Formation of Fast-spinning Neutron Stars in Close Binaries and Magnetar-driven Stripped-envelope Supernovae
Rui-Chong Hu, Jin-Ping Zhu, Ying Qin +8
Extreme stripped-envelope supernovae (SESNe), including Type Ic superluminous supernovae (SLSNe-I), broad-line Type Ic SNe (SNe Ic-BL), and fast blue optical transients (FBOTs), ar…
Searching for candidates of coalescing binary black holes formed through chemically homogeneous evolution in GWTC-3
Ying Qin, Yuan-Zhu Wang, Simone S. Bavera +10
The LIGO, Virgo, and KAGRA (LVK) collaboration has announced 90 coalescing binary black holes (BBHs) with to date, however, the origin of their formation cha…
A possible 250-second X-ray quasi-periodicity in the fast blue optical transient AT2018cow
Wenjie Zhang, Xinwen Shu, Jin-Hong Chen +11
The fast blue optical transients (FBOTs) are a new population of extragalactic transients of unclear physical origin. A variety of mechanisms have been proposed including failed su…
Potential Subpopulations and Assembling Tendency of the Merging Black Holes
Yuan-Zhu Wang, Yin-Jie Li, Jorick S. Vink +4
The origins of coalescing binary black holes (BBHs) detected by the advanced LIGO/Virgo are still under debate, and clues may be present in the joint mass-spin distribution of thes…
Long-duration Gamma-ray Burst and Associated Kilonova Emission from Fast-spinning Black Hole--Neutron Star Mergers
Jin-Ping Zhu, Xiangyu Ivy Wang, Hui Sun +5
Here we collect three unique bursts, GRBs\,060614, 211211A and 211227A, all characterized by a long-duration main emission (ME) phase and a rebrightening extended emission (EE) pha…
Hypercritical Accretion for Black Hole High Spin in Cygnus X-1
Ying Qin, Xinwen Shu, Shuangxi Yi +1
Recent observations of AdLIGO and Virgo have shown that the spin measurements in binary black hole (BH) systems are typically small, which is consistent with the predictions by the…
A Channel to Form Fast-spinning Black Hole--Neutron Star Binary Mergers as Multi-messenger Sources
Rui-Chong Hu, Jin-Ping Zhu, Ying Qin +3
After the successful detection of a gravitational-wave (GW) signal and its associated electromagnetic (EM) counterparts from GW170817, neutron star--black hole (NSBH) mergers have…
Population Properties of Gravitational-Wave Neutron Star--Black Hole Mergers
Jin-Ping Zhu, Shichao Wu, Ying Qin +3
Over the course of the third observing run of LIGO-Virgo-KAGRA Collaboration, several gravitational-wave (GW) neutron star--black hole (NSBH) candidates have been announced. By ass…
Constraining the circumburst medium of gamma-ray bursts with X-ray afterglows
Xiao Tian, Ying Qin, Mei Du +2
Long gamma-ray bursts (GRBs) are considered to be originated from core collapse of massive stars. It is believed that the afterglow property is determined by the density of the mat…
Mass and effective spin distributions of binary black hole events: Evidence for a population of hierarchical black hole mergers in active galactic nuclei disks
Yuan-Zhu Wang, Yi-Zhong Fan, Shao-Peng Tang +2
The origins of the coalescing binary black holes (BBHs) detected by the advanced LIGO/Virgo are still in debate and clues may present in the mass and effective spin ()…
On the Angular Momentum Transport Efficiency within the Star Constrained from Gravitational-wave Observations
Ying Qin, Yuan-Zhu Wang, Dong-Hong Wu +2
The LIGO Scientific Collaboration and Virgo Collaboration (LVC) have recently reported in GWTC-2.1 eight additional candidate events with a probability of astrophysical origin grea…
Probing the progenitors of spinning binary black-hole mergers with long gamma-ray bursts
Simone S. Bavera, Tassos Fragos, Emmanouil Zapartas +15
Long-duration gamma-ray bursts are thought to be associated with the core-collapse of massive, rapidly spinning stars and the formation of black holes. However, efficient angular m…
The role of core-collapse physics in the observability of black-hole neutron-star mergers as multi-messenger sources
Jaime Román-Garza, Simone S. Bavera, Tassos Fragos +10
Recent detailed 1D core-collapse simulations have brought new insights on the final fate of massive stars, which are in contrast to commonly used parametric prescriptions. In this…
