Galaxies in different environments have different properties. In dense environments galaxies are more likely to be red, passive ellipticals than in less dense...
Dynamics of galaxies and globular clusters unraveled with two-dimensional kinematics
Two-dimensional stellar kinematics obtained with the integral-field spectrograph SAURON allow the classification of early-type galaxies into 'slow' and 'fast'...
El IAC participa en el mayor mapa del universo realizado por el telescopio James Webb
El mayor programa de observación del Telescopio Espacial James Webb (JWST) ha hecho públicos sus datos: casi 800.000 galaxias observadas en detalle sin...
Emergence of an Ultrared, Ultramassive Galaxy Cluster Core at z = 4
Recent simulations and observations of massive galaxy cluster evolution predict that the majority of stellar mass buildup happens within cluster members by z =...
Environmental Quenching of Low-surface-brightness Galaxies Near Hosts from Large Magellanic Cloud to Milky Way Mass Scales
Low-surface-brightness galaxies (LSBGs) are excellent probes of quenching and other environmental processes near massive galaxies. We study an extensive sample...
Evidence for a Shallow Evolution in the Volume Densities of Massive Galaxies at z = 4–8 from CEERS
We analyze the evolution of massive (log 10[M ⋆/M ⊙] > 10) galaxies at z ∼ 4–8 selected from JWST Cosmic Evolution Early Release Survey (CEERS). We infer the...
Evidence for secular evolution of disc structural parameters in barred galaxies
I will address the effects of bar-driven secular evolution in discs by comparing their properties in a sample of nearly 700 barred and unbarred massive galaxies...
Evolution of the Mass-Metallicity Relation from Redshift z ≈ 8 to the Local Universe
A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of...
Evolution of the Size–Mass Relation of Star-forming Galaxies Since z = 5.5 Revealed by CEERS
We combine deep imaging data from the CEERS early release JWST survey and Hubble Space Telescope imaging from CANDELS to examine the size–mass relation of star...
