YCAA prize fellow at Yale. PhD from Princeton; headed to Stanford in 2025 as a Kavli fellow. I use large surveys of dwarf galaxies to disentangle the roles that star formation, stellar pop. assembly, and DM structure play in governing galaxy evolution.

Around one week left to register for Galactic Frontiers II -- looking forward to discussing low-mass galaxies with a great group this June! #astro #extragalactic

Saw this cool work on the arxiv today from Blake Keith & @ferahm.bsky.social! A demonstration of how the 3D shapes of stars trace that of DM in cosmologically simulated dwarfs, including a comparison to observed stellar shapes from my previous work. arxiv.org/abs/2501.16317 🔭 #extragalactic

Was psyched that Andrew Pace's Local Volume Database of dwarfs & star clusters was on ArXiV the other day! The push for community-facing collation is great to see in the #extragalactic space. (🔭) 📝 arxiv.org/abs/2411.07424 💻 github.com/apace7/local...

On ApJ now so technically an #extragalactic #astro #paperday! We deconvolve survey selection from evolution of the low-mass SFS at z<0.2. This constrains models of dwarf assembly, and signals how care is needed to use low-z galaxies to contextualize the LV/LG. ui.adsabs.harvard.edu/abs/2024ApJ....

For the dwarf galaxy enthusiasts in #astro & #extragalactic! Excited to share the conference we'll be hosting June 2025: 🔎 Galactic Frontiers II: Dwarfs in the LV & Beyond 🔎 6/23-6/25 at Dartmouth Note that the conference is NOT region-specific! Register at: sites.dartmouth.edu/galactic-fro...

And in the second Merian 🦋 paper out today: Princeton student Abby Mintz develops methods to turn medium-band imaging into Hα maps, and shows that low-mass starbursts tend to be more compact than their more massive counterparts. Read the paper here! arxiv.org/abs/2410.01886

So excited to share the first two science papers of the Merian medium-band survey! 🦋 We image Hα and [OIII] to measure weak lensing and resolved star formation in low-z dwarfs over ~750 deg^2. Check out the survey paper led by Shany Danieli at: arxiv.org/abs/2410.01884 !

Excited to see this very nice research highlight of our recent quenched field dwarf paper by @aasnova.bsky.social !

Paper day! arxiv.org/abs/2401.16469 We use the background galaxies in the SAGA survey to infer the efficiency of winds driven by star formation in low-mass galaxies. We find a mass-loading factor of ~1: consistent with direct observations, but smaller than what some sims predict at these masses.

A late ArXiV post since I wasn’t active here — we present a field dwarf pair where one is starbursting and the other is *quenched*! VLA data reveal that the non-SF dwarf's HI is in large tidal tails, showing that field dwarfs can temporarily quench even as non-satellites. arxiv.org/abs/2311.09280
