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.

Prof Eduardo Martín gave a talk to "Amigos del IAC"

Yesterday, Professor Eduardo Martín, the Principal Investigator of the SUBSTELLAR project, gave an informative talk as part of the 'Amigos del IAC' programme.

This programme brings together individuals who support the Instituto de Astrofísica de Canarias in its ongoing efforts to advance our understanding of the universe, promote the high calibre of the Canary Islands Observatories, and foster a culture of science within our society.

The programme organises scientific culture and dissemination activities so that its members can increase their knowledge of the Instituto de Astrofísica de Canarias and its work.

These activities cover all the fundamental areas in which the institute is involved, primarily the dissemination of astrophysical information and the promotion of the Canary Islands Observatories.

Professor Martín, a renowned researcher in the field of substellar science, gave a talk entitled ¿Qué hay entre las estrellas y los planetas? (in Spanish), which translates as 'What lies between stars and planets?'

He talked about this fascinating area of astrophysics and provided an insight into the work being conducted by his team and himself within the framework of the project Substellar Science with the Euclid Space Mission (SUBSTELLAR), for which he received an Advanced Grant from the European Research Council.

The talk will be available here soon.

Subtellarers attended BD30

SUBSTELLAR predoctoral students Sara Muñoz, Jun-Yan Zhang (Jerry), Styliani Tsilia and Nafise Sedighi attended the conference "BROWN DWARFS KEEP THEIR COOL: 30 YEARS OF SUBSTELLAR SCIENCE" (BD30). The conference took place at the hotel Jardin Tecina , located on the island of  La Gomera in the  Canary Islands  (Spain).

The BD30 conference celebrated the 30th anniversary of the discovery of the first Brown Dwarfs and reviewed the most recent substellar studies with special emphasis on metal-poor objects.

The conference also included a tribute to our colleague and friend Prof Yakiv Pavlenko, who passed away at the end of 2024.

Representatives from the SUBSTELLAR project formed part of the Scientific and Local Organising Committees.

The SUBSTELLAR project PI, posdocs and predoctoral students presented the current status of their research works at the Conference.

Attendees to the Vatican Observatory Summer School 2025 had met by the Pope Leo XIV!

Yesterday, Monday 16 June, was an unforgettable day for the attendees, speakers and organisers of the Vatican Observatory Summer School (VOSS 2025). They had the opportunity to meet Pope Leo XIV at the Consistory Hall in Vatican City.

During the ceremony, the Holy Father addressed them.

In his speech, the Pope said he was pleased to have the opportunity to greet the participants, who are students and scholars from various parts of the world taking part in the School. He offered them his prayerful good wishes, hoping that their experience of living and studying together would be academically and personally enriching and would help them to develop friendships and forms of collaboration that would contribute to the progress of science in the service of our one human family.

SUBSTELLAR PhD students Stella Tsilia and Jun-Yan Zhang attended the meeting. During the handshake, Stella gave the Holy Father an IAC sticker.

An image of the Pontiff talking to students from SUBSTELLAR who are attending VOSS 2025 was released on the front page of Vatican News , the Vatican's official channel.
