and impacts. We study important physical couplings in the solar atmospheric layers, as well as connections from the solar corona through the heliosphere. To advance our understanding of how solar activity and variability impact space weather conditions... Dr. Holly Gilbert |

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 |

Identification and characterisation of emission line galaxies with J-PAS The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) is expected to map thousands of square degrees of the northern sky with 56 narrow band filters (spectral resolution of R around 60) in the upcoming years. This resolution allows to study emission line galaxies (ELG) with equivalent widths of a few armstrongs. Meanwhile the Pathfinder J-PAS camera observed 1 deg^2 with the same photometric system than J-PAS, named... Gines Martinez Solaeche |

Due to the interaction among the galaxy members, they are a great laboratory to study the role of the environment in galaxy evolution. J-PAS survey will soon start to scan thousands of square degrees in the sky, and with its large great field of view (4.2 square degrees) and filter system (56 narrowband filters and 4 broadband filters in the optical spectral range) will provide...

Galaxy morphologies in multi-wavelength surveys In this talk I will present novel results obtained by using a combination of broad and narrow band optical photometry, from the J-PAS and S-PLUS surveys, in the determination and study galaxy of galaxies’ morphologies. In particular we used Morfometrika and GALFITM to recover non-parametric and parametric values to characterize galaxies’ shapes, as well as a deep learning method for the S-PLUS survey to classify galaxies into early and late type...

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 |

SO Webloquio: Unveiling the unseen magnetized universe with MeerKAT Galaxy clusters are known to harbour magnetic fields, the nature of which remains unresolved. Intra-cluster magnetic fields can be observed at the density contact discontinuity formed by cool and dense plasma running into hot ambient plasma, and the discontinuity exists near the second brightest galaxy, MRC0600-399, in the merging galaxy cluster Abell 3376 (redshift 0.0461).

Light pollution has increased by at least 49% in the last 25 years The study only includes data from satellites, very limited for the detection of blue light (the most polluting), so that the real increase can amount to 270% globally.

A high-fidelity sky mock of DESI galaxies in the LCDM cosmology By using N-body simulations in which different cosmologies have been assumed and by comparing them with large-scale galaxy surveys, we can constrain cosmological parameters, even ruling out some cosmological models.

Uchuu is an N-body dark matter simulation that has been created by an international team of researchers from Japan, Spain, USA, Argentina, Australia,... Julia Ereza |

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 |
