The link between the masses and central stellar populations of S0 galaxies
A. G. Bedregal, A. Aragón-Salamanca, M. R. Merrifield +1
Using high signal-to-noise ratio VLT/FORS2 long-slit spectroscopy, we have studied the properties of the central stellar populations and dynamics of a sample of S0 galaxies in the…
The formation of S0 galaxies: evidence from globular clusters
J. M. Barr, A. G. Bedregal, A. Aragon-Salamanca +2
We test the theory that lenticular (S0) galaxies form from spirals whose star formation has been shut down. We use the globular cluster specific frequency S_N, defined as the numbe…
The Formation and Evolution of S0 Galaxies
A. G. Bedregal
This thesis studies the origin of local S0 galaxies and their possible links to other morphological types. To address these issues, two different approaches have been adopted: a de…
Central Stellar Populations of S0 Galaxies in The Fornax Cluster
A. G. Bedregal, A. Aragón-Salamanca, M. R. Merrifield +1
Based on FORS2-VLT long-slit spectroscopy, the analysis of the central absorption line indices of 9 S0 galaxies in the Fornax Cluster is presented. Central indices correlate with c…
The Tully-Fisher relation for S0 galaxies
A. G. Bedregal, A. Aragón-Salamanca, M. R. Merrifield
We present a study of the local B and K-band Tully-Fisher Relation (TFR) between absolute magnitude and maximum circular speed in S0 galaxies. To make this study, we have combined…
Measuring the fading of S0 galaxies using globular clusters
A. Aragon-Salamanca, A. G. Bedregal, M. R. Merrifield
We test the hypothesis that S0 galaxies are the descendants of fading spirals whose star formation has been shut down, by using the properties of their globular cluster (GC) system…
