OMEGA -- OSIRIS Mapping of Emission-line Galaxies in A901/2 -- V. The rich population of jellyfish galaxies in the multi-cluster system Abell 901/2
Fernanda V. Roman-Oliveira, Ana L. Chies-Santos, Bruno Rodríguez del Pino +3
We present the results of a systematic search and characterisation of jellyfish galaxy candidates in the multi-cluster system A901/2, at z ~ 0.165, as part of the OMEGA survey. By…
OMEGA - OSIRIS Mapping of Emission-line Galaxies in A901/2: IV. - Extinction of Star-Formation Estimators with Inclination
Christian Wolf, Tim Weinzirl, Alfonso Aragón-Salamanca +6
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…
Galaxy Cluster Mass Reconstruction Project - IV. Understanding the effects of imperfect membership on cluster mass estimation
R. Wojtak, L. Old, G. A. Mamon +17
The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the lin…
Galaxy Zoo: constraining the origin of spiral arms
Ross E. Hart, Steven P. Bamford, William C. Keel +4
Since the discovery that the majority of low-redshift galaxies exhibit some level of spiral structure, a number of theories have been proposed as to why these patterns exist. A pop…
Galaxy Zoo: Morphological classification of galaxy images from the Illustris simulation
Hugh Dickinson, Lucy Fortson, Chris Lintott +13
Modern cosmological simulations model the universe with increasing sophistication and at higher spatial and temporal resolutions. These enhancements permit detailed comparisons bet…
The Astropy Project: Building an inclusive, open-science project and status of the v2.0 core package
The Astropy Collaboration, A. M. Price-Whelan, B. M. Sipőcz +134
The Astropy project supports and fosters the development of open-source and openly-developed Python packages that provide commonly-needed functionality to the astronomical communit…
