Now the @insidehighered.com map is updated to show >800 visas revoked across 150+ colleges in 41 states. Ohio State's known number of revocations increased from 7 to 11.
Orange map of the USA with black dots at locations where international student visas have been revoked. Text reads, "As of April 11, over 150 colleges and universities have identified 800-plus international students and recent graduates who have had their legal status changed by the State Department. Source: Inside Higher Education Analysis, Ashley Mowreader. Some institutions have shared publicly that students lost visas but have yet to disclose the number of students impacted. These are documented on the map, but the number is unknown."

It’s paper day! Check out our latest paper on galactic shapes in FIREbox. Tip of the hat to Courtney Klein for leading this effort! 🔥 📦 🌌 arxiv.org/abs/2503.05612

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

“If the freeze is not stopped, I might lose my house." Some NSF-funded postdocs are having trouble paying rent and credit card bills because their salaries were paused this week, even though the federal funding freeze memo was rescinded. www.statnews.com/2025/01/30/t...

Apparently all the PhD researchers holding prestigious NSF-funded research fellowships are having their salaries withheld until some unspecified time when the leadership figures out how to eliminate any grant funding that doesn’t align with the president’s political ideology.

The @aasoffice.bsky.social will issue full registration refunds for all of our colleagues impacted by the devastating fires in CA. If you are an #AAS245 registrant and in CA standby for an email on how to request your registration. We at the AAS are heartbroken for you and ready to support.

Effects of galactic environment on size and dark matter content in low-mass galaxies
We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,200 galaxies (886 ce...

In the blink of an eye, Francisco more than doubled the size of our research group. As a postdoc, he has really exceeded all expectations! 🌌 🔥

The @aasoffice.bsky.social CSMA hosted a great session at SACNAS on building community in astronomy w/ @astrojennifer.bsky.social, @astroarianna.bsky.social, @skyientist.bsky.social, & Sebastian Monzon. Among the great lessons from the panel, @astroarianna.bsky.social shared this amazing wisdom. 🔭
Screenshot of a slide from Prof. Arianna Long's presentation at the SACNAS conference. The header says "lessons learned", and the bullet points read "Community takes work!!!!! Invest in one another, connection is key to sustainability. It can't always be about the bad. Joy must also be centered to sustain the work / connections. Community can be formal and informal. The goals can (and should) be flexible. Community can be built within a system, but communities outside the system (and decentralized) can often do more."
