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…

Galactic Structure From Binary Pulsar Accelerations: Beyond Smooth Models
Thomas Donlon, Sukanya Chakrabarti, Lawrence M. Widrow +3
We measure the line-of-sight accelerations of 26 binary pulsars due to the Milky Way's gravitational potential, and produce a 3-dimensional map of the acceleration field of the Gal…
