Superluminous Supernovae [PDF]

Space Science Reviews, 2018
Superluminous supernovae are a new class of supernovae that were recognized about a decade ago. Both observational and theoretical progress has been significant in the last decade.

Luminous Supernovae [PDF]

Science, 2012
Supernovae (SNe), the luminous explosions of stars, were observed since antiquity, with typical peak luminosity not exceeding 1.2x10^{43} erg/s (absolute magnitude >-19.5 mag).

Fast collective neutrino oscillations inside the neutrino sphere in core-collapse supernovae [PDF]

Physical Review D, 2019
Neutrinos are believed to have a key role in the explosion mechanism of core-collapse \mbox{supernovae} as they carry most of the energy released by the gravitational collapse of a massive star.

Hydrodynamics of core-collapse supernovae and their progenitors [PDF]

, 2020
Multi-dimensional fluid flow plays a paramount role in the explosions of massive stars as core-collapse supernovae. In recent years, three-dimensional (3D) simulations of these phenomena have matured significantly.

First Observations of SN 1604 (Kepler’s Supernova)

Universe, 2021
A supernova close enough to the Earth is a spectacular event: it can appear as a “new star” as luminous as Venus, or even more, visible for several days.

Muons in Supernovae: Implications for the Axion-Muon Coupling. [PDF]

Physical Review Letters, 2020
The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting protoneutron star.

Effect of Protoneutron Star Magnetized Envelops in Neutrino Energy Spectra

Particles, 2022
The neutrino dynamics in hot and dense magnetized matter, which corresponds with protoneutron star envelopes in the core collapse supernova explosions, is considered.

The All-Sky Automated Survey for Supernovae (ASAS-SN) Light Curve Server v1.0 [PDF]

, 2017
The All-Sky Automated Survey for Supernovae (ASAS-SN) is working toward imaging the entire visible sky every night to a depth of V ∼ 17 mag. The present data covers the sky and spans ∼2–5 years with ∼100–400 epochs of observation. The data should contain

Black Holes as Evidence of God’s Care

Religions, 2021
As black holes gravitationally draw matter toward their event horizons, a high proportion of this matter is converted into energy. Radiation from this conversion process is deadly for advanced life.

Equations of state for supernovae and compact stars [PDF]

, 2016
A review is given of various theoretical approaches for the equation of state (EoS) of dense matter, relevant for the description of core-collapse supernovae, compact stars, and compact star mergers.
