Post-doctoral position in High Energy Gamma-Ray Astrophysics with the H.E.S.S. and CTA observatories – Studies of Extreme-Energy Particle Accelerators


The candidate will join the H.E.S.S. collaboration and be involved in improving H.E.S.S. analysis pipelines using a variety of methods including machine learning, working closely with Prof. Gavin Rowell, Dr. Sabrina Einecke and also A/Prof. Martin White. Intimately related radio and X-ray astrophysical studies will also be possible with collaborator Prof. Miroslav Filipovic at Western Sydney University utilising world-leading facilities such as the ASKAP and MWA radio telescopes and the recently-launched eROSITA X-ray space mission.


The candidate will utilise the High Energy Stereoscopic System (H.E.S.S.) of gamma-ray telescopes located in Namibia to study sources of the Milky Way’s extreme-energy cosmic-ray particles known as “PeVatrons”. Recent upgrades to H.E.S.S. enable new aspects to be fully exploited (such as event timing) and promise exciting discovery potential in the next few years. H.E.S.S. leads the field of ground-based gamma-ray astronomy and has discovered the majority of astrophysical sources in this energy range.


The Cherenkov Telescope Array (CTA) is the next generation multi-national facility for ground-based gamma-ray astronomy. The University of Adelaide leads a group of six Australian institutions involved in CTA. The candidate will be able to join the Australian team developing CTA’s highest energy telescopes which are expected to produce their “first light” in the next 2 to 3 years. The candidate will thus further strengthen Australia’s contribution to CTA.

This project focus on the study of extra-galactic transient sources with the current and future generation of gamma-ray telescopes. Beyond their interest as astrophysics sources, flaring active galaxy nuclei or gamma-ray burst are very promising probes for fundamental physics (Lorentz Invariance Violation, extragalactic background light…). The observation and study of GRBs is now of prime importance in the domain. The recent detection of 3 GRBs by H.E.S.S. and MAGIC opened a new window in VHE gamma-ray astronomy. Same applies for Virgo/LIGO whose detectors is now sending regular GW alerts from various kind of binary systems.

The first CTA large telescope will be operational beginning of 2020 and will bring additional detection capabilities in the VHE gamma-ray domain. The project consists in participating in the commissioning and early science of the first LST, in the first CTA alert follow-up, while contributing actively in the data analysis already collected by H.E.S.S..

The project aims to strengthen the collaboration in between the Virgo and Astro-gamma groups. It will consist in optimizing the treatment of alerts received from Virgo/LIGO and participate to the joint data interpretation in case of successful follow-up.



1) The successful candidate will take part in the data analysis of the second phase of the H.E.S.S. experiment. The candidate will also be expert-on-duty for H.E.S.S. regarding the GRBs follow-up. The data analysis results and consequent interpretation will be discussed in a multi-wavelengths and multi-messengers approach through the combination of the Fermi-LAT data (Analysis expert are present at LAPP), public optical and X-ray data. X-ray data analysis expertise is appreciate.

2) The first observations and alert follow-up with the first LST will start mid of 2020. The candidate will take part of the commissioning of the telescope and assume a leading role in the analysis of the first data and the very first alert follow-up.

3) CTA will re-act to alert sent by different instruments: X-ray and Gamma-ray telescopes, Neutrino telescopes and also Gravitational waves (GW) alerts from Virgo/Ligo. In particular, the candidate will work with the Virgo group to optimise the alert follow-up strategy. In case of successful follow-up of a GW alert, the candidate will assume a leading role in the discussion in between the 2 Collaborations.



Due to the multiple and ambitious aspects of this project, the successful applicant should already count on a solid background in high-energy astroparticle physics. A background in GW data analysis will be a plus.

The successful applicant will be able to start working as soon as he/she arrived based on a solid background of the groups and in return contribute in the LAPP groups as well as in the H.E.S.S. Extragalactic “working group” and CTA “physic group”. The time scale of the project fits particularly well within the schedule of the two experiments involved. A large set of data have been already collected and not fully analyzed by the H.E.S.S. collaboration and allows to start immediately an analysis activity. In parallel, the effort done in the H.E.S.S. context will be transferred to the CTA case in order to prepare the analysis of the very first observations with the LST prototype starting beginning of 2020.
