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…
Late-time evolution of the interacting stripped-envelope supernova 2017dio
C. Humina, C. P. Gutiérrez, H. Kuncarayakti +14
The discovery of stripped-envelope supernovae (SNe) interacting with dense circumstellar medium (CSM) challenges our current understanding of massive star evolution. We present lat…
GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow
Ramandeep Gill, Rosa L. Becerra, Antonio de Ugarte Postigo +54
We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt…
GRB 210704A: A Luminous Fast Blue Transient in a GRB Afterglow at
Daniëlle L. A. Pieterse, Andrew J. Levan, Maria E. Ravasio +27
We present detailed, multi-wavelength analysis of GRB 210704A: a Fermi Gamma-ray Burst Monitor discovered and Fermi Large Area Telescope (LAT) detected gamma-ray burst (GRB). The b…
The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases
A. Fiore, A. Kozyreva, L. Yan +40
Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…
GRB 180728A and SN 2018fip: the nearest high-energy cosmological gamma-ray burst with an associated supernova
A. Rossi, L. Izzo, K. Maeda +29
The long GRB 180728A, at a redshift of , stands out due to its high isotropic energy of erg, in contrast with most events at redshif…
