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…
The far side of the Galactic bar/bulge revealed through semi-regular variables
Daniel R. Hey, Daniel Huber, Benjamin J. Shappee +8
The Galactic bulge and bar are critical to our understanding of the Milky Way. However, due to the lack of reliable stellar distances, the structure and kinematics of the bulge/bar…
Orientations of DM Halos in FIRE-2 Milky Way-mass Galaxies
Jay Baptista, Robyn Sanderson, Dan Huber +11
The shape and orientation of dark matter (DM) halos are sensitive to the micro-physics of the DM particle, yet in many mass models, the symmetry axes of the Milky Way's DM halo are…
Building an Acceleration Ladder with Tidal Streams and Pulsar Timing
Peter Craig, Sukanya Chakrabarti, Robyn E. Sanderson +1
We analyze stellar streams in action-angle coordinates combined with recent local direct acceleration measurements to provide joint constraints on the potential of our Galaxy. Our…
Low-density star cluster formation: discovery of a young faint fuzzy on the outskirts of the low-mass spiral galaxy NGC 247
Aaron J. Romanowsky, Søren S. Larsen, Alexa Villaume +21
The classical globular clusters found in all galaxy types have half-light radii of 2-4 pc, which have been tied to formation in the dense cores of giant molecular…
A non-interacting Galactic black hole candidate in a binary system with a main-sequence star
Sukanya Chakrabarti, Joshua D. Simon, Peter A. Craig +10
We describe the discovery of a solar neighborhood (d=468 pc) binary system with a main-sequence sunlike star and a massive non-interacting black hole candidate. The spectral energy…
