Python and Julia tools for dark matter detection calculations
New software implementations accelerate calculations for directional dark matter detection using anisotropic crystal targets, enabling faster signal-background discrimination.
Dark decay channels strengthen cosmological bounds on heavy neutral leptons
Cosmological analysis shows heavy neutral leptons with dark decay modes face stronger big bang nucleosynthesis constraints, not weaker ones, narrowing viable parameter space for terrestrial detection.
Cored stellar systems can remain stable in cuspy dark matter halos
—
in AstrophysicsSimulations demonstrate that cored stellar systems remain stable within cuspy dark matter halos over Hubble timescales, refuting recent claims that such configurations would falsify cold dark matter.
Dark matter halo alters black hole optics and thermodynamics
Exact black hole solution in cored Plummer dark matter halo showing modified photon dynamics, shadows, lensing, quasinormal modes, and novel phase transitions absent in Schwarzschild spacetime.
