Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Astrophysical excesses include the Galactic Center GeV gamma-ray excess detected by the Fermi Gamma-Ray Space Telescope, the AMS antiproton and positron excesses, and the 511 and 3.5 keV X-ray lines. Direct detection excesses include the DAMA/LIBRA annual modulation signal, the XENON1T excess, and low-threshold excesses…

. Weakly Interacting Massive Particles (WIMPs) can be captured in compact stars such as white dwarves (WDs) leading to an increase in the star luminosity through their annihilation process. Using a

Search for New Physics in Electronic Recoil Data from XENONnT

A blind analysis of low-energy electronic-recoil data from the XENONnT dark matter experiment sets stringent new limits on solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter.

Foreground mismodeling and the point source explanation of the Fermi Galactic Center excess

The Fermi Large Area Telescope has observed an excess of $\ensuremath{\sim}\mathrm{GeV}$ energy gamma rays from the center of the Milky Way, which may arise from near-thermal dark matter

Probing dark matter annihilation in the Galaxy with antiprotons and gamma rays

A possible hint of dark matter annihilation has been found in Cuoco, Korsmeier and Krämer (2017) from an analysis of recent cosmic-ray antiproton data from AMS-02 and taking into account cosmic-ray

Possible Dark Matter Annihilation Signal in the AMS-02 Antiproton Data.

Using the latest AMS-02 cosmic-ray antiproton flux data, it is found that a dark matter signal is favored and incorporated into the model self-consistently under a Bayesian framework.

Multimessenger constraints on the dark matter interpretation of the Fermi -LAT Galactic Center excess

An excess of 𝛾 rays in the data measured by the Fermi Large Area Telescope in the direction of the Galactic center (GCE) has been reported in several publications. The characteristics of the GCE,

Atmospheric dark matter and XENON1T excess

Very recently, the Xenon1T collaboration has reported an intriguing electron recoil excess, which may imply for light dark matter. In order to interpret this anomaly, we propose the atmospheric dark

Novel Dark Matter Constraints from Antiprotons in Light of AMS-02.

Evaluating dark matter (DM) limits from cosmic-ray antiproton observations using the recent precise AMS-02 measurements finds a significant indication of a DM signal for DM masses near 80 GeV, with a hadronic annihilation cross section close to the thermal value.

Metastable dark matter mechanisms for INTEGRAL 511 keV $\gamma$ rays and DAMA/CoGeNT events

We explore dark matter mechanisms that can simultaneously explain the galactic 511 keV gamma rays observed by INTEGRAL/SPI, the DAMA/LIBRA annual modulation, and the excess of low-recoil dark matter

Cosmic-ray positrons strongly constrain leptophilic dark matter

Cosmic-ray positrons have long been considered a powerful probe of dark matter annihilation. In particular, myriad studies of the unexpected rise in the positron fraction have debated its dark matter

Direct Detection of Warm Dark Matter in the X-Ray

We point out a serendipitous link between warm dark matter (WDM) models for structure formation on the one hand and the high-sensitivity energy range (1-10 keV) for X-ray photon detection on the

Return of the WIMP: Missing energy signals and the Galactic Center excess

In a recent work, we emphasized that an excess in tri-lepton events plus missing energy observed by the ATLAS experiment at the LHC could be interpreted as a signal of low energy supersymmetry. In
