Wild behaviour near the finish line: the Type Ibn SN 2020able and its stratified environment
L. Tartaglia, E. Cappellaro, G. Valerin +29
We present spectrophotometric observations of the Type Ibn supernova SN~2020able, along with a comprehensive analysis and modelling of its evolution. The transient occurred in SDSS…
An Afterglow Study of the "New Year's Burst" GRB 220101A
Agniva Roychowdhury, Tuomas Kangas, Andrew Fruchter +12
We present a detailed broadband afterglow study of GRB 220101A ( s) combining multi-wavelength data from soft X-rays until 6 GHz. The afterglow light c…
SN 2021tsz: A luminous, short photospheric phase Type II supernova in a low-metallicity host
R. Dastidar, G. Pignata, N. Dukiya +14
We present the analysis of the luminous Type II Supernova (SN) 2021tsz, which exploded in a low-luminosity galaxy. It reached a peak magnitude of -18.88 0.13 mag in the b…
SN 2018is: a low-luminosity Type IIP supernova with narrow hydrogen emission lines at early phases
R. Dastidar, K. Misra, S. Valenti +31
We present a comprehensive photometric and spectroscopic study of the Type IIP SN 2018is. The -band luminosity and the expansion velocity at 50 days post-explosion are 15.1$\…
