2 to 3-Year Postdoctoral Appointment on extragalactic mm-wavelength surveys, CAB CSIC-INTA Spain
Postdoctoral Research Assistant
(1 position, fixed term)
Salary: 39,000-43,000 euro gross/year, depending on experience
Benefits: Social benefits as mandated by Spanish labor law
The Department of Astrophysics at the Center for Astrobiology (CAB CSIC-INTA, Spain https://cab.inta-csic.es/en/) invites applications for a postdoctoral research assistant position in the field of Galaxy Formation and Evolution. The successful candidate will work on the Milgatz project (ATR2024-154316, http://www.itziararetxaga.net/2025/06/atrae-milgatz-project/), led by Dr. Itziar Aretxaga, entitled: "Millimeter-Wavelength Large-Area Surveys of Galaxies with TolTEC at High Redshift (Milgatz)"
The selected candidate will join the CAB campus in Villafranca del Castillo, located at the European Space Astronomy Centre (ESAC, https://www.esa.int/About_Us/ESAC), near Madrid. The position is expected to start between June and September 2026.
CAB is a multidisciplinary research institute jointly funded by the Spanish National Research Council (CSIC) and the Spanish National Institute of Aerospace Technology (INTA). It operates across two campuses: ESAC (Villafranca del Castillo) and INTA (Torrejón de Ardoz). The successful candidate is expected to interact with researchers at both campuses and with the international TolTEC science team.
As a member of the Spanish research community, the successful candidate will have access to major observational facilities, including ESO facilities (VLT, ALMA), IRAM/NOEMA, and observatories at La Palma, such as the 10.4 m Gran Telescopio Canarias (GTC) and ING, with access to the Large Millimeter Telescope (LMT).
Project Description
Milgatz exploits millimeter-wavelength surveys conducted with the TolTEC camera (http://toltec.astro.umass.edu/) at 1.1, 1.4, and 2.0 mm on the Large Millimeter Telescope Alfonso Serrano (LMT). The project aims to characterize the dusty star-forming galaxy population and quantify its contribution to the star formation history and chemical enrichment of the Universe. The successful candidate will be part of the TolTEC-associated science team, with direct access to TolTEC Legacy Survey data.
Requirements
Applicants should:
- Hold a PhD in Astronomy or Astrophysics by June 2026
- Have experience in observational extragalactic research
- Demonstrate a strong publication record in peer-reviewed astronomy journals
- Possess high-performance computing skills and/or millimeter-wavelength observational experience
Experience with extragalactic surveys at optical, infrared, millimeter, and/or radio wavelengths will be particularly valued. Teaching experience, student supervision, outreach activities, and knowledge of Spanish are considered assets but are not required.
Research Group
Dr. Itziar Aretxaga is the project scientist of TolTEC and joined CAB in 2025 with the Milgatz project. The TolTEC scientific collaboration comprises more than 70 scientists across 8 countries. The selected candidate will join the TolTEC scientific associates team and interact closely with this international consortium, as well as with the Galaxy Formation and Evolution research group at CAB (Villafranca del Castillo and Torrejón de Ardoz).
Application Procedure
Applicants should submit the following materials by April 1, 2026:
- A curriculum vitae (maximum 2 pages)
- A publication list, highlighting up to five key contributions and briefly describing the applicant?s role in each
- A statement of past research accomplishments and current research interests (maximum 3 pages, plus references)
Applicants should also arrange for two to three letters of recommendation to be sent directly to:
Dr. Itziar Aretxaga
Email: iaretxaga @ cab.inta-csic.es
Diversity Statement
Milgatz and CAB are committed to diversity and equal opportunity, and do not discriminate on the basis of gender, ethnicity, age, or socioeconomic background. We strongly encourage all qualified candidates to apply and to consider joining our team.

Título: PD Time domain astrophysics GOTO 2026. PS-2026-006
Centro: Instituto de Astrofísica de Canarias
Tipo: Postdoctoral
descripción:
The IAC (Tenerife) invites applications for ONE postdoctoral contract to work on the project linked to the line of research “Black holes, neutron stars, white dwarfs and their local environment”. The contract is funded by the project “GOTO”, led by Drs. Jorge Casares, Josefa Becerra and Manuel Pérez Torres in collaboration with the University of Warwick (https://goto-observatory.org/).
Research topics at the IAC include most areas of astrophysics: Solar Physics (FS), Exoplanetary System and Solar System (SEYSS), Stellar and Interstellar Physics (FEEI), The Milky Way and The Local Group (MWLG), Formation and Evolution of Galaxies (FYEG), and Cosmology and Astroparticles (CYA-CTA). All of these are supported by an ambitious instrumentation programme. Further information about the IAC's research programme, its Observatories and the 10.4m GTC is available at the IAC's web page: https://www.iac.es/en
Tasks:The successful candidate will pursue research in the following fields:
- Multi-messenger follow-up (gravitational waves, neutrinos), and/or another research activity directly related to the complimentary exploitation of the GOTO photometric database. In particular the candidate will undertake multi-wavelength follow-up and time-domain studies of GOTO transients. A key requirement of the candidate will be the successful exploitation of GOTO for Mini-HAWKs sources during its operation time.
- The candidate will serve as liaison for IAC researchers interested in exploiting the GOTO database for non-GW purposes. In particular, helping with querying the database and solving access issues to possible users.
- The candidate is expected to participate and coordinate follow-up observations of GOTO with other IAC projects related to GW/transient events. This includes the MAGIC and LST telescopes (also CTAO in the future), observing programs allocated to IAC researchers for GW science, LSST, and other time-domain projects.
- The candidate is also expected to undertake some operational tasks related to software development on GOTO and, occasionally, on other Warwick telescope facilities on La Palma.
Particular attention will be given to applicants with experience in the field of time domain astrophysics and accreting binaries.
