Tomorrow I'll be teaching my first ever class as a full-time professor! Syllabus available? ✅ Learning management system live? ✅ HW assigned for Week 1? ✅ #AcademicTwitter #AcademicChatter #BackToSchool #education

The 1st week of classes felt like a whole month, but it went better than expected overall. Getting to know students is always the best part of the semester! To top it off, my headshot is officially up on the department website (taken right after the first class on Monday)

Had a real "Can't believe I get paid for this!" moment in class today when showing students how to observe through #telescopes 😁 #astronomy #education #AcademicTwitter

Busy cosmologists, astrophysicsts and astronomers: Do you have 1 hr/ 2 weeks to #mentor and supervise motivated Centralamerican and Caribbean students? If yes, please fill the form (available in English), it will take you less than 10min! Astro Centroamérica y del Caribe astro.alphacen.org/en/programa-de…

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** Check INSPIRE HEP page: inspirehep.net/seminars/26255… 1/

Know anyone looking for undergraduate research opportunities in Astrophysics? We're launching a new program at UIUC: IDEAS (Illinois Developing Equity in Astrophysics Summer school) publish.illinois.edu/astroideas/

New HLSP: LOWLIB (Pal et al. 2023), a Low Resolution Stellar Library of 513 HST STIS spectra - flux calibrated, dereddened, and rest-frame corrected. Each star is observed with 3 gratings and merged into one continuous spectrum (0.2-1 micron at R ~1000). archive.stsci.edu/hlsp/lowlib

I’m quite used to the cruelty students can face when they apply for a US visa but this one broke me. We offered admission to a stellar, talented & hardworking student. After months of work and hundreds of dollars, an embassy officer saw him for 5 mins & said no. why? …

New Image of the Crab Nebula (supernova remnant) captured by #JWST. Perfect timing as I'm teaching about neutron stars and pulsars this week 😄

In honor of the new year, a 🧵on exciting directions for cosmology in 2024: 1. non-perturbative QFT in dS <-> cosmological signals Recent results on QFT in pure dS have been connecting the spectrum of operators and operator dimensions to new kinds of cosmic signals

Cosmology in 2025 will be really exciting so I put together a ‘Top 2025 Cosmology Papers I’m Looking Forward To’. Ordered from nearest to furthest, and guessing a bit on when they’ll come out. A fun 🧵

Indentured servants from abroad huh. That's one way to put it

Amazing work by NASA and Duke Physics's Michael A. Troxel on the OpenUniverse simulations. We are using these to get ready for Nancy Grace Roman Space Telescope! Check out the movies in here! nasa.gov/universe/new-s…

Elon Musk: It is thanks to you the future of civilization is assured. Meanwhile the US withdraws from the Paris Agreement AGAIN!

PSA: when a collaboration whose name starts with DE says they have found evidence for non-standard dark energy, the community should take that interpretation with more skepticism. DESI does not show that w0wa explains there data. Eg neutrino mass remains negative even with w0wa
