Astroparticles, Astrophysics and Cosmology (A2C)
Location of the proposed internship IJCLab – “Astroparticles, Astrophysics and Cosmology” pole – Gravitational Waves group Description Context: Three-mirror optical cavities exhibit properties very different from usual two-mirror Fabry-Perot cavities.…
Location of the proposed internship IJCLab – “Astroparticles, Astrophysics and Cosmology” pole – Gravitational Waves group Description Ground-based gravitational-wave (GW) detectors use kilometre-long Michelson interferometers to detect relative GW strain…

Thesis description In April 2024, the Simons Observatory’s (SO) [1] large aperture telescope will obtain its first light. This telescope, equipped with a 6m primary mirror and a focal plane…
Proposal Ground-based detectors have been directly detecting gravitational waves since 2015. Their outstanding performances are allowed by improvement with respect to the basic operating principle of the Michelson interferometer. Suspended…
Supervisors Julien Peloton: <peloton@ijclab.in2p3.fr> Jonathan Biteau: <biteau@in2p3.fr> Proposal A blazar is an active galactic nucleus (AGN) whose relativistic jet is directed nearly along the line of sight. This jet emits…
4D mapping of blazars: from optical to ɣ-ray emission 4D mapping of blazars:from optical to ɣ-ray emission 4D mapping of blazars: from optical to ɣ-ray emission 4D mapping of blazars:…
We present constraints on cosmological parameters using maps from the last Planck data release (PR4). In particular, we detail an upgraded version of the cosmic microwave background likelihood, HiLLiPoP, based…
ABSTRACT: GRB 230812B is a bright and relatively nearby (z=0.36) long gamma-ray burst that has generated significant interest in the community and therefore has been subsequently observed over the entire…
We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate events identified during the third observing run of…
