Comparing galaxy populations in compact and loose groups of galaxies II: brightest group galaxies
Héctor J. Martínez, Valeria Coenda, Hernán Muriel
The properties of the brightest galaxies (BCGs) are studied in both compact and loose groups of galaxies in order to better understand the physical mechanisms influencing galaxy ev…
An improved method for the identification of galaxy systems: Measuring the gravitational redshift by Dark Matter Haloes
Mariano Javier de León Domínguez Romero, Diego García Lambas, Hernán Muriel
We introduce a new method for the identification of galaxy systems in redshift surveys based on the halo model. This method is a modified version of the K-means identification algo…
Comparing galaxy populations in compact and loose groups of galaxies
Valeria Coenda, Hernan Muriel, Hector J. Martinez
We perform a comparison of the properties of galaxies in compact groups, loose groups and in the field to deepen our understanding of the physical mechanisms acting upon galaxy evo…
Relating bars with the environment in the nearby Universe
Hector J. Martinez, Hernan Muriel
We study the correlation between the fraction of barred spiral galaxies and environmental parameters of galaxies to understand in which environments the bars are more commonly foun…
The Luminosity Profiles of Brightest Cluster Galaxies
C. J. Donzelli, Hernan Muriel, Juan P. Madrid
(Abridged) We have derived detailed R band luminosity profiles and structural parameters for a total of 430 brightest cluster galaxies (BCGs), down to a limiting surface brightness…
The environmental dependence of the red galaxy sequence
Hector J. Martinez, Valeria Coenda, Hernan Muriel
The dependence of the sequence of red galaxies (RS) with the environment is investigated using field, group, and cluster galaxies drawn from the SDSS. Our work focuses in studying…
