High-energy neutrino signatures of embedded GRB jets in AGN disks: a dynamic jet-propagation framework
Wei-Cheng Long, Yun-Wei Yu
Relativistic jets embedded in active galactic nucleus (AGN) accretion disks are promising high-energy neutrino sources, but their emission is often estimated from a single represen…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Mapping the Dense Circumstellar Environments of SNe Ibn, SNe Icn, and Fast Blue Optical Transients
Kang-Rui Ni, Yu-Hao Zhang, Liang-Duan Liu +2
SNe Ibn and SNe Icn are stripped-envelope explosions whose optical emission is commonly linked to interaction with H-poor circumstellar material (CSM), whereas fast blue optical tr…
GECAM Observations of the Galactic Magnetar SGR J1935+2154 during the 2021 and 2022 Burst Active Episodes. I. Burst Catalog
Sheng-Lun Xie, Ce Cai, Yun-Wei Yu +34
Magnetar is a neutron star with an ultrahigh magnetic field ( G). The magnetar SGR J1935+2154 is not only one of the most active magnetars detected so far, bu…
Revisit the periodicity of SGR J1935+2154 bursts with updated sample
Sheng-Lun Xie, Ce Cai, Shao-Lin Xiong +30
Since FRB 200428 has been found to be associated with an X-ray burst from the Galactic magnetar SGR J1935+2154, it is interesting to explore whether the magnetar bursts also follow…
A Target Search for Fast Radio Bursts Associated with Two Fast Blue Optical Transients: AT2018cow and CSS161010
Shi-Jie Gao, Xiang-Dong Li, Yi-Xuan Shao +5
Fast blue optical transients (FBOTs) are luminous, rapidly evolving events with blue spectra, possibly powered by newborn magnetars and linked to fast radio bursts (FRBs). Given th…
