Core-collapse supernovae 2022prr, 2023ucy, and 2024ljc in the luminous infrared galaxy NGC 6745

K. K. Matilainen, E. Kankare, T. Nagao +19

The core-collapse supernovae (CCSNe) 2022prr, 2023ucy, and 2024ljc exploded within the central regions of the nearby luminous infrared galaxy (LIRG) NGC6745. We present our follow-…

SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss

Qian Zhai, Jujia Zhang, Xiaofeng Wang +51

We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…

SN 2025aico: Early observations of a faint Type IIb supernova with a low-mass envelope

J. -W. Zhao, A. Pastorello, B. Kumar +45

We aimed to investigate the physical properties and the underlying explosion mechanisms of the Type IIb SN 2025aico. Through a comprehensive analysis of early-phase optical light c…

The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve

Y. -Z. Cai, A. Pastorello, R. Chiba +65

We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…

The undetectable fraction of core-collapse supernovae in luminous infrared galaxies -- II. GSAOI/GeMS dataset

I. Mäntynen, E. Kankare, S. Mattila +7

Core-collapse supernovae (CCSNe) in luminous infrared galaxies (LIRGs) can have extreme line-of-sight host galaxy dust extinctions, which leads to a large fraction of the events re…

AT 2025abao: The fourth luminous red nova in M 31

A. Reguitti, A. Pastorello, G. Valerin +15

We present photometric and spectroscopic observations of the luminous red nova (LRN) AT 2025abao, the fourth discovered in M 31. The LRN, associated to the asymptotic giant branch…
