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…
LensWatch: I. Resolved HST Observations and Constraints on the Strongly-Lensed Type Ia Supernova 2022qmx ("SN Zwicky")
J. D. R. Pierel, N. Arendse, S. Ertl +39
Supernovae (SNe) that have been multiply-imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools…
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…
Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021
Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…
