If the end is nigh, just wanted to let y’all know that I’ll keep doing what I do- comb the radio sky for signals from black holes near and far. It was a privilege to share this adventure with so many of you. 💫 Keep in touch, and the story continues here!

Astronomer here! With all the black hole news lately, it's worth a reminder that black holes are NOT like giant vacuum cleaners that "suck everything in" or similar. This is a common misconception and not at all how black holes work! 🧵

So, what DO we know about getting too close to a black hole? Well, turns out they're messy eaters, and MOST of the material gets flung out when you get too close! Here's a simulation of a star getting too close to a BH and getting shredded- a "tidal disruption event" (TDE)

First of all, worth covering what a black hole *is*. It is a region where the gravity is so strong that nothing- light, particles, etc- can escape. The area beyond which things can't escape is called the "event horizon" marked in this @ehtelescope pic of the black hole M87*.

For example, tidal forces are so strong around a black hole it's different at your head vs feet, and would pull you apart in a long thick strand. This process is called, no joke, "spaghettification." 🍝 /11

Could things fall into our new black hole sun? (heh) Sure, if it were on the right orbit! We see this w comets regularly w the sun btw- many come in on the wrong trajectory and get swallowed now as it's a star (see gif). But that is just how orbits work, no black hole magic

@ehtelescope Now, the black hole isn't "sucking in" anything, any more than our sun is actively sucking in planets that orbit it. Put it this way, if our sun suddenly became a black hole THIS SECOND, it would shrink to the size of just ~3 km (~2 mi)... /4

When a TDE happens we believe ~half the star's material falls towards the black hole to form an accretion disk just outside the event horizon, and half the material is flung out in an outflow. Worst vacuum cleaners ever! /8 (I think?)

When people study black holes via taking a pic with @ehtelescope , studying them shred stars like I do in my research, etc, it's worth noting we are taking measurements OUTSIDE the event horizon. Think the stuff that gets really close, but not falling beyond. /3

Now, this ISN'T to say black holes aren't REALLY WEIRD and dramatically affect their surroundings... but it's mainly bc of what they throw OUT, not bc they're cosmic vaccuum cleaners! And wild stuff WOULD happen if you went on a wrong trajectory and fell into one... /10

There is a non-zero chance our universe is a false vacuum, where the laws of physics are different than that of the multiverse (think env inside a bubble in a boiling pot of water). If true this means our universe could instantly end w no warning, w nothing we can do about it.

NEW PAPER: I have discovered that up to half of all black holes that shred a star "burp" material years after the initial event and turn on in radio!!! No one was expecting this, and we don't really understand why this might be! 📡💫🤩🧵

Ubiquitous Late Radio Emission from Tidal Disruption Events

We present radio observations of 23 optically-discovered tidal disruption events (TDEs) on timescales of about 500-3200 days post-discovery. We detect 9 new TDEs that did not have detectable radio...

Anyone who gets into grad school this year is a superhero. In our dept we had a 25% increase in apps for half as many spots, so 400 applicants were battling for 10 slots. Seriously, this year is a bloodbath. If you don't get an offer, it's TBH prob not you. #AcademicChatter

I am delighted to announce the arrival of “Little Dipper,” who came via C section on Oct 25, at 11:37pm. This was a surprise because I was scheduled for a C section morning of the 26th because she was breech, so we were out having a final meal at a nice restaurant downtown…

Anyone else think about how alien astronomers are probably looking at the same things we are? Like, I’m studying an explosion ~600 million light years away, and if life is a repeatable chemical process, there’s gotta be someone ELSE doing the same in the millions of galaxies…

@astro_jaz Astronomer here! If you go within 1000km of a magnetar, you would die, because the *magnetic field itself* would kill you by stripping the electrons in your body from the atoms in it. 🤯

Found my old shoulder bag from my days as a physics undergrad @PhysicsCWRU ! I embroidered equations next to the relevant objects- gravitation for planet, Maxwell’s equations by the sun, expansion of the universe by a balloon. 🤓

My proposal to use the Very Large Array (VLA) this fall in New Mexico was approved!!! We have 33 hours of radio observations of black holes that shredded stars! 📡💫🤩
