Effects of environment on stellar metallicity profiles of late-type galaxies in the CALIFA survey
(EDP Sciences, 2020-10)
Aims. We explore the effects of environment in the evolution of late-type galaxies by studying the radial profiles of light- and massweighted metallicities of galaxies in two discrete environments: field and groups. Methods. ...
Young stellar populations in type II quasars: timing the onset of star formation and nuclear activity
(OXFORD UNIV PRESS, 2017)
Despite the emerging morphological evidence that luminous quasar-like active galactic nuclei (AGN) are triggered in galaxy mergers, the natures of the triggering mergers and the order of events in the triggering sequence ...
Dissecting galaxy triplets in the Sloan Digital Sky Survey Data Release 10 - I. Stellar populations and emission line analysis
(Wiley Blackwell Publishing, Inc, 2016-04)
We identify isolated galaxy triplets in a volume-limited sample from the Sloan Digital Sky Survey Data Release 10. Our final sample has 80 galaxy systems in the redshift range 0.04 ≤ z ≤ 0.1, brighter than Mr = −20.5 + ...
A cold stellar stream in Pegasus
(2019-01-01)
We report the serendipitous discovery of a stellar stream in the constellation Pegasus in the south Galactic hemisphere. The stellar stream was detected using the SDSS Data Release 14 by means of a matched filter in the ...
