IFUM Integrated Field Spectroscopy of Ten M104 Satellite Galaxy Candidates
Ethan Crosby, Mario Mateo, Ivanna Escala +3
We report the spectroscopic analysis of ten satellite galaxy candidates in the sphere of influence of the Sombrero galaxy (M104, NGC4594), based on data obtained with IFUM (Integra…
Eridanus III and DELVE 1: Carbon-rich Primordial Star Clusters or the Smallest Dwarf Galaxies?
Joshua D. Simon, Ting S. Li, Alexander P. Ji +8
We present spectroscopy of the ultra-faint Milky Way satellites Eridanus III (Eri III) and DELVE 1. We identify eight member stars in each satellite and place non-constraining uppe…
Elemental Abundances in And XIX From Coadded Spectra
L. R. Cullinane, Karoline M. Gilbert, Ivanna Escala +6
With a luminosity similar to that of Milky Way dwarf spheroidal (dSph) systems like Sextans, but a spatial extent similar to that of ultradiffuse galaxies (UDGs), Andromeda (And) X…
The structure of the stellar halo of the Andromeda galaxy explored with the NB515 for Subaru/HSC. I.: New Insights on the stellar halo up to 120 kpc
Itsuki Ogami, Mikito Tanaka, Yutaka Komiyama +16
We analyse the M31 halo and its substructure within a projected radius of 120 kpc using a combination of Subaru/HSC and CFHT/MegaCam - \& -…
