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…
