Exploring the Star Formation History of Elliptical Galaxies: Beyond Simple Stellar Populations with a New Estimator of Line Strengths
Ben Rogers, Ignacio Ferreras, Reynier F. Peletier +1
(Abridged) We study the stellar populations of 14 elliptical galaxies in the Virgo cluster. We propose an alternative approach to the standard side-band method to measure equivalen…
Radio continuum observations of the candidate supermassive black hole in the dwarf elliptical VCC128
Pieter Buyle, Sven De Rijcke, Victor P. Debattista +4
The presence of black holes (BHs) at the centers of dwarf elliptical galaxies (dEs) has been argued both theoretically and observationally. Using archival HST/WFPC2 data, we found…
Spectroscopic Confirmation of Faint Lyman Break Galaxies at Redshifts Four and Five in the Hubble Ultra Deep Field
James E. Rhoads, Sangeeta Malhotra, Norbert Pirzkal +6
We present the faintest spectroscopically confirmed sample of redshift four and five Lyman break galaxies to date. The sample is based on slitless grism spectra of the Hubble Ultra…
Towards a Solution for the Ca II Triplet Puzzle : Results from Dwarf Elliptical Galaxies
Dolf Michielsen, Mina Koleva, Philippe Prugniel +6
We present new estimates of ages and metallicities, based on FORS/VLT optical (4400-5500A) spectroscopy, of 16 dwarf elliptical galaxies (dE's) in the Fornax Cluster and in Souther…
Unveiling dark halos in lensing galaxies
Ignacio Ferreras, Prasenjit Saha, Scott Burles
We present a spatially resolved comparison of the stellar-mass and total-mass surface distributions of nine early-type galaxies. The galaxies are a subset of the Sloan Lens ACS sur…
Decoding the spectra of SDSS early-type galaxies: New indicators of age and recent star formation
Ben Rogers, Ignacio Ferreras, Ofer Lahav +3
(Abridged) We apply Principal Component Analysis (PCA) to a sample of early-type galaxies from the Sloan Digital Sky Survey (SDSS) in order to infer differences in their star forma…
