"A closer look at the spur, blob, wiggle & gaps in GD-1" arxiv.org/abs/1911.05745 "We constrain the stream track and density [...] and find 3 large under densities and significant residuals in the stream track lining up with these gaps" #GaiaMission #GaiaDR2

"Clusters & mirages: cataloguing stellar aggregates in the #MilkyWay" arxiv.org/abs/1911.07075 by #GaiaMission cluster dream team Tristan Cantat-Gaudin & @frediferente "The only confirmed cluster located further than 500 pc away from the Galactic plane within the Solar circle is NGC 6791"

One of the gifts of the #GaiaMission is that it gives us the #MilkyWay in #3D.

A team of computer scientists are using Gaia-derived data and a supercharged travelling salesman algorithm called Concorde to compute minimal star routes. (See: math.uwaterloo.ca/tsp/star/index…). They've included my data set of luminous stars (abs. mag. < -2) here: math.uwaterloo.ca/tsp/star/kj378…

This was the definitive map of our galaxy in the astronomy books I read when I was young. academic.oup.com/mnras/article/…

🪐🌝⭐️Calling all Australian astrophysics students⭐️🌝🪐 Our annual Mt Stromlo Student Seminars is going completely online! So please join us in late-November by registering for a talk, today! Come and share your science with your fellow astronomy peers!!!

Using methods from biology, we use the chemical DNA of 78 stars in the Solar Neighbourhood to construct an evolutionary tree. The tree structure reflects the ages and dynamical properties of the stars, showing its potential for interpreting high-dimensional chemical DNA. Paula Jofre

In case you need a little perspective today --> ESA Gaia released the most precise 3D map of the Milky Way ever made. Looks like @GaiaSky_Dev let's you check out this #gaiaEDR3 data in #VR too. Crazy cool. Via Neel V. Patel MIT Technology Review technologyreview.com/2020/12/03/101…

In case you missed it yesterday, you can now download the entire catalogue of 588570 stars’ worth of high-resolution optical stellar spectra that formed GALAH DR3. 🧵👇

Join us for a (virtual) day of all things Milky Way modelling at EAS Annual Meeting 2021 on the 2nd July, lead by Francesca Fragkoudi and @frediferente - should be a good one!

Early Career Astronomers session EAS Annual Meeting We now looking for speakers and particularly love to hear from astronomers from traditionally marginalized backgrounds and underrepresented groups. Contact as at [email protected] or through the EAS abstract portal until 2nd March

I think this is the most extraordinary image of the Milky Way I have seen petapixel.com/2021/03/16/pho…

Anthony Brown (Leiden) kicked off the #edr3workshop with a great presentation on not only Gaia EDR3, but DR3 and DR4! Check it out: drive.google.com/file/d/1dyGdGH…
