<p><b>Título:</b> Postdoc position in Low Surface Brightness science and Euclid (GEELSBE2 project)<br>
<br>

<br>

<br>
<b>descripción:</b> <o:p></o:p></p>
<p>Dear colleagues,<o:p></o:p></p>
<p>we are offering a two-year postdoc position at the University of Valladolid (UVa, Spain) and its Laboratory of Disruptive Interdisciplinary Science (<a href="https://ladis.uva.es/">https://ladis.uva.es/</a>) funded by the “Galactic Edges and Euclid in the
Low Surface Brightness Era 2 (GEELSBE2)" project (ref. no. PID2023-150393NB-I00) by the Spanish Ministry of Science & Innovation (PI: F. Buitrago & B. Sahelices). The selected candidate's work will consist in the development of Machine Learning algorithms
to detect Low Surface Brightness distant galaxy features, paying special attention to the truncations/galaxy edges in Euclid data (and its simulations) and other ultradeep data (HST, JWST). They will also have 30% of their time free to conduct any previous
research projects. Due to the scientific objectives to be achieved, a strong profile on Machine Learning will be preferred --see conditions in the provided links, where also the necessary documentation is detailed: passport copy, CV, publication list, etc.--
and thus not only people with an Astrophysics background are encouraged to apply but also more technical profiles. The University of Valladolid actively seeks a diverse applicant pool and encourages candidates of all backgrounds to apply. Please mind that,
according to the University regulations, if your PhD was not undertaken in Spain, you must also apply for the official recognition (<a href="https://www.uva.es/export/sites/uva/2.estudios/2.08.homologaciondetitulo/">https://www.uva.es/export/sites/uva/2.estudios/2.08.homologaciondetitulo/</a>)
and attached this certificate to the application.<o:p></o:p></p>
<p>The successful candidate will undertake their work on F. Buitrago's group and will benefit from all his national/international collaborations (Euclid's Local Universe --where the PI leads the Diffuse Light Working Package-- and Galaxy Evolution working packages,
Low Surface Brightness collaborations with IFCA, ICE, etc., ARRAKIHS and others like MOONS and 4HS). A strong interaction with the UVa Computer Science department and the UVa Mathematical Physics group are also expected. Both departments have a very nice
working atmosphere and conduct regular seminars, giving also the opportunity to supervise BSc and MSc students. Valladolid is a large and lively city at an hour's distance from Madrid. It is located at the center of the Castille region, and thus with plenty
of monumental places and astounding nature nearby.<o:p></o:p></p>
<p>The salary will be 42.100€ euros/year before taxes (12 pays per year) and the contract duration is expected to be approximately 23 months (February 1st 2026 to --at least-- 31st August 2027, although we will push ask for an extension until the end of 2027
and the exact dates are negotiable). In addition to the salary, the successful person appointed as postdoctoral research associate will also receive full Spanish Healthcare social benefits (e.g. medical insurance and parental leave) and an end-of-contract
payment of approximately 2.300€. They will make use of the UVa machine-learning computer facilities (and several dedicated server with powerful graphic cards). Do not hesitate to put in contact (<a href="mailto:fbuitrago@uva.es">fbuitrago@uva.es</a>) in case
you have any questions (or problems with the documentation in Spanish). Please also provide two reference letters --sent directly by the reference researchers-- to the aforementioned email address. The deadline for sending the documentation via the UVa system
is December 31st 2025, after which a selection of applicants will be made followed by interviews to those in the short list.<o:p></o:p></p>
<p>Thank you very much for your attention,<o:p></o:p></p>
<p>Fernando Buitrago<o:p></o:p></p>
<p>ps. University links with all the conditions and details (in Spanish, let us know if you need any help):<o:p></o:p></p>
