New Evidence for a Flux-independent Spectral Index of Sgr A* in the Near-infrared
Hadrien Paugnat, Tuan Do, Abhimat K. Gautam +11
In this work, we measure the spectral index of Sagittarius A* (Sgr A*) between the (1.6 m) and (2.2 m) broadband filters in the near-infrared (NIR), sampling o…
Hawking Radiation from non-evaporating primordial black holes cannot enable the formation of direct collapse black holes
Jonathan Regan, Marios Kalomenopoulos, Kelly Kosmo O'Neil
The formation of supermassive black holes (SMBHs) in the early Universe is a subject of significant debate. In this study, we examine whether non-evaporating primordial black holes…
Orbital and Atmospheric Characterization of the 1RXS J034231.8+121622 System Using High-Resolution Spectroscopy Confirms That The Companion is a Low-Mass Star
Clarissa R. Do Ó, Ben Sappey, Quinn M. Konopacky +33
The 1RXS J034231.8+121622 system consists of an M dwarf primary and a directly imaged low-mass stellar companion. We use high resolution spectroscopic data from Keck/KPIC to estima…
