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…
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…
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…
Scattered Light in STIS Grating G230LB
Guy Worthey, Tathagata Pal, Islam Khan +2
The G230LB grating used with STIS's CCD detector scatters red light. In red objects, the scattered light mingles with the ultraviolet signal, causing spurious short-wavelength flux…
Individual element sensitivity for stellar evolutionary isochrones
Guy Worthey, Xiang Shi, Tathagata Pal +2
Stellar evolution calculations with variable abundance ratios were used to gauge the effects on temperatures, luminosities, and lifetimes in various phases. Individual elements C,…
The frequency by mass of Galactic carbon stars inferred from Gaia measurements of star cluster members
Tathagata Pal, Guy Worthey
We investigate the frequency of occurrence of Galactic carbon stars as a function of progenitor mass using Gaia data. Small number statistics limit fidelity, but C star frequency a…
