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.

Supernovae and the Arrow of Time
Entropy, 2022 Supernovae are explosions of stars and are a central problem in astrophysics. Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities develop during the star’s explosion and lead to intense interfacial RT/RM mixing of the star materials.

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.

Galaxies, 2022 The difference from 4 to 6 σ in the Hubble constant (H0) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by the Planck data) still challenges the astrophysics and

New Hubble Space Telescope Discoveries of Type Ia Supernovae at z ≥ 1: Narrowing Constraints on the Early Behavior of Dark Energy [PDF]
, 2006 We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to trace the history of cosmic expansion over the last 10 billion yr. These objects, which include 13 spectroscopically confirmed SNe Ia at z ≥

possis: predicting spectra, light curves, and polarization for multidimensional models of supernovae and kilonovae [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present possis, a time-dependent three-dimensional Monte Carlo code for modelling radiation transport in supernovae and kilonovae. The code incorporates wavelength- and time-dependent opacities, and predicts viewing-angle dependent spectra, light ...
