SN 2008jb: A "Lost" Core-Collapse Supernova in a Star-Forming Dwarf Galaxy at ~10 Mpc
Jose L. Prieto, J. C. Lee, A. J. Drake +9
We present the discovery and follow-up observations of SN 2008jb, a core-collapse supernova in the dwarf irregular galaxy ESO 302-14 at 9.6 Mpc. This transient was missed by galaxy…
The next-generation liquid-scintillator neutrino observatory LENA
Michael Wurm, John F. Beacom, Leonid B. Bezrukov +74
We propose the liquid-scintillator detector LENA (Low Energy Neutrino Astronomy) as a next-generation neutrino observatory on the scale of 50 kt. The outstanding successes of the B…
Reconstruction of supernova ν_μ, ν_τ, anti-ν_μ, and anti-ν_τ neutrino spectra at scintillator detectors
Basudeb Dasgupta, John F. Beacom
We present a new technique to directly reconstruct the spectra of mu/tau neutrinos and antineutrinos from a supernova, using neutrino-proton elastic scattering events (nu+p to nu+p…
The Cosmic Core-collapse Supernova Rate does not match the Massive-Star Formation Rate
Shunsaku Horiuchi, John F. Beacom, Christopher S. Kochanek +3
We identify a "supernova rate problem": the measured cosmic core-collapse supernova rate is a factor of ~ 2 smaller (with significance ~ 2 sigma) than that predicted from the measu…
