Dark Sectors 2016 Workshop: Community Report
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the…

Primordial Black Holes as a Dark Matter Candidate Are Severely Constrained by the Galactic Center 511 keV γ-Ray Line.
TLDR
These constraints are the most stringent in the literature and show that primordial black holes contribute to less than 1% of the dark matter density.

Neutrino and Positron Constraints on Spinning Primordial Black Hole Dark Matter.
TLDR
A comprehensive study of the detectability of primordial black holes with non-negligible spin, via the searches for the neutrinos and positrons in the MeV energy range, finds that spin-a fundamental property that has a strong effect on its evaporation rate, is found.

INTEGRAL constraints on primordial black holes and particle dark matter
The International Gamma-Ray Astrophysics Laboratory ($INTEGRAL$) satellite has yielded unprecedented measurements of the soft gamma-ray spectrum of our Galaxy. Here we use those measurements to set…

Supernova Physics at DUNE
The DUNE/LBNF program aims to address key questions in neutrino physics and astroparticle physics. Realizing DUNE's potential to reconstruct low-energy particles in the 10-100 MeV energy range will…

IC at IC: IceCube can constrain the intrinsic charm of the proton
The discovery of extraterrestrial neutrinos in the $\sim$ 30 TeV -- PeV energy range by IceCube provides new constraints on high energy astrophysics. An important background to the signal are the…

Galactic center radio constraints on gamma-ray lines from dark matter annihilation
Recent evidence for one or more gamma-ray lines at ~ 130 GeV in the Fermi-LAT data from the Galactic Center has been interpreted as a hint for dark matter annihilation to Z{\gamma} or H{\gamma} with…

Testing the Dark Matter Scenario for PeV Neutrinos Observed in IceCube.
TLDR
With several-year observations by next-generation telescopes such as IceCube-Gen2, muon neutrino searches for nearby dark matter halos such as the Virgo cluster should allow us to rule out or support the dark matter models, independently of γ-ray and anisotropy tests.

Cuckoo’s eggs in neutron stars: can LIGO hear chirps from the dark sector?
A bstractWe explore in detail the possibility that gravitational wave signals from binary inspirals are affected by a new force that couples only to dark matter particles. We discuss the impact of…

Demystifying the PeV Cascades in IceCube: Less (Energy) is More (Events)
The IceCube neutrino observatory has detected two cascade events with energies near 1 PeV. Without invoking new physics, we analyze the source of these neutrinos. We show that atmospheric…
