A new population of recently quenched elliptical galaxies in the SDSS
Daniel H. McIntosh, Cory Wagner, Andrew Cooper +8
We use the Sloan Digital Sky Survey to investigate the properties of massive elliptical galaxies in the local Universe (z\leq0.08) that have unusually blue optical colors. Through…
Testing the Modern Merger Hypothesis via the Assembly of Massive Blue Elliptical Galaxies in the Local Universe
Tim Haines, D. H. McIntosh, S. F. Sánchez +2
The modern merger hypothesis offers a method of forming a new elliptical galaxy through merging two equal-mass, gas-rich disk galaxies fuelling a nuclear starburst followed by effi…
Resolved star formation and molecular gas properties of green valley galaxies: a first look with ALMA and MaNGA
Lihwai Lin, Francesco Belfiore, Hsi-An Pan +21
We study the role of cold gas in quenching star formation in the green valley by analysing ALMA CO (1-0) observations of three galaxies with resolved optical spectroscopy fr…
The Astropy Problem
Demitri Muna, Michael Alexander, Alice Allen +151
The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Pyth…
Binary-level Software Compatibility Tool Agreement
Vanessa Sochat, Tim Haines
Application Binary Interface (ABI) compatibility is essential for system or software updates to ensure that libraries continue to function. Tools that can assess a binary or librar…
Implications of a time-varying Galactic potential for determinations of the dynamical surface density
Tim Haines, Elena D'Onghia, Benoit Famaey +2
Recent studies have shown that the passage of a massive satellite through the disk of a spiral galaxy can induce vertical wobbles in the disk and produce features such as in-plane…
