The IAC (Tenerife) announces ONE postdoctoral contract to work in the project “Polarized Radiation Diagnostics for Exploring the Magnetism of the Outer Solar Atmosphere” (POLMAG), funded by the Advanced Grant that the European Research Council (ERC) awarded to Prof. Javier Trujillo Bueno (see

The IAC is a Public Consortium and a Severo Ochoa Center of Excellence doing research on the following areas of astrophysics: solar physics, planetary systems, stellar and interstellar physics, galactic formation and evolution, cosmology and astroparticles, as well as on development of instrumentation. Further information about the IAC's research programme is available at The appointed candidate will benefit from the research environment at the IAC, which hosts one of the largest and most active Solar Physics groups in Europe. The group covers theory, numerical modeling, observations and instrumental development, and is seriously involved in novel international projects such as the European Solar Telescope (EST) and the CLASP (Chromospheric LAyer SpectroPolarimeter) suborbital space experiments.

Duties: The selected candidate will have the following roles and responsibilities:

  • To develop advanced radiative transfer codes for computing the intensity and polarization of spectral lines, taking into account partial frequency redistribution (PRD) phenomena, J-state interference and the joint action of the Hanle and Zeeman effects in realistic atomic models including the hyperfine structure.
  • To apply such codes for planning and interpreting high-sensitivity spectropolarimetric observations with the present most advanced solar telescopes, such as the DKI Solar Telescope.
  • To contribute to the development of the “Polarized Radiation Diagnostics Website”, in collaboration with the PI and the other POLMAG scientists.
  • To contribute to the theoretical developments planned for the success of the CLASP3 suborbital space experiment, as well as with the representation of the IAC team at the international level.
  • To co-advise a PhD thesis, provided that a Resident Astrophysicist is available for carrying out his/her thesis within the framework of the POLMAG project.
  • To work on the development of the POLMAG theoretical and observational research activities
  • To help the PI with the elaboration of reports of progress to the financing entity, in coordination with the personnel involved in the project management.
  • To contribute to the public outreach activities of the POLMAG project.

Requirements: The candidates must have an excellent research record, commensurate with the duration of their research career. They must be in possession of a Ph.D. degree in Astrophysics or Physics by the application deadline (October 15, 2020): candidates that have not received their doctorate before the deadline will be not be admitted to the selection process. The IAC is an equal-opportunity employer. We encourage, in particular, applications by women and by members of minorities.

Selection process: The selection process consists of two phases: merit assessment and interview.

1. First phase: merit assessment. The Selection Panel will verify and rate the merits documented by the applicants. The maximum score that can be awarded in this phase is 80 points, calculated as the sum of the scores obtained in each of the following two sections.

a)  CV (maximum score: 60 points). Main criteria will be:

  • Scientific and technical contributions to the research field of the project, especially those listed in the Science Citation Index, in relation to the duration of the candidate’s scientific career. Of especial importance are the first-authored papers by the candidate.
  • Appointments and stays (at the PhD or postdoctoral level) in prestigious research institutions.
  • Conference contributions, especially those leading to publications.
  • Other indicators of research activity and motivation, like invitations to lectures, organization of meetings, and teaching at University level.
  • Any periods of inactivity for medical reasons, maternity/paternity leaves, elderly care, or due to training or professional experience in other fields will be taken into account.

b)  Adequacy to the objectives of the contract (maximum score 20 points)

Adequacy of the candidate’s training and experience to this contract.

  • The quantum theory of spectral line polarization.
  • The generation and transfer of polarized radiation taking into account J-state interference and PRD phenomena in complex atomic models, including the hyperfine structure.
  • Development and coding of numerical methods for realistic radiative transfer simulations.
  • Realistic numerical modeling of the polarization produced by optical pumping and the Hanle and Zeeman effects in spectral lines, with emphasis on the Na I D1 and D2 lines.

The candidates must have undertaken novel research developments and hold promise to become a leading researcher in the field of solar physics in the coming years.

Form of accreditation for both sections: A report of the candidate's technical and research activity, accompanied by documentation accrediting the activities mentioned.

2) Second phase: interview. (maximum score 20 points)

  • Candidates that have obtained at least 50 points in the first phase will be invited to an interview. The interview may be given in either Spanish or English (as chosen by the candidate) and take place either in person at the IAC headquarters or using internet communication software (Zoom) that allows voice and image transmission.
  • During the interview, the candidate will present, for a maximum of 10 minutes, his/her vision about the suitability of his/her professional profile to the position and the planned research activity if awarded the contract. The presentation may be followed by questions by the Selection Committee.

Of the maximum 20 points to be awarded:

  • Up to 10 points correspond to the suitability of the candidate’s profile to the position
  • Up to 10 points correspond to the candidate's vision for their future research activity.

To pass the second phase a minimum score of 15 points will be necessary.

To pass the selective process, a minimum of 65 points must be reached. If there is a draw in the score of two or more candidates, priorities will be set according to the Equality Plan of the IAC.

Training: Candidates who obtained their doctorate at the IAC must provide accreditation of a period of complementary training at other research centres. The required period is a full continuous year or 18 accumulated months (including periods of training during doctoral studies).

Duration: The appointment will be for a period of three years, subject to annual revisions. The estimated date of commencement will be January, 2021.

Remuneration: The gross annual salary will be 43.374 Euros, with deductions of up to 20% for income tax (IRPF) and social security (dependent on the candidate's personal situation). The contract provides social security cover for spouse or de facto partner and children.

Research travel funds: The contract includes all the travel expenses needed for the successful development of the project (conferences, workshops, observing runs, collaboration stays, etc.).

Extra financial support to start the contract: The present job offer includes financial support for the selected candidate at the time of starting the appointment. The support covers the following items: air ticket (arranged by the IAC), stay at a hotel for a maximum of two weeks (reservation made by the IAC), and a per diem rate for a maximum of two weeks. This financial support cannot exceed 2,500 Euros.

Applicants from outside the EU: Successful applicants who are not citizens of a member country of the European Union must keep in mind that, prior to signing the contract, they must obtain a residence and work permit (NIE card) from the Spanish immigration authorities.

Presentation of applications: Applications must be sent electronically via the web-based application system before the deadline set out in this advertisement. Alternatively, you may follow the instructions given in the corresponding official advertisement on our website.

The following documentation must be sent in a single PDF file:

  • Application form (Annex I, duly filled in and signed, including the position title and code number of the job offer)
  • Copy of passport or national identity card (with the same number indicated in Annex I).
  • CV, containing a list of publications
  • Report on research activity and justification of suitability for the job (not exceeding 2 pages)

The IAC, welcomes and supports the Recommendation of the European Commission 2005/251/EC of March 11th 2005 on “The European Charter for Researchers” and “The Code of Conduct for the Recruitment of Researchers” adopted by the European Commission. Both documents are nowadays key elements of the European Union policy for making research an attractive career and stimulating economic growth and employment in Europe.

During 2017, IAC has made a deep analysis about the "HR Strategy for Researchers" (HRS4R) fostered by the European Commission and its possible implementation at the IAC. HRS4R is a mechanism to support the implementation of the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers (C&C).

The outcome of that process is a GAP-Analysis and Action Plan for 2018-2019. After this process, the IAC has been awarded the "HR Excellence in Research" logo and recognition by the European Commission. We are now in the Implementation Phase of the Action Plan.

Application deadline: OCTOBER 15, 2020
