Constraining the Charge of a Black Hole with Electromagnetic Radiation from a Black Hole-Neutron Star System
Hao-Yu Yuan, Hou-Jun Lü, Jared Rice +1
Black hole-neutron star (BH-NS) mergers are expected to emit gravitational-wave (GW) and electromagnetic (EM) counterparts when the NS is tidally disrupted or plunges into the BH.…
Diagnosing the remnants of binary neutron star merger from GW170817/GRB170817A event
Hou-Jun Lü, Jun Shen, Lin Lan +3
The event GW170817/GRB 170817A, discovered via the successful joint observation of its gravitational wave radiation and its multi-wavelength electromagnetic counterparts, was the f…
Gravitational-wave evolution of newborn magnetars with different deformed structure
Jun-Xiang Huang, Hou-Jun Lü, Jared Rice +1
Weak and continuous gravitational-wave (GW) radiation can be produced by newborn magnetars with deformed structure and is expected to be detected by the Einstein telescope in the n…
Signature of a magnetar central engine with precession motion in the X-ray emission of GRB 220711B
Ying-Ze Shan, Xing Yang, Hou-Jun Lü +6
The -ray light curve of long-duration GRB 220711B, is characterized by a multi-peaked structure with a duration lasting 105 seconds. More interestingly, the X-ray aftergl…
Discovery of high-frequency quasi-periodic oscillation in short-duration gamma-ray bursts
Xing Yang, Hou-Jun Lü, Jared Rice +1
Rapidly rotating newborn magnetars, which originate from binary neutron star (NS) mergers and serve as the central engines of short gamma-ray bursts (GRBs), may leave some imprints…
Ejecta-circumstellar medium interaction in high-density environment contribution to kilonova emission: Application to GRB 191019A
Suo-Ning Wang, Hou-Jun Lü, Yong Yuan +4
The nearby long-duration GRB 191019A recently detected by Swift lacks an associated supernova and belongs to a host galaxy with little star formation activity, suggesting that the…
Magnetar central engine and possible gravitational wave emission of nearby short GRB 160821B
Hou-Jun Lü, Hai-Ming Zhang, Shu-Qing Zhong +4
GRB 160821B is a short gamma-ray burst (GRB) at redshift , with a duration less than 1 second and without detection of any "extended emission" up to more than 100 seconds i…
Constraining the nuclear equation of state via gravitational-wave radiation of short gamma-ray burst remnants
Lin Lan, Hou-Jun Lü, Jared Rice +1
The observed internal plateau of X-ray emission in some short GRBs suggests the formation of a remnant supra-massive magnetar following a double neutron star (NS) merger. In this p…
Astro2020 APC White Paper: The Early Career Perspective on the Coming Decade, Astrophysics Career Paths, and the Decadal Survey Process
Emily Moravec, Ian Czekala, Kate Follette +53
In response to the need for the Astro2020 Decadal Survey to explicitly engage early career astronomers, the National Academies of Sciences, Engineering, and Medicine hosted the Ear…
The properties of prompt emission in short GRBs with extended emission observed by {\em Fermi}/GBM
Lin Lan, Rui-Jing Lu, Hou-Jun Lü +4
Short GRBs with extended emission (EE) that are composed initially of a short-hard spike and followed by a long-lasting EE, are thought to be classified as a subsection of short GR…
Characteristics of Two-episode Emission Patterns in {\em Fermi} Long Gamma-Ray Bursts
Lin Lan, Hou-Jun Lü, Shu-Qing Zhong +8
Two-episode emission components separated by quiescent gaps in the prompt emission of gamma-ray bursts (GRBs) have been observed in the {\em Swift} era, but there is a lack of spec…
Spin, inclination, and magnetic field evolution of magnetar population in vacuum and plasma-filled magnetospheres
Jun-Xiang Huang, Hou-Jun Lü, Jared Rice +1
Magnetars are potential energy sources or central engines for numerous transient phenomena in the Universe. How newborn magnetars evolve in different environments remains an open q…
Evidence for gravitational lensing of GRB 200716C
Xing Yang, Hou-Jun Lü, Hao-Yu Yuan +4
Observationally, there is a small fraction of Gamma-ray bursts (GRBs) with prompt emission observed by Fermi/GBM that are composed of two pulses. Occasionally, the distance to a GR…
GRB 211227A as a peculiar long gamma-ray burst from compact star merger
Hou-Jun Lü, Hao-Yu Yuan, Ting-Feng Yi +16
Long-duration gamma-ray bursts (GRBs) associated with supernovae (SNe) are believed to originate from massive star core-collapse events, whereas short-duration GRBs that are relate…
