The fastest stars in the Galaxy
Kareem El-Badry, Ken J. Shen, Vedant Chandra +18
We report a spectroscopic search for hypervelocity white dwarfs (WDs) that are runaways from Type Ia supernovae (SNe Ia) and related thermonuclear explosions. Candidates are select…
A 4-8 GHz Galactic Center Search for Periodic Technosignatures
Akshay Suresh, Vishal Gajjar, Pranav Nagarajan +6
Radio searches for extraterrestrial intelligence have mainly targeted the discovery of narrowband continuous-wave beacons and artificially dispersed broadband bursts. Periodic puls…
Spectroscopic follow-up of black hole and neutron star candidates in ellipsoidal variables from Gaia DR3
Pranav Nagarajan, Kareem El-Badry, Antonio C. Rodriguez +2
We present multi-epoch spectroscopic follow-up of a sample of ellipsoidal variables selected from Gaia DR3 as candidates for hosting quiescent black holes (BHs) and neutron stars (…
RR Lyrae-based Distances for 39 Nearby Dwarf Galaxies Calibrated to Gaia eDR3
Pranav Nagarajan, Daniel R. Weisz, Kareem El-Badry
We provide uniform RR Lyrae-based distances to 39 dwarf galaxies in and around the Local Group. We determine distances based on a Bayesian hierarchical model that uses periods and…
