Constraining primordial curvature perturbations with present and future GW detectors / Pieroni, Mauro (Madrid, Inst. Estructura Materia ; CERN)
Primordial scalar curvature perturbations ($\zeta$), typically probed on large cosmological scales via CMB and LSS observations, can be significantly enhanced on smaller scales by various early Universe mechanisms, for instance, non-minimal inflationary models. [...]

Operation of the Trigger System for the ICARUS Detector at Fermilab / ICARUS Collaboration
The ICARUS liquid argon TPC detector is taking data on the Booster (BNB) and Main Injector (NuMI) Neutrino beam lines at Fermilab with a trigger system based on the scintillation light produced by charged particles in coincidence with the proton beam extraction from the accelerators. [...]

Extreme Blazars Observed with MAGIC: Second Catalog Release / Foffano, Luca (CERN) /RE23/CTA-LST Collaboration
Extremely high-peaked BL Lac objects - also named extreme blazars - are among the most energetic and persistent extragalactic accelerators in the Universe. These sources are defined by a synchrotron emission peaking above 1017 Hz (∼ 0.3 keV) in the X-ray band [...]
