Chemical Properties of Star-Forming Dwarf Galaxies
Recent studies of the near-infrared (NIR) properties of dwarf irregular galaxies (dIs) and blue compact dwarfs (BCDs) have provided improved estimates for the...
Chemical Signature of Gas-rich disc-disc Mergers at high Redshift
We performed numerical simulations of mergers between gas-rich disc galaxies, which result in the formation of late-type galaxies. Stars formed during the...
We present chemical abundance determinations of two H II regions in the dwarf irregular (dIrr) galaxy Leo A from Gran Telescopio Canarias (GTC) Optical System...
Chemoarchaeological downsizing in a hierarchical universe: impact of a top-heavy IGIMF
We make use of a semi-analytical model of galaxy formation to investigate the origin of the observed correlation between [α/Fe] abundance ratios and stellar...
CHEX-MATE: A non-parametric deep learning technique to deproject and deconvolve galaxy cluster X-ray temperature profiles
Temperature profiles of the hot galaxy cluster intracluster medium (ICM) have a complex non-linear structure that traditional parametric modelling may fail to...
Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution
We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most...
Científicos del IAC logran caracterizar más de 200 nuevos cúmulos de galaxias detectados por el satélite Planck usando los Telescopios de La Palma
Un equipo internacional liderado por el grupo de Cosmología con cúmulos de galaxias del Instituto de Astrofísica de Canarias (IAC), y en el que participan...
We report broad-band imaging observations which reveal a circum-nuclear gas ring in NGC 4151. The ring is delineated by two arc-like features probably resulting...
Circumgalactic gas absorption in extremely metal-poor dwarf dalaxies
Accretion of metal-poor gas via cold accretion flows has been recently proposed as a means to trigger/sustain star formation in extremely metal-poor dwarf...
