XMM-Newton Resolves Parsec-scale X-ray Jets in the PeVatron Microquasar V4641 Sgr
Naomi Tsuji, Caterina Tresoldi, Kaya Mori +34
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of deg…
Candidate X-ray Counterparts of Ultra-High-Energy Emission of the Galactic Microquasar V4641 Sgr Revealed by Einstein Probe
Yi-Heng Chi, Shao-Qiang Xi, Ping Zhou +20
Microquasars have emerged as promising PeVatron candidates capable of accelerating particles to PeV energies, with recent observations revealing ultra-high-energy (UHE) -ray emi…
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…
Molecular chemistry induced by J-shock toward supernova remnant W51C
Tian-Yu Tu, Valentine Wakelam, Yang Chen +2
Shock waves from supernova remnants (SNRs) have strong influence on the physical and chemical properties of molecular clouds (MCs). Shocks propagating into magnetized MCs can be cl…
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…
Shock and Cosmic Ray Chemistry Associated with the Supernova Remnant W28
Tian-Yu Tu, Yang Chen, Ping Zhou +1
Supernova remnants (SNRs) exert strong influence on the physics and chemistry of the nearby molecular clouds (MCs) through shock waves and the cosmic rays (CRs) they accelerate. To…
Upper Limits of Ti Decay Emission in Four Nearby Thermonuclear Supernova Remnants
Jianbin Weng, Ping Zhou, Hagai B. Perets +2
To identify progenitors and investigate evidence of He burning, we searched for decay radiation of freshly synthesized Ti in four young nearby thermonuclear supernova remnan…
Upper limits on the radio pulses from magnetars and a central compact object with FAST
Wan-Jin Lu, Ping Zhou, Pei Wang +5
Magnetars and central compact objects (CCOs) are subgroups of neutron stars that show a number of properties distinguished from canonical radio pulsars. We performed radio observat…
Discovery and timing of pulsar J20163711 in supernova remnant CTB 87 with FAST
Qian-Cheng Liu, Wen-Juan Zhong, Yang Chen +4
We report on our discovery of the radio pulsar, PSR J20163711, in supernova remnant (SNR) CTB 87, with a significance of pulses, which confirms the compact nature of…
