The Astronomical Observatory of Trieste (OATs) is one of the 17 Italian institutes that form the National Institute for Astrophysics (INAF). Besides being involved in frontier research in Astrophysics, OATs also carries out intense outreach and educational activities.

Active areas of current research include many of the main international astrophysics research fields: galaxies and cosmology, stars, stellar populations and Intergalactic Medium, the Sun and the solar system, astrobiology and exoplanets, relativistic and particle physics, new technologies and instrumentation.  The number of research staff involved in the single research fields varies and there is considerable involvement in cross-disciplinary research.

The development of research programmes largely depend on funding sources external to the Institute, and therefore most active research areas may alternate  in time as a result of successful applications to EU and international research calls.

OATs shares projects, facilities, activities, and students’ tutoring with the Department of Physics of the University of Trieste. In addition, OATs has established tight collaborations with Research Institutes located in the Trieste area such as SISSA, ICTP and INFN.

The core of  outreach and educational activities is the educational observatory of the dome dedicated to Margherita Hack which is  located at Basovizza Observing Station. Several telescopes are hosted at the station, among them is the 60cm Marcon telescope designed with the purpose of didactic observations for the general public. An interactive multimedia laboratory is also located in Basovizza. In addition to activities at the Observing Station, several didactic activities are carried out at schools, and  public conferences are organized.

Information for international researchers and students: 

OATs central office helps international students with pre-arrival and arrival procedures.

OATs is also partner of the Welcome Office Friuli Venezia Giulia office that offers support to researchers arriving in Trieste.

International Partnerships: 

OATs is involved in many large International Collaborations.

Building on the expertise developed with the key-role participation in the ESA Planck mission, our Institute has now a strong involvement in the future ESA Euclid mission, holding the coordination of the Science Ground Segment, an intense participation to the activities of several Science Working Groups, also hosting the Italian Euclid Science Data Centre.

OATs researchers have been involved in the design, development and installation of the ESPRESSO spectrograph, currently in operations at ESO Paranal Observatory located in Chile.  ESPRESSO is the leading instrument in the world for exoplanets search and characterization and OATs researchers can now benefit of state-of-the-art observations in this field. OATs researcher have been moreover involved both in the upgrade of the FORS2 instrument for the ESO VLT - Very Large Telescope and in the design activities of the HIRES spectrograph for the forthcoming 39-meter ESO giant  telescope, named ELT - Extremely Large Telescope, in particular for the definition of the science cases, development of control electronics, control software and data analysis software.

Furthermore, OATs researchers have a growing interest in the Square Kilometer Array (SKA) project, with participation to the activities of pre-construction phase and definition of the key science goals.
