The nearest neutron star candidate in a binary revealed by optical time-domain surveys [PDF]
Science China Physics Mechanics and Astronomy, 2022 The near-Earth (within ∼100 pc) supernova explosions in the past several million years can cause the global deposition of radioactive elements (e.g., ^60Fe) on Earth. The remnants of such supernovae are too old to be easily identified. It is therefore of

Fermi bubbles as sources of cosmic rays above 1 PeV
EPJ Web of Conferences, 2017 Fermi bubbles are giant gamma-ray structures extended north and south of the Galactic center with characteristic sizes of the order of 10 kpc discovered by the Fermi Large Area Telescope.

Magnetic Imprisonment of Dusty Pinballs by a Supernova Remnant [PDF]
Astrophysical Journal, 2018 Motivated by recent measurements of deposits of 60Fe on the ocean floor and the lunar surface, we model the transport of dust grains containing 60Fe from a near-Earth (i.e., within 100 pc) supernova (SN).

The MicroBooNE continuous readout stream for detection of supernova neutrinos [PDF]
Journal of Physics: Conference Series, 2019 Since the original detection of core-collapse supernova neutrinos in 1987, all large neutrino experiments seek to detect the neutrinos from the next nearby supernova.

Phosphorus in the Young Supernova Remnant Cassiopeia A [PDF]
Science, 2013 We Are Stardust Most of the universe's chemical elements were produced in stars, with the heaviest elements being produced when stars explode. Barlow et al. (p. 1343) used the Herschel Space Observatory to obtain submillimeter spectra of the Crab Nebula,

RADIOACTIVE IRON RAIN: TRANSPORTING 60Fe IN SUPERNOVA DUST TO THE OCEAN FLOOR [PDF]
, 2016 Several searches have found evidence of deposition, presumably from a near-Earth supernova (SN), with concentrations that vary in different locations on Earth.

Clustered supernovae as the sources of very-high-energy galactic cosmic rays
International Conference on Rebooting Computing, 2023 Although supernova remnants are believed to be the most plausible sources of galactic cosmic rays (CRs), it is yet unclear how they can accelerate particles beyond 1 PeV, especially when they evolve in the warm phase of the interstellar medium (ISM).

Decaying neutrinos and implications from the supernova relic neutrino observation [PDF]
, 2003 We propose that supernova relic neutrino (SRN) observation can be used to set constraints on the neutrino decay models. Because of the long distance scale from cosmological supernovae to the Earth, SRN have possibility to provide much stronger limit than

Flavor composition of supernova neutrinos [PDF]
Physical Review DPredicting the flavor composition of neutrinos from supernovae is a challenging task, primarily due to the high neutrino densities at their core. In such an environment, neutrino self-interactions give rise to collective effects that have dramatic yet ...

The Cassiopeia A Supernova Was of Type IIb [PDF]
Science, 2008 Cassiopeia A is the youngest supernova remnant known in the Milky Way and a unique laboratory for supernova physics. We present an optical spectrum of the Cassiopeia A supernova near maximum brightness, obtained from observations of a scattered light ...
