The diffuse light that spreads through groups and clusters of galaxies is made of free-floating
stars not bound to any galaxy. This is known as the intracluster light (ICL) and holds …

Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A
significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low …

The IllustrisTNG project is a new suite of cosmological magnetohydrodynamical simulations
of galaxy formation performed with the arepo code and updated models for feedback …

What are the faintest distant galaxies we can see with the Hubble Space Telescope (HST)
now, before the launch of the James Webb Space Telescope? This is the challenge taken …

We identify six ultra-diffuse galaxies (UDGs) outside clusters in three nearby isolated groups
(0.014< z< 0.026) using very deep imaging in three different Sloan Digital Sky Survey filters …

ABSTRACT We use deep Hubble Space Telescope imaging of the Frontier Fields to
accurately measure the galaxy rest-frame ultraviolet luminosity function (UV LF) in the …

The Javalambre Photometric Local Universe Survey (J-PLUS) is an ongoing 12-band
photometric optical survey, observing thousands of square degrees of the Northern …

Galaxy clusters are the endpoints of structure formation and are continuously growing
through the merging and accretion of smaller structures. Numerical simulations predict that a …

We present an analysis of Multi Unit Spectroscopic Explorer (MUSE) observations obtained
on the massive Frontier Fields (FFs) cluster A2744. This new data set covers the entire …

Exploiting the fundamentally achromatic nature of gravitational lensing, we present a lens
model for the massive galaxy cluster SMACS J0723. 3− 7323 (SMACS J0723; z= 0.388) that …
