Coming to arxiv tomorrow...

My review/lecture notes on axion dark matter are up on the arxiv today! They serve as an introduction to topics such as axion production mechanisms, cosmological bounds, and indirect detection. Here are some of the figures: arxiv.org/abs/2403.17697

Breaking news: the Event Horizon Telescope team unveils strong magnetic fields spiraling at the edge of Milky Way’s central black hole, Sagittarius A*. This new image suggests that strong magnetic fields may be common to all black holes. #OurBlackHole #SgrABlackHole

🥇🚨Gold alert – IceCube observation of a high-energy neutrino candidate event at 2024/03/27 11:04:49 UTC. Find out more at gcn.nasa.gov/circulars/35983.

Last minute postdoc position in our awesome group! academicjobsonline.org/ajo/jobs/27447

Honored to be selected as a 2024 Emmy Noether Visiting Postdoctoral Fellows. Looking forward to collaborating with colleagues at Perimeter Institute! #physics #science #EmmyNoether #PerimeterInstitute perimeterinstitute.ca/news/meet-2024…

🔔📜 IceCube paper submitted to PRL! We present neutrino oscillation results using one of the largest GeV neutrino samples in the world and an advanced reconstruction method. The results are the most precise to date using atmospheric neutrinos. Story ➡️ icecube.wisc.edu/news/research/…

It's paper day! With Dan Hooper and Anastasia Sokolenko we looked into synchrotron emission from the Geminga halo using Planck data arxiv.org/abs/2405.06739

We are organizing a workshop in New York City to discuss how to combine numerical simulations with machine learning techniques to improve our knowledge of cosmology and galaxy formation. If you are interested in attending, please register here events.simonsfoundation.org/event/51977633…

BU cosmology/high-energy theory is hiring a postdoc! We're interested in candidates working on high-energy theory and/or cosmology and astroparticle physics, broadly construed. Please contact me for more info! academicjobsonline.org/ajo/jobs/28836

Filaments thread the cosmos together, yet their properties and evolution remain uncertain.
