And @tetsuroasano.bsky.social also from our group at the same conference in Lipari about Galactic bars, bulges and discs. @iccubdivulga.bsky.social @ub.edu @ieec.cat

This workshop aims to accelerate progress in unraveling the nature of the Gaia phase spiral and its implications for galactic dynamics by fostering the in-depth exploration and collaboration essential to tackling this grand challenge. bit.ly/4m7KDDK @msemczuk.bsky.social

"A new tidal scenario for double bar formation", Semczuk et al. This is Fig. 2: @oxfordacademic.bsky.social @royalastrosoc.bsky.social

Face-on surface density distribution, for five snapshots of both our double-barred galaxies, showing their evolution from single barred to double barred. The three right panels show different relative orientations between the inner and outer bars. When they align, like in the rightmost panel for DB2, the galaxy may appear as single barred.

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...

A new tidal scenario for double bar formation

ABSTRACT. Double bars make up a significant fraction of barred galaxies. We propose a new formation scenario for double bars that involves tidal interactio

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
