The nanohertz stochastic gravitational wave background from cosmic string loops and the abundant high redshift massive galaxies
Ziwei Wang, Lei Lei, Hao Jiao +2
Recently, pulsar timing array (PTA) experiments have provided compelling evidence for the existence of the nanohertz stochastic gravitational wave background (SGWB). In this work,…
Primordial magnetic field as a common solution of nanohertz gravitational waves and the Hubble tension
Yao-Yu Li, Chi Zhang, Ziwei Wang +4
The origin of interstellar and intergalactic magnetic fields remains largely unknown. One possibility is that they are related to the primordial magnetic fields (PMFs) produced by,…
Mirror QCD phase transition as the origin of the nanohertz Stochastic Gravitational-Wave Background
Lei Zu, Chi Zhang, Yao-Yu Li +3
Several Pulsar Timing Array (PTA) collaborations have recently provided strong evidence for a nHz Stochastic Gravitational-Wave Background (SGWB). Here we investigate the implicati…
R-process beta-decay neutrino flux from binary neutron star mergers and collapsars
Yu An, Meng-Ru Wu, Gang Guo +3
This study investigates the antineutrinos production by -decay of -process nuclei in two astrophysical sites that are capable of producing gamma-ray bursts (GRBs): binary neu…
Constraining ultralight dark matter using the Fermi-LAT pulsar timing array
Zi-Qing Xia, Tian-Peng Tang, Xiaoyuan Huang +2
Ultralight dark matter (ULDM) is proposed as a theoretical candidate of dark matter particles with masses of approximately eV. The interactions between ULDM particles an…
SKA sensitivity for possible radio emission from dark matter in Omega Centauri
Guan-Sen Wang, Zhan-Fang Chen, Lei Zu +3
Omega Centauri, the largest known globular cluster in the Milky Way, is believed to be the remains of a dwarf galaxy's core. Giving its potential abundance of dark matter (DM), it…
Multi-frequency test of dark matter annihilation into long-lived particles in Sirius
Yu-Xuan Chen, Lei Zu, Zi-Qing Xia +2
New long-lived particles produced at the colliders may escape from conventional particle detectors. Using satellites or ground telescopes, we can detect the photons generated from…
Constraining ultralight bosonic dark matter with Keck observations of S2's orbit and kinematics
Guan-Wen Yuan, Zhao-Qiang Shen, Yue-Lin Sming Tsai +2
Ultralight bosonic dark matter is expected to be able to form a cloud surrounding the supermassive black hole (SMBH) in the Galactic center. With increasing precision of the observ…
Explaining the GeV antiproton/ray excesses and W-boson mass anomaly in an inert two Higgs doublet model
Cheng-Rui Zhu, Ming-Yang Cui, Zi-Qing Xia +4
For the newly discovered -boson mass anomaly, one of the simplest dark matter (DM) models that can account for the anomaly without violating other astrophysical/experimental con…
Muonphilic Dark Matter explanation of gamma-ray galactic center excess: a comprehensive analysis
Murat Abdughani, Yi-Zhong Fan, Chih-Ting Lu +2
The Galactic center gamma-ray excess (GCE) is a long-standing unsolved problem. One of candidate solutions, the dark matter (DM) annihilation, has been recently tested with other a…
Constraining Asymmetric Bosonic Non-interacting Dark Matter with Neutron Stars
Yi-zhong Fan, Rui-zhi Yang, Jin Chang
The Hawking evaporation of small black holes formed by the collapse of dark matter at the center of neutron stars plays a key role in loosing the constraint on the mass of asymmetr…
Excesses in the Cosmic Ray Spectrum and Possible Interpretations
Yi-Zhong Fan, Bing Zhang, Jin Chang
The data collected by ATIC, PPB-BETS, FERMI-LAT and HESS all indicate that there is an electron/positron excess in the cosmic ray energy spectrum above 100 GeV, although dif…
