Stellar Populations with MaNGA: Iron Kink and Nitrogen Fuzz
Guy Worthey, Tathagata Pal
Recent analysis of 2968 MaNGA early type galaxies has yielded two notable trends with velocity dispersion () not previously discussed in the literature. First, Fe abundance ris…
Radial Gradients and Intrinsic Scatter in MaNGA Galaxies
Tathagata Pal, Guy Worthey
We derive stellar population parameters and radial gradients within 0.65 for spatially resolved spectra of 2968 early-type galaxies from MaNGA, spanning stellar velocity disp…
Revealing the Origins of Galactic Globular Clusters via Their Mg-Al Abundances
Shihui Lin, Baitian Tang, Genghao Liu +4
Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifyin…
On the Age Calibration of Open Clusters using Red Clump Stars
Abigail R. Chriss, Guy Worthey
In this study, we extend the dust-independent Hatzidimitriou (1991) relation between cluster age and color difference between the red giant branch (RGB) and red clump to…
The Morphology of Dwarf Galaxies Hosting Variable Active Galactic Nuclei
Erin Kimbro, Vivienne Baldassare, Guy Worthey +2
We analyze Hubble Space Telescope (HST) optical imaging of eight low-mass galaxies hosting active galactic nuclei (AGN) identified via their photometric variability in \cite{baldas…
