Constraints on a dark matter sub-halo near the Sun from pulsar timing
Sukanya Chakrabarti, Philip Chang, Stefano Profumo +1
Using pulsar accelerations, we identify and constrain the properties of a dark matter sub-halo in the Galaxy for the first time from analyzing the acceleration field of binary and…

A map of the outer gas disk of the Galaxy with direct distances from young stars
Peter Craig, Sukanya Chakrabarti, Alexander R. Pettitt +2
For more than fifty years, astronomers have mapped the neutral hydrogen gas in the Galaxy assuming kinematically derived distances. We employ the distances of nearby young stars, w…

The Symbiotic Recurrent Nova V745 Sco at Radio Wavelengths
Isabella Molina, Laura Chomiuk, Justin D. Linford +14
V745 Sco is a Galactic symbiotic recurrent nova with nova eruptions in 1937, 1989 and 2014. We study the behavior of V745 Sco at radio wavelengths (0.6-37,GHz), covering both its 1…
