We examine the far-infrared (FIR) properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νL ν, 2500(erg s -1)]...

In the starburst model for active galactic nuclei (AGN), the observed broad emission lines and their variability are generated by compact, strongly radiative...

Mrk 938 is a luminous infrared (IR) galaxy in the local Universe believed to be the remnant of a galaxy merger. It shows a Seyfert 2 nucleus and intense star...

We present a general analytical formalism to calculate accurately several statistics related to underdense regions in the Universe. The statistics are computed...

On 2023 December 12, the star α Orionis will be occulted by asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyse the...

We use spectral energy distribution (SED) fitting to place constraints on the stellar population properties of 29 quiescent ultra-diffuse galaxies (UDGs) across...

We analyse the stellar absorption features in high signal-to-noise ratio (S/N) near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly...

We study the rest-frame optical mass-size relation of bulges and discs from z ̃ 2 to z ̃ 0 for a complete sample of massive galaxies in the CANDELS fields using...

We aim to review the internal structure and dynamics of the Abell 1351 cluster, shown to host a radio halo with a quite irregular shape. Our analysis is based...
