On the formation mechanisms of compact elliptical galaxies
Anna Ferre-Mateu, Duncan A. Forbes, Aaron J. Romanowsky +2
In order to investigate the formation mechanisms of the rare compact elliptical galaxies (cE) we have compiled a sample of 25 cEs with good SDSS spectra, covering a range of stella…
Young, metal-enriched cores in early-type dwarf galaxies in the Virgo cluster based on colour gradients
Linda Urich, Thorsten Lisker, Joachim Janz +11
Early-type dwarf galaxies are not simply featureless, old objects, but were found to be much more diverse, hosting substructures and a variety of stellar population properties. To…
A population of faint low surface brightness galaxies in the Perseus cluster core
Carolin Wittmann, Thorsten Lisker, Liyualem Ambachew Tilahun +7
We present the detection of 89 low surface brightness (LSB), and thus low stellar density galaxy candidates in the Perseus cluster core, of the kind named "ultra-diffuse galaxies",…
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…
Implications for the origin of dwarf early-type galaxies: a detailed look at the isolated rotating dwarf early-type galaxy CG 611, with ramifications for the Fundamental Plane's (S_K)^2 kinematic scaling and the spin-ellipticity diagram
Alister W. Graham, Joachim Janz, Samantha J. Penny +4
Selected from a sample of nine, isolated, dwarf early-type galaxies (ETGs) having the same range of kinematic properties as dwarf ETGs in clusters, we use CG 611 (LEDA 2108986) to…
Implications for the origin of early-type dwarf galaxies --- the discovery of rotation in isolated, low-mass early-type galaxies
Joachim Janz, Samantha J. Penny, Alister W. Graham +2
We present the discovery of rotation in quenched, low-mass early-type galaxies that are isolated. This finding challenges the claim that (all) rotating dwarf early-type galaxies in…
The SLUGGS Survey: Dark matter fractions at large radii and assembly epochs of early-type galaxies from globular cluster kinematics
Adebusola B. Alabi, Duncan A. Forbes, Aaron J. Romanowsky +7
We use globular cluster kinematics data, primarily from the SLUGGS survey, to measure the dark matter fraction () and the average dark matter density ($\left< ρ_{\rm DM…
