Supernova triggers for end-Devonian extinctions [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 The Late Devonian was a protracted period of low speciation resulting in biodiversity decline, culminating in extinction events near the Devonian–Carboniferous boundary.

THE HUBBLE SPACE TELESCOPE CLUSTER SUPERNOVA SURVEY. V. IMPROVING THE DARK-ENERGY CONSTRAINTS ABOVE z > 1 AND BUILDING AN EARLY-TYPE-HOSTED SUPERNOVA SAMPLE [PDF]
, 2011 We present Advanced Camera for Surveys, NICMOS, and Keck adaptive-optics-assisted photometry of 20 Type Ia supernovae (SNe Ia) from the Hubble Space Telescope (HST) Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval 0.623 < z

The fast, luminous ultraviolet transient AT2018cow: extreme supernova, or disruption of a star by an intermediate-mass black hole? [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Wide-field optical surveys have begun to uncover large samples of fast (t_rise 10 days. The spectrum remains extremely hot throughout its evolution, and the photospheric radius contracts with time (receding below ...

A Probabilistic Approach to Classifying Supernovae Using Photometric Information [PDF]
, 2006 This paper presents a novel method for determining the probability that a supernova candidate belongs to a known supernova type (such as Ia, Ibc, IIL, \emph{etc.}), using its photometric information alone. It is validated with Monte Carlo, and both space-

Is there a supernova bound on axions? [PDF]
, 2019 We present a critical assessment of the SN1987A supernova cooling bound on axions and other light particles. Core-collapse simulations used in the literature to substantiate the bound omitted from the calculation the envelope exterior to the proto ...

A Multidimensional Multicomponent Gas Dynamic with the Neutrino Transfer in Gravitational Collapse
Universe, 2022 The self-consistent problem of gravitational collapse is solved using 2D gas dynamics with taking into account the neutrino transfer in the flux-limited diffusion approximation.

An Open Catalog for Supernova Data [PDF]
, 2016 We present the Open Supernova Catalog, an online collection of observations and metadata for presently 36,000+ supernovae and related candidates. The catalog is freely available on the web (https://sne.space), with its main interface having been designed

SuperNNova: an open-source framework for Bayesian, neural network-based supernova classification [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We introduce SuperNNova, an open-source supernova photometric classification framework that leverages recent advances in deep neural networks. Our core algorithm is a recurrent neural network (RNN) that is trained to classify light curves using only ...

Probing r-Process Production of Nuclei Beyond Bi209 with Gamma Rays [PDF]
, 1999 We estimate gamma-ray fluxes due to the decay of nuclei beyond Bi209 from a supernova or a supernova remnant assuming that the r-process occurs in supernovae.

Confined dense circumstellar material surrounding a regular type II supernova [PDF]
Nature Physics, 2017 With the advent of new wide-field, high-cadence optical transient surveys, our understanding of the diversity of core-collapse supernovae has grown tremendously in the last decade.
