Ref0144 / Deadline: May 15th, 2026 (14:00 CEST)
Abierto / OpenOffer description
The Centro de Estudios de Física del Cosmos de Aragón (CEFCA) offers a fully funded four-year PhD position combining numerical simulations and observational studies of small Solar System bodies.
The observational component offers the chance to work with both new and archival imaging data to extract astrometric and photometric information, including identifying fast-moving objects and potential indicators of activity. The successful candidate will gain experience in developing analysis tools and selecting targets for dedicated follow-up observations, supporting both modeling efforts and the rapid characterization of high-priority Solar System objects.
The numerical component provides an opportunity to apply and extend the model simulating coupled dynamical and thermal evolution. This includes selected asteroid targets, address objects with incomplete constraints, such as missing astrometric data or spin-state information, and develop enhancements to the model using modern techniques to robustly estimate thermal properties and their uncertainties. The candidate will be supervised by Dr. Bojan Novakovic.
The PhD program structure will be determined jointly by the selected candidate and the supervisor, taking into account the candidate’s background and interests. Candidates should have a relevant background in physics, astronomy, or related fields and meet doctoral program requirements. The selection committee values strong motivation, willingness to learn new skills, and enthusiasm for the research topic. Previous experience in related fields is an advantage but not a strict requirement; comprehensive support from the supervisor and CEFCA team will be provided.
The contract will be conducted at the CEFCA’s headquarters in Teruel, Spain. The position includes salary, essential equipment, and funding for collaborations, and attendance at national and international meetings. Support will be provided to assist with relocation to Teruel, such as guidance on visa applications for international candidates, and advice on finding local housing and settling in the area.
About CEFCA
CEFCA is a research institution located in Teruel, Spain, in charge of the operation, data management and scientific exploitation of the Observatorio Astrofísico de Javalambre (OAJ), an astronomical facility specifically suited for carrying out large astronomical surveys with very large field-of-view (FoV) telescopes: the 2.5m Javalambre Survey Telescope (JST250; 3deg diameter FoV) and the 83cm Javalambre Auxiliary Survey Telescope (JAST80; 2deg diameter FoV).
JST250 is equipped with JPCam, a ~1.2Mpix panoramic camera consisting of a mosaic of 14 CCDs of ~9.2k x 9.2kpix. The JPCam/JST250 system provides a 4.1 deg2 FoV and hosts a complete new set of 54 filters of ~140A width, covering the whole optical spectral range plus two broader filters at the blue and red ends. In the coming years, JPCam/JST250 will be primarily devoted to carry out the Javalambre Physics of the accelerating Universe Astrophysical Survey (J-PAS), which will produce photo-spectra of hundreds of millions of astronomical objects with wide-ranging applications in astrophysics and cosmology.
JAST80 is equipped with the panoramic camera T80Cam, hosting one CCD identical to those in JPCam. The T80Cam/JAST80 system provides an effective FoV of 2 deg2. Since 2016, it is primarily dedicated to conducting the Javalambre Photometric Local Universe Survey (J-PLUS), whose fourth data release (~ 5000deg2) was made public in November 2025. It also carries out the Javalambre VARiability survey (J-VAR).
The OAJ is a Spanish ICTS (Unique Scientific and Technical Infrastructure). As such, CEFCA offers 20% of OAJ Open Time to competitive PI-led projects, including Legacy Surveys with JAST80.
The OAJ data are reduced, calibrated, and released by the Data Processing and Archiving Department (DPAD) at CEFCA. In addition, the data from the main CEFCA surveys, such as J-PAS and J-PLUS, are validated and scientifically exploited by members of the Research Area at CEFCA.

CEFCA is committed to promoting gender parity among its staff. Hence, applications from women are strongly welcome.
In order to strengthen objectivity in the selection process, applicants are offered the possibility of submitting a blind curriculum vitae. A blind CV is a format that deliberately avoids including information on sex, age, origin, disability, or other personal circumstances, and includes exclusively aspects related to the applicant’s education, experience, merits, and professional qualifications.
Evaluation process
The committee will first evaluate the suitability of the candidates on the basis of their CVs and reference letters. In this first stage, the evaluation criteria will be:
Criterion 1. Academic and/or scientific-technical background of the candidate (up to 50 points).
Subcriterion 1.a): Scientific-technical contributions (up to 45 points). The academic record and other curricular merits of the candidate will be evaluated, as well as their relevance to the tasks to be performed, based on their education and professional experience.
Subcriterion 1.b): Mobility and internationalization (up to 5 points). The relevance and impact of the candidate's stays at national and international institutions and/or in the industrial sector will be assessed in relation to their research trajectory, taking into account the prestige of the host institution and the activities undertaken during the stay.
Criterion 2. Suitability of the candidate for the research activities to be undertaken (up to 30 points).
The candidate's suitability for the program, project, or research activities to be carried out will be evaluated based on their prior education and experience. This will include consideration of the added value the project will bring to the candidate's research career, as well as the contribution to the host center and team.The best candidates will move to a short list for a final interview. The interview phase will add up to 20 points to the Criterion 2 above, for a maximum of 50 points at the end of the process. The position will be offered to the best candidate after the full evaluation process.
Being aware of the impact that leave and career breaks related to family life (maternity, paternity, adoption, and the care of dependent family members) may have on scientific and technical careers, these circumstances will be taken into account, together with the corresponding justification, during the evaluation process.
