Probing the Fundamental Nature of Particle Dark Matter
Marco Regis, Aritra Basu, Geoff Beck +7
Understanding the fundamental nature of dark matter (DM) is one of the most significant scientific challenges of our time. A compelling hypothesis is that DM consists of a new, yet…
NuSTAR as an Axion Helioscope: probing axion-nucleon and axion-electron couplings
Tiziano Zanzarella, Francisco R. Candón, Maurizio Giannotti +5
We investigate solar X-ray observations as a probe of axions and axion-like particles. These particles can be produced in the interior of the Sun via the conversion of thermal phot…
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…
New bounds on Axion-Like Particles in the Ultraviolet from Legacy Data
Elisa Todarello
We use legacy data from the Hubble Space Telescope (HST) and the International Ultraviolet Explorer (IUE) to search for a spectral line from the spontaneous decay of axion-like par…
NuSTAR as an Axion Helioscope
J. Ruz, E. Todarello, J. K. Vogel +11
We present a novel approach to investigating axions and axion-like particles (ALPs) by studying their potential conversion into X-rays within the Sun's atmospheric magnetic field.…
Bounds on Axions-Like Particles Shining in the Ultra-Violet
Elisa Todarello, Marco Regis
Axion-like particles (ALPs) can decay into two photons with a rest-frame frequency given by half of the ALP mass. This implies that ultra-violet searches can be used to investigate…
