The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large low number-density volumes in between named voids. Galaxies in voids have been found to be of a later type, bluer, less massive, and to have a slower evolution than galaxies in denser environments (filaments and walls). However, the effect of

Context. Radio surveys of early-type stars have revealed a number of non-thermal emitters. Most of these have been shown to be binaries, where the collision between the two stellar winds is responsible for the non-thermal emission. Aims: HD 168112 is a non-thermal radio emitter, whose binary nature has only recently been confirmed spectroscopically

Context. Small planets transiting bright nearby stars are essential to our understanding of the formation and evolution of exoplanetary systems. However, few constitute prime targets for atmospheric characterization, and even fewer are part of multiple star systems. Aims: This work aims to validate TOI-4336 A b, a sub-Neptune-sized exoplanet

Context. The TOI-421 planetary system contains two sub-Neptune-type planets (P b ~ 5.2 days, T eq, b ~ 900 K, and P c ~ 16.1 days, T eq,c ~ 650 K) and is a prime target to study the formation and evolution of planets and their atmospheres. The inner planet is especially interesting as the existence of a hydrogen-dominated atmosphere at its orbital

In contrast to our understanding of density field tracers, the modeling of direct statistics pertaining to the cosmic velocity field remains open to significant opportunities for improvement. The lack of accurate modeling for the nonlinear domain of pairwise velocities restricts our capacity to fully exploit the information encoded in this
