As a 19 year old working with James Binney, the beauty of Galactic Dynamics lured me into astrophysics. With GAIA tracing orbits of billions of stars, now is the most exciting time to be dynamicist. Join us in NYC for our summer school! galacticdynamics.nyc

Elena Massara led our effort to show that by weighting low density regions with a marked power spectrum, surveys can yield new insights into neutrinos and dark energy twitter.com/higgsinocat/st…

New paper! In work led by Dan Gole, we find that modest levels of protoplanetary disk turbulence stop solids from collapsing into planetesimals. We think turbulence is strong close to the star, so this may hinder in situ formation of close-in exoplanets.

Would be interesting to look at in the context of using Burger's equation to model growth of large-scale structure (see e.g., ui.adsabs.harvard.edu/abs/2010PhRvD.…)

Movie Night! Behind the Curve provides a peek into the world of Flat Earthers. In the film, proponents share their reasoning and discuss their experimental approaches to proving their world view. Scientists give their take on the flat Earth conspiracy. eventbrite.com/e/movie-night-…

Time to fly back home and do more science at @FlatironCCA. 2020 starts off with an amazing experience, beautiful place, and lot of fun. Seeing @ACT_Pol @CMB3K and @CLASS_telescope was priceless. I will be back for @SimonsObs! pic.twitter.com/o8z90UXTEU

Lily Zhao (Yale) explained spectroscopic hardware and calibration to the whole @FlatironCCA yesterday. She’s got the best calibration for any spectrograph ever (I think!!). pic.twitter.com/bJNfJcSDHD

The planet formation group @FlatironCCA is exploring different approaches to understand how small solid particles grow in turbulent protoplanetary disks. Dan Gole uses direct simulations, at resolutions up to 512^2 x 2048, to study planetesimal formation. pic.twitter.com/3lFUArRrZ4

Time to say farewell to one of the great observatories, the Spitzer Space Telescope. Like its namesake, Lyman Spitzer, the telescope has taught us so much about the universe. Congratulations to all who made this mission a tremendous success. jpl.nasa.gov/news/news.php?…

A cluster of newborn stars was found on the outskirts of the Milky Way by @FlatironCCA's Adrian Price-Whelan (@adrianprw) & colleagues. Presented today at #AAS235. The gif shows position of the stars relative to our galaxy & the Magellanic Clouds. For more simonsfoundation.org/2020/01/07/mil… pic.twitter.com/KUd9jETJ66

Hubble images have shaped our view of. the universe. WFIRST images will be 100x bigger! 50 million stars in Andromeda in. a single observation.
