The APOGEE Library of Infrared SSP Templates (A-LIST): High-Resolution Simple Stellar Population Spectral Models in the H-Band
Aishwarya Ashok, Gail Zasowski, Anil Seth +8
Integrated light spectroscopy from galaxies can be used to study the stellar populations that cannot be resolved into individual stars. This analysis relies on stellar population s…
The Elusive Distance Gradient in the Ultra-Faint Dwarf Galaxy Hercules: A Combined Hubble Space Telescope and Gaia View
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +6
The ultra-faint dwarf galaxy Hercules has an extremely elongated morphology with both photometric overdensities and kinematic members at large radii, suggesting that it may be tida…
Revealing the intermediate-mass black hole at the heart of the dwarf galaxy NGC 404 with sub-parsec resolution ALMA observations
Timothy A. Davis, Dieu D. Nguyen, Anil C. Seth +15
We estimate the mass of the intermediate-mass black hole at the heart of the dwarf elliptical galaxy NGC 404 using Atacama Large Millimeter/submillimeter Array (ALMA) observations…
Nuclear X-ray Activity in Low-Surface-Brightness Galaxies: Prospects for Constraining the Local Black Hole Occupation Fraction with a Chandra Successor Mission
Edmund Hodges-Kluck, Elena Gallo, Anil Seth +2
About half of nearby galaxies have a central surface brightness >1 magnitude below that of the sky. The overall properties of these low-surface-brightness galaxies (LSBGs) remain u…
Asymmetric spatial distribution of sub-solar metallicity stars in the Milky Way nuclear star cluster
A. Feldmeier-Krause, W. Kerzendorf, T. Do +10
We present stellar metallicity measurements of more than 600 late-type stars in the central 10 pc of the Galactic centre. Together with our previously published KMOS data, this dat…
A Gaia-based catalog of candidate stripped nuclei and luminous globular clusters in the halo of Centaurus A
Karina T. Voggel, Anil C. Seth, David J. Sand +4
Tidally stripped galaxy nuclei and luminous globular clusters (GCs) are important tracers of the halos and assembly histories of nearby galaxies, but are difficult to reliably iden…
