Search for 511 keV emission in satellite galaxies of the Milky Way with INTEGRAL/SPI
Context: The positron (e+) annihilation γ-ray signal in the Milky Way (MW) shows a puzzling morphology: a very bright bulge and a very low surface-brightness disk. A coherent explanation of the e+
Spectral analysis of the high-energy IceCube neutrinos
A full energy and flavor-dependent analysis of the three-year high-energy IceCube neutrino events is presented. By means of multidimensional fits, we derive the current preferred values of the
Analysis of the 4-year IceCube high-energy starting events
After four years of data taking, the IceCube neutrino telescope has detected 54 high-energy starting events (HESE, or contained-vertex events) with deposited energies above 20 TeV. They represent the
Physics from solar neutrinos in dark matter direct detection experiments
A bstractThe next generation of dark matter direct detection experiments will be sensitive to both coherent neutrino-nucleus and neutrino-electron scattering. This will enable them to explore aspects
Simulated heat storage in a perennially ice-covered high Arctic lake: Sensitivity to climate change
[1] Perennially ice-covered, meromictic lakes occur along the northern coast of Ellesmere Island in the Canadian high Arctic and have distinctive conductivity and temperature profiles. They are
Implications of solar wind measurements for solar models and composition
We critically examine recent claims of a high solar metallicity by von Steiger & Zurbuchen (2016, vSZ16) based on in situ measurements of the solar wind, rather than the standard spectroscopically
Global analyses of Higgs portal singlet dark matter models using GAMBIT
TLDR
Global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks are presented and DDCalc2.0, a tool for calculating direct detection observables and likelihoods for arbitrary non-relativistic effective operators is presented.
Dark matter annihilation to neutrinos
We review the annihilation of dark matter into neutrinos over a range of dark matter masses from MeV$/c^2$ to ZeV$/c^2$. Thermally-produced models of dark matter are expected to self-annihilate to
Interacting dark matter contribution to the Galactic 511 keV gamma ray emission: constraining the morphology with INTEGRAL/SPI observations
We compare the full-sky morphology of the 511 keV gamma ray excess measured by the INTEGRAL/SPI experiment to predictions of models based on dark matter (DM) scatterings that produce low-energy
Ruling out the light weakly interacting massive particle explanation of the Galactic 511 keV line
Over the past few decades, an anomalous 511 keV gamma-ray line has been observed from the center of the Milky Way. Dark matter (DM) in the form of light ($\ensuremath{\lesssim}10\text{ }\text{
