Following the crumbs: Statistical effects of ram pressure in galaxies
(Wiley Blackwell Publishing, Inc, 2020-02)
We analyse the presence of dust around galaxy group members through the reddening of background quasars. By taking into account quasar colour and their dependence on redshift and angular position, we derive mean quasar ...
The global environment of small galaxy systems
(Oxford University Press, 2020-02)
The main goal of this work is to investigate the influence of environment at different scales on the properties of galaxies in systems with a low number of members. To this end we used a catalogue of small galaxy systems ...
LINER galaxy properties and the local environment
(Oxford University Press, 2018-05)
We analyse the properties of a sample of 5560 low-ionization nuclear emission-line region (LINER) galaxies selected from SDSS-DR12 at lowred shift, for a complete range of local density environments. The host LINER galaxies ...
Satellites and central galaxies in SDSS: The influence of interactions on their properties
(Wiley Blackwell Publishing, Inc, 2021-02)
We use SDSS-DR14 to construct a sample of galaxy systems consisting of a central object and two satellites. We adopt projected distance and radial velocity difference criteria and impose an isolation criterion to avoid ...
Oxygen yields as a constraint on feedback processes in galaxies
(Wiley Blackwell Publishing, Inc, 2019-09)
We study the interplay between several properties determined from optical and a combination of optical/radio measurements, such as the effective oxygen yield (yeff), the star formation efficiency, gas metallicity, depletion ...
