Micrometeoroid Impact Rate Analysis for an Artemis-Era Lunar Base
Daniel A. Yahalomi, Matthew T. Scoggins, Nasiah Anderson +5
NASA's Artemis Mission aims to return astronauts to the Moon and establish a base at the lunar south pole. A key challenge is understanding the threat from micrometeoroid impacts,…
Heavy black hole seed survivors in dwarf galaxies: a case study of Leo I
Matthew T. Scoggins, Zoltan Haiman, Fabio Pacucci
The supermassive black holes (SMBHs) with mass hosted by high-redshift galaxies have challenged our understanding of black hole formation and grow…
Learning the Universe: Tests of a Field Level -body Simulation Emulator
Matthew T. Scoggins, Matthew Ho, Francisco Villaescusa-Navarro +3
We apply and test a field-level emulator for non-linear cosmic structure formation in a volume matching next-generation surveys. Inferring the cosmological parameters and initial c…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
APOGEE Net: Improving the derived spectral parameters for young stars through deep learning
Richard Olney, Marina Kounkel, Chad Schillinger +6
Machine learning allows efficient extraction of physical properties from stellar spectra that have been obtained by large surveys. The viability of ML approaches has been demonstra…
