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...

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.

We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-generation Sloan Digital Sky Survey (SDSS-IV) that began on 2014 July 1....

Herschel-ATLAS: properties of dusty massive galaxies at low and high redshifts (2014)
Journal Article
Rowlands, K., Dunne, L., Dye, S., Aragón-Salamanca, A., Maddox, S., da Cunha, E., …Valiante, E. (2014). Herschel-ATLAS: properties of dusty massive galaxies at low and high redshifts. Monthly Notices of the Royal Astronomical Society, 441(2), https://doi.org/10.1093/mnras/stu510

We present a comparison of the physical properties of a rest-frame 250-μm-selected sample of massive, dusty galaxies from 0 < z < 5.3. Our sample comprises 29 high-redshift submillimetre galaxies (SMGs) from the literature and 843 dusty galaxies at z...

The dust budget crisis in high-redshift submillimetre galaxies (2014)
Journal Article
Rowlands, K., Gomez, H., Dunne, L., Aragón-Salamanca, A., Dye, S., Maddox, S., …van der Werf, P. (in press). The dust budget crisis in high-redshift submillimetre galaxies. Monthly Notices of the Royal Astronomical Society, 441(2), https://doi.org/10.1093/mnras/stu605

We apply a chemical evolution model to investigate the sources and evolution of dust in a sample of 26 high-redshift (z > 1) submillimetre galaxies (SMGs) from the literature, with complete photometry from ultraviolet to the submillimetre. We show th... Read More about The dust budget crisis in high-redshift submillimetre galaxies.

Ionized gas discs in elliptical and S0 galaxies at z < 1 (2014)
Journal Article
Jaffe, Y. L., Aragón-Salamanca, A., Ziegler, B., Kuntschner, H., Zaritsky, D., Rudnick, G., …Demarco, R. (2014). Ionized gas discs in elliptical and S0 galaxies at z < 1. Monthly Notices of the Royal Astronomical Society, 440(4), https://doi.org/10.1093/mnras/stu507

We analyse the extended, ionized-gas emission of 24 early-type galaxies (ETGs) at 0 < z < 1 from the ESO Distant Cluster Survey (EDisCS). We discuss different possible sources of ionization and favour star formation as the main cause of the observed... Read More about Ionized gas discs in elliptical and S0 galaxies at z < 1.
