SN 2020jfo: A short plateau Type II supernova from a low mass progenitor
Rishabh Singh Teja, Avinash Singh, D. K. Sahu +3
We present spectroscopic and photometric observations of the Type IIP supernova, SN 2020jfo, in ultraviolet and optical wavelengths. SN 2020jfo occurred in the spiral galaxy M61 (N…
Investigating the observational properties of Type Ib supernova SN 2017iro
Brajesh Kumar, Avinash Singh, D. K. Sahu +1
We report results of optical imaging and low-resolution spectroscopic monitoring of supernova (SN) 2017iro that occurred in the nearby (\,31 Mpc) galaxy NGC 5480. The \ion{He…
Enhancement in Thermally Generated Spin Voltage at Pd/NiFeO Interfaces by the Growth on Lattice-Matched Substrates
A. Rastogi, Z. Li, A. V. Singh +15
Efficient spin injection from epitaxial ferrimagnetic NiFeO thin films into a Pd layer is demonstrated via spin Seebeck effect measurements in the longitudinal geometry. Th…
Flash ionization signatures in the type Ibn supernova SN 2019uo
Anjasha Gangopadhyay, Kuntal Misra, Daichi Hiramatsu +26
We present photometric and spectroscopic observations of the type Ibn supernova (SN) 2019uo, the second ever SN Ibn with flash ionization (He II, C III, N III) features in its earl…
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…
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…
