Study of blazar variability through their flux distribution for CTAO long-term monitoring

A. Mikhno, J. Biteau, J. -P. Lenain on behalf of the CTAO collaboration

The CTAO Key Science Project on Active Galactic Nuclei (AGN) includes a long-term monitoring (LTM) program of blazars. The probability distribution function (PDF) of the flux extra…

Impact of uncertainties on the cosmic optical and infrared backgrounds on the propagation of astroparticles

Lucas Gréaux, Antonio Condorelli, Leonel Morejon +2

When propagating through the universe, gamma rays at very-high energy (VHE, E > 100 GeV) and ultra-high energy cosmic rays (UHECRs, E > 1 EeV) can interact with the optical, infrar…

CtaAgnVar : a Pipeline for Variability Studies with the Cherenkov Telescope Array Observatory

G. Grolleron, J. -P. Lenain, J. Biteau +2

Blazars are active galactic nuclei whose relativistic jet points toward the observer, accelerating particles that radiate across the electromagnetic spectrum. Characterizing their…

Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346

Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…

Search for active-sterile neutrino transitions using Pierre Auger Observatory data

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +348

We investigate the sensitivity of the Pierre Auger Observatory to physics beyond the Standard Model arising from magnetic-moment-induced transitions between active and heavy steril…

Proton-air interaction properties at TeV from shower-depth measurements with the Pierre Auger Observatory and their connection to the Muon Puzzle

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +347

Hybrid measurements at the Pierre Auger Observatory indicate that most high-energy hadronic interaction models underestimate the average depth of the shower maximum, $\langle X_{\m…
