We present an overview of and first results from the OMEGA (OSIRIS Mapping of Emission-line Galaxies in the multicluster system A901/2) survey. The ultimate goal of this project is to study star formation and active galactic nucleus (AGN) activity ac... Read More about OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2: I.

GLACE survey: OSIRIS/GTC tuneable filter Hα imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z=0.395 (2015)
Journal Article
Sánchez-Portal, M., Pintos-Castro, I., Pérez-Martínez, R., Cepa,, J., Pérez García, A., Domínguez-Sánchez, H., …Valtchanov, I. (2015). GLACE survey: OSIRIS/GTC tuneable filter Hα imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z=0.395. Astronomy and Astrophysics, 578, Article A30. https://doi.org/10.1051/0004-6361/201525620

The cores of clusters at 0 ≲ z ≲ 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type galaxies. Clusters grow through the accretion of galaxies and groups from the surrounding field, which implies...

Galaxy sizes as a function of environment at intermediate redshift from the ESO Distant Cluster Survey (2015)
Journal Article
Kelkar, K., Aragón-Salamanca, A., Gray, M., Maltby, D., Vulcani, B., De Lucia, G., Poggianti, B., & Zaritsky, D. (2015). Galaxy sizes as a function of environment at intermediate redshift from the ESO Distant Cluster Survey. Monthly Notices of the Royal Astronomical Society, 450(2), https://doi.org/10.1093/mnras/stv670

In order to assess whether the environment has a significant effect on galaxy sizes, we compare the mass–size relations of cluster and field galaxies in the 0.4<z<0.8 red-shift range from the ESO Distant Cluster Survey (EDisCS) using Hubble Space Tel...

The environmental dependence of the structure of galactic discs in STAGES S0 galaxies: implications for S0 formation (2015)
Journal Article
Maltby, D. T., Aragón-Salamanca, A., Gray, M. E., Hoyos, C., Wolf, C., Jogee, S., & Böhm, A. (in press). The environmental dependence of the structure of galactic discs in STAGES S0 galaxies: implications for S0 formation. Monthly Notices of the Royal Astronomical Society, 447(2), https://doi.org/10.1093/mnras/stu2536

We present an analysis of V-band radial surface brightness μ(r) profiles for S0 galaxies in different environments using Hubble Space Telescope/Advanced Camera for Surveys imaging and data from the Space Telescope A901/2 Galaxy Evolution Survey. Usin... Read More about The environmental dependence of the structure of galactic discs in STAGES S0 galaxies: implications for S0 formation.
