About me
Hi and welcome!
I am Benjamin, a 3rd year PhD student at CEA (Commissariat à l’Énergie Atomique) in Saclay (France). I work at the Astrophysics Department (DAp) in the research group Cosmology and Evolution of Galaxies (LCEG).
I am a member of the Sino-French SVOM mission dedicated to the study of Gamma-Ray Bursts, scheduled for mid-2023. I am involved in the preparation of the science, the follow-up of the alerts and the energy calibration of the X-ray telescope (MXT) onboard the satellite.
My work and research
My main interests are the high-energy and transient phenomena, e.g. Gamma-Ray Burst (GRB), and their host galaxy. Through my thesis, I am studying the environments giving birth to long-duration Gamma-Ray Bursts. Using a sample of long GRB host galaxies observed with the Hubble Space Telescope (HST) in the infrared band, I quantify the impact of the galaxy size and density on the GRB production.
I am also interested in the follow-up observations of transient objects. I am part of the Stargate consortium in charge of triggering observations with the Very Large Telescope (VLT) in Chile based on GRB Swift alerts.
In the past years, I was involved in the characterization of the Microchannel X-ray Telescope (MXT) on board the SVOM mission. I actively participated in several test campaigns, including the science performance tests of the MXT Flight Model instrument at the Panter X-ray test facility in Munich.
Current projects
- Prediction of the expected hydrogen column density distribution of SVOM/MXT GRBs;
- Determination of the quantum efficiency (QE) and charge transfer efficiency (CTE) of the MXT Flight Spare model using data collected on the Metrology beamline of the SOLEIL synchrotron in November 2021.
