| One Postdoctoral Contract Sinergia Porject 2018 | Closing date: 2019-01-08
Contact: Secretariat of the Research Division |
| The Instituto de Astrofísica de Canarias (IAC, Tenerife, Spain) invites applications for ONE advanced postdoctoral contract to work in the project ?HPC-techniques for 3D modeling of resonance line polarization with Partial Frequency Redistribution?. This research project is funded by the Swiss National Science Foundation (SNSF) within the framework of ?Sinergia?, a programme promoting interdisciplinary collaboration between two to four applicants on projects involving breakthrough research. | | ▸ more | The aim of the project is to combine competences and expertise in the fields of the generation and transfer of polarized radiation in magnetized plasmas, atomic physics, spectropolarimetry, computational sciences and high-performance computing (HPC). The goal is to develop novel accurate and robust parallel solution methods for the radiative transfer (RT) problem for polarized radiation in realistic three-dimensional (3D) models of the solar atmosphere, taking into account the effects of correlations between the incoming and outgoing photons in the scattering events (PRD effects, from partial frequency redistribution). The selected candidate will closely interact with the postdocs and scientists working on the same project at IRSOL, ICS and ASCR. Moreover, she/he will also benefit from scientific collaborations with the POLMAG group of the IAC (see http://www.iac.es/proyecto/polmag/). The position implies regular working visits to the other research centers involved in the project.
Duties: Starting from the radiative transfer code PORTA (Stepan & Trujillo Bueno 2013; A&A, 557, 143), the selected candidate is expected to work on the development and application of a novel 3D radiative transfer code for modeling, by means of massively parallel supercomputers, the spectral line polarization produced by the joint action of anisotropic radiation pumping and the Hanle and Zeeman effects in the solar atmosphere, taking PRD effects into account.
In particular, she/he will have the following responsibilities:
- To strongly contribute to the development of the above-mentioned non-LTE radiative transfer code. This implies to work with the theoretical aspects of the problem, as well as with the implementation and testing of the newly developed methods and HPC techniques.
- To apply the new code to perform forward modeling calculations of the intensity and polarization of various solar resonance lines of great interest for probing the solar chromosphere via confrontation with spectropolarimetric observations, using 3D models resulting from plasma-radiation simulations of the solar atmosphere.
- To confront the results of the new 3D radiative transfer calculations with spectropolarimetric measurements of (a) the hydrogen Lyman-alpha line observed by CLASP-1, (b) the Mg II h & k lines that CLASP-2 will hopefully observe in 2019 and (c) other chromospheric lines to be observed with ground-based telescopes (e.g., SST, GREGOR and DKIST).
- To prepare competitive supercomputing proposals for the Barcelona Supercomputing Center (BSC) and the Swiss National Supercomputing Center (CSCS).
- To interact closely with the other postdocs and scientists working at the other institutions involved in this interdisciplinary project, including regular working visits to their research centers.
- To co-advise a PhD thesis, provided that an IAC Resident Astrophysicist is available for carrying out his/her thesis within the framework of this project.
- To help with the coordination of the theoretical and numerical developments required for the success of the project, as well as with the representation of the IAC team at the international level.
- To elaborate reports of progress, justification, etc., to the SNSF, in coordination with the PIs and the personnel involved in project management.
- To contribute to the public outreach activities of the project.
Position requirements: The candidates must have undertaken novel research developments and hold promise to become a leading researcher in the coming years. Candidates with experience on numerical radiative transfer and the theory of polarization in spectral lines are especially welcomed to apply.
Qualification requirements: To be eligible for admission, applicants must have obtained a Ph.D. degree in Astrophysics or Physics, by the application deadline (January 8, 2019). A copy of the degree or corresponding stamped certificate (issued by the University where the degree was obtained) must be included. Applicants who have not completed their Ph.D. degree within the application deadline will not be considered.
Selection stage: The selection process will consist of two stages: a merit assessment phase and an interview.
Training: Those candidates who have done their Ph.D. research at the IAC must have undertaken a period of training in other research centres. This period must consist of either one continuous year or 18 accumulated months (including periods of training during their doctoral period).
Duration: The duration of the contract will extend up to September, 30th, 2022 (ending of the project), subject to annual revisions. The contract is expected to start in early 2019 (exact date to be negotiated).
Research travel funds: The contract includes all the travel expenses needed for the successful development of the project (meetings, workshops, observations, collaborations, etc.).
Remuneration: The gross annual salary will be 40.668,74 Euros, plus the annual residence allowance (2,133.96 Euros). The contract includes medical insurance under the Spanish National Health Service, which will also cover the registered partner (de facto partner) and children (if relevant).
Relocation allowance: This call includes a relocation allowance (for the appointed candidate only) comprising: the cost of the flight ticket (booked and issued by the IAC), temporary accommodation for up to two weeks (organized by the IAC) and a per diem rate up to two weeks. The allowance cannot exceed the amount of 2,500 Euros.
Non-UE citizens: Applicants who are not citizen of a country belonging to the European Union are invited to apply for this position, but, if selected, will be allowed to sign the contract with the IAC only after obtaining the compulsory documentation required to live and work in Spain.
How to apply: The required documentation must be submitted using the online application system http://www.iac.es/jobs/research/, and received by the application deadline
