Thanks to their short orbital periods and hot extended atmospheres, hot Jupiters are ideal candidates for atmosphere studies with high- resolution spectroscopy. New stable spectrographs help improve our understanding of the evolution and composition of those types of planets. By analyzing two nights of observations using the ESPRESSO high

In this paper, the redshift evolution of the galactic bar properties, like the bar length, pattern speed, and bar fraction, has been investigated for simulated galaxies at stellar masses of M * > 10 10 M $\odot$ in the cosmological magnetohydrodynamical simulation TNG50. We focus on the redshift evolution of the bar pattern speeds and the fast bar

We analyse the dynamical state of the galaxy clusters Abell 76 and Abell 1307 from the optical point of view, presenting a coherent scenario that responds to the X-ray emissions observed in these structures. Our study is based on 231 and 164 spectroscopic redshifts, for the clusters A76 and A1307, respectively, obtained mostly with the Telescopio

The growing volume of astronomical data produced by telescopic facilities presents significant challenges and extraordinary opportunities for the scientific community. Specifically, the Canary Islands Observatories generate approximately 1 petabyte of raw images annually from nearly thirty telescope installations, both public and private. These

This research explores the surface properties of ten Centaurs through their reflective properties in the 0.6-5.3 μm range obtained using the JWST/NIRSpec spectrograph in the framework of two different programs: the JWST GO-1 large program "Discovering the Surface Composition of the trans-Neptunian Objects, Icy Embryos for Planet Formation" (DiSCo

C-complex asteroids are dark, low-albedo objects, mainly containing carbon components. Their spectra are usually featureless, especially in the visible-near-infrared (VNIR) wavelengths. However, for some taxonomic types, absorption has been found in the near-UV (NUV) range. Laboratory studies have shown similarities to spectra of chondrite
