A Magnetar Engine and Circumstellar Medium Interaction: Synergistic Effects in Producing Superluminous Supernovae
Guang-Lei Wu, Yun-Wei Yu, Liang-Duan Liu
Superluminous supernovae (SLSNe) are often modeled as being powered either by a central engine or by strong interaction with dense circumstellar material (CSM). These two mechanism…
Spectral Evidence of Heavy Nuclei from the Neutron Star Crust in Magnetar Bursts
Sheng-Lun Xie, Yun-Wei Yu, Shao-Lin Xiong +1
The crust of a neutron star (NS) provides a unique laboratory for studying matter under extreme density and magnetic field conditions that cannot be realized in terrestrial experim…
The Dust Echo Emission of Fast Blue Optical Transients and Application to the Near-Infrared Excess of AT 2018cow
Jing-Yao Li, Yun-Wei Yu, Liang-Duan Liu +1
A near-infrared (NIR) excess has been discovered in the emission of the representative fast blue optical transient (FBOT): AT 2018cow. It was suggested that this NIR excess could b…
EP241021a: A catastrophic collapse/merger of compact star binary leading to the formation of a remnant millisecond magnetar?
Guang-Lei Wu, Yun-Wei Yu, Liang-Duan Liu +7
Observations of fast X-ray transients (FXRTs) with the Einstein Probe have successfully led to the discovery of some unusual extragalactic optical transients. EP241021a is a newly…
Measurement of Neutral Atmosphere Density During the Years of Increasing Solar Activity Using \textit{Insight}-HXMT Data with the Earth Occultation Technique
Hao-Hui Zhang, Wang-Chen Xue, Xiao-Bo Li +8
The density of the Earth's middle and upper atmosphere is an important question in Earth science and is a critical factor in the design, operation, and orbital determination of low…
Propagation of GRB Relativistic Jets in AGN Disks and Its Implication for GRB Detection
Hao-Hui Zhang, Jin-Ping Zhu, Yun-Wei Yu
The accretion disks of supermassive black holes (SMBHs) harboring in active galactic nuclei (AGN) are considered to be an ideal site for producing different types of gamma-ray burs…
