Presentation

Substellar Science with the Euclid Space Mission (SUBSTELLAR) is a project aimed at mining the Euclid surveys for pushing the frontier of knowledge in substellar science.

SUBSTELLAR is an Advanced Grant awarded to Prof. Eduardo L. Martín (Instituto de Astrofísica de Canarias) by the European Research Council. 

The primary science goal of SUBSTELLAR is to reveal and investigate the faint objects that lurk in the darkness beyond the limits of stellar engines, using mainly the new data arriving from the ESA Euclid space mission.

Euclid is a space mission led by the European Space Agency (ESA) to conduct a deep, single-epoch survey of 15,000 deg2 of sky with visible and near-infrared photometry and spectroscopy, and 40 deg2 multi-epoch very deep surveys. Euclid was launched at July 1st 2023.

The unprecedented combination of sensitivity, areal coverage, spatial resolution, data homogeneity and spectral information will naturally be of tremendous benefit to other areas of astrophysics. Two Euclid Independent Legacy Science (ILS) programs have been designated by ESA to develop and pursue independent science programs that capitalize on the unique data products of the Euclid surveys. SUBSTELLAR will re-use existing ground-based and space-based multiwavelength data to complement the new data obtained with the Euclid space mission.

Riccardo Mordente, Erasmus+ Traineeship at Instituto de Astrofisica de Canarias (SUBSTELLAR)

Riccardo Mordente, a graduate student from La Sapienza (Rome, Italy) spent two months with SUBSTELLAR group (April and May 2026). His stay at the IAC was subsidized by Erasmus+ mobility program. 

During the stay, Riccardo worked on PCA analysis of the EUCLID Q1 spectra of the ultracool dwarf candidates. 

He presented the work he did in a talk given to the SUBSTELLAR group members. His training at the IAC was supervised by Dr Nikola Vitas. RMordente at IAC

Sara Muñoz Torres, SUBSTELLAR project pre-doctoral researcher held a special outreach event with pupils from IES in Seville

On February 25th, as part of the international initiatives celebrating the International Day of Women and Girls in Science, a special outreach event took place at IES Joaquín Romero Murube, located in one of Seville’s working-class neighbourhoods, organised by Sara Muñoz Torres, SUBSTELLAR PhD student.

The activity aimed to bridge the gap between cutting-edge research and the classroom. Instead of a standard lecture, the event centred on an informal, highly interactive conversation with the students. The engaging Q&A format allowed the young audience to take the lead by asking insightful questions about the mysteries of the cosmos, the study of brown dwarfs, and the latest advancements from missions such as the Euclid space telescope.

Beyond the science, the students were deeply interested in the human side of research. The discussion covered the realities of a professional career in Astrophysics, detailing the day-to-day work at the Instituto de Astrofísica de Canarias (IAC), and the personal journey required to become a researcher.

The initiative was a remarkable success. It sparked a genuine curiosity among the students, demonstrating that a career in STEM is accessible and exciting for anyone.

SUBSTELLAR Project Announced it's First Scientific Conference "SUBSTELLAR ASTROPHYSICS"

Substellar Scientific Conference 2025

 

SUBSTELLAR Astrophysics Conference, Tordesillas, Spain, 10 - 14 August 2026

This conference will bring together researchers interested in Substellar science with special emphasis on exploiting the wealth of data provided by Euclid and complementing it with other surveys and follow-up observations.

The conference is supported by the European Research Council Advanced grant nicknamed SUBSTELLAR.

A total eclipse of the Sun will take place during the conference (August 12, 2026).
