Comparison of the Stellar Populations of Bulges and Discs using the MaNGA Survey
Philip Lah, Nicholas Scott, Tania M. Barone +4
We use the MaNGA integral-field spectroscopic survey of low-redshift galaxies to compare the stellar populations of the bulge and disc components, identified from their Sersic prof…
SAMI-HI: The HI view of the H Tully-Fisher relation and data release
Barbara Catinella, Luca Cortese, Alfred L. Tiley +15
We present SAMI-HI, a survey of the atomic hydrogen content of 296 galaxies with integral field spectroscopy available from the SAMI Galaxy Survey. The sample spans nearly 4 dex in…
The SAMI Galaxy Survey: Using concentrated star-formation and stellar population ages to understand environmental quenching
Di Wang, Scott M. Croom, Julia J. Bryant +16
We study environmental quenching using the spatial distribution of current star-formation and stellar population ages with the full SAMI Galaxy Survey. By using a star-formation co…
The SAMI Galaxy Survey: flipping of the spin-filament alignment correlates most strongly with growth of the bulge
Stefania Barsanti, Matthew Colless, Charlotte Welker +8
We study the alignments of galaxy spin axes with respect to cosmic web filaments as a function of various properties of the galaxies and their constituent bulges and discs. We expl…
The SAMI galaxy survey: galaxy size can explain the offset between star-forming and passive galaxies in the mass-metallicity relationship
Sam P. Vaughan, Tania M. Barone, Scott M. Croom +14
In this work, we investigate how the central stellar metallicity ([Z/H]) of 1363 galaxies from the SAMI galaxy survey is related to their stellar mass and a proxy for the gravitati…
The Astropy Project: Sustaining and Growing a Community-oriented Open-source Project and the Latest Major Release (v5.0) of the Core Package
The Astropy Collaboration, Adrian M. Price-Whelan, Pey Lian Lim +133
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…
