Having now been on #Mastodon for 1 month, a few observations:

- Mastodon makes me realize how much the #Twitter algorithm maximized user outrage to boost engagement for profit. Gross. Here, my feed is interesting & supportive.

- There's a culture of kindness - at least so far. It's extremely appealing & should be normalized on & offline.

- Beyond reactions to toots, people share songs, poetry & ask great questions. I can't remember the last time I found social media to be fun.

Autumn in #seattle. I don’t recall fall leaves sticking around this long in years past.

Alright, I did some HDR stuff and I think I managed to pull some nice details out of our good friend M31. I also have a decent amount of dual narrowband data, so I'd love to be able to pop those little red star-forming regions...but how? I've tried a bunch of PixelMath things and haven't managed to get it without making the whole image overly red. TIA for your suggestions!

Hello, Las Vegas! I’m here for #reinvent2022. If you’re in town and in the #cloud, I’d love to learn from your experience and share a bit of mine!

Still time to register for "Physics in Advent", an advent calendar with 24 simple experiments and physics mysteries to spark interest in #physics ... and you can win prizes, too! https://www.physics-in-advent.org #PhysicsInAdvent #PhysikImAdvent

9/ We even have a supermassive black hole at the center of our Milky Way galaxy! It's name is Sgr A* ("Sagittarius A-star") and it's about 4 million solar masses, which makes it medium-sized in supermassive black hole terms.

The Event Horizon Telescope took a picture of it in radio light last year, and it is such a gorgeous lumpy orange donut 🤩 #OurBlackHole #blackHoles #BlackHoleFriday #astronomy #astrophysics #space

New paper on the arXiv! My PhD student Vincent Schmeits and I studied a discrete-time quantum walk on an embedded graph. A lot of firsts: it’s Vincent’s first paper and it’s my first paper with my QuSoft affiliation. Vincent also wrote code to make amazing diagrams, so we can visualise the walk, like on this toroidal grid. Here’s the arXiv link: https://arxiv.org/abs/2211.12841

It's #BlackHoleFriday!!! Here's a thread about black holes from me, your friendly internet astronomer 😊

Okay, I've been trying to collect #tech people to #follow for #FollowFriday. Sorry it is not really exhaustive - probably I left out a lot of good accounts I'm following.
