Infrared properties of star forming dwarf galaxies
Dwarf galaxies are the most common galaxies in the Universe. They are systems believed to consist of matter in a near-primordial state, from which giant...
M33 as a galaxy example that connects the evolution of big and dwarf galaxies in the Local Group.
Based on the double exponential behaviour of the gas mass profile and on the O/H gradient, Robles-Valdez, Carigi & Peimbert (2013) built a sucessful chemical...
We present SEDs for single-age, single-metallicity stellar populations (SSPs) covering the full optical spectral range at resolution (FWHM = 2.3Å). These SEDs...
New cluster candidates in dwarf galaxies of the Local Group
V and I images of the nearby dIrr galaxies Sextans A and Sextans B were searched for the clusters. The cadidates were selected, from a sample of non-stellar...
We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4 m telescope at the Kitt Peak...
Dwarf galaxies are a complex population. They comprise objects with young and old stellar populations, slow and fast rotation, as well as single- and multi...
Properties of the dwarf galaxy population in galaxy clusters
Dwarf galaxies, being the most numerous and fragile galaxy population, provide unique clues on both the formation of baryonic systems and the role played by the...
Dwarf spheroidal (dSph) galaxies are the smallest, closest and most abundant galaxies in the Universe and therefore excellent laboratories to study star...
Rotation found in three galaxies satellites of the Milky Way
An international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science...
