It's time to resume the #LoopyTuesday posts, as today the new @ilqgs season started: we had Mauricio Gamonal from @PennState telling us about how to compute next-to-leading order terms in cosmology, a way to close the gap between EFT and quantum gravity. https://t.co/yX5z60s3ck
The Center for SpaceTime and the Quantum is inviting applications for the Enrico Fermi Fellowships (visit https://t.co/4GfV0lx0OT), an initiative funded by @templeton_fdn, for grad students pursuing research across the theory/experiment divide.
Deadline: Oct 16 2024, 12 AM CET
In eight new papers, @NANOGrav presents evidence for a gravitational wave background. In this bite, we provide an overview of their results and their implications #pulsartimingarrays#GravitationalWaves

Got word yesterday that Stanley Deser, one of the giants of relativity, passed away. He is the D of ADM, contributed to foundational work in supergravity, showed 1-loop renormalizability of GR+Maxwell, and so much more. May his memory be a blessing
We are at the precipice of the Big Data Gravitational Wave Era 👇 The discoveries we will be able to make in ~10-20 years with @CosmicExpGW (CE) and #EinsteinTelescope (ET) will completely dwarf the ~100 detections seen so far... 🤩📈 1/8
Nuestra vocera @karliverits en @latercera:“La forma en que está planteada la beca es absurda, porque ni siquiera te exige trabajar en Chile. Te pide sólo residir físicamente en Chile. O sea, puedes volver, mirar el techo y eso significa retribución. Hay algo que está mal pensado”
There are some very prominent non-cosmologists who, when talking to the public, insist on talking about the "Big Bang" as the Universe's beginning.
It's not.
It's a hot, dense, early state, but can't be the very beginning.
In ~8 hours, I'll show you the observational proof.
New cosmology resource materials app => searchable cross-reference of arXiv papers for which online researcher talks exist
If you ever want to know if a researcher talk is available for a particular paper, this could be a handy app

Dear colleagues,
Cosmology Talks will be hosting a mini-workshop on Wednesday February 1 at 18:00 UTC on
**ultralight axions, cosmological tensions, and structures in the very early universe**

@VergaraLautaro Inspiring! During the #Loops22 conference last year I heard his story for the first time. The Loop Quantum Gravity community has a prize named after him: https://t.co/M5CbOgR3av
Horizons are watching you 👀
New paper with Bob Wald and @DaineDanielson. We show that horizons decohere quantum superpositions *as if* the superposition is being measured!
So, due to the cosmological horizon, the universe is always watching.

For those in need of holiday reading, watch for my TASI lectures on the arXiv next week.
Videos of the lectures are already available here

Ultracold atoms have been used to mimic a curved, expanding universe, revealing that it may be possible for pairs of particles to pop up out of empty space https://t.co/Kjw9cg4FAN
🔔New IceCube results to be published in @ScienceMag tomorrow!
For the first time, IceCube found evidence of high-energy neutrino emission from NGC 1068, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies. #IceCubeNGC1068
