Contact: Marie Van de Sande |
| We invite applications for a PhD position in computational astrochemistry at the School of Physics at University College Dublin, Ireland. You will work with Dr Marie Van de Sande on the ERC Starting Grant ASHES on dust formation in the outflows of asymptotic giant branch (AGB) stars. | | ▸ more | Most stars will go through an AGB phase near the end of their lives, losing their outer layers by means of a stellar outflow and enriching the interstellar medium (ISM) with the building blocks for the next generation of stars and planets. This outflow is driven by dust formation. Despite the importance of dust, we still do not know exactly how it is formed.
You will extend a large chemical reaction network to include dust nucleation, using the results of quantum chemical calculations, and calculate the first 1D bottom-up dust growth models. As a next step, you will create 3D chemical models by post-processing hydrodynamical models, helping to close the gap between theory and observations. As part of the ERC Starting Grant ASHES, there are ample opportunities for attending conferences, workshops, and research stays.
This project would be suitable for a student with a degree in chemistry, physics or astronomy who wants to build on their skills in coding (python and Fortran), data analysis and visualisation, and would like to work in chemical kinetics modelling.

-Perform general ARC duties, including answering Helpdesk tickets, contributing to testing of tools and playing a proactive role in the improvement of user documentation.
-Undertake Astronomer-on-Duty shifts in Chile.
-Constructively work together with other ARC staff and ALMA operations staff around the globe.
-Conduct astronomical research for up to 20% of the time.
-The tasks are not limited to the above and a flexible approach and willingness and capability to adapt is required.
Reports to:
The post holder reports to the Head of the ALMA Regional Centre (ARC) Department. The ARC is a department of currently 13 highly skilled and motivated staff and is part of the ESO ALMA Support Centre (EASC) division.
Key Competences and Experience:
Essential Competences and Experience
-Practical experience with astronomical observations, not necessarily radio interferometry.
-Excellent cross-disciplinary communication skills, both oral and written.
-Demonstrated ability to work effectively in a team, have an eagerness to contribute to team performance, and a positive approach toward building links across teams in an international multi-cultural environment.
-Good critical thinking and problem-solving skills, demonstrated by a pro-active approach to contribute ideas for improvement and future developments.
-Flexibility in adapting to changes of requirements and priorities as well as of assignments.
-Good time management and prioritisation skills.
-Open and friendly attitude to interact with a variety of users.
Desirable Competences and Experience
-Working knowledge of radio interferometric astronomical observations, including common calibration steps.
Qualifications:
Essential educational level: PhD in Astronomy, Physics or equivalent.
Language skills:
Excellent working knowledge of English.

| 2 to 3-Year Postdoctoral Appointment on extragalactic mm-wavelength surveys, CAB CSIC-INTA Spain | Closing date: 2026-04-01
Contact: Itziar Aretxaga |
Center for Astrobiology (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 | | ▸ more | 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)
