Near-Infrared and Optical Observations of Type Ic SN 2021krf: Luminous Late-time Emission and Dust Formation
Aravind P. Ravi, Jeonghee Rho, Sangwook Park +29
We present near-infrared (NIR) and optical observations of the Type Ic supernova (SN Ic) SN 2021krf obtained between days 13 and 259 at several ground-based telescopes. The NIR spe…
A survey of infrared supernova remnants in the Large Magellanic Cloud
Ji Yeon Seok, Bon-Chul Koo, Takashi Onaka
We present a comprehensive infrared study of supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) using near- to mid-infrared images taken by Infrared Array Camera (IRAC;…
Detection of 3.3 Micron Aromatic Feature in the Supernova Remnant N49 with AKARI
Ji Yeon Seok, Bon-Chul Koo, Takashi Onaka
We present an infrared study of the supernova remnant (SNR) N49 in the Large Magellanic Cloud with the near-infrared (NIR; 2.5 - 5 μm) spectroscopic observations performed by AKARI…
Dense Iron Ejecta and Core-collapse Supernova Explosion in the Young Supernova Remnant G11.2-0.3
Dae-Sik Moon, Bon-Chul Koo, Ho-Gyu Lee +5
We present the results of near-infrared spectroscopic observations of dense ($\simgt$ 10 cm) iron ejecta in the young core-collapse supernova remnant G11.2-0.3. Five eje…
