Photo- and Hadrodisintegration constraints on massive relics decaying into neutrinos
Sara Bianco, Paul Frederik Depta, Jonas Frerick +3
We perform a detailed study of the cosmological constraints on the decay of a relic particle into neutrinos, , in particular those arising from the obs…
Riding the dark matter wave: Novel limits on general dark photons from LISA Pathfinder
Jonas Frerick, Joerg Jaeckel, Felix Kahlhoefer +1
We note the possibility to perform a parametrically improved search for gauged baryon () and baryon minus lepton () Dark Photon Dark Matter (DPDM) using auxiliary channel d…
view of the sunrise: Boosting helioscopes with angular information
Jonas Frerick, Felix Kahlhoefer, Kai Schmidt-Hoberg
The Sun may copiously produce hypothetical light particles such as axions or dark photons, a scenario which can be experimentally probed with so-called helioscopes. Here we investi…
The ups and downs of inelastic dark matter: Electron recoils from terrestrial upscattering
Timon Emken, Jonas Frerick, Saniya Heeba +1
The growing interest in the interactions between dark matter particles and electrons has received a further boost by the observation of an excess in electron recoil events in the X…
Improved Big Bang Nucleosynthesis constraints on decaying massive relics
Sara Bianco, Jonas Frerick, Marco Hufnagel +1
We present updated and improved Big Bang Nucleosynthesis (BBN) constraints on heavy, long-lived beyond the Standard Model (BSM) relics decaying into pairs of Standard Model pa…
Precision Solar System Dynamics for Ultralight Dark Matter Search
Jonas Frerick, Hyungjin Kim, Felix Kling
Ultralight dark matter exhibits an order-one density fluctuation at the scale of its wavelength. This density fluctuation exists across the entire dark matter halo and interacts wi…
