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…
Searching for dark matter X-ray lines from the Large Magellanic Cloud with eROSITA
Jorge Terol Calvo, Marco Taoso, Andrea Caputo +2
We perform a search for an X-ray monochromatic line arising from dark matter (DM) decay in the halo of the Large Magellanic Cloud. An emission line can be expected from two well-mo…
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…
The diffusion coefficient in the Large Magellanic Cloud
Javier Reynoso-Cordova, Daniele Gaggero, Marco Regis +1
The Large Magellanic Cloud (LMC) is the largest satellite galaxy of the Milky Way and provides a unique laboratory for high-energy astrophysics and dark matter studies. In this wor…
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.…
