AIRI design by Johns Hopkins University

AIRI (Araucaria InfraRed Imager) is an infrared camera, designed by experts and engineers from the Johns Hopkins University, that will be installed on the 2.5-m telescope at OCM. The design of the camera was presented at the SPIE event: Astronomical Telescopes + Instrumentation, in 2026 in Copenhagen, Denmark.

HALO, Fairall 9? How are you?

The HALO project revealed that the accretion disk of the AGN Fairall 9 is significantly more expansive and physically complex than standard theoretical models predict. This was done by tracking time delays between light captured in different passbands, the method known as photometric continuum reverberation mapping.
