At NAM 2025 in Durham @nam25-durham.bsky.social , Marcin Semczuk is speaking on "Bars in TNG50 - slowdown and formation of double bars". Marcin has published in #MNRAS Letters: academic.oup.com/mnrasl/artic...

Dear All! The registration is now open for our workshop on the Gaia Phase Spiral in the Lorentz Center (4-8 August) 🌀🔭 www.lorentzcenter.nl/winding-unwi...

How do the double bars form? It appears that tidal interactions may sometimes play a role. Read more in our now-accepted MNRAS Letter 🔭https://doi.org/10.1093/mnrasl/slad175
