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...

🚨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and credit card bills because their salaries were paused this week, even though the federal funding freeze memo was rescinded.

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.
It’s official: all funding requests made on Tuesday by postdocs for their salaries have been unilaterally rejected by NSF.
