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…
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…
Mapping the dense molecular gas towards thirteen supernova remnants
Tian-Yu Tu, Yang Chen, Qian-Cheng Liu
Supernova remnants (SNRs) can exert strong influence on molecular clouds (MCs) through interaction by shock wave and cosmic rays. In this paper, we present our mapping observation…
