The Cerenkov Telescope Array Observatory (CTAO) is an international collaboration building two telescope arrays to detect very high energy gamma-rays. The first CTAO School was held in June for students and postdocs to learn about the science and techniques of this field, with the first week held in Italy and the second week on the Spanish island of La Palma (which will be the site of one of the CTAO arrays). WSU student, and member of CTAO-Australia, Sanja Lazarevic attended the CTAO School, and is pictured above in front of the LST-1 telescope. LST-1, which has a 23-meter diameter parabolic reflective surface, stands 45 metres tall and weighs around 100 tonnes. However, the telescope has the ability to slew to a new poistion on the sky within 20 seconds in response to an alert from X_ray or gamma-ray satellites, to try and capture associated high-energy gamma-ray signals. As CTAO targets will include pulsars, supernova remnants and active galactic nuclei, there are many synergies with radio observations of these objects.
