PostDoctoral researcher
Multi-messenger transients with Astro-COLIBRI
As part of the “Multi-messenger Observations of the Transient Sky” (MOTS) project, backed by the French National Research Agency, the successful candidate will participate in the development of Astro-COLIBRI, a novel software framework that provides easy access to information about multi-wavelength and multi-messenger transient phenomena. The role also offers the opportunity to contribute to the science program of the H.E.S.S. and CTA/LST VHE gamma-ray observatories, the SVOM mission and to exploit other multi-wavelength or multi-messenger opportunities.
Prospective candidates must hold a PhD in astroparticle physics or astrophysics, with a pronounced interest in software development, experimental data interpretation, and physics analysis. Proficiency in Python is essential, and experience in web or app development is advantageous. We, a dynamic and international team, are particularly keen on increasing female representation in our field and strongly support applications from women in our quest for diversity, excellence, and innovation.
The two-year position begins in mid-2024, with funds allocated for conference travel and equipment. The search will continue until the right candidates are selected. However, we strongly encourage interested applicants to submit their applications by mid-March 2024 to be considered in the initial round of evaluations.
Please submit the following to Fabian Schüssler at fabian.schussler@cea.fr and refer to the Postdoc Application Guidelines for further details:

PhD thesis
High-energy transient astrophysical phenomena
The core of the proposed thesis project will be the real-time search for transient high-energy emission linked to the detection of a gravitational waves and other multi-messenger astrophysical transients like high-energy neutrinos, gamma-ray bursts, fast radio bursts, stellar/nova explosions, etc. The combined observations across multiple instruments and cosmic messengers will unequivocally prove the existence of a high-energy particle accelerators related to these phenomena and will allow to derive novel insights into the most violent explosions in the universe.
Joining the H.E.S.S., CTA and SVOM collaborations the PhD candidate will be able to lead the exciting MWL and multi-messenger campaigns collected during the physics run O4 of the GW interferometers, the first high-energy neutrino events detected by KM3NeT and the first GRBs detected by the SVOM satellite. The PhD candidate will also have the opportunity to participate in the development of the Astro-COLIBRI platform allowing to follow transient phenomena in real-time via smartphone applications.

Atilla Kaan AlkanInternship M2 (2020) + PhD (since 2021)During his internship Atilla worked on natural language processing of reports of astrophysical observations. He implemented his own version of a Word2Vec vector representation of GCN circulars. Atilla also joined the Astro-COLIBRI development team and improved the assessment of the observability of a source for ground based observatories.
Atilla is doing a joint thesis with experts from the LISN institute at the Paris-Saclay university. He will be implementing an artificial intelligence based pipeline to process reports on astrophysical observations (e.g. ATELs, GCN circulars, TNS astronotes, etc.). Using tools for natural language processing (NLP) the results will help to improve the Astro-COLIBRI platform. |

Patrick ReichherzerPhD (2019-2022) + collaborator (since 2022)Patrick did a joint PhD program between the university Paris-Saclay and the Ruhr-Universität Bochum (RUB). He started his PhD work at RUB under the supervision of Prof. J. Tjus on modelling of the diffusion of cosmic rays in highly turbulent magnetic environments. During his stay at IRFU in 2020 he worked mainly on studies of VHE emission of AGNs with H.E.S.S. and the Astro-COLIBRI transient tool. Patrick graduated from RUB and the university Paris-Saclay in 2022. Since then he is participating in the group activities as external collaborator.

Valentin LefrancPostdoctoral researcher (2021-2023)Valentin was leading the development of the Astro-COLIBRI transient tool. After a PhD thesis in our group at IRFU/CEA and Desy-Zeuthen (Berlin, Germany) he was developing Machine Learning tools as freelance software developer and for different start-ups before joining us again for a postdoctoral position.

Anke YusafzaiInternship M2 (2019)During her internship Anke started to develop Astro-COLIBRI, a novel framework summarizing stable and (most importantly) transient phenomena. Using data from a number of catalogs and the VoEventDB, Astro-COLIBRI provides easy access to what is going on in a given patch of the sky and thus enables, facilitates and improves dedicated follow-up observations of multi-messenger transients.
Anke is currently pursuing a PhD at ECAP/University of Erlangen (Germany). |

Halim AshkarInternship M2 (2018) + PhD (2018-2021)During his internship Halim analyzed the H.E.S.S. observations obtained after the detection of gravitational waves from the binary black hole merger GW170814. As expected, no high-energy gamma-ray emission was found and limits on the full localisation region of the event could be derived.
During his PhD Halim was focussing on the study of multi-messenger transients at very-high energies. He is mainly searching for VHE gamma-ray counterparts to gravitational waves and Fast Radio Bursts with H.E.S.S. and CTA. See for example here. Halim is currently working as postdoctoral research at LLR/Palaiseau. |

Monica Seglar-ArroyoInternship M2 (2016) + PhD (2016-2019)During her internship Monica developed a detailed, time dependent model of the atmosphere above the H.E.S.S. observatory, which allowed to verify the model used in the H.E.S.S. simulations and estimate remaining systematic uncertainties.
During her PhD Monica was working on the study of multi-messenger transients, focussing mainly on searches for high-energy gamma-ray counterparts to gravitational waves with H.E.S.S./CTA and HAWC. She was also involved in the study of other transient phenomena like AGN flares with high-energy observatories. Monica spent one year at PennState (US) before finalizing her PhD at the Université Paris-Saclay in 2019. She is now a postdoctoral researcher in the Virgo collaboration at LAPP (Annecy, France). |
