Supernova Remnants in the AKARI IRC Survey of the Large Magellanic Cloud
Ji Yeon Seok, Bon-Chul Koo, Takashi Onaka +9
We present the near- to mid-infared study of supernova remnants (SNRs) using the AKARI IRC Survey of the Large Magellanic Cloud (LMC). The LMC survey observed about a 10 square deg…
Near-Infrared [Fe II] and H2 Line Observations of the Supernova Remnant 3C 396: Probing the Pre-supernova Circumstellar Materials
Ho-Gyu Lee, Dae-Sik Moon, Bon-Chul Koo +2
We present the results of near-infrared [Fe II] and H2 line imaging and spectroscopic observations of the supernova remnant 3C 396 using the Palomar 5 m Hale telescope. We detect l…
Massive-Star Forming Infrared Loop around the Crab-like Supernova Remnant G54.1+0.3: Post Main-Sequence Triggered Star Formation?
Bon-Chul Koo, Christopher F. McKee, Jae-Joon Lee +6
We report the discovery of a star-forming loop around the young, Crab-like supernova remnant (SNR) G54.1+0.3 using the AKARI infrared satellite. The loop consists of at least eleve…
SUBARU HDS Observations of a Balmer-Dominated Shock in Tycho's Supernova Remnant
Jae-Joon Lee, Bon-Chul Koo, John Raymond +4
We present an Ha spectral observation of a Balmer-dominated shock on the eastern side of Tycho's supernova remnant using the Subaru Telescope. Utilizing the High Dispersion Spectro…
AKARI Detection of the Infrared-Bright Supernova Remnant B0104-72.3 in the Small Magellanic Cloud
Bon-Chul Koo, Ho-Gyu Lee, Dae-Sik Moon +12
We present a serendipitous detection of the infrared-bright supernova remnant (SNR) B0104-72.3 in the Small Magellanic Cloud by the Infrared Camera (IRC) onboard AKARI. An elongate…
[Fe II] and H2 filaments in the Supernova Remnant G11.2-0.3: Supernova Ejecta and Presupernova Circumstellar Wind
Bon-Chul Koo, Dae-Sik Moon, Ho-Gyu Lee +2
We present the results of near-infrared imaging and spectroscopic observations of the young, core-collapse supernova remnant (SNR) G11.2-0.3. In the [Fe II] 1.644 um image, we firs…
