Prospects and latest optical intensity interferometry results with the {MAGIC} and {CTAO}-North {LST} telescopes

Along with their gamma-ray observations at very high energies ({VHE};20 {GeV} – 100 {TeV}), the two 17-m {MAGIC} telescopes (at Roque de los Muchachos Observatory, La Palma) have also been utilized as an optical stellar intensity interferometer ({SII}) for the last six years. The calibration and validation of the setup, alongside the first measurement of the stellar angular diameter of 13 massive stars, were published in a performance paper in early 2024. Around the same time, the technical advancements developed for {MAGIC} were applied to the first Large-Sized Telescope of the northern hemisphere array of the Cherenkov Telescope Array Observatory ({CTAO}-North {LST}-1), a 23-m diameter telescope located near {MAGIC}. Three more {LSTs} should be completed beginning of 2026 and they may be equipped in the same manner as {LST}-1. We will focus on our first measurements with the {MAGIC}+{LST}-1 {SII} and our prospects for this and the {MAGIC}+{LST}1-4 {SII} for the study of several objects that are also known to emit in gamma rays: novae, such as the upcoming T {CrB}; winds from massive stars, particularly colliding-wind binaries; and Be stars which are typical companions in {VHE} gamma-ray binaries.
