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…
Simulation of proton radiolysis of H2O and O2 ices with the Nautilus code
Tian-Yu Tu, Valentine Wakelam, Jean-Christophe Loison +3
The radiolysis effect of cosmic rays (CRs) plays an important role in the chemistry in molecular clouds. CRs can dissociate the molecules on dust grains, producing reactive suprath…
CO =3--2 Observations of Tycho's supernova remnant: constraints on the environmental gas properties
Sendi Bo, Yu Huang, Ping Zhou +5
Recent observations suggest that Tycho's supernova remnant (SNR; SN 1572) is expanding into a cavity wall of molecular clouds (MCs), which decelerate the SNR and influence its mult…
Absence of Radio Emission Reveals an Exceptionally Weak Explosion of the Putative Historical Supernova Pa 30
Yi-xuan Shao, Ping Zhou, Xiao Zhang +7
We present the first deep radio continuum observations of Pa 30, a nebula hosting a unique optical source driven by an ultrafast outflow with a velocity of 16,000 km s. The…
GeV Gamma-Rays from Molecular Clouds Illuminated by Particles Diffusing from the Adjacent Supernova Remnant G335.2+0.1 Confined in an Expanding Bubble
Chen Huang, Xiao Zhang, Yang Chen +3
We report the detection of GeV gamma-ray emission likely associated with supernova remnant (SNR) G335.2+0.1 and the finding of a molecular cloud (-- in angular s…
Expanding Molecular Shell and Possible γ-ray Source Associated with Supernova Remnant Kesteven 67
Yun-Zhi Shen, Yang Chen, Xiao Zhang +4
We investigate the molecular environment of the supernova remnant (SNR) Kesteven 67 (G18.8+0.3) using observations in CO, CO, HCO,and HCN lines and possible assoc…
