IAA - CSIC Severo Ochoa Center


The Institute of Astrophysics of Andalusia (IAA-CSIC) has obtained the Severo Ochoa Center of Excellence distinction, an accreditation that recognizes the centers that carry out basic border research and are among the best in the world in their area of ​​work. They stand out for their high competitiveness, their ambitious strategic plans, high quality production and great capacity to attract talent. Endowed with a budget of one million euros annually for four years, the badge forms part of the Subprogram of Institutional Strengthening of the State Plan for Scientific and Technical Research and Innovation.

The Severo Ochoa centers have been selected for their trajectory in the five years of reference quoted in the call and their strategic programs, after a rigorous evaluation by an international committee made up of top-level researchers and renowned prestige in their respective fields. This guarantees the quality, the level of excellence and the impact of the research carried out by the selected centers.

The Institute of Astrophysics of Andalusia (IAA-CSIC) is the only Andalusian center with the Severo Ochoa distinction.

Severo Ochoa Centers


SO-IAA project

The IAA holds a solid and unique position in astrophysics and space research in Spain, being the largest astrophysics research center in the CSIC. Its multidisciplinarity and experience in multi-range astronomy favor the existence of transversal synergic projects.

Our stated objective is to transform the IAA into one of the leading institutes of astrophysics and space science in Europe and to develop its research and structure at a level such that the IAA is placed in a privileged position for the exploitation of the next generation of advanced experiments and innovators. For this, we will take advantage of the opportunities offered by our Calar Alto Observatory (CAHA) management to occupy unique niches in observational astronomy and continue to use it as a technological test bed. We will strengthen our position in participation in international space missions, such as JUICE or Solar Orbiter. We will focus on participation in the SKA, an international effort to build the largest and most sensitive radio telescope in the world, which will play a transformative role in astrophysics. We will also participate in the instrumentation for the European Extremely Large Telescope (ELT), the largest optical telescope to date (class 40m). On the way to these long-term objectives, we will carry out preparatory work for the SKA through the scientific exploitation of its precursors currently in operation and under construction (MeeRKAT, ASKAP, JVLA, LOFAR) and we will operate the telescopic facilities of the European Southern Observatory (ESO) .

The technological development achieved in recent years has allowed to reach an angular resolution in the observations of the order of tens of milliseconds of arc (even better with very long base interferometry), which correspond approximately to the Earth-Sun distance in the regions of formation of the closest massive stars and they are sufficient to separate individual stars in galaxies of the local group. Likewise, it has been possible to reach spectral resolution limits of the order of 1 m / s, which allows us to detect planets similar to the Earth around nearby stars. CARMENES is particularly competitive in this context, since it has been specially designed for the detection of planets similar to the Earth in contrast to other existing instruments. Combined with our better understanding of complex chemistry and the corresponding spectroscopic signatures of planetary atmospheres, this means that we are now in a position to connect the minute to the big and explore the interrelationship between planets, stars and galaxies, not only at multiple wavelengths. wave, but also on multiple scales that span many spatial scales. With this perspective in mind, our scientific strategy will be based on three scientific pillars that focus on and intertwine increasing spatial scales:

  1. Towards the understanding of planetary systems
  2. Star formation in the Milky Way and the Local Universe
  3. Galactic Evolution and Cosmology
