Postdoc researcher and PhD student positions in Astroparticle Physics

The Department of Astroparticle Physics invites applications for one Postdoctoral research position and one PhD position to start at the beginning of 2024.

The main objective of the work of the successful candidates will be the determination of the mass composition of ultra-high-energy cosmic rays (UHECRs) with reduced systematic uncertainties from the description of hadronic interactions using the data of the Pierre Auger Observatory and its upgrade AugerPrime. The objective includes an assessment of the feasibility of event-by-event determination of the mass of primary particles and the mass composition-enhanced studies of arrival directions of UHECRs using the data from the surface detector of AugerPrime. In this regard, studies of the properties of a muonic component of extensive air showers constitute an essential part of the work.

What you will do:

Participate in the work of the largest cosmic-ray observatory. Work in a team of experienced experimental physicists, including three coordinators of the Pierre Auger Observatory tasks Develop data-analysis techniques Improve or develop new air-shower reconstruction methods Produce air-shower simulation libraries using farm and grid computing Present results within the Pierre Auger Collaboration and at international conferences Publish your research in refereed journals Required qualifications:

Master's degree for the PhD position / PhD degree for the postdoctoral position in (astro)particle physics or astrophysics Experience with data analysis in experimental (astro)particle physics Proficiency in programming and computing (C++, python, bash, ROOT) Experience with Monte Carlo simulations using farm and grid resources is an advantage Good skills in machine learning techniques are an advantage Creative thinking and proactive problem-solving Good knowledge of English (written and spoken) What we can offer:

Interesting work in astroparticle physics field connecting phenomenology and experiment Working in the international environment of large collaboration Participation in multidisciplinary scientific projects Working in an international team and a stimulating environment Access to powerful computing (~10000 CPUs) and storage (~ 1 Petabyte) resources of the local farm and to grid computing via Virtual Organization Auger Training and development (seminars, workshops, conferences, high-quality language courses, soft skills training) A competitive salary Support of your work-life balance – flexible work hours, work from home Multisport card, meal allowance, 25 days of vacation + 6 days of personal leave/year and other benefits More information is available at: Why FZU? Terms of employment - Postdoctoral researcher:
