An Acceleration is Worth a Hundred Thousand Phase Space Measurements
Thomas Donlon, Sukanya Chakrabarti, Elena D'Onghia
It is now possible to directly measure the accelerations that arise from the distribution of (dark) matter in the Milky Way. These acceleration-based measurements of the local dark…
Weighing the Milky Way's Satellite Galaxies Using Pulsar Accelerations
Thomas Donlon, Sukanya Chakrabarti, Jason A. S. Hunt
The properties of dwarf galaxies orbiting the Milky Way (MW) are useful for testing models of the formation of our Galaxy, and by extension various theories of cosmology. Recent ef…
Mean Mass Density near the Sun from the Divergence Theorem and Pulsar Accelerations
Thomas Donlon, Lawrence M. Widrow, Sukanya Chakrabarti
We introduce a new, non-parametric method for estimating the mass enclosed within a sphere of arbitrary radius centered on the Sun. The method is based on the divergence theorem as…
Chemical Components in the Virgo Overdensity and Hercules-Aquila Cloud: hints of more than one merger event in GSE-like debris
Haoyang Liu, Cuihua Du, Thomas Donlon +1
Using elemental abundances for 1.26 million K giants in the LAMOST DR8 value-added catalog, we analyze the chemical abundances of the Virgo Overdensity (VOD) and Hercules-Aquila Cl…
The imprint of dark matter on the Galactic acceleration field
Arpit Arora, Robyn E. Sanderson, Sukanya Chakrabarti +6
Measurements of the accelerations of stars enabled by time-series extreme-precision spectroscopic observations, from pulsar timing, and from eclipsing binary stars in the Solar Nei…
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…
