Alien Type Ia supernovae from the Milky Way merger history and one possible candidate: Kepler's supernova
Wenlang He, Ping Zhou, Eda Gjergo +1
The Milky Way is a dynamic and evolving system shaped by numerous merger events throughout its history. These mergers bring stars with kinematic and dynamic properties differing fr…
ASKAP observations of the radio shell in the composite supernova remnant G310.6-1.6
Wenhui Jing, Jennifer L. West, Xiaohui Sun +12
We report the observations of the radio shell of the supernova remnant (SNR) G310.6-1.6 at 943 MHz from the Evolutionary Map of the Universe (EMU) and the Polarization Sky Survey o…
Broadband -ray spectrum of supernova remnant Cassiopeia A
Zhen Cao, F. Aharonian, Y. X. Bai +311
The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of 2.5 $\arcmin$. Although no extension…
Discovery of a millisecond pulsar associated with Terzan 6
Shi-Jie Gao, Yi-Xuan Shao, Pei Wang +6
Observations show that globular clusters might be among the best places to find millisecond pulsars. However, the globular cluster Terzan 6 seems to be an exception without any pul…
GTC optical/NIR upper limits and NICER X-ray analysis of SGR J1935+2154 for the outburst in 2022
Yi-Xuan Shao, Ping Zhou, Xiang-Dong Li +8
The Galactic magnetar SGR J1935+2154 has undergone another outburst since 2022 October 10. We present the results of searching for an optical/NIR counterpart of SGR J1935+2154 befo…
