Dark matter self-interactions from the internal dynamics of dwarf spheroidals
Mauro Valli, Hai-Bo Yu
Dwarf spheroidal galaxies provide well-known challenges to the standard cold and collisionless dark matter scenario: The too-big-to-fail problem, namely the mismatch between the ob…
Hubble Parameter and Baryon Acoustic Oscillation Measurement Constraints on the Hubble Constant, the Deviation from the Spatially-Flat cdm Model, The Deceleration-Acceleration Transition Redshift, and Spatial Curvature
Hai Yu, Bharat Ratra, Fa-Yin Wang
We compile a complete collection of reliable Hubble parameter data to redshift and use them with the Gaussian Process method to determine continuous fun…
Signatures of Self-Interacting Dark Matter in the Matter Power Spectrum and the CMB
Ran Huo, Manoj Kaplinghat, Zhen Pan +1
We consider a self-interacting dark matter model in which the massive dark photon mediating the self-interaction decays to light dark fermions to avoid over-closing the universe. W…
Neutron stars at the dark matter direct detection frontier
Nirmal Raj, Philip Tanedo, Hai-Bo Yu
Neutron stars capture dark matter efficiently. The kinetic energy transferred during capture heats old neutron stars in the local galactic halo to temperatures detectable by upcomi…
Statistical Distributions of Optical Flares from Gamma-Ray Bursts
Shuang-Xi Yi, Hai Yu, F. Y. Wang +1
We statistically study gamma-ray burst (GRB) optical flares from the Swift/UVOT catalog. We compile 119 optical flares, including 77 flares with redshift measurements. Some tight c…
A Monte Carlo Approach to Magnetar-powered Transients: I. Hydrogen-deficient Superluminous Supernovae
Liang-Duan Liu, Shan-Qin Wang, Ling-Jun Wang +3
In this paper we collect 19 hydrogen-deficient superluminous supernovae (SLSNe) and fit their light curves, temperature evolution, and velocity evolution based on the magnetar-powe…
