Detecting Dark Matter Substructures on Small Scales with Fast Radio Bursts
Huangyu Xiao, Liang Dai, Matthew McQuinn
We propose measuring the arrival time difference of Fast Radio Bursts (FRBs) along two adjacent sightlines as a new probe to dark matter substructures on scales down to A…
Dark Matter Is The New BBN
Dan Hooper, Huangyu Xiao
Measurements of the primordial element abundances provide us with an important probe of our universe's early thermal history, allowing us to constrain the expansion rate and compos…
Diffuse Ultra-High-Energy Gamma-Ray Emission From TeV Halos
Ariane Dekker, Ian Holst, Dan Hooper +3
The LHAASO Collaboration has recently reported a measurement of the diffuse gamma-ray emission from the Galactic Plane at energies between 10 TeV and 1 PeV. While this emission is…
Revisiting the proton synchrotron radiation in blazar jets: Possible contributions from X-ray to -ray bands
Rui Xue, Shao-Teng Huang, Hu-Bing Xiao +1
The proton synchrotron radiation is considered as the origin of high-energy emission of blazars at times. However, extreme physical parameters are often required. In this work, we…
Disruption of Dark Matter Minihaloes in the Milky Way environment: Implications for Axion Miniclusters and Early Matter Domination
Xuejian Shen, Huangyu Xiao, Philip F. Hopkins +1
Many theories of dark matter beyond the Weakly Interacting Massive Particles (WIMP) paradigm feature an enhanced matter power spectrum on sub-parsec scales, leading to the formatio…
Detecting Cosmic Strings with Lensed Fast Radio Bursts
Huangyu Xiao, Liang Dai, Matthew McQuinn
Correlated red noise recently reported from pulsar timing observations may be an indication of stochastic gravitational waves emitted by cosmic strings that formed during a primord…
SMBH Seeds from Dissipative Dark Matter
Huangyu Xiao, Xuejian Shen, Philip F. Hopkins +1
The existence of supermassive black holes (SMBHs) with masses greater than at high redshift () is difficult to accommodate in standard astrophysi…
Simulations of Axion Minihalos
Huangyu Xiao, Ian Williams, Matthew McQuinn
The axion, motivated as a solution to the strong CP problem, is also a viable dark matter candidate. We use N-body simulations to study the formation of substructures from white-no…
Early Structure Formation Constraints on the Ultra-Light Axion in the Post-Inflation Scenario
Vid Iršič, Huangyu Xiao, Matthew McQuinn
Many works have concentrated on the observable signatures of the dark matter being an ultralight axion-like particle (ALP). We concentrate on a particularly dramatic signature in t…
A Supersymmetric Theory of Baryogenesis and Sterile Sneutrino Dark Matter from Mesons
Gonzalo Alonso-Álvarez, Gilly Elor, Ann E. Nelson +1
Low-scale baryogenesis and dark matter generation can occur via the production of neutral mesons at MeV temperatures in the early Universe, which undergo CP-violating oscillati…
Baryogenesis from B Meson Oscillations
Ann E. Nelson, Huangyu Xiao
We show how CP violating B meson oscillations in conjunction with baryon number violating decays can generate the cosmological asymmetry between matter and anti-matter, and explore…
Axion Cosmology with Early Matter Domination
Ann E. Nelson, Huangyu Xiao
The default assumption of early universe cosmology is that the postinflationary universe was radiation dominated until it was about 47000 years old. Direct evidence for the radiati…
A Cosmic Selection Rule for Glueball Dark Matter Relic Density
Amarjit Soni, Huangyu Xiao, Yue Zhang
We point out a unique mechanism to produce the relic abundance for glueball dark matter from a gauged hidden sector which is bridged to the standard model sector through…
