High Energy Emission of Symbiotic Recurrent Novae: RS Oph and V407 Cyg
Open Astronomy, 2012 Recurrent novae occurring in symbiotic binaries are candidate sources of high energy photons, reaching GeV energies. Such emission is a consequence of particle acceleration leading to pion production.

The Most Luminous Supernovae [PDF]
Annual Review of Astronomy and Astrophysics, 2018 Over a decade ago, a group of supernova explosions with peak luminosities far exceeding (often by >100 times) those of normal events has been identified. These superluminous supernovae (SLSNe) have been a focus of intensive study.

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]
, 2014 X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

Pulsational Pair-instability Supernovae in Very Close Binaries [PDF]
Astrophysical Journal, 2018 Pair-instability and pulsational pair-instability supernovae (PPISNe) have not been unambiguously observed so far. They are, however, promising candidates for the progenitors of the heaviest binary black hole (BBH) mergers detected. If these BBHs are the

Carnegie Supernova Project: Classification of Type Ia Supernovae [PDF]
The Astrophysical Journal, 2020 Abstract We use the spectroscopy and homogeneous photometry of 97 Type Ia supernovae (SNe Ia) obtained by the Carnegie Supernova Project as well as a subset of 36 SNe Ia presented by Zheng et al. to examine maximum-light correlations in a four-dimensional (4D) parameter space: B-band absolute magnitude, M

A low energy core-collapse supernova without a hydrogen envelope [PDF]
, 2009 The final fate of massive stars depends on many factors, including mass, rotation rate, magnetic fields and metallicity. Theory suggests that some massive stars (initially greater than 25-30 solar masses) end up as Wolf-Rayet stars which are deficient in

Very massive stars, pair-instability supernovae and intermediate-mass black holes with the sevn code [PDF]
, 2017 Understanding the link between massive ($\gtrsim 30$ M$_{\odot{}}$) stellar black holes (BHs) and their progenitor stars is a crucial step to interpret observations of gravitational-wave events.

The Gravitational Wave Signal from Core-collapse Supernovae [PDF]
Astrophysical Journal, 2018 We study gravitational waves (GWs) from a set of 2D multigroup neutrino radiation hydrodynamic simulations of core-collapse supernovae (CCSNe). Our goal is to systematize the current knowledge about the post-bounce CCSN GW signal and recognize the ...

Critical Tests of Leading Gamma Ray Burst Theories
Universe, 2022 It has been observationally established that supernovae (SNe) of Type Ic produce long duration gamma-ray bursts (GRBs) and that neutron star mergers generate short hard GRBs.
