Occurrence of LINER galaxies within the galaxy group environment
(Oxford University Press, 2017-05)
We study the properties of a sample of 3967 low-ionization nuclear emission-line region (LINER) galaxies selected from SDSS-DR7, with respect to their proximity to galaxy groups. The host galaxies of LINERs have been ...
Comparing galaxy populations in compact and loose groups of galaxies: II. Brightest group galaxies
(EDP Sciences, 2013-08)
Aims: 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 evolution in different environments. ...
Green valley galaxies as a transition population in different environments
(Wiley Blackwell Publishing, Inc, 2018-02)
We present a comparative analysis of the properties of passive, star-forming and transition (green valley) galaxies in four discrete environments: field, groups, the outskirts and the core of X-ray clusters. We construct ...
New measurements of radial velocities in clusters of galaxies-V
(EDP SCIENCES S A, 2010)
As a part of our galaxy-cluster redshift survey, we present a set of 79 new velocities in the 4 clusters Abell 376, Abell 970, Abell 1356, and Abell 2244, obtained at Haute-Provence observatory. This set now completes our ...
Galaxy distribution and evolution around a sample of 2dF groups
(EDP SCIENCES S A, 2009)
Context. We study galaxy evolution and spatial patterns in the surroundings of a sample of 2dF groups. Aims. Our aim is to find evidence of galaxy evolution and clustering out to 10 times the virial radius of the groups ...
MASS DISTRIBUTION IN HICKSON COMPACT GROUPS OF GALAXIES
(IOP PUBLISHING LTD, 2010)
This study presents the mass distribution for a sample of 18 late-type galaxies in nine Hickson compact groups. We used Ha rotation curves (RCs) from high-resolution two-dimensional velocity fields of Fabry-Perot observations ...
