Tilted Dark Halos are Common, Long-Lived, and can Warp Galactic Disks
Jiwon Jesse Han, Vadim Semenov, Charlie Conroy +1
In the -CDM paradigm, the dark halo governs the gravitational potential within which a galaxy can form and evolve. In this Letter we show that the present-day inner ($r<50\text{…
A Tilted Dark Halo Origin of the Galactic Disk Warp and Flare
Jiwon Jesse Han, Charlie Conroy, Lars Hernquist
The outer disk of the Milky Way Galaxy is warped and flared. Several mechanisms have been proposed to explain these phenomena, but none have quantitatively reproduced both features…
The fastest stars in the Galaxy
Kareem El-Badry, Ken J. Shen, Vedant Chandra +18
We report a spectroscopic search for hypervelocity white dwarfs (WDs) that are runaways from Type Ia supernovae (SNe Ia) and related thermonuclear explosions. Candidates are select…
Discovery of the Magellanic Stellar Stream Out to 100 Kiloparsecs
Vedant Chandra, Rohan P. Naidu, Charlie Conroy +7
The Magellanic Stream (MS) - an enormous ribbon of gas spanning of the southern sky trailing the Magellanic Clouds - has been exquisitely mapped in the five decades sin…
RomAndromeda: The Roman Survey of the Andromeda Halo
Arjun Dey, Joan Najita, Carrie Filion +50
As our nearest large neighbor, the Andromeda Galaxy provides a unique laboratory for investigating galaxy formation and the distribution and substructure properties of dark matter…
NANCY: Next-generation All-sky Near-infrared Community surveY
Jiwon Jesse Han, Arjun Dey, Adrian M. Price-Whelan +206
The Nancy Grace Roman Space Telescope is capable of delivering an unprecedented all-sky, high-spatial resolution, multi-epoch infrared map to the astronomical community. This oppor…
