Phosphorus in the Young Supernova Remnant Cassiopeia A
Bon-Chul Koo, Yong-Hyun Lee, Dae-Sik Moon +2
Phosphorus (P), which is essential for life, is thought to be synthesized in massive stars and dispersed into interstellar space when these stars explode as supernovae (SNe)…
Hi Shells and Supershells in the I-GALFA Hi 21-cm Line Survey: I. Fast-Expanding Hi Shells Associated with Supernova Remnants
Geumsook Park, Bon-Chul Koo, Steven J. Gibson +7
We search for fast-expanding Hi shells associated with Galactic supernova remnants (SNRs) in the longitude range l \approx 32\arcdeg to 77\arcdeg using 21-cm line data from the Inn…
Near-Infrared Spectroscopy of Infrared-Excess Stellar Objects in the Young Supernova Remnant G54.1+0.3
Hyun-Jeong Kim, Bon-Chul Koo, Dae-Sik Moon
We present the results of broadband near-infrared spectroscopic observations of the recently discovered mysterious stellar objects in the young supernova remnant G54.1+0.3. These o…
Wide Integral-Field Infrared Spectroscopy of the Bright [Fe II] Shell in the Young Supernova Remnant G11.2-0.3
Ho-Gyu Lee, Dae-Sik Moon, Bon-Chul Koo +9
We present the results of wide integral-field near-infrared (1.0-1.8 um) spectroscopic observations of the southeastern shell of the young core-collapse supernova remnant (SNR) G11…
Infrared [Fe II] and Dust Emissions from Supernova Remnants
Bon-Chul Koo
Supernova remnants (SNRs) are strong thermal emitters of infrared radiation. The most prominent lines in the near-infrared spectra of SNRs are [Fe II] lines. The [Fe II] lines are…
