Morpho-kinematics of MACS J0416.1-2403 low mass galaxies
B. I. Ciocan, B. L. Ziegler, A. Böhm +2
We use optical spectroscopy from VLT/MUSE, as well as photometric observations from HST and VLT/HAWK-I, to study the morpho-kinematics of 17 low mass MACS J0416.1-2403 cluster gala…
OMEGA -- OSIRIS Mapping of Emission-line Galaxies in A901/2: II. -- Environmental influence on integrated star formation properties and AGN activity
Bruno Rodríguez Del Pino, Alfonso Aragón-Salamanca, Ana L. Chies-Santos +5
We present a study of the star formation and AGN activity for galaxies in the Abell 901/2 multi-cluster system at z~0.167 as part of the OMEGA survey. Using Tuneable Filter data ob…
Galaxy kinematics in the XMMU J2235-2557 cluster field at z~1.4
J. M. Pérez-Martínez, B. Ziegler, M. Verdugo +2
We took spatially resolved slit FORS2 spectra of 19 cluster galaxies at z=1.4, and 8 additional field galaxies at 1<z<1.2 using the ESO Very Large Telescope. The targets were selec…
Disk galaxy scaling relations at intermediate redshifts - I. The Tully-Fisher and velocity-size relations
Asmus Boehm, Bodo L. Ziegler
We took spatially resolved slit spectra of 261 field disk galaxies at redshifts up to z~1 using the FORS instruments of the ESO Very Large Telescope. Our spectroscopy was complemen…
OMEGA -- OSIRIS Mapping of Emission-line Galaxies in A901/2: I.-- Survey description, data analysis, and star formation and AGN activity in the highest density regions
Ana L. Chies-Santos, Bruno Rodríguez del Pino, Alfonso Aragón-Salamanca +8
We present an overview of and first results from the OMEGA survey: the OSIRIS Mapping of Emission-line Galaxies in the multi-cluster system A901/2. The ultimate goal of this projec…
The environmental dependence of the structure of galactic discs in STAGES S0 galaxies: implications for S0 formation
David T. Maltby, Alfonso Aragón-Salamanca, Meghan E. Gray +4
We present an analysis of V-band radial surface brightness μ(r) profiles for S0s in different environments using HST/ACS imaging and data from the Space Telescope A901/2 Galaxy Evo…
Kinematic Evolution of Field and Cluster Spiral Galaxies
Bodo Ziegler, Asmus Boehm
We investigate the evolution of the Tully-Fisher relation out to z=1 with 137 emission-line galaxies in the field that display a regular rotation curve. They follow a linear trend…
OMEGA: OSIRIS Mapping of Emission-Line Galaxies in A901/2
Bruno Rodriguez Del Pino, Ana L. Chies-Santos, Alfonso Aragon-Salamanca +2
This work presents the first results from an ESO Large Programme carried out using the OSIRIS instrument on the 10m GTC telescope (La Palma). We have observed a large sample of gal…
Abell 2384: the galaxy population of a cluster post-merger
Florian Pranger, Asmus Böhm, Chiara Ferrari +4
We combine multi-object spectroscopy from the 2dF and EFOSC2 spectrographs with optical imaging of the inner 30'x30' of A2384 taken with the ESO Wide Field Imager. We carry out a k…
The galaxy population of the complex cluster system Abell 3921
Florian Pranger, Asmus Böhm, Chiara Ferrari +6
We present a spectrophotometric analysis of the galaxy pop. in the area of the merging cluster Abell 3921 at redshift 0.093. We investigate the impact of the complex cluster enviro…
Age-dating the Tully-Fisher relation at moderate redshift
Ignacio Ferreras, Asmus Böhm, Bodo Ziegler +1
We analyse the Tully-Fisher relation at moderate redshift from the point of view of the underlying stellar populations, by comparing optical and NIR photometry with a phenomenologi…
Interacting Galaxies in the A901/902 Supercluster with STAGES
A. L. Heiderman, S. Jogee, I. Marinova +22
We present a study of galaxy mergers and the influence of environment in the Abell 901/902 supercluster at z~0.165. We use HST ACS F606W data from the STAGES survey, COMBO-17, Spit…
Less than 10 percent of star formation in z=0.6 massive galaxies is triggered by major interactions
Aday R. Robaina, Eric F. Bell, Rosalind E. Skelton +26
Both observations and simulations show that major tidal interactions or mergers between gas-rich galaxies can lead to intense bursts of starformation. Yet, the average enhancement…
Optically-passive spirals: The missing link in gradual star formation suppression upon cluster infall
Christian Wolf, Alfonso Aragón-Salamanca, Michael Balogh +22
Galaxies migrate from the blue cloud to the red sequence when their star formation is quenched. Here, we report on galaxies quenched by environmental effects and not by mergers or…
Barred Galaxies in the Abell 901/2 Supercluster with STAGES
I. Marinova, S. Jogee, A. Heiderman +23
