Since its origin in December 2017, the TEIDESAT project was founded and is formed and led by a team of students, initially from the University of La Laguna and, later, also from the University of Las Palmas de Gran Canaria and other universities, whose objective is to develop its own space mission. In particular, the goal is to design, manufacture

The discrepancy between chemical abundances calculated from optical recombination lines (RLs) and collisional excitation lines (CELs) is an important unsolved problem in nebular astrophysics. In planetary nebulae (PNe) there is increasing evidence that the discrepancy is due to the presence of two gas phases: a hot component with standard

In the last two decades, Spain has built up a strong infrared community which have successfully contributed, at Co-I level, to the construction and to the scientific exploitation of basically all European InfraRed (IR) space instruments. The IAC has contributed to the construction of infrared instruments for the space telescopes ISO (ISOPHOT-S) and

This research project endeavors to deepen the understanding of the AGN phenomenon and its impact on how galaxies evolve, both from an observational and a theoretical perspective. Four groups of researchers, with proven experience and extensive knowledge and skills in different areas of Extragalactic Astrophysics directly or indirectly related to

The collaboration Estallidos has been working together for more than two decades. In the present edition, we have organised the research work into five Objectives which are described in the common MEMORIA presented by the coordination node (CIEMAT). The tasks proposed by the various nodes are closely intertwined. They are organised according to our

Although thousands of brown dwarfs and extrasolar planets have been discovered up to date, their formation and evolution models remains unknown. Hence, it is necessary to identify these objects in a wider range of effective temperature, gravity and metallicity to understand them. The main scientific objective of our project is to identify and
