You are defending the open killing of everyday Americans for exercising their Constitutional rights.
First, the mother of a 6 year old child. Now, an ICU nurse to veterans. Both shot at nearly point blank range.
All without reflection or remorse. People will not forget this.
When I was in Minneapolis, I heard a number of crazy stories. But near the top of the list:
A couple of off duty ICE and CBP officers were going to dinner in Minneapolis. They were doxed and their location revealed, and the restaurant was then mobbed. The officers were locked in the restaurant, and local police refused to respond to their pleas for help (as they've been directed by local authorities). Eventually, their fellow federal agents came to their aid.
This is just a taste of what's happening in Minneapolis because state and local officials refuse to cooperate with immigration enforcement. They have created the chaos so they can have moments like yesterday, where someone tragically dies and politicians get to grandstand about the evils of enforcing the border.
The solution is staring everyone in the face. I hope authorities in Minneapolis stop this madness.

“No government—regardless of which party is in power—should dictate what private universities can teach, whom they can admit and hire, and which areas of study and inquiry they can pursue.” - President Alan Garber hrvd.me/GarberRespond347t

This is the most corrupt bargain we've ever seen in American history: Elon Musk gave millions to fund Trump's campaign, and now Trump has given him the keys to our government.
We are fighting this in Congress, in the courts, and in the streets. We will not back down.
Thank you @ErikWernquist for creating this absolutely jaw-dropping cover! ✨🌌😻
I had the pleasure of creating an illustration for @MartijnOei and his team's article on their discovery of black hole jets on the scale of the cosmic web.
Really proud to see this illustration today serving as the cover of the September 19 issue of @Nature magazine!

A massive discovery 🔭
Astronomers have spotted the largest plasma jets ever seen, streaming from a supermassive black hole 7.5 billion light-years away in a galaxy named Porphyrion.
These jets span 23 million light-years!

Longest, strongest black hole jets of all-time discovered
How large can a black hole jet get?
With the new discovery of Porphyrion, the answer is at least 24 million light-years, and that was when the Universe was just half it's present size!

NEWS: Astronomers have discovered a black hole that’s blasting out the largest and longest jets of hot plasma ever observed. Nicknamed Porphyrion after the mythological Greek giant, this colossal jet system spans 23 million light-years, equivalent to lining up 140 Milky Way galaxies back-to-back! Congrats to lead author @MartijnOei of @Caltech & the entire team! Details 👉 keckobservatory.org/porphyri…

BOOM 💥 Our @Nature paper is out and is featured on the front cover of the issue.
The paper, led by @MartijnOei, is about a giant radio outflow (7 Mpc) from an active galaxy at z~0.9. This has potential implications on the magnetization of the LSS...

Excited to share our preprint, with Jo Warren, @jcrwhittington, and @behrenstimb! Hippocampus famously supports memory and scene construction, but recent state-space models have also explained a wealth of hippocampal results. Maybe it does both?

Two papers on Giant Radio Galaxies, by @MartijnOei
In the first one, a catalog of 2050 (!) GRGs from @LOFAR LoTSS-DR2 is reported arxiv.org/abs/2210.10234
In the second, a GRG is used to estimate the temperature of the IGM arxiv.org/abs/2210.10156

First came 3C236 (1974), then came J1420-0545 (2008) after 34 years and now after 14 years came Alcyoneus- the largest giant radio galaxy of ~5 Mpc! @LOFAR made it happen, continuing the Dutch telescope tradition of finding the largest of the giants.

But why "Alcyoneus"? The answer is in footonote #2!
