Mapping the Milky Way in 5-D with 170 Million Stars

Joshua S. Speagle, Catherine Zucker, Ana Bonaca +18

We present "augustus", a catalog of distance, extinction, and stellar parameter estimates to 170 million stars from and with dr…

Half a Million M Dwarf Stars Characterized Using Domain-Adapted Spectral Analysis

Shuo Zhang, Hua-Wei Zhang, Yuan-Sen Ting +5

We present fundamental atmospheric parameters (Teff and log g) and metallicities ([M/H]) for 507,513 M dwarf stars using low-resolution spectra (R~1800) from LAMOST DR10. By employ…

Ancient Very Metal-Poor Stars Associated With the Galactic Disk in the H3 Survey

Courtney Carter, Charlie Conroy, Dennis Zaritsky +8

Ancient, very metal-poor stars offer a window into the earliest epochs of galaxy formation and assembly. We combine data from the H3 Spectroscopic Survey and Gaia to measure metall…

Tame hereditary path algebras and amenability

Sebastian Eckert

In this note we are concerned with the notion of amenable representation type as defined in a recent paper by Gábor Elek. Roughly speaking, an algebra is of amenable type if for al…
