Do galaxies die?: Different views from simulations and observations in the local Universe
(Wiley Blackwell Publishing, Inc, 2021-10)
For years, the extragalactic community has divided galaxies in two distinct populations. One of them, featuring blue colours, is actively forming stars, while the other is made up of 'red-and-dead' objects with negligible ...
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 ...
Properties of galaxies with ring structures
(EDP Sciences, 2021-09)
Aims: We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods: We built a catalog of ringed galaxies from ...
ON THE EXTENDED KNOTTED DISKS OF GALAXIES
(2007-07)
The stellar disks of many spiral galaxies are twice as large as generally thought. We use archival data from the
Galaxy Evolution Explorer mission to quantify the statistical properties of young stellar clusters in the ...
Interactions, mergers and the fundamental mass relations of galaxies
(EDP Sciences, 2006-12)
We present a study of the effects of mergers and interactions on the mass distribution of galactic systems in hierarchical clustering scenarios using the disc-bulge structural parameters and their dynamical properties ...
Field spheroid-dominated galaxies in a Λ-CDM Universe
(EDP Sciences, 2018)
Context. Understanding the formation and evolution of early-type, spheroid-dominated galaxies is an open question within the context of the hierarchical clustering scenario, particularly in low-density environments. Aims. ...
Dissipationless collapse of spherical protogalaxies and the fundamental plane

'Fundamental Plane'-like relations from collisionless stellar dynamics: a comparison of mergers and collapses
