If dark matter is fuzzy, the first stars form in massive pancakes
Mihir Kulkarni, Eli Visbal, Greg L. Bryan +1
Fuzzy dark matter (FDM) is a proposed modification for the standard cold dark matter (CDM) model motivated by small-scale discrepancies in low-mass galaxies. Composed of ultra-ligh…
Propagation of a Strong Fast Magnetosonic Wave in the Magnetosphere of a Neutron Star
Alexander Y. Chen, Yajie Yuan, Xinyu Li +1
We study the propagation of a strong, low frequency, linearly polarized fast magnetosonic wave inside the magnetosphere of a neutron star. The relative strength of the wave…
An Intermediate-field Fast Radio Burst Model and the Quasi-periodic Oscillation
Jieshuang Wang, Xinyu Li, Zigao Dai +1
Quasi-periodic oscillation (QPO) signals are discovered in some fast radio bursts (FRBs) such as FRB 20191221A, as well as in the X-ray burst associated with the galactic FRB from…
Quantum fluctuations masquerade as halos: Bounds on ultra-light dark matter from quadruply-imaged quasars
Alexander Laroche, Daniel Gilman, Xinyu Li +2
Ultra-light dark matter (ULDM) refers to a class of theories, including ultra-light axions, in which particles with mass comprise a significant fraction…
Dynamical Effects of Colliding Outflows in Binary Systems
Lile Wang, Xinyu Li
The outflow of an object traveling in a fluid can shape the fluid morphology by forming a forward bow shock which accelerates the object via gravitational feedback. This dynamical…
