The Gamma-Ray Pulsar Phenomenology in View of 3D Kinetic Global Magnetosphere Models

The Astrophysical Journal, 2023
We develop kinetic plasma models of pulsar magnetospheres with magnetic-field-line-dependent plasma injection that reveal the importance of various magnetosphere regions in regulating the γ -ray emission. We set different particle injection rates for the

A minimal dark matter interpretation for the CRESST-II signal

European Physical Journal C: Particles and Fields, 2012
We report on the possible interpretation of the two proposed dark matter mass values m χ=11.6 GeV and m χ=25.3 GeV from CRESST-II within the framework of the Higgs portal minimal dark matter model. We find that the higher mass value yields a suitable fit

Spitzer IRS Observations of Titan as a Precursor to JWST MIRI Observations

The Planetary Science Journal, 2023
In this work, we present for the first time infrared spectra of Titan from the Spitzer Space Telescope (2004–2009). The data are from both the short wavelength–low resolution (SL; 5.13–14.29 μ m, R ∼ 60–127) and short wavelength–high resolution (SH; 9.89–

Dark-photon search using data from CRESST-II Phase 2

European Physical Journal C: Particles and Fields, 2017
Identifying the nature and origin of dark matter is one of the major challenges for modern astro and particle physics. Direct dark-matter searches aim at an observation of dark-matter particles interacting within detectors.

Investigating the Superorbital Modulations in 4U 1909 + 07, IGR J16418-4532, and IGR J16479-4514 with Swift XRT, BAT, and NuSTAR Observations

The Astrophysical Journal, 2023
A puzzling variety of superorbital modulations has been discovered in several supergiant high mass X-ray binaries (sgHMXBs). To investigate the mechanisms driving these superorbital modulations, we have analyzed long-term Neil Gehrels Swift Observatory ...

Results on light dark matter particles with a low-threshold CRESST-II detector [PDF]

, 2016
The CRESST-II experiment uses cryogenic detectors to search for nuclear recoil events induced by the elastic scattering of dark matter particles in CaWO$_4$ crystals. Given the low energy threshold of our detectors in combination with light target nuclei,

A Sub-GeV Low Mass Hidden Dark Sector of SU(2) H × U(1) X

Journal of High Energy Physics, 2021
We present a detailed study of the non-abelian vector dark matter candidate W t with a MeV–GeV low mass range, accompanied by a dark photon A′ and a dark Z′ of similar masses, in the context of a gauged two-Higgs-doublet model with the hidden gauge group

The Poker Face of Inelastic Dark Matter: Prospects at Upcoming Direct Detection Experiments

, 2010
The XENON100 and CRESST experiments will directly test the inelastic dark matter explanation for DAMA's 8.9? sigma anomaly. This article discusses how predictions for direct detection experiments depend on uncertainties in quenching factor measurements ...

Long-Range Forces in Direct Dark Matter Searches [PDF]

, 2011
We discuss the positive indications of a possible dark matter signal in direct detection experiments in terms of a mechanism of interaction between the dark matter particle and the nuclei occurring via the exchange of a light mediator, resulting in a ...
