Confronting the Diversity Problem: The Limits of Galaxy Rotation Curves as a tool to Understand Dark Matter Profiles
Isabel S. Sands, Philip F. Hopkins, Xuejian Shen +9
While galaxy rotation curves provide one of the most powerful methods for measuring dark matter profiles in the inner regions of rotation-supported galaxies, at the dwarf scale the…
The Rise of the -Process in the Gaia-Sausage/Enceladus Dwarf Galaxy
Xiaowei Ou, Alexander P. Ji, Anna Frebel +2
Neutron star mergers (NSMs) produce copious amounts of heavy r-process elements after a time delayed inspiral process. Once NSMs are present in a galaxy, r-process elements, such a…
Signatures of tidal disruption of the Hercules ultra-faint dwarf galaxy
Xiaowei Ou, Anirudh Chiti, Nora Shipp +6
The Hercules ultra-faint dwarf galaxy (UFD) has long been hypothesized to be tidally disrupting, yet no conclusive evidence has been found for tidal disruption owing partly to diff…
Synthetic Gaia DR3 surveys from the FIRE cosmological simulations of Milky-Way-mass galaxies
Tri Nguyen, Xiaowei Ou, Nondh Panithanpaisal +4
The third data release (DR3) of Gaia has provided a five-fold increase in the number of radial velocity measurements of stars, as well as a stark improvement in parallax and proper…
The dark matter profile of the Milky Way inferred from its circular velocity curve
Xiaowei Ou, Anna-Christina Eilers, Lina Necib +1
In this paper, we construct the circular velocity curve of the Milky Way out to kpc, providing an updated model of the dark matter density profile. We derive precise para…
