Dust Absorption towards Supernova Remnant W44
Tian-Yu Tu, Adwin Boogert, Yang Chen +1
Supernova remnants (SNRs) can strongly affect the chemical composition of the interstellar dust. In this paper we investigate to what degree the dust and ices are modified by obser…
SGR 1935+2154's Quiet Local Environment: Clues for Its Progenitor
Wenlang He, Ping Zhou, Bingqiu Chen
Magnetars are highly magnetized neutron stars (NSs) whose evolution and radiation are governed by the decay and/or reconfiguration of their magnetic fields. The origin of magnetars…
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…
X-ray polarization in SN 1006 southwest shows spatial variations and differences with the radio band
Ping Zhou, Patrick Slane, Dmitry Prokhorov +15
We report the detection of a spatial variation of X-ray polarization in the southwestern shell of SN 1006 (SN 1006 SW) using IXPE. The shell has an average X-ray polarization degre…
