Journal Article
Albareti, F. D., Prieto, C. A., Almeida, A., Anders, F., Anderson, S., Andrews, B. H., …and 125 authors. (2017). The 13th data release of the Sloan Digital Sky Survey: first spectroscopic data from the SDSS-IV survey mapping nearby galaxies at Apache Point Observatory. Astrophysical Journal Supplement, 233(2), https://doi.org/10.3847/1538-4365/aa8992

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in 2014 July. It pursues three core programs: the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2), Mapping Nearby Galaxies at APO (MaNGA), and the...

Determining the halo mass scale where galaxies lose their gas (2017)
Journal Article
Rudnick, G., Jablonka, P., Moustakas, J., Aragón-Salamanca, A., Zaritsky, D., Jaffe, Y. L., De Lucia, G., Desai, V., Halliday, C., Just, D., Milvang-Jensen, B., & Poggianti, B. (2017). Determining the halo mass scale where galaxies lose their gas. Astrophysical Journal, 850(2), Article 181. https://doi.org/10.3847/1538-4357/aa866c

A major question in galaxy formation is how the gas supply that fuels activity in galaxies is modulated by their environment. We use spectroscopy of a set of well characterized clusters and groups at $0.45$AA is $f_{[OII]}=0.08^{+0.03}_{-0.02}$ and $...

OMEGA - OSIRIS mapping of emission-line galaxies in A901/2: III. - Galaxy properties across projected phase space in A901/2 (2017)
Journal Article
Weinzirl, T., Aragón-Salamanca, A., Gray, M. E., Bamford, S. P., Rodriguez Del Pino, B., Chies-Santos, A. L., …Cool, R. J. (2017). OMEGA - OSIRIS mapping of emission-line galaxies in A901/2: III. - Galaxy properties across projected phase space in A901/2. Monthly Notices of the Royal Astronomical Society, 471(1), 182-200. https://doi.org/10.1093/mnras/stx1525

We conduct a comprehensive projected phase-space analysis of the A901/2 multicluster system at z ∼ 0.165. Aggregating redshifts from spectroscopy, tunable-filter imaging and prism techniques, we assemble a sample of 856 cluster galaxies reaching 108....

The effect of the environment on the structure, morphology and star-formation history of intermediate-redshift galaxies (2017)
Journal Article
Kelkar, K., Gray, M. E., Aragón-Salamanca, A., Rudnick, G., Milvang-Jensen, B., Jablonka, P., & Schrabback, T. (2017). The effect of the environment on the structure, morphology and star-formation history of intermediate-redshift galaxies. Monthly Notices of the Royal Astronomical Society, 469(4), 4551-4564. https://doi.org/10.1093/mnras/stx1155

With the aim of understanding the effect of the environment on the star formation history and morphological transformation of galaxies, we present a detailed analysis of the colour, morphology and internal structure of cluster and field galaxies at 0...
