In my talk I will present the possibility to set new constraints on axion-like particles using LIME or CYGNO04. I first studied the three production channels of axions in the Sun: photon coalescence, the Primakoff process, and plasmon decay, and reconstructed the resulting axion flux at Earth. then I focus on the population of axions that remain gravitationally trapped around the Sun, which...
The spherical proportional counter is a gaseous detector which is utilised for direct dark matter searches by the NEWS-G collaboration. The use of light gaseous targets, including He, CH4, Ne, etc., combined with a low energy threshold, enable access to the mass range from 0.05 to 10 GeV. The detector’s simple design also facilitates radio-pure detector construction. Thanks to the radial...
Recent geophysical studies indicate that the Earth's interior is not homogeneous but contains various structures. Among these, the most prominent are the Large Low-Shear-Velocity Provinces (LLSVPs), anomalous mantle domains extending over more than a thousand kilometers. The origin of LLSVPs is uncertain, but one hypothesis is that they formed from radiogenic heating produced by enrichment of...
Fifteen years of the Fermi Large Area Telescope (LAT) data in the halo region of the Milky Way (MW) are analyzed to search for gamma rays from dark matter annihilation. Gamma-ray maps within the region of interest (|l| < 60 deg, 10 deg < |b| < 60 deg) are modeled using known components plus a halo-like component. A statistically significant halo-like excess is found with a spectral peak around...
Strong constraints from direct detection experiments have motivated growing interest in sub-GeV dark matter. Although such light dark matter cannot be detected in ordinary direct detection experiments, it becomes detectable if it is boosted by an external mechanism, making directional information especially valuable. In many scenarios, boosted dark matter shows characteristic arrival...
