👏Congratulations Dr. Bernet!

His thesis focused on the evolution and dynamics of the Milky Way thanks to the data of @esa.int #Gaia mission, and it was done under the supervision of researchers Teresa Antoja and Pau Ramos!
Today, Marcel Bernet from our group is defending his viva "Data-driven diagnosis of the Milky Way disk dynamics" at the @ub.edu @icc-ub.bsky.social @ieec.cat Congratulations!!!!

I think that this is a *huge* result for galactic dynamics & stellar streams - the fact that our galaxy's disk is probably full of *thousands* of these streams is amazing! Far more are detectable than previously thought - thanks to Sebastian's algorithm, SigMA.

We studied 12 disk streams found in a 250$^3$ pc$^3$ volume in the solar neighborhood, which we define as coeval and comoving stellar structures with aspect ratios greater than 3:1. Using \emph{Gaia} ...

☄️Hayabusa2 mission just got more exciting!

💫New observations led by @ua.es #ICCUB’s Toni Santana-Ros reveal asteroid 1998 KY26 is just 11m wide and spins every 5 min!

This poses a challenge for the mission, which will attempt a brief ‘kiss’ manoeuvre in 2031 to collect data

Can spacecraft Hayabusa2 touchdown? New study reveals space mission’s target asteroid is tinier and faster than thought. | ICCUB
New observations reveal asteroid 1998 KY26 is just 11 metres wide and spins every 5 minutes, posing new challenges for Japan’s Hayabusa2 mission in 2031, when the spacecraft will attempt a delicate ‘kiss’ manoeuvre, briefly touching the asteroid’s surface to collect data without landing.
