Paper Acceptance Day! 🎉 Galaxies in denser regions of our universe are structurally different. Alan Dressler showed this in 1980. 45 years later, we're still arguing about why. With ~3 million HSC galaxies, we try to untangle it. 🧵 (1/n) #astronomy 🔭 🧪

🔭 Paper Day! 🧪 Introducing Hyrax — an astro-focused ML framework built for the era of Rubin, Roman, and Euclid Handles the entire ML lifecycle: from data acquisition → training → inference → interactive latent-space discovery. pip install hyrax (1/n) 🧵 #astronomy #astrocoding #extragalactic

Thrilled to be part of the 2026 RCSA Fellows cohort — grateful for the opportunity and looking forward to learning from this amazing community! ❤️

RCSA has selected a new class of outstanding postdoctoral scholars in the third year of the #RCSAFellows initiative, which aims to increase faculty excellence in the physical sciences through a multiyear program of job search preparation, professional development, and community building.

Lights, camera, action! The world's largest digital camera has been installed at NSF–DOE Rubin Observatory! 🤩 The LSST Camera was the final major component of the observatory. With it in place, Rubin officially enters its final phase of testing!🔭 🔗: rubinobservatory.org/news/lsst-camera-installed

🔭 Has someone already made an Astro X ML/AI starter pack?

Figured I would get in on this whole starter pack thing and list (in whatever order bsky chooses) scientists working on studying galaxies (broadly defined, including galaxy formation/evolution + near-field cosmology). If I missed you and you'd like to be added, let me know! 🧪🔭 go.bsky.app/5ZZtqDy

Are you on the Postdoc market and excited about early science with @vrubinobs.bsky.social, especially time domain, solar system, near field cosmology, or SETI? Well check out the @dirac-institute.bsky.social fellowship position that just got posted! apply.interfolio.com/158267

OMG look how glorious 🤯 #NancyGraceRoman #SpaceTelescope #astronomy

Dr. Amber Straughn (she/her)@astraughnomer.bsky.social · 2y ago

The gorgeous mirror for NASA's Nancy Grace Roman Space Telescope was recently delivered to Goddard! Huge milestone for the mission - this is the last piece of the telescope to arrive 🎉 www.nasa.gov/missions/rom... #nasa #astronomy

Perhaps more timely now than ever: We are hosting a scientific symposium (among other events -- see pic) at UChicago, focused on promoting and retaining women in astrophysics. Symposium registration (link in next tweet) is open through Jan. 30 and we offer hybrid attendance. 🔭👩‍🔬🧪

Grateful to see our recent work covered by space.com ! The article is wonderfully done @monisharavis.bsky.social ! It captures everything so well while being an interesting and easy read! :) #🔭 #astronomy

🎉 🎉 Paper + Press Release Day 🎉 🎉 Using 3 million Hyper Suprime-Cam galaxies, we demonstrate with >5σ confidence that galaxies in denser environments are up to 25% larger than their counterparts with similar mass and morphology in less dense regions of the Universe. (1/n) 🔭, #astro

Eclipse: You shall wait for years, make careful plans, drive hundreds of miles for five miraculous minutes. Aurora: U up?

What an amazing night in Seattle!
