Dust Without Na I D Trace: The Case of Highly Attenuated Type Ib SN 2024vjc

Javier Silva-Farfán, Keiichi Maeda, Andrea Pastorello +19

Understanding dust attenuation toward extragalactic transients is critical for recovering their intrinsic properties and probing the local environments of distant galaxies. A popul…

GRB 250424A: A Case Study of Energy Injection with Multiwavelength Observations

Yifang Liang, Yun Wang, WeiKang Zheng +61

We present a comprehensive multiwavelength analysis of the long-duration gamma-ray burst (GRB) 250424A. Our dataset spans from the prompt gamma-ray emission to late-time optical mo…

SN 2024abvb: a Type Ibn/Icn supernova with evidence of helium and an extreme offset from its host galaxy

Callum Aster, Cosimo Inserra, Andrea Pastorello +27

We present spectroscopic and photometric observations and analysis of SN 2024abvb, a peculiar transitional Type Ibn/Icn supernova located at an unusually large projected distance f…

Fires in the deep: The luminosity distribution of early-time gamma-ray-burst afterglows in light of the Gamow Explorer sensitivity requirements

D. A. Kann, N. E. White, G. Ghirlanda +58

Gamma-ray bursts (GRBs) are ideal probes of the Universe at high redshift (z > 5), pinpointing the locations of the earliest star-forming galaxies and providing bright backlights t…

Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV

A. Pastorello, G. Valerin, M. Fraser +77

We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…

SN 2021foa, a transitional event between a Type IIn (SN 2009ip-like) and a Type Ibn supernova

A. Reguitti, A. Pastorello, G. Pignata +16

We present photometric and spectroscopic data of the unusual interacting supernova (SN) 2021foa. It rose to an absolute magnitude peak of mag in 20 days. The initial ligh…
