We have built a new model for the lens system SDSS J1004+4112 including the recently measured time delay of the fourth quasar image. This time delay has a...
The small fraction of dark matter in the galaxy NGC1052-DF4 has worried the astronomical community for several years. Now a team of researchers from the...
Still largely unexplored, the diffuse light in clusters of galaxies traces the past and ongoing buildup of these massive structures. Here we present the first...
A central question regarding ultra-diffuse galaxies (UDGs) is whether they are in a separate category from low-surface-brightness (LSB) galaxies, or just their...
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the...
The journal Nature Astronomy publishes today, in its collection of reviews dedicated to dwarf galaxies, a new article written by Giuseppina Battaglia...
The group of Cosmology and Large Scale Structure at the Instituto de Astrofísica de Canarias (IAC) has developed, using the BAM (Bias Assignment Method)...
The gravitational force in the Universe under which it has evolved from a state almost uniform at the Big Bang until now, when matter is concentrated in...
