Evolution of X-ray Gas in SN 1987A from 2007 to 2021: Ring Fading and Ejecta Brightening Unveiled through Differential Emission Measure Analysis
Lei Sun, Salvatore Orlando, Emanuele Greco +4
As the nearest supernova (SN) observed since Kepler's SN of 1604, SN 1987A provides an unprecedented opportunity to study in detail the early evolution of supernova remnants (SNRs)…
Unusual X-ray Oxygen Line Ratios of SN 1987A Arising From the Absorption of Galactic Hot Interstellar Medium
Lei Sun, Salvatore Orlando, Emanuele Greco +5
Recent high-resolution X-ray spectroscopic studies have revealed unusual oxygen line ratios, such as the high O VII forbidden-to-resonance ratio, in several supernova remnants. Whi…
An X-ray Shell Reveals the Supernova Explosion for Galactic Microquasar SS 433
Yi-Heng Chi, Jiahui Huang, Ping Zhou +5
How black holes are formed remains an open and fundamental question in Astrophysics. Despite theoretical predictions, it lacks observations to understand whether the black hole for…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
Optical observations of the Galactic SNR HB9 and H II region G159.2+3.3
Jiang-Tao Li, Li-Yuan Lu, Huiyang Mao +4
Context. We present multi-wavelength observations of the Galactic SNR HB9 and the H II region G159.2+3.3 apparently projected nearby, in order to study their properties and potenti…
Thermal X-ray Emission in the Western Half of the LMC Superbubble 30 Dor C
Yi-Heng Chi, Han-Xiao Chen, Yang Chen +4
While 30 Dor C is a unique superbubble in the Large Magellanic Cloud for its luminous non-thermal X-ray emission, the thermal X-ray emission it emanates has not yet been thoroughly…
