Self-interacting dark matter without prejudice
Nicolás Bernal, Xiaoyong Chu, Suchita Kulkarni +1
The existence of dark matter particles that carry phenomenologically relevant self-interaction cross sections mediated by light dark sector states is considered to be severely cons…
A Practical and Consistent Parametrization of Dark Matter Self-Interactions
Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama
Self-interacting dark matter has been proposed to explain the apparent mass deficit in astrophysical small-scale halos, while observations from galaxy clusters suggest that the cor…
Stellar probes of dark sector-photon interactions
Xiaoyong Chu, Jui-Lin Kuo, Josef Pradler +1
Electromagnetically neutral dark sector particles may directly couple to the photon through higher dimensional effective operators. Considering electric and magnetic dipole moment,…
Finite-size dark matter and its effect on small-scale structure
Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama
If dark matter has a finite size that is larger than its Compton wavelength, the corresponding self-interaction cross section decreases with the velocity. We investigate the implic…
