OMEGA – OSIRIS mapping of emission-line galaxies in A901/2 : II. Environmental influence on integrated star formation properties and AGN activity
Rodríguez del Pino, Bruno; Aragón-Salamanca, Alfonso; Chies-Santos, Ana Leonor; Weinzirl, Timothy; Bamford, Steven Peter; Gray, Meghan E.; Böhm, Asmus; Wolf, Christian; Maltby, David T. (2017) [Artigo de periódico]We present a study of the star formation and AGN activity for galaxies in CP 15051 the Abell 901/2 multicluster system at z ∼ 0.167 as part of the OSIRIS Mapping of Emission-line Galaxies in A901/2 (OMEGA) survey. Using ... -
OMEGA – OSIRIS mapping of emission-line galaxies in A901/2 : III. Galaxy properties across projected phase space in A901/2
Weinzirl, Timothy; Aragón-Salamanca, Alfonso; Gray, Meghan E.; Bamford, Steven Peter; Rodríguez del Pino, Bruno; Chies-Santos, Ana Leonor; Böhm, Asmus; Wolf, Christian; Cool, Richard J. (2017) [Artigo de periódico]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 ... -
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
Chies-Santos, Ana Leonor; Rodríguez del Pino, Bruno; Aragón-Salamanca, Alfonso; Bamford, Steven Peter; Gray, Meghan E.; Wolf, Christian; Böhm, Asmus; Maltby, David T.; Pintos Castro, Irene; Sánchez-Portal, Miguel; Weinzirl, Timothy (2015) [Artigo de periódico]We present an overview of and first results from the OMEGA (OSIRIS Mapping of Emissionline Galaxies in the multicluster system A901/2) survey. The ultimate goal of this project is to study star formation and active galactic ... -
OMEGA – OSIRIS mapping of emission-line galaxies in A901/2 : IV. Extinction of star formation estimators with inclination
Wolf, Christian; Weinzirl, Timothy; Aragón-Salamanca, Alfonso; Gray, Meghan E.; Rodríguez del Pino, Bruno; Chies-Santos, Ana Leonor; Bamford, Steven Peter; Böhm, Asmus; Harborne, Katherine (2018) [Artigo de periódico]We study the effect of inclination on the apparent brightness of star-forming galaxies in spectral passbands that are commonly used as star formation indicators. As diagnostics we use mass-to-light ratios in three passbands: ... -
OMEGA–OSIRIS mapping of emission-line galaxies in A901/2–V : the rich population of jellyfish galaxies in the multicluster system Abell 901/2
Oliveira, Fernanda Vitória Roman de; Chies-Santos, Ana Leonor; Rodríguez del Pino, Bruno; Aragón-Salamanca, Alfonso; Gray, Meghan E.; Bamford, Steven Peter (2019) [Artigo de periódico]We present the results of a systematic search and characterization of galaxies with morphological signatures of ram pressure stripping, known as jellyfish galaxies, in the multicluster system A901/2, at z ~ 0.165, as part ... -
The SLUGGS survey : chromodynamical modelling of the lenticular galaxy NGC 1023
Cortesi, Arianna; Chies-Santos, Ana Leonor; Pota, Vincenzo; Foster, Caroline; Coccato, Lodovico; Oliveira, Claudia Lucia Mendes de; Forbes, Duncan Alan; Merrifield, Michael; Bamford, Steven Peter; Romanowsky, Aaron J.; Brodie, Jean P.; Kartha, Sreeja S.; Alabi, Adebusola B.; Proctor, Robert Neil; Almeida, Andres (2016) [Artigo de periódico]Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper, we present a new catalogue of GC velocities ... -
Wavelength self-calibration and sky subtraction for Fabry-Pérot interferometers : applications to OSIRIS
Weinzirl, Timothy; Aragón-Salamanca, Alfonso; Bamford, Steven Peter; Rodríguez del Pino, Bruno; Gray, Meghan E.; Chies-Santos, Ana Leonor (2015) [Artigo de periódico]We describe techniques concerning wavelength calibration and sky subtraction to maximize the scientific utility of data from tunable filter instruments. While we specifically address data from the Optical System for Imaging ...
