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 rise…

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…

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…

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…

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…

HST Low Resolution Stellar Library

Tathagata Pal, Islam Khan, Guy Worthey +2

Hubble Space Telescope's (HST) Space Telescope Imaging Spectrograph (STIS) targeted 556 stars in a long-running program called Next Generation Spectral Library (NGSL) via proposals…
