Primordial Black Hole Interpretation in Subsolar Mass Gravitational Wave Candidate SSM200308
Chen Yuan, Qing-Guo Huang
In the recent second part of the third observation run by the LIGO-Virgo-KAGRA collaboration, a candidate with sub-solar mass components was reported, which we labelled as SSM20030…
Full analysis of the scalar-induced gravitational waves for the curvature perturbation with local-type non-Gaussianities
Chen Yuan, De-Shuang Meng, Qing-Guo Huang
Primordial black holes (PBHs) are supposed to form through the gravitational collapse of regions with large density fluctuations. The formation of PBHs inevitably leads to the emis…
Primordial black holes generated by the non-minimal spectator field
De-Shuang Meng, Chen Yuan, Qing-Guo Huang
In this paper, we propose a model in which a spectator field non-minimally couples to an inflaton field and the power spectrum of the perturbation of the spectator field at small s…
One-loop correction to the enhanced curvature perturbation with local-type non-Gaussianity for the formation of primordial black holes
De-Shuang Meng, Chen Yuan, Qing-guo Huang
As one of the promising candidates of cold dark matter (DM), primordial black holes (PBHs) were formed due to the collapse of over-densed regions generated by the enhanced curvatur…
GeV Signatures of Short Gamma-Ray Bursts in Active Galactic Nuclei
Chengchao Yuan, Kohta Murase, Dafne Guetta +3
The joint detection of gravitational waves and the gamma-ray counterpart of a binary neutron star merger event, GW170817, unambiguously validates the connection between short gamma…
Near-horizon microstructure and superradiant instability of black holes
Rong-Zhen Guo, Chen Yuan, Qing-Guo Huang
Ultralight bosons, as important candidates of dark matter, can condense around spinning black holes (BHs) to form long-lived ``boson clouds'' due to superradiance instability. The…
Confronting the primordial black hole scenario with the gravitational-wave events detected by LIGO-Virgo
Zu-Cheng Chen, Chen Yuan, Qing-Guo Huang
Adopting a binned method, we model-independently reconstruct the mass function of primordial black holes (PBHs) from GWTC-3 and find that such a PBH mass function can be explained…
A topic review on probing primordial black hole dark matter with scalar induced gravitational waves
Chen Yuan, Qing-Guo Huang
Primordial black holes (PBHs) are supposed to form from the collapse of over-densed regions generated by large scalar curvature perturbations in the radiation dominated era. Despit…
External Inverse-Compton Emission Associated with Extended and Plateau Emission of Short Gamma-Ray Bursts: Application to GRB 160821B
B. Theodore Zhang, Kohta Murase, Chengchao Yuan +2
The recent detection of TeV photons from two gamma-ray bursts (GRBs), GRB 190114C and GRB 180720B, has opened a new window for multi-messenger and multi-wavelength astrophysics of…
Non-tensorial Gravitational Wave Background in NANOGrav 12.5-Year Data Set
Zu-Cheng Chen, Chen Yuan, Qing-Guo Huang
We perform the first search for an isotropic non-tensorial gravitational-wave background (GWB) allowed in general metric theories of gravity in the North American Nanohertz Observa…
Post-Merger Jets from Supermassive Black Hole Coalescences as Electromagnetic Counterparts of Gravitational Wave Emission
Chengchao Yuan, Kohta Murase, B. Theodore Zhang +2
As a powerful source of gravitational waves (GW), a supermassive black hole (SMBH) merger may be accompanied by a relativistic jet that leads to detectable electromagnetic (EM) emi…
High-energy neutrino emission subsequent to gravitational wave radiation from supermassive black hole mergers
Chengchao Yuan, Kohta Murase, Shigeo S. Kimura +1
Supermassive black hole (SMBH) coalescences are ubiquitous in the history of the Universe and often exhibit strong accretion activities and powerful jets. These SMBH mergers are al…

In this letter we calculate the scalar induced gravitational waves (SIGWs) accompanying the formation of primordial black hole during the radiation dominated era in three different…
Pulsar Timing Array Constraints on Primordial Black Holes with NANOGrav 11-Year Data Set
Zu-Cheng Chen, Chen Yuan, Qing-Guo Huang
The detection of binary black hole coalescences by LIGO/Virgo has aroused the interest in primordial black holes (PBHs), because they could be both the progenitors of these black h…
Log-dependent slope of scalar induced gravitational waves in the infrared regions
