Revealing a peculiar supernova remnant G106.3+2.7 as a petaelectronvolt proton accelerator with X-ray observations
Chong Ge, Ruo-Yu Liu, Shu Niu +2
Supernova remnants (SNRs) have long been considered as one of the most promising sources of Galactic cosmic rays. In the SNR paradigm, petaelectronvolt (PeV) proton acceleration ma…
Is PSR J08554644 responsible for the 1.4 TeV electron spectral bump hinted by DAMPE?
Yiwei Bao, Yang Chen, Siming Liu
DAMPE observation on the cosmic ray electron spectrum hints a narrow excess at 1.4 TeV. Although the excess can be ascribed to dark matter particles, pulsars and pulsar wind…
Modeling the broadest spectral band of the Crab nebula and constraining the ions acceleration efficiency
Xiao Zhang, Yang Chen, Jing Huang +1
Although it is widely accepted that the electromagnetic spectrum from radio to very-high-energy -rays of pulsar wind nebulae (PWNe) originates from leptons, there is still an op…
Molecular Clouds Surrounding Supernova Remnant G43.9+1.6: Associated and Non-associated
Xin Zhou, Yang Su, Ji Yang +4
Many supernova remnants (SNRs) are considered to evolve in molecular environments, but the associations between SNRs and molecular clouds (MCs) are often unclear. Being aware of su…
Chemical abundances in Sgr A East: evidence for a Type Iax supernova remnant
Ping Zhou, Shing-Chi Leung, Zhiyuan Li +3
Recent observations have shown a remarkable diversity of observational behaviors and explosion mechanisms in thermonuclear supernovae (SNe). An emerging class of peculiar thermonuc…
Revisiting the distance, environment and supernova properties of SNR G57.2+0.8 that hosts SGR 1935+2154
Ping Zhou, Xin Zhou, Yang Chen +3
We have performed a multi-wavelength study of supernova remnant (SNR) G57.2+0.8 and its environment. The SNR hosts the magnetar SGR 1935+2154, which emitted an extremely bright ms-…
An XMM-Newton X-ray View of Supernova Remnant W49B: Revisiting its Recombining Plasmas and Progenitor Type
Lei Sun, Yang Chen
We present a comprehensive X-ray spectroscopy and imaging study of supernova remnant W49B using archival XMM-Newton observations. The overionization state of the shocked ejecta in…
A Small-Scale Investigation of Molecular Emission toward the Tip of the Western Lobe of W50/SS433
Qian-Cheng Liu, Yang Chen, Ping Zhou +2
We perform a molecular (CO and CN) line observation using IRAM 30m telescope toward two small regions near the western edge of supernova remnant (SNR) W50/SS433. CO observation rev…
