Optical observations of supernova candidates with the ILMT
Monalisa Dubey, Bhavya Ailawadhi, Talat Akhunov +10
The International Liquid Mirror Telescope (ILMT) is a 4-m optical ({\em gri} spectral bands) zenithal survey telescope with a field of view of 22.322.3 arcmin, suitable for…
Early NIR echo and the time variable mass loss history of Type IIn SN 2024kgi
Naveen Dukiya, Kuntal Misra, Andrea Pastorello +30
We present a comprehensive analysis of the long-term photometric and spectroscopic monitoring campaign of the Type IIn Supernova (SN) 2024kgi. The SN reaches at peak an -band ab…
SN 2022xus: bridging the gap between Type IIP and IIL supernovae
Monalisa Dubey, Kuntal Misra, Naveen Dukiya +16
We present optical photometric and spectroscopic observations of the Type~II supernova SN~2022xus. The SN reached its peak {\em V} band magnitude of mag within 7 day…
SN 2024dy: Dust formation in a long-lived Type IIn supernova and constraints on the dust mass
Sota Goto, Masayuki Yamanaka, Koji S. Kawabata +10
Type~IIn supernovae (SNe) are a subclass of core-collapse SNe powered by interaction between the ejecta and the dense circumstellar material. Among them, long-lived Type~IIn events…
SN 2023zcu: A Type IIP SN with Early Flash Features
Monalisa Dubey, Kuntal Misra, Géza Csörnyei +51
We present a detailed photometric and spectroscopic analysis of the Type IIP supernova SN~2023zcu, which exploded in the galaxy NGC~2139 (redshift = 0.006). SN~2023zcu exhibits…
Progenitor Insights of Type IIP SN 2018pq: A Comprehensive Photometric and Spectroscopic Study
Monalisa Dubey, Kuntal Misra, Raya Dastidar +10
We present high-cadence photometric and low-resolution (R 400--700) optical spectroscopic observations of Type IIP supernova, SN~2018pq, which exploded on the outskirts of t…
SN 2023xgo: Helium-rich Type Icn or Carbon-Flash Type Ibn supernova?
Anjasha Gangopadhyay, Jesper Sollerman, Konstantinos Tsalapatas +35
We present observations of SN~2023xgo, a transitional Type Ibn/Icn supernova, from to ~days relative to the -band peak. Early spectra show C~III emission rem…
SN 2023vbg: A Type IIn Supernova Resembling SN 2009ip, with a Long-Duration Precursor and Early-Time Bump
Sota Goto, Masayuki Yamanaka, Takahiro Nagayama +9
Type IIn supernovae (SNe) resembling SN 2009ip (09ip-like SNe) originate from the interaction between circumstellar material (CSM) and the ejecta. This subclass not only shares sim…
