Major props to Francisco for ushering this through acceptance. A non-trivial task for anything that touches MOND phenomenology. The final version really highlights how the RAR may distinguish some modified gravity models from dark matter. In particular: hooks!🪝

The plot that triggered this verbatim comment: All-time combined spending on NASA, across 65 years of budgets, after adjusting for inflation, is less than the last three years of Pentagon budgets. All-time combined NASA spending in RY$ is less than 1 year of Pentagon spending.

Proud of this new paper led by UCI Physics & Astro PhD student Courtney Klein Courtney Klein - compares ‘true’ stellar mass-size relations to those inferred from mock observations w FIRE simulations. Pic shows mass map, light map & M/L map for example gal (1/3) arxiv.org/abs/2404.02373

Here's a closeup of the bright prominence that many people reported seeing with their naked eye during the eclipse. This was captured using two telescopes- at 2000mm and at 3650mm. These prominences are part of the solar chromosphere, and normally require a specially modified

Major congrats to 3rd yr UCI Physics & Astro PhD student Victoria Knapp Pérez on her LEAD Graduate Student Excellence Award - born & raised in Mexico City, w/ physics degree from NAU, she already has 3(!) published papers in particle physics theory ps.uci.edu/news/3081

Thrilled to share I'm now a full Professor in astronomy! Being the first US-born Latina to attain this is deeply meaningful to me. Grateful for the support along the way. Excited to pay it forward. Pa'lante!

A tenured UC Irvine professor (of global studies) is being arrested for protesting alongside students: “We cannot have a genocidal foreign policy in a democracy.”

Check out this astrobites article that highlights my most recent work!! 🙌🏼 Many thanks to Jack Lubin for making this happen.

Paper Day! arxiv.org/abs/2506.15785; “How invisible stellar halos bias our understanding of ultra-faint galaxies” In Wheeler+2019, we speculated that observed UFDs might be the bright central cores of more extended objects, and may have invisible stellar halos. (1/5)
