    [Interview] Observing Black Holes With Just One Telescope
    Jul 15 2024
    Previously the only way to image black holes was with the Event Horizon Telescope, a combination of many radio telescopes across the globe. It is complicated and time-consuming. But with Vera Rubin going online soon, there might be a simpler way to observe black holes with a single telescope using a really clever method. 🟣 Guest: Dr Matt O'Dowd https://www.mattodowd.space/ 📜 Resolving the Vicinity of Supermassive Black Holes with Gravitational Microlensing https://arxiv.org/pdf/2210.10500 👉 PBS Spacetime https://www.youtube.com/@pbsspacetime 🦄 Support us on Patreon: https://patreon.com/universetoday 📚 Suggest books in the book club: https://www.goodreads.com/group/show/1198440-universe-today-book-club 00:00 Intro 01:45 Observing gravitationally lensed quasars 12:58 Why Vera Rubin 19:04 Best case scenario 23:22 What do we know about black holes 38:21 Current obsessions 44:31 Final thoughts 📺 VIDEO VERSION https://youtu.be/m2xtVfpfeWQ 📰 EMAIL NEWSLETTER Read by 60,000 people every Friday.
