Multiband optical flux density and polarization microvariability study of optically bright blazars
Magdalena Pasierb, Arti Goyal, Michał Ostrowski +21
We present the results of flux density, spectral index, and polarization intra-night monitoring studies of a sample of eight optically bright blazars, carried out by employing seve…
Near-infrared Monitoring of the Accretion Outburst in the MYSO S255-NIRS3
Mizuho Uchiyama, Takuya Yamashita, Koichiro Sugiyama +10
We followed-up the massive young stellar object (MYSO) S255-NIRS3 (=S255-IRS1b) during its recent accretion outburst event in the Ks band with Kanata/HONIR for four years after its…
SN 2018hna: 1987A-like supernova with a signature of shock breakout
Avinash Singh, D. K. Sahu, G. C. Anupama +22
High cadence ultraviolet, optical and near-infrared photometric and low-resolution spectroscopic observations of the peculiar Type II supernova (SN) 2018hna are presented. The earl…
Type Ia SN 2019ein: New Insights into the Similarities and diversities among High-Velocity SNe Ia
Miho Kawabata, Keiichi Maeda, Masayuki Yamanaka +38
We present optical observations of type Ia supernova (SN) 2019ein, starting at 2 days after the estimated explosion date. The spectra and the light curves show that SN 2019ein belo…
On the observational behaviour of the highly polarized Type IIn supernova SN 2017hcc
Brajesh Kumar, Chakali Eswaraiah, Avinash Singh +10
We present the results based on photometric ( UVOT), broad-band polarimetric ( and -band) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc…
