Abundance ratios and IMF slopes in the dwarf elliptical galaxy NGC 1396 with MUSE
(Oxford Univ Press, 2016)Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (MV = −16.60, Mass ∼4 × 108 M⊙), located in the Fornax cluster, have been performed with the Very Large Telescope/Multi Unit Spectroscopic Explorer spectrograph ... -
Abundance ratios in dwarf elliptical galaxies
(Oxford Univ Press, 2018)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 magnitude range −19.0 < Mr < −16.0. We analyse ... -
Did brightest cluster galaxies experience more than one star formation epoch?
(Cambridge University Press, 2012)We use the full spectrum fitting ability of ULySS, with the Pegase.HR stellar population model to fit the observed spectra of 40 brightest cluster galaxies in order to determine whether a single or a composite stellar ... -
Diversity in the stellar velocity dispersion profiles of a large sample of brightest cluster galaxies z ≤ 0.3
(Oxford Univ Press, 2018)We analyse spatially resolved deep optical spectroscopy of brightestcluster galaxies (BCGs) located in 32 massive clusters with redshifts of 0.05 ≤ z ≤ 0.30 to investigate their velocity dispersion profiles. We compare ... -
Dynamical masses of brightest cluster galaxies. I. Stellar velocity anisotropy and mass-to-light ratios
(Oxford Univ press, 2020)We investigate the stellar and dynamical mass profiles in the centres of 25 brightest cluster galaxies (BCGs) at redshifts of 0.05 ≤ z ≤ 0.30. Our spectroscopy enables us to robustly measure the Gauss–Hermite higher order ... -
Investigating the star formation histories of the brightest cluster galaxies
(Oxford Univ Press, 2014)This article is devoted to the study of the central stellar populations of the brightest cluster galaxies (BCGs). High signal-to-noise ratio, long-slit spectra for a sample of 39 galaxies were fitted against two stellar ... -
The regulation of star formation in cool-core clusters: imprints on the stellar populations of brightest cluster galaxies
(Oxford Univ Press, 2016)A fraction of brightest cluster galaxies (BCGs) show bright emission in the ultraviolet and the blue part of the optical spectrum, which has been interpreted as evidence of recent star formation. Most of these results ... -
Stellar populations in the centres of brightest cluster galaxies
(Oxford Univ Press, 2009)This paper is part of a series devoted to the study of the stellar populations in brightest cluster galaxies (BCGs), aimed at setting constraints on the formation and evolution of these objects. We have obtained high ...
