An image from part of the GOODS-South portion of the FUEL Survey showing random pointings of scattered around the area and a mosaic of pointings covering the UltraDerp Field.

Introducing the Far-Ultraviolet Extragalactic Legacy (FUEL) survey! We uniformly reduced and aligned all Hubble far-UV imaging in the extragalactic legacy fields. Shout out to my student Aliakbar Kavei for the great work completing this project. Check it out! 🔭

Great article from @rboyle31.bsky.social on mysterious Little Red Dots and how they might represent a class of objects we've never really seen before: a stellar atmosphere powered by black hole accretion.

stay tuned for a spicy alternative take that should appear on the arXiv later this week! 🧪🔭

Should I Stay or Should I Go? Clumps and Inward Migration Something is missing in the middle. In JWST JADES galaxies, young clumps drop out in the inner regions, while clump structure shifts from the outskirts to the center.

Feed the Fire, Fade the Metals Are cosmic clumps “homegrown”, or fueled by fresh inflow? Today’s authors find that star-forming clumps are usually more metal-poor than the disks around them.

A bit inconvenient for potential alien life forms if they’re constantly being incinerated by their own suns

Really enjoyed reading your book @ryanjfrench.bsky.social and it was a pleasure to write about it. Thanks for writing such a clear and engaging read☄️🔭

Writing a scientific paper as a first author for the first time is so so daunting, intimidating, terrifying 🥺

But it doesn't have to be this way.

What are some tools, support, encouraging frameworks that professors, mentors and advisors share with their students to write their first papers? ✍️🏼🙏🏼🔭

The Shape of Space: Hunting for the Topology of the Universe- with Yashar Akrami YouTube video by AURORA at UCR

🔭 Dr. @yasharakrami.bsky.social ((IFT) UAM- CSIC) joined us for an AURORA Astro Webinar on one of the most fascinating questions in physics: what is the shape of the Universe?
Could its topology leave subtle imprints on the cosmic microwave background?
🎥 Watch here: youtu.be/-_6ZEnp4UX8

We’re happy to invite you to our next AURORA Astro Webinar! Dr. Irene Shivaei from the Centro de Astrobiología (CAB) in Madrid will be giving a talk over Zoom. We hope you can join us! Send us a direct message to get the link, or join us in person in the Pierce Observing Room.

A skyscape is shown over a rocky landscape. In the starry sky are the central band of our Milky Way Galaxy on the left, a meteor trail on the right, the dim band of zodiacal light in the center, and the photographer holding a light just below the center. The path of the light is shown as a bright streak in the bottom part of the frame. Please see the explanation for more detailed information.

There's a #LunarEclipse tonight! If you're in the dark region here, and if you have a view of the Moon at the right time, you'll see the eclipse. Check www.timeanddate.com/eclipse/luna... for more info and timings for the eclipse in your location. (Here on the East Coast, totality peaks around 3am.)

Ah, the joys of finding the ‘perfect’ galaxy image! The article is about EXCELS-63107, but this image was chosen for general context. For low metallicity. Appreciate the keen eye!
