There’s a great wave rippling through our galaxy The dynamics of our galaxy become evermore complicated as today's authors discover a mysterious wave propagating out towards its outskirts.

I'm hiring 1-2 postdocs this year! If you're interested in:

GW astrophysics
(Binary) Stellar Evolution
Stellar dynamics (esp. w/ massive BHs)
Galactic dynamics (inc. stellar streams)

plz consider applying! You don't need letters initially, just a list of references.

Excited that my new paper with J. Nibauer is out this week : arxiv.org/pdf/2508.02666

We use stellar streams to map the full radial density profile of dark matter halos. With deep imaging from Euclid, Roman, ARRAKIHS, and Rubin, streams will be powerful probes of dark matter physics.

🔭 These new #Gaia maps are the best reconstructed views of how our #MilkyWay galaxy might look to an outside observer. They show us our place in the Universe like no other mission has before👇

A model image of what our home galaxy, the Milky Way, might look like face-on: as viewed from above the disc of the galaxy, with its spiral arms and bulge in full view. In the centre of the galaxy, the bulge shines as a hazy oval, emitting a faint golden gleam. Starting at the central bulge, several glistening spiral arms coil outwards, creating a perfectly circle-shaped spiral. They give the impression of someone having sprinkled pastel purple glitter on the pitch-black background, in the shape of sparkling, curled-up snakes.

A model image of what our home galaxy, the Milky Way, might look like edge-on, against a pitch-black backdrop. The Milky Way’s disc appears in the centre of the image, as a thin, dark-brown line spanning from left to right, with the hint of a wave in it. The line appears to be etched into a thin glowing layer of silver sand, that makes it look as if it was drawn with a coloured pencil on coarse paper. The bulge of the galaxy sits like a glowing, see-through pearl in the shape of a sphere in the centre of this brown line

The ESA #Gaia mission has delivered the best Milky Way maps to date and taken its last starlight before spacecraft retirement 🔭

Thanks so much to the +500 guests who showed up for my live outreach show at the Bremen Theatre in Copenhagen last night! I couldn’t have asked for a better evening and I’m still buzzing from this experience ✨⭐️

Excited to share PhD student, Sioree Ansar's, paper investigating the properties of galactic bars in the FIRE-2 simulations. Ansar finds that 8/13 FIRE-2 galaxies form bars. She is on the postdoc job market this year, so look out for her application!
