Are compact groups hostile towards faint galaxies?
(EDP Sciences, 2014-12)
Aims: The goal of this work is to understand whether the extreme environment of compact groups (CGs) can affect the distribution and abundance of faint galaxies around them. Methods: We performed an analysis of the faint ...
Environmental dependence of the galaxy stellar mass function in the Dark Energy Survey Science Verification Data
(Oxford Univ Press, 2017-04-01)
Measurements of the galaxy stellar mass function are crucial to understand the formation of galaxies in the Universe. In a hierarchical clustering paradigm, it is plausible that there is a connection between the properties ...
The dynamical state of galaxy groups and their luminosity content
(WILEY-BLACKWELLMALDEN, 2012)
We analyse the dependence of the luminosity function (LF) of galaxies in groups on group dynamical state. We use the Gaussianity of the velocity distribution of galaxy members as a measurement of the dynamical equilibrium ...
Milky Way type galaxies in a LCDM cosmology
(Oxford University Press, 2009-05)
We analyse a sample of 52 000 Milky Way (MW) type galaxies drawn from the publicly available galaxy catalogue of the Millennium Simulation with the aim of studying statistically the differences and similarities of their ...
Taking advantage of photometric galaxy catalogues to determine the halo occupation distribution
(EDP Sciences, 2015-08)
Context. Halo occupation distribution (HOD) is a powerful statistic that allows the study of several aspects of the matter distribution in the Universe, such as evaluating semi-analytic models of galaxy formation or imposing ...
Near-infrared Adaptive Optics Imaging of Infrared Luminous Galaxies
(The American Astronomical Society, 2013-10-01)
We have established a relation between the brightest super star cluster (SSC) magnitude in a galaxy and the host
star formation rate (SFR) for the first time in the near-infrared (NIR). The data come from a statistical ...
Identification and analysis of the young population in the starburst galaxy NGC 253
(Wiley Blackwell Publishing, Inc, 2018-07)
We present a study of the young population in the starburst galaxy NGC 253. In particular, we focused our attention on searching young star groups, obtaining their main properties and studying their hierarchical organization. ...
