Bubble in the Whale: Identifying the Optical Counterparts and Extended Nebula for the Ultraluminous X-ray Sources in NGC 4631
Jing Guo, Jianfeng Wu, Hua Feng +9
We present a deep optical imaging campaign on the starburst galaxy NGC 4631 with CFHT/MegaCam. By supplementing the HST/ACS and Chandra/ACIS archival data, we search for the optica…
Multiple gas phases in supernova remnant IC 443: mapping shocked H with VLT/KMOS
Yunwei Deng, Zhi-Yu Zhang, Ping Zhou +8
Supernovae and their remnants provide energetic feedback to the ambient interstellar medium (ISM), which is often distributed in multiple gas phases. Among them, warm molecular hyd…
Dependence of Chemical Abundance on the Cosmic Ray Ionization Rate in IC 348
Gan Luo, Zhi-Yu Zhang, Thomas G. Bisbas +8
Ions (e.g., H, HO) have been used extensively to quantify the cosmic-ray ionization rate (CRIR) in diffuse sightlines. However, measurements of CRIR in low-to-interme…
GeV Gamma-ray Emission and Molecular Clouds towards Supernova Remnant G35.60.4 and the TeV Source HESS J1858+020
Xiao Zhang, Yang Chen, Fa-xiang Zheng +3
It is difficult to distinguish hadronic process from the leptonic one in -ray observation, which is however crucial in revealing the origin of cosmic rays. As an endeavor in the…
Unusually high HCO+/CO ratios in and outside supernova remnant W49B
Ping Zhou, Gao-Yuan Zhang, Xin Zhou +10
Galactic supernova remnants (SNRs) and their environments provide the nearest laboratories to study SN feedback. We performed molecular observations toward SNR W49B, the most lumin…
