LST and AtLAST presentations at the SPIE 2020 digital forum
The SPIE Astronomical Telescopes and Instrumentation 2020 was originally scheduled to be held at Yokohama Japan on June 2020, but it had been changed to be held on December 2020 at San Diego due to the COVID-19 pandemic. And finally, a digital forum, a fuly virtual format conference, was held on December 13-18. We presented a couple of talks and poster presentations on the progress and updates of the LST activities, which includes the first successful demonstration of a 2-element wavefront sensor with the Nobeyama 45-m telescope (Tamura Y., et al.) and a conceptual study of large-format imaging spectrograph for uncovering first star-forming galaxies during the epoch of reionization and beyond (Kohno, K., et al.). An overview of AtLAST project was given by Klaassen, P., et al., and we found many intriguing talks which are related to LST and AtLAST development activities. The LST and AtLAST SPIE papers will become available via the SPIE sites and arXiv.
