This project is connected to the PhD thesis described here. During the M2 internship, the student will develop the first part of this new HESS analysis strategy: the AI filter called FiBER (Filter Before Event Reconstruction).
The University of Paris Cité calls for applications for a PhD position in Data Intensive Astroparticle Physics to work under the supervision of Prof. Yvonne Becherini.
Super-massive black holes are known to dwell at the center of galaxies. When accreting matter they are observed from Earth as active galactic nuclei (AGNs). In a minority of AGNs the accretion of matter onto the black-hole is associated with the ejection of a relativistic jet of plasma along the polar axis.
When the black-hole's jet points right in the direction of the Earth, relativistic effects boost the emission and make these objects among the brightest in the Universe. This peculiar AGNs are called blazars.
One of the main current efforts in high-energy astrophysics and astroparticle physics is the development of multi-messenger astronomy, aiming at studying the universe and exploring fundamental physics through four complementary channels: photons, neutrinos, gravitational waves and cosmic rays.
Increasing the number of sensitive pixels in an instrument is a classical way to improve its observational capabilities. From cosmology, in the millimeter wave range, to high-energy astrophysics space instruments, the readout of thousands of cryogenic detectors requires dedicated electronic developments. Application-specific integrated circuits - ASICs offer major advantages in this context : specific design, small size and optimized performances.
