Can a supernova be located by its neutrinos? [PDF]

, 1999
A future core-collapse supernova in our Galaxy will be detected by several neutrino detectors around the world. The neutrinos escape from the supernova core over several seconds from the time of collapse, unlike the electromagnetic radiation, emitted ...

Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins

Journal of Big History, 2018
For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above ...

Untangling supernova-neutrino oscillations with beta-beam data [PDF]

, 2008
Recently, we suggested that low-energy beta-beam neutrinos can be very useful for the study of supernova neutrino interactions. In this paper, we examine the use of a such experiment for the analysis of a supernova neutrino signal.

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

Symmetry energy impact in simulations of core-collapse supernovae [PDF]

, 2014
We present a review of a broad selection of nuclear matter equations of state (EOSs) applicable in core-collapse supernova studies. The large variety of nuclear matter properties, such as the symmetry energy, which are covered by these EOSs leads to ...

Ghost particles in the universe: Neutrinos in astrophysics and cosmology

Mètode Science Studies Journal: Annual Review, 2017
  Neutrinos are nearly massless and very difficult to detect because they interact so very weakly. Sixty years after seeing the first of these «ghost particles» we know a lot about their properties.

The Search for Supernova-produced Radionuclides in Terrestrial Deep-sea Archives [PDF]

, 2012
An enhanced concentration of 60Fe was found in a deep ocean's crust in 2004 in a layer corresponding to an age of ~2 Myr. The confirmation of this signal in terrestrial archives as supernova-induced and detection of other supernova-produced radionuclides

An outburst from a massive star 40 days before a supernova explosion [PDF]

, 2013
Various lines of evidence suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as a supernova. Interestingly, several models predict such pre-explosion outbursts. Establishing a causal connection between these

Simulations of stripped core-collapse supernovae in close binaries [PDF]

, 2015
We perform smoothed-particle hydrodynamical simulations of the explosion of a helium star in a close binary system, and study the effects of the explosion on the companion star as well as the effect of the presence of the companion on the supernova ...

Testing homogeneity with galaxy number counts : light-cone metric and general low-redshift expansion for a central observer in a matter dominated isotropic universe without cosmological constant

, 2009
As an alternative to dark energy it has been suggested that we may be at the center of an inhomogeneous isotropic universe described by a Lemaitre-Tolman-Bondi (LTB) solution of Einstein's field equations.
