Axion search with telescope for radio astronomy (ASTRA): forecast for observations between 0.5 and 4~GHz
Utkarsh Bhura, David J. E. Marsh, Bradley R. Johnson +8
Axion dark matter (DM) is predicted to convert into radio waves in neutron star magnetospheres. We assess the detectability of this signal using a 5 m radio telescope to be install…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Prospects for relic neutrino detection using nuclear spin experiments
Yeray Garcia del Castillo, Giovanni Pierobon, Dipan Sengupta +1
Direct detection of the cosmic neutrino background (CB) remains one of the most formidable experimental challenges in modern physics. In this work, we extend recent studies of…
Towards a precision calculation of in the Standard Model IV: Estimating the impact of positronium formation
Tobias Binder, Marco Drewes, Yannis Georis +3
We present a first assessment of how the previously unexplored effect of positronium formation can impact on the value of the effective number of neutrino species in the Standard M…
Fine-grained dark matter substructure and axion haloscopes
Ciaran A. J. O'Hare, Giovanni Pierobon
The velocity distribution of cold dark matter within galaxies is expected to exhibit ultra-fine-grained substructure as a result of the many foldings of an initially smooth phase-s…
One trick to treat them all: SuperEasy linear response for any hot dark matter in -body simulations
Giovanni Pierobon, Markus R. Mosbech, Amol Upadhye +1
We generalise the SuperEasy linear response method, originally developed to describe massive neutrinos in cosmological -body simulations, to any hot dark matter (HDM) species wi…
