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…
On the potential of pseudo-scalar dark energy
Andrea Minotti, Yunzhi Wu, Marco Regis
A cosmological pseudo-scalar field provides a compelling realization of dynamical dark energy (DE). If its coupling to photons is non-negligible, the cosmic microwave background ac…
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 axion-like particles with SPHEREx
Marco Regis, Marco Taoso, Jorge Terol Calvo
We study prospects to detect axion-like particles (ALPs) with the upcoming near-infrared telescope SPHEREx. The signal under investigation is the ALP decay into two photons. Assumi…
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.…
Constraints on the origin of the radio synchrotron background via angular correlations
Elisa Todarello, Marco Regis, Federico Bianchini +7
The origin of the radio synchrotron background (RSB) is currently unknown. Its understanding might have profound implications in fundamental physics or might reveal a new class of…
