Strong upper limits on sterile neutrino warm dark matter.
TL;DR: The limits on gamma-ray line emission from the Galactic center region obtained with the SPI spectrometer on the INTEGRAL satellite are used to set new constraints, which improve on the earlier bounds on mixing by more than 2 orders of magnitude, and thus strongly restrict a wide and interesting range of models.
Journal ArticleDOI
Conservative Constraints on Dark Matter Annihilation into Gamma Rays
TL;DR: In this paper, the authors used gamma-ray data from observations of the Milky Way, Andromeda (M31), and the cosmic background to calculate conservative upper limits on the dark matter self-annihilation cross section to monoenergetic gamma rays, over a wide range of dark matter masses.
Journal ArticleDOI
Sensitivity to θ 13 and δ in the decaying astrophysical neutrino scenario
TL;DR: In this paper, the decay of high-energy neutrinos from distant astrophysical sources would be revealed by flavor ratios that deviate strongly from the 1:1:1 :1$ expected from oscillations alone.
Journal ArticleDOI
DUNE as the Next-Generation Solar Neutrino Experiment.

TL;DR: The Deep Underground Neutrino Experiment (DUNE) has the potential to deliver world-leading results in solar neutrinos as discussed by the authors, with significant but feasible new efforts.

TL;DR: In this article, the authors used near-infrared photometric and spectroscopic data covering the rise and fall of ASASSN-14lp for more than 100 days and derived a distance modulus for NGC 4666 of 30.8 \pm 0.2$ corresponding to a distance of $14.7 \pm 1.5$ Mpc.
