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…

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.…

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…

Updated bounds on Axion-Like Particle Dark Matter with the optical MUSE-Faint survey

Elisa Todarello

Bounds are derived on the axion-like particle (ALP) to two-photon coupling in the mass range eV. The bounds are obtained by searching for the signal from ALP decay in t…

Robust bounds on ALP dark matter from dwarf spheroidal galaxies in the optical MUSE-Faint survey

Elisa Todarello, Marco Regis, Javier Reynoso-Cordova +5

Nearby dwarf spheroidal galaxies are ideal targets in the search for indirect dark matter (DM) signals. In this work, we analyze MUSE spectroscopic observations of a sample of five…

The Second Radio Synchrotron Background Workshop: Conference Summary and Report

J. Singal, N. Fornengo, M. Regis +24

We summarize the second radio synchrotron background workshop, which took place June 15-17, 2022 in Barolo, Italy. This meeting was convened because available measurements of the d…
