SDSS-IV MaNGA: Spatially resolved star formation histories in galaxies as a function of galaxy mass and type
Daniel Goddard, Daniel Thomas, Claudia Maraston +25
We study the internal gradients of stellar population properties within for a representative sample of 721 galaxies with stellar masses ranging between $10^{9}\;M_…
SDSS-IV MaNGA: stellar population gradients as a function of galaxy environment
Daniel Goddard, Daniel Thomas, Claudia Maraston +23
We study the internal radial gradients of stellar population properties within and analyse the impact of galaxy environment. We use a representative sample of 721…
APOGEE Chemical Abundances of Globular Cluster Giants in the Inner Galaxy
Ricardo P. Schiavon, Jennifer A. Johnson, Peter M. Frinchaboy +27
We report chemical abundances obtained by SDSS-III/APOGEE for giant stars in five globular clusters located within 2.2 kpc of the Galactic centre. We detect the presence of multipl…
SDSS-IV MaNGA: Bulge-Disc Decomposition of IFU Datacubes (BUDDI)
Evelyn J. Johnston, Boris Haeussler, Alfonso Aragon-Salamanca +12
With the availability of large integral-field unit (IFU) spectral surveys of nearby galaxies, there is now the potential to extract spectral information from across the bulges and…
Two Groups of Red Giants with Distinct Chemical Abundances in the Bulge Globular Cluster NGC 6553 Through the Eyes of APOGEE
Baitian Tang, Roger E. Cohen, Doug Geisler +18
Multiple populations revealed in globular clusters (GCs) are important windows to the formation and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are…
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…
