The Hubble and James Webb Space Telescopes, with their outstanding depth and spatial resolution, are opening up the possibility of studying the edges of disk galaxies over a significant cosmic time interval. This allows us to study in detail the evolution of galaxy edges over the past 8 Gyr. The edge of galaxies, understood here as the farthest

Interstellar gas offers advantages when quantifying the structure of the resonances in disc galaxies. The gas is concentrated close to the disc mid-plane, making it easier to determine its in-plane velocity components, and it offers sharp emission lines for good velocity resolution. These properties are shared by atomic, molecular, and ionized gas

Context. Deep learning (DL) techniques are a promising approach among the set of methods used in the ever-challenging determination of stellar parameters in M dwarfs. In this context, transfer learning could play an important role in mitigating uncertainties in the results due to the synthetic gap (i.e. difference in feature distributions between

Due to the complexity of scientific instruments, such as spectropolarimeters, managing instrument sequences can be challenging. To address this problem, a Finite-State Machine (FSM) approach has been used to manage solar observation sequences in the GREGOR Infrared Spectrograph (GRIS). FSMs provide a structured and visual representation of control

The evolution of galaxies appears linked to the growth of supermassive black holes (SMBH), as evidenced by empirical scale relations between hosts' large-scale properties and the mass of their central black holes. This co-evolutionary scenario suggests that all galaxies experience nuclear activity — active phases during which the black hole

In a hierarchical, dark matter-dominated Universe, stellar mass functions (SMFs), galaxy merger rates, star formation histories (SFHs), satellite abundances, and intracluster light (ICL), should all be intimately connected observables. However, the systematics affecting observations still prevent universal and uniform measurements of, for example
