🔭🧪 Paper day! I’m really excited about this one. We used simulations of Milky Way-like galaxies simulated with full cosmic ray spectra to model gamma-ray emission. The simulated galaxies form large gamma-ray bubbles with remarkable similarities to the Fermi bubbles observed in the Milky Way.

Paper day! We used MHD galaxy formation simulations with multi-species cosmic ray spectra to model diffuse gamma-ray emission in Milky Way analogs. This allows us to see how gamma-ray flux changes due to star formation, ISM structure, B fields, etc. over time. arxiv.org/pdf/2509.18351

This is what amounts to an ILLEGAL & indiscriminate funding cut for research centers everywhere. It will mean shuttering labs across the country, layoffs in red & blue states, and derailing lifesaving research on everything from cancer to opioid addiction.
We all need to speak out to save lives.

Excited and honored to have the opportunity to share the recent work I led at #dwarfgalaxies2024 !
#dwarfgalaxies2024 using FIRE Isabel Sands suggests HI rotation curves are not a good representation of DM halo profiles due to time dependence and extra pressure terms, resulting in artificially diverse RCs. arxiv.org/abs/2404.16247
