We present the most comprehensive catalogue to date of Type I superluminous supernovae
(SLSNe), a class of stripped-envelope supernovae (SNe) characterized by exceptionally …

We present a detailed study on SN2019szu, a Type I superluminous supernova at z= 0.213
that displayed unique photometric and spectroscopic properties. Pan-STARRS and ZTF …

Abstract We present the Keck Infrared Transient Survey, a NASA Key Strategic Mission
Support program to obtain near-infrared (NIR) spectra of astrophysical transients of all types …

Kilonovae are a novel class of astrophysical transients, and the only observationally-
confirmed site of rapid neutron capture nucleosynthesis (the r-process) in the Universe. To …

I present a review of how late observations of supernovae, of the nebular phase, and much
later of supernova remnants (SNRs), and their analysis in 2023 made progress towards …

SN 2020zbf is a hydrogen-poor superluminous supernova (SLSN) at z= 0.1947 that shows
conspicuous C II features at early times, in contrast to the majority of H-poor SLSNe. Its peak …

In this study, we analyze the postmaximum spectra of a sample of 27 Type I superluminous
supernovae (SLSNe-I) in order to search for physical differences between the so-called …

Millisecond magnetars are widely suggested as the central engines powering hydrogen-
poor superluminous supernovae (SLSNe). These magnetars primarily lose huge rotational …

Abridged-Stars with ZAMS masses between 140 and $260 M_\odot $ are thought to explode
as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can …

Stars with zero-age main sequence masses between 140 and 260 M⊙ are thought to
explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe …
