On the accretion of a new group of galaxies onto Virgo: III. The stellar population radial gradients of dEs
Bahar Bidaran, Francesco La Barbera, Anna Pasquali +6
Using MUSE data, we investigate the radial gradients of stellar population properties (namely age, [M/H], and the abundance ratio of elements [/Fe]) for a sample of nine dwa…
On the accretion of a new group of galaxies onto Virgo: II. The effect of pre-processing on the stellar population content of dEs
Bahar Bidaran, Francesco La Barbera, Anna Pasquali +7
Using MUSE spectra, we investigate how pre-processing and accretion onto a galaxy cluster affect the integrated stellar population properties of dwarf early-type galaxies (dEs). We…
On the accretion of a new group of galaxies onto Virgo: I. Internal kinematics of nine in-falling dEs
Bahar Bidaran, Anna Pasquali, Thorsten Lisker +12
Galaxy environment has been shown to play an important role in transforming late-type, star-forming galaxies to quiescent spheroids. This transformation is expected to be more seve…
The hELENa project - II. Abundance distribution trends of early-type galaxies: from dwarfs to giants
Agnieszka Sybilska, Harald Kuntschner, Glenn van de Ven +4
In this second paper of Te role of nvironment in shaping ow-mass arly-type earby glaxies (hELENa) series we study [Mg/Fe] abundance distribution trends of early-t…
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…
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…
Tidally induced bars of galaxies in clusters
Ewa L. Lokas, Ivana Ebrova, Andres del Pino +5
Using N-body simulations we study the formation and evolution of tidally induced bars in disky galaxies in clusters. Our progenitor is a massive, late-type galaxy similar to the Mi…
