Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities [PDF]

, 2019
There is now solid experimental evidence of at least one supernova explosion within 100 pc of Earth within the last few million years, from measurements of the short-lived isotope ⁶⁰Fe in widespread deep-ocean samples, as well as in the lunar regolith ...

Supernova Dust Evolution Probed by Deep-sea 60Fe Time History [PDF]

The Astrophysical Journal, 2023
There is a wealth of data on live, undecayed ^60 Fe ( t _1/2 = 2.6 Myr) in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as originating from the recent explosions of at least two near-Earth supernovae.

Inference of bipolar neutrino flavor oscillations near a core-collapse supernova based on multiple measurements at Earth [PDF]

Physical Review D, 2022
Neutrinos in compact-object environments, such as core-collapse supernovae, can experience various kinds of collective effects in flavor space, engendered by neutrino-neutrino interactions.

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.

Probing neutrino mass hierarchies and $\phi_{13}$ with supernova neutrinos [PDF]

, 2006
We investigate the feasibility of probing the neutrino mass hierarchy and the mixing angle $\phi_{13}$ with the neutrino burst from a future supernova.

Superluminous supernovae: No threat from Eta Carinae [PDF]

, 2007
Recently Supernova 2006gy was noted as the most luminous ever recorded, with a total radiated energy of ~10^44 Joules. It was proposed that the progenitor may have been a massive evolved star similar to eta Carinae, which resides in our own galaxy at a ...

Effects of Neutrino Oscillation on the Supernova Neutrino Spectrum [PDF]

, 2001
The effects of three-flavor neutrino oscillation on the supernova neutrino spectrum are studied. We calculate the expected event rate and energy spectra, and their time evolution at the Superkamiokande (SK) and the Sudbury Neutrino Observatory (SNO), by ...

Physics with Supernovae [PDF]

, 2002
Core-collapse supernovae (SNe) are powerful neutrino sources and as such important targets for the growing array of neutrino observatories. We review the current status of SN theory and the expected characteristics of the neutrino signal. After recalling

Superluminal neutrinos in long baseline experiments and SN1987a [PDF]

, 2011
Precise tests of Lorentz invariance in neutrinos can be performed using long baseline experiments such as MINOS and OPERA or neutrinos from astrophysical sources. The MINOS collaboration reported a measurement of the muonic neutrino velocities that hints
