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…

Simulating the Milky Way bar and bulge with an initially Sérsic disc
N. Deg, Victor P. Debattista, Lawrence Widrow +3
We model the formation of a bar plus box/peanut bulge (BP bulge) component in a Milky Way-like disc galaxy using simulations of isolated multi-component systems that evolve from eq…

Empirical Modeling of Magnetic Braking in Millisecond Pulsars to Measure the Local Dark Matter Density and Effects of Orbiting Satellite Galaxies
Thomas Donlon, Sukanya Chakrabarti, Sophia Vanderwaal +3
We present a novel method that enables us to estimate the acceleration of individual millisecond pulsars (MSPs) using only their spin period and its time derivative. For our binary…
