The Cosmology Researcher Talks database hit a milestone today of 10,000 links to publicly available talk/lecture videos, data from 212 sources. 2020s avg is 1,218 /yr. A fun project & a good way for me to learn more, I'm pleased if it's useful to you. https://t.co/qkaJmWjS5U

Flourless chocolate cake, panna cotta, Irish coffees, plus a view of the fireplace from where we sat. Panna cotta was a 4-inch diameter 1/4" thick slice topped with goodies.

Astrophysicist @david_kipping reviews learnings from an AI in science meeting at the Institute for Advanced Study in Princeton. It was so impactful he felt compelled to share it in this clear, focused, thoughtful talk. Topic timestamp links available in the Description section.
I attended a meeting last week that was one of the most shocking of my career. Here’s the low down https://t.co/JCHDpNvePV

Interested in knowing more about GW231123 as a potential gravitational-lensing candidate? My talk w/ @just_shaun covers evidence for magnification and diffraction, implications for source properties, and dark matter. ▶️

Tried out this new Confer encrypted AI chat offering today, 32-byte encryption based on passkeys, so no login password involved. Excellent article by Dan Goodin. A few intro articles at the Confer blog: https://t.co/MWztiJaXRD So far I like it and intend to use it.

Pleasant surprise - TIFR hadn't posted anything to their State of the Universe seminars site since early 2025, but today they posted all their seminar videos since then. https://t.co/O3oEQxCV6S

Just saw that CHIME now reports a 21 cm intensity mapping signal in autocorrelation https://t.co/2nfHzhC8gk Wondering if you or others have any comments about this new paper.
arxiv.org
We present the first detection of the cosmological 21 cm intensity mapping signal in auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Using 94 nights of...
@nu_phases This is not the first detection I'm afraid -- GBT and Parkes both obtained similar (cross-correlation) detections several years ago. No experiment has yet detected it purely in autocorrelation.
