Extragalactic astronomer (black holes, galaxies, galaxy clusters, stellar pops) who also dabbles in planetary astronomy. Really, basically a pixel pusher.

Had a visit in our den tonight from a giant hairy desert scorpion.This one was about the size of my palm. Ironically its not that venomous, unlike the vastly smaller bark scorpion, but your brain doesn’t process it that way. We showed it the door.

Now on @sciam.bsky.social: A recent paper in the high-profile journal Nature claimed what would've been an epochal revision to our understanding of the cosmos. Instead, independent follow-up work suggests the claim is wrong via a subtle-but-basic mistake. www.scientificamerican.com/article/phys...

Physicist says splashy new cosmology study made ‘elemental’ mistake

A recent study in the journal Nature carries cosmos-quaking implications for our understanding of the universe—except a new preprint says that it’s wrong

OK, it's one thing to see a science abstract that is far beyond my expertise, but not an abstract in astrophysics that doesn't even seem to be about any science. And who would read this abstract and say, "Oh, yeah! I'm really gonna have to drop what I'm doing and read this one!"

What did the early Universe *sound* like. With nice work by Stephane Pigeon who runs mynoise.net, we now have this nice "sonification" of the acoustic noise at the time of recombination. Have a listen! (and use headphone with the "wide" stereo setting. mynoise.net/NoiseMachine...

Sound Horizon — A Sonification of the Early Universe

Listen to the echoes of the early Universe. Explore a sonification of Planck satellite data and the primordial acoustic peaks frozen in the Cosmic Microwave Background.
