The nature of giant clumps in distant galaxies probed by the anatomy of the Cosmic Snake
Antonio Cava, Daniel Schaerer, Johan Richard +4
Giant stellar clumps are ubiquitous in high-redshift galaxies. They are thought to play an important role in the build-up of galactic bulges and as diagnostics of star formation fe…
SHARDS Frontier Fields: Physical properties of a low mass Lyman-alpha emitter at z=5.75
Antonio Hernán-Caballero, Pablo G. Pérez-González, José M. Diego +20
We analyze the properties of a multiply-imaged Lyman-alpha (Lya) emitter at z=5.75 identified through SHARDS Frontier Fields intermediate-band imaging of the Hubble Frontier Fields…
Morphological Segregation in the Surroundings of Cosmic Voids
Elena Ricciardelli, Antonio Cava, Jesus Varela +1
We explore the morphology of galaxies living in the proximity of cosmic voids, using a sample of voids identified in the Sloan Digital Sky Survey Data Release 7. At all stellar mas…
Structural and dynamical modeling of WINGS clusters. I. The distribution of cluster galaxies of different morphological classes within regular and irregular clusters
Antonio Cava, Andrea Biviano, Gary A. Mamon +8
[Abridged] We use the WINGS database to select a sample of 67 nearby galaxy clusters with at least 30 spectroscopic members each. 53 of these clusters do not show evidence of subst…
Extreme magnification of a star at redshift 1.5 by a galaxy-cluster lens
Patrick L. Kelly, Jose M. Diego, Steven Rodney +42
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z=1.49 (dubbed "MACS J…
Insights on star formation histories and physical properties of Herschel-detected galaxies
P. Sklias, D. Schaerer, D. Elbaz +3
We test the impact of using variable star forming histories (SFHs) and the use of the IR luminosity (LIR) as a constrain on the physical parameters of high redshift dusty star-form…
GASP I: Gas stripping phenomena in galaxies with MUSE
Bianca M. Poggianti, Alessia Moretti, Marco Gullieuszik +15
GASP (GAs Stripping Phenomena in galaxies with MUSE) is a new integral-field spectroscopic survey with MUSE at the VLT aiming at studying gas removal processes in galaxies. We pres…
OmegaWINGS: The first complete census of post starburst galaxies in clusters in the local universe
A. Paccagnella, B. Vulcani, B. M. Poggianti +10
Galaxies that abruptly interrupt their star formation in < 1.5 Gyr present recognizable features in their spectra (no emission and Hd in absorption) and are called post starburst (…
On the stellar masses of giant clumps in distant star-forming galaxies
Miroslava Dessauges-Zavadsky, Daniel Schaerer, Antonio Cava +2
We analyse stellar masses of clumps drawn from a compilation of star-forming galaxies at 1.1<z<3.6. Comparing clumps selected in different ways, and in lensed or blank field galaxi…
OmegaWINGS: spectroscopy in the outskirts of local clusters of galaxies
A. Moretti, M. Gullieuszik, B. Poggianti +9
Studies of the properties of low-redshift cluster galaxies suffer, in general, from small spatial coverage of the cluster area. WINGS, the most homogeneous and complete study of ga…
