Imaging performance above 150 keV of the wide field monitor on board the ASTENA concept mission
Lisa Ferro, Leo Cavazzini, Miguel Moita +10
A new detection system for X-/Gamma-ray broad energy passband detectors for astronomy has been developed. This system is based on Silicon Drift Detectors (SDDs) coupled with scinti…
The TRILL project: increasing the technological readiness of Laue lenses
Lisa Ferro, Enrico Virgilli, Miguel Moita +16
Hard X-/soft Gamma-ray astronomy (> 100 keV) is a crucial field for the study of important astrophysical phenomena such as the 511 keV positron annihilation line in the Galactic ce…
A persistent excess of galaxy-galaxy strong lensing observed in galaxy clusters
Massimo Meneghetti, Weiguang Cui, Elena Rasia +18
Previous studies have revealed that the estimated probability of galaxy-galaxy strong lensing in observed galaxy clusters exceeds the expectations from the Cold Dark Matter cos…
Measurement of the non-linearity in the gamma-ray response of the GAGG:Ce inorganic scintillator
R. Campana, C. Evola, C. Labanti +6
A characteristic of every inorganic scintillator crystal is its light yield, i.e., the amount of emitted scintillation photons per unit of energy deposited in the crystal. Light yi…
The puzzling properties of the MACS1149-JD1 galaxy at z=9.11
Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +6
We analyze new JWST NIRCam and NIRSpec data on the redshift 9.11 galaxy MACS1149-JD1. Our NIRCam imaging data reveal that JD1 comprises three spatially distinct components. Our spe…
CLASH-VLT: The inner slope of the MACS J1206.2-0847 dark matter density profile
A. Biviano, L. Pizzuti, A. Mercurio +7
The inner slope (gammadm) of the dark matter (DM) density profile of cosmological halos carries information about the properties of DM and/or baryonic processes affecting the halo…
