The stellar distribution in ultra-faint dwarf galaxies suggests deviations from the collisionless cold dark matter paradigm Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. I will present evidence suggesting deviations from the collisionless Cold DM (CDM) paradigm. In the standard cosmological model the dark matter (DM) particles are collisionless and, because of this very nature, they develop halos with the characteristic central cusp known as NFW profile. Real galaxies do not show NFW profiles but, rather, have a DM mass... Dr. Jorge Sánchez Almeida |

Constraining the Meteoroid Flux in the inner solar system The inner solar system is populated by Interplanetary Dust Particles (IDPs) released from cometary trails and collisions between asteroids. Planetary bodies and satellites therefore encounter a cloud of IDPs along their orbits, giving rise to a permanent bombardment on their respective atmospheres or surfaces. Constraining the magnitude of the mass influx of IDPs onto a solar system body is crucial for understanding the effects in their... Dr. Juan Diego Carrillo Sánchez |

Intersexionality, a key work for diversity? Since we are children we have been taught what we are and we learn how to fit into a set of infinite boxes. Each of these boxes defines us and, at the same time, can be used to discriminate against us, in life and at work. Diversity exists and it could be an advantage for our society. As scientists we should understand how to take care of diversity and use it to improve our work and life quality. One of the main problems in the past has been... Dr. Eleonora Fiorellino |

A complex network perspective on Delta Scuti stars We apply horizontal visibility graphs (HVG) to study the complex network behavior for the delta Sct stars’ light curves observed by TESS. The delta Sct stars are pulsating stars with spectral types A0-F5 and intermediate masses between low-mass stars (≤ 1 Msun) and high-mass stars (≥ 2 Msun). They pulsate in low-order pressure modes and have dominant pulsation frequencies in the 5-80 d−1 range. The high amplitude delta Sct stars (called HADS),... Dr. Elham Ziaali |

Dust in protoplanetary disks, (still) that great unknown Planetary systems are a side effect in the formation of a star. Planets are believed to be just simply the last remaining of dusty circumstellar disks which is formed around the protostar at very early stages. Thus, understanding how planets are formed requires to understand how dust evolve in these disks. It is less than ten years that we have the possibility of mapping the dust distribution in protoplanetary disks with great detail with... Carlos Carrasco González |

New possibilities for atmospheric analysis with Monte Carlo In recent years, significant advancements have been made in scientific computing utilizing the Monte Carlo method, particularly at the intersection of two key communities: the heat transfer community and the computer graphics community. The first breakthrough is that the computation time required to solve radiative transfer becomes invariant, whether the ground is described by a single building or thousands of them, whether the 3D clouds are...

All these are a few examples of questions addressed by researchers when designing instruments, which are later constrained by technological capabilities. This... Dr. José Carlos del Toro Iniesta |

Unraveling the Gamma-ray emission in radiogalaxies and their jets Radio-galaxies are a minority among all extragalactic sources detected in gamma-rays, yet they have excellent potential to study particle acceleration and non-thermal emission in AGN jets. In contrast with blazars, which have jets aligned with the line-of-sight, radio-galaxies have a smaller Doppler boosting factors. The implications are important: First, the distance at which they are detectable in gamma-rays is smaller. Second, the thermal... Mireia Nievas Rosillo |

Laboratory Research on the Atmospheric Impact of Spacecraft Re-entry Debris: Perspectives and Future Challenges The rapid growth of space debris, especially in Low Earth Orbit (LEO), poses a rising risk to both space operations and Earth's atmosphere. Debris fragments, even minuscule in size, can cause significant damage due to their high orbital speeds. To mitigate risks, controlled re-entry of debris is common practice, but this introduces a new concern: the increasing mass of human-made materials injected into the atmosphere.

Journey into the Galactic Heart: Illuminating the Enigma of the Nuclear Star Cluster and the Nuclear Stellar Disc. The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters, which sometimes appear together with larger stellar structures known as nuclear stellar discs. Understanding the relation between nuclear star clusters and nuclear stellar discs is challenging due to the large distance towards other galaxies which limits their analysis to integrated light. In this context, the Milky Way’s centre,... Francisco Nogueras Lara |

Outflows from low to high luminous AGNs Outflows are believed to play a major role in the evolution of galaxies and are said to be ubiquitous within the active galactic nuclei (AGN) population.

If we focus on the low luminosity part of the AGN family, in particular in low ionisation nuclear emission-line regions (LINERs), the impact of outflows is still largely... Laura Hermosa Muñoz |

Coloquio SO: Extracting stellar populations and (mainly) emission line information out of S-PLUS photometry We present tests of a new method to simultaneously estimate stellar population and emission line (EL) properties of galaxies out of S-PLUS photometry. The technique uses the AlStar code, updated with an empirical prior which greatly improves its ability to estimate ELs using only the survey's 12 bands. The tests compare the output of (noise-perturbed) synthetic photometry of SDSS galaxies to properties derived from previous (STARLIGHT-based)... Dr. Roberto Cid Fernandes |
