Cosmological QUOKKAS: Proof of concept and early results on the Hubble Constant tension Distances are one of the most important yet difficult to get quantities in astronomy. Normally, astronomers use redshifts (which are relatively easy to measure) as distance measure, but this only works if one assumes that there is a relationship between redshift and distance. The relationship between redshift and distance was first observationally verified in the 1920s by Edwin Hubble. He found that the further away a galaxy was, the galaxy... Dr. Jeff Hodgson |

Astronomy for attaining sustainable development goals in Africa Education and its contribution to science, technology, and innovation are the key points for combating poverty in the long term. Education is also a key point for empowering girls and women, which is fundamental for achieving the United Nations Sustainable Development Goals (SDGs).

Distinct pulses captured in the giant magnetic flare from a neutron star In just a tenth of a second, a magnetar -a particularly magnetic type of neutron star- released energy equivalent to that produced by the Sun in 100,000 years. Its study in detail has revealed multiple pulses at the peak of the eruption, which will make it possible to understand these still little-known giant magnetic flares |

Giant planets could reach maturity sooner than expected The Institute of Astrophysics of Andalusia (IAA-CSIC) participates in the study of the giant planets of the V1298 Tau system, which in just twenty million years have already reached their final size. The finding has been possible thanks to radial velocity measurements from the HARPS-N spectrographs, at the Roque de los Muchachos Observatory (ORM), and from CARMENES, at the Calar Alto Observatory (CAHA) |

Unexplored outflows in nearby low luminosity AGNs: the case of NGC 1052 NGC1052 is considered the prototype of AGN-LINERs, an AGN family at low-luminosity for which, so far, the role of outflows in their evolution has been studied the less. Thanks to MUSE and MEGARA IFS-cubes we found that the stars are distributed in a dynamically hot disc whereas the ionised gas is detected mostly in the polar direction up to 3.3 kpc. We found evidences evidence of an ionised gas outflow (jet-powered) propagating in a cocoon of... Dra. Sara Cazzoli |

SO Webloquio: Exploring the transient radio sky with the SKA and its precursors Radio astronomical observations probe particle acceleration in some of the most extreme environments in the Universe. For example, we can trace the relativistic jets produced by accreting black holes; observe flashes from hyper-magnetised neutron stars; and study the aftermath of stars that are ripped to shreds as they pass close to super-massive black holes. These events provide critical information about the extremes of the Universe, but they... Dr Jason Hessels |

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-...

Discovery of a possible satellite galaxy of M33, a neighbouring Local Group galaxy M33, also known as the Triangle galaxy, is the third largest galaxy in the Local Group, after Andromeda and the Milky Way.

New perspectives on the problem of galaxies without dark matter The discovery of numerous very low surface brightness galaxies in the environment of NGC 1052 provides a crucial clue to the debate about the lack of dark matter in some galaxies of this group. The new data points to the existence of a group of galaxies closer than NGC 1052, to which these anomalous galaxies would belong, and the proximity would solve the problem |

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 |

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 |

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.

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...

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.
