So many cool new #galactic papers came out today! ☄️ Paper #1 on my list is by @catherinezucker.bsky.social et al. They use the DECaPS2 photometric survey to create a massive, 6.1 billion voxel 3D catalogue of dust in the southern galactic plane! It complements the existing Bayestar map really well.

Their dust map at various different distance ranges. Note how good the angular resolution is.

A top-down view of their 3D dust map, also compared to the Bayestar19 map (which this map complements really well.)

A schematic overview of their pipeline. It's cool how much open source software they use!

The @esa.int Gaia satellite will take its final scientific measurements on Wednesday. 🔭 This will conclude a 12 year series of continuous observations. Larger Gaia data releases are still in progress, but Gaia has already had a HUGE impact on our understanding of the #milkyway. (Image: ESA)

A SPICY new EXor outburst! arxiv.org/abs/2401.09522 One intriguing result is that, while the outburst faded, TiO absorption appeared but then disappeared, a behavior not previously seen. This unexpected finding places strong constraints on where the outburst emission originates. 🔭 🧪⚛️

If you're applying for grad school in astronomy, the University of Hertfordshire (just north of London) is accepting PhD applications (due by the end of the month). I have two projects (linked below), one on mapping the Galaxy and the other on the variability of young stars. 🔭 🧪

Yesterday was the 20th anniversary of the launch of the Spitzer Space Telescope. Its discoveries and archives continue to impact astronomy. Here are some personal highlights: Spitzer found 1000s of protostars and young stars with disks (green dots) in molecular clouds (red) such as those in Orion. 🔭
