Observations of Five Southern-Hemisphere Cataclysmic Binary Stars
John R. Thorstensen, Annabelle E. Niblett, Shreya Gandhi +7
We present observations and analyses of five little-studied cataclysmic binary stars in the southern celestial hemisphere. Our new observations are from the South African Astronomi…
Identifying Dwarfs of MC Analog GalaxiEs (ID-MAGE): The Search for Satellites Around Low-Mass Hosts
Laura Congreve Hunter, Burçin Mutlu-Pakdil, David J. Sand +11
We present results from ID-MAGE (Identifying Dwarfs of MC Analog GalaxiEs), a survey aimed at identifying and characterizing unresolved satellite galaxies around 36~nearby LMC- and…
Evidence for evolutionary pathway-dependent black hole scaling relations
Jonathan H. Cohn, Emmanuel Durodola, Quinn O. Casey +2
Recent observations have identified an abundance of high-redshift active galactic nuclei (AGN) with supermassive black holes (BHs) that are over-massive compared to the local BH ma…
Emission Modeling in the EHT-ngEHT Age
Richard Anantua, Joaquín Dúran, Nathan Ngata +9
This work proposes a methodology to test phenomenologically-motivated emission processes that account for the flux and polarization distribution and global structure of the 230 GHz…
