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…
Gamma-ray signature of superluminous supernovae: Fermi-LAT GeV detection of SN 2017egm and evidence of a central engine
F. Acero, A. Acharyya, A. Adelfio +116
Superluminous supernovae (SLSNe) are a rare class of transients with peak luminosities 10-100 times greater than those of standard core-collapse supernovae (SNe). The mechanisms po…
Radiation-mediated shocks in gamma-ray bursts: spectral evolution
Filip Alamaa, Frédéric Daigne
Radiation-mediated shocks (RMSs) occurring below the photosphere in a gamma-ray burst (GRB) jet could play a crucial role in shaping the prompt emission. In this paper, we study th…
Magnetic field spreading from stellar and galactic dynamos into the exterior
Axel Brandenburg, Oindrila Ghosh, Franco Vazza +1
The exteriors of stellar and galactic dynamos are usually modeled as current-free potential fields. A more realistic description might instead be that of a force-free magnetic fiel…
Emission line models for the lowest mass core-collapse supernovae -- II. 3D NLTE radiative transfer modelling of a neutrino-driven explosion
Bart F. A. van Baal, Anders Jerkstrand, Daniel Kresse +1
The nebular phase of a supernova (SN) occurs several months to years after the explosion, with asymmetries created by the explosion encoded into the line profiles of the emission l…
AT2024wpp: An Extremely Luminous Fast Ultraviolet Transient Powered by Accretion onto a Black Hole
Daniel A. Perley, Anna Y. Q. Ho, Zoë McGrath +69
We present the discovery of AT 2024wpp ("Whippet"), a fast and luminous 18cow-like transient. At a redshift of z=0.0868, revealed by Keck Cosmic Web Imager spectroscopy of its fain…
