Building Bridges: Towards a Unified Picture of Stellar and Black Hole Binary Accretion and Evolution

Binary systems are ubiquitous in nature, from stars to the supermassive black holes expected to reside in galactic nuclei. In many circumstances, the binary system is enveloped by circumbinary gas. How does circumbinary gas evolve and influence the embedded binary? What observational signatures of this gas are most informative? What novel numerical techniques must we deploy to better model these systems? This conference will bring together two distinct communities: those working on massive black hole binaries with those working on stellar binaries. Because recent years have seen remarkable progress in observations of stellar binaries, and numerical modeling of both stars and black holes, now is the ideal time to bring together these two groups. The conference will highlight the remarkable similarities of problems at such varied astrophysical scales, and shed light on the crucial next steps for pushing the boundaries of our knowledge.

3. POSTDOCTORAL POSITION IN EXPERIMENTAL ASTROPARTICLE PHYSICS

Applications are invited for a 2-year Postdoctoral position in Experimental Astroparticle Physics at LPNHE, to establish a pure, efficient and scalable method to detect air showers from radio signal. The work will be strongly linked to the GRAND (Giant Radio Array for Neutrino Detection) project, which aims at building a gigantic network of radio antennas, to study ultra-high energy cosmic particles, and contribute to solving the mystery of their origin. The project will be done in close collaboration with the GRAND group at the Karlsruhe Institute of Technology.

The GRAND Paris group, led by O. Martineau (LPNHE) and K. Kotera (IAP), and comprising of 3 PhDs, 2 postdocs and 3 engineers, is in charge of developing an efficient algorithm to identify and select the transient radio pulses observed at the output of the antenna, that could be induced by air showers. This first level trigger will be based on advanced signal treatments (analytical or based on Machine Learning) and implemented online on the front-end electronics board plugged at the output of the GRAND antennas.

The selected candidate will have a leading role on the experimental aspects of this project, and will have the opportunity to take an active part in the scientific analysis of the data recorded with the GRANDProto300 pathfinder, expected to be a goldmine for cosmic-ray physics.

Candidates must have a Ph.D. in physics or astrophysics, and a solid background in experimental physics and data processing. Programming skills are required, ideally in Python and C++. Experience in detector R&D, online software development and electronics will be appreciated. Candidates with few years of experience after PhD are welcome to apply.

4. PHD POSITION(S) IN ULTRA HIGH ENERGY COSMIC RAY AND NEUTRINO PHYSICS

The Astroparticle physics group in the Physics department of the Colorado School of Mines is looking to fill at least one PhD position in the areas of ultra-high energy cosmic ray and/or neutrino physics starting in the Summer 2022. The position includes all tuition costs and a stipend funded through NASA and the National Science Foundation (NSF) grants.

Job Description: The successful candidate(s) will join the Astroparticle physics group at the Colorado School of Mines, which currently consists of two faculty, two postdocs, four PhD students and several undergraduates. Their research will focus on one or both of the following projects:

Project A: As a member of the Pierre Auger Collaboration, the Mines group is leading the effort to deploy and operate an array of 8 fully out tted and upgraded Pierre Auger Observatory (Auger) surface detectors deployed at the Telescope Array (TA) in Utah. The purpose of this project is to cross-calibrate the energy scales of the Pierre Auger Observatory and the Telescope Array project using showers simultaneously measured by the TA and Auger detectors. This effort is critical as currently there are irreconcilable differences between the spectra measured by the two projects, complicating astrophysical interpretations. The PhD student joining this effort will be involved in the deployment and operation of the Auger micro-array and take the lead on the data analysis.

Project B: The Mines group is involved in a NASA project to develop the νSpaceSim simulation code. The code is targeted at supporting the development of the next generation of space-based cosmic ray and neutrino detectors by describing the development of air showers catalyzed by the atmospheric decay of tau leptons produced via the interaction of high-energy tau neutrinos inside the Earth. A first version of the code was recently released, and the Mines group will continue the work to further develop the code. A primary project is to implement the emission of fluorescence light from the air shower as currently only Cherenkov light is modeled. This will enhance the code capabilities and broaden its application to ground-based observatories as in the latter case, the observation of an upward-going shower emerging from the Earth would be an unmistakable sign of a neutrino-induced shower. Additionally, the Mines group will benchmark the code using data from a Super-Pressure Balloon experiment, which will launch from New Zealand in 2023. The PhD student joining this effort will lead the further development of the Mines contribution to the νSpaceSim code, including the analysis of relevant data from the balloon experiment.

The successful candidate will also be expected to travel internationally and present their work at conferences and in publications. Further research opportunities are possible through ongoing proposals related to the Super Pressure Balloon experiment which are currently under review. By summer 2022, we may be looking to recruit one more PhD student, whose task would be to search for the rst signature of an extensive air shower observed by uorescence from near-space.

Qualifications: Applicants must hold a degree in physics at the time of recruitment and are preferred to have experience in experimental or theoretical astroparticle physics or a closely associated field such as nuclear or particle physics. Prior experience with hardware, data analysis and/or simulation codes, as well as knowledge of modern programming languages (python, C++, etc.) will be advantageous.

Applications: Applicants should contact Prof. Fred Sarazin at Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser. as soon as possible and no later than: April 15th, 2022. Review of applications will start immediately.
