Employment Opportunities

CTA is a global endeavour to build the world’s largest and most sensitive high-energy gamma-ray observatory, which is expected to cost in the region of €300 million for equipment and an additional 1,500 person-years of effort. Imminent site preparations and construction of CTA’s first telescopes have prompted a significant recruiting effort.


The project office is responsible for the functions of general project management, technical coordination and system integration for the CTA construction project. While most positions will be located in Bologna, some will be located on the CTA sites in Chile and La Palma.

CTA Consortium Positions

The Institute for Astro- and Particle Physics invites applications for the position of a Senior Scientist in the field of observational high-energy astrophysics/astroparticle physics. The candidate should be profoundly familiar with analysis- and interpretation of data from one or more contemporary high-energy gamma-ray observatories. The institute is presently involved in the Fermi Gamma-ray Space Telescope, the H.E.S.S. telescope array, and the CTA Observatory.


We offer the opportunity to pursue a rigorous research program using foremost capable instruments in high-energy gamma-ray astrophysics, as well as to prepare for data taking and scientific investigations comprising the upcoming CTA Observatory. The successful candidate will be involved in the development, adaption and performance optimization of analysis tools for CTA-MST cameras as well as in the development and documentation of high-level analysis software for application in very-high-energy gamma-ray astrophysics. Data are to be analyzed in close collaboration with the respective instrument/scientist consortium. The successful candidate has the opportunity to lead initiatives or participate in data reduction, broadband modeling, and scientific interpretation of emission phenomena in the gamma-ray astrophysics domain.


The Appointment will be made for four years and evaluated for tenure. A Senior Scientist is expected to participate in the faculties teaching and lab activities at the level of 4 teaching hours per week. Salary and benefits are in accordance with the Austrian university law (UG 2002).

A starting date in August 2020 is anticipated.



PhD in astrophysics, preferably high-energy astrophysics or astroparticle physics.


Applications exclusively through the career portal of Innsbruck University, Code MIP-11329, – including letter of application, CV, academic record, publication list or ResearcherID/ORCID, and the names of up to three persons who will be able to provide an expert opinion about the applicant – should arrive before July 11, 2020.

  • Design, test and implement telescope control software
  • Support the commissioning and performance verification of the first telescopes on the observatory site
  • Analysis of gamma-ray telescope data



  • PhD in physics or astronomy
  • Experience with the operation of telescopes / detectors and the development of software for readout, control and/or monitoring
  • lnterest in software design, development and management
  • Knowledge of 00 programming (C++ or Java) and scripting languages (ideally python)
  • Experience in astroparticle-physics and data analysis
  • Fluent in English


For further information please contact Markus Garczarczyk +49 337627 7266, or Ullrich Schwanke +49 30 20937671,


The position is limited to 2 years.


Salary and benefits are commensurate with those of public service organisations in Germany. Classification is based upon qualifications and assigned duties.

The H.E.S.S./CTA team at LPNHE is involved in data analysis of the H.E.S.S. experiment, and notably in the study of the high energy emission from extragalactic sources, such as active galactic nuclei (AGN), and of their variability. The team participates in campaigns of target of opportunity (ToO) observations and in multi-wavelength monitoring duties to trigger such ToO campaigns. The group is also involved in the search for a potential violation of Lorentz invariance by using data from variable AGN, gamma-ray bursts – recently detected at very high energies – and pulsars. These studies are performed by comparing the photon arrival times to search for energy-dependent temporal delays. The group is particularly active on this subject within a working group which brings together the three major ground-based gamma-ray astronomy experiments, H.E.S.S., MAGIC and VERITAS.

Our activities also include the characterization of the H.E.S.S. instrument response, notably to account for the new, upgraded cameras (H.E.S.S. 1U and NamCam). The needed simulations are essential for any subsequent data analysis.

Likewise, the team is involved in the construction of CTA, the future very high energy observatory, with the development of fast acquiring electronic boards (front-end boards, FEB) which equip NectarCAM, one of the two design concepts proposed for the medium-sized telescopes (MST) of CTA. The FEB is responsible for the low level trigger and data acquisition of NectarCAM. A qualification model of NectarCAM has been built, tested in laboratory as well as during an observation campaign in spring 2019. The team is involved in the calibration of NectarCAM and in the preparation of corresponding analysis tools.
