Abundance ratios in dwarf elliptical galaxies
Ş. Şen, R. F. Peletier, A. Boselli +14
We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magn…
The puzzling interpretation of NIR indices: The case of NaI2.21
B. Röck, A. Vazdekis, F. La Barbera +4
We present a detailed study of the Na I line strength index centered in the -band at , Å (NaI2.21 hereafter) relying on different samples of early-type galaxies. Consiste…
Young LMC clusters: the role of red supergiants and multiple stellar populations in their integrated light and CMDs
Randa S. Asa'd, Alexandre Vazdekis, Miguel Cervino +3
The optical integrated spectra of three LMC young stellar clusters (NGC 1984, NGC 1994 and NGC 2011) exhibit concave continua and prominent molecular bands which deviate significan…
The hELENa project - I. Stellar populations of early-type galaxies linked with local environment and galaxy mass
Agnieszka Sybilska, Thorsten Lisker, Harald Kuntschner +6
We present the first in a series of papers in Te role of nvironment in shaping ow-mass arly-type earby glaxies (hELENa) project. In this paper we combine our samp…
Stellar content of extremely red quiescent galaxies at z>2
M. Lopez-Corredoira, A. Vazdekis, C. M. Gutierrez +1
CONTEXT. A set of 20 extremely red galaxies at 2.5<z<3.8 with photometric features of old passive-evolving galaxies without dust, with stellar masses of ~10^{11} M_sun, have colors…
Two new confirmed massive relic galaxies: red nuggets in the present-day Universe
Anna Ferré-Mateu, Ignacio Trujillo, Ignacio Martín-Navarro +4
We confirm two new local massive relic galaxies, i.e. untouched survivors of the early universe massive population: Mrk1216 and PGC032873. Both show early and peaked formation even…
