If dark matter has a sizable scattering cross section with nucleons, it can efficiently be captured by a neutron star. Its energy is then transferred to the neutron star as heat through the scattering and annihilation inside the star. This heating effect may be detectable via dedicated temperature observations of nearby old pulsars, providing an alternative method for dark matter searches. In this paper, we show that for electroweak multiplet dark matter this search strategy can probe the…

Improved White Dwarves Constraints on Inelastic Dark Matter and Left-Right Symmetric Models

. 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

Neutron Star Heating in Dark Matter Models for the Muon $g-2$ Discrepancy

The observed value of the muon magnetic dipole moment, which deviates from the Standard Model prediction by 4 . 2 σ , can be explained in models with weakly-interacting massive particles (WIMPs)



Hypercharged dark matter and direct detection as a probe of reheating.

The interesting and generic case of hypercharged dark matter is considered, which can allow for heavy dark matter masses without spoiling testability, and the extent to which future experiments may be able to make such a determination is discussed.

Warming nuclear pasta with dark matter: kinetic and annihilation heating of neutron star crusts

Neutron stars serve as excellent next-generation thermal detectors of dark matter, heated by the scattering and annihilation of dark matter accelerated to relativistic speeds in their deep

Electroweakly interacting Dirac dark matter

We consider a class of fermionic dark matter candidates that are charged under both the SU(2)$_L$ and U(1)$_Y$ gauge interactions. In this case a certain amount of dark matter-Higgs couplings, which

We study the heat capacity and neutrino emission reactions (direct and modified Urca processes, nucleon-nucleon bremsstrahlung, Cooper pairing of nucleons) in matter of supranuclear density of the

Improved treatment of dark matter capture in neutron stars

Neutron stars provide a cosmic laboratory to study the nature of dark matter particles and their interactions. Dark matter can be captured by neutron stars via scattering, where kinetic energy is

Minimal Consistent Dark Matter models for systematic experimental characterisation: Fermion Dark Matter

The search for a Dark Matter particle is the new grail and hard-sought nirvana of the particle physics community. From the theoretical side, it is the main challenge to provide a consistent and

Thermal and Nonthermal Emission in the Optical-UV Spectrum of PSR B0950+08

Based on recent Hubble Space Telescope (HST) observations in the far-UV and ground-based observations in optical bands, Pavlov and colleagues have revealed a thermal component in the spectrum of the

Astroparticle Physics with Compact Objects

Probing the existence of hypothetical particles beyond the Standard model often deals with extreme parameters: large energies, tiny cross-sections, large time scales, etc. Sometimes, laboratory

SO(10) grand unification with minimal dark matter and color octet scalars

The minimal dark matter (MDM) scenario is a very simple framework of physics beyond the Standard Model (SM) to supplement the SM with a DM candidate. In this paper, we consider an ultraviolet

Scattering Searches for Dark Matter in Subhalos: Neutron Stars, Cosmic Rays, and Old Rocks.

In many cosmologies dark matter clusters on subkiloparsec scales and forms compact subhalos, in which the majority of Galactic dark matter could reside. Null results in direct detection experiments
