So happy to see Dr. Raga Pucha's awesome work on identifying black holes (and candidates) in low-mass galaxies using the DESI data!
‘Vast discovery’ of black holes in dwarf galaxies - @theU
New U-led research from the Dark Energy Spectroscopic Instrument reveals 300 new intermediate-mass black holes and 2,500 dwarf galaxies with active black holes, tripling the existing census for both.

Excited about this press release on Raga's great work finding elusive intermediate-mass black holes in galaxies! This project started during her PhD. Nice to see it come to fruition & also a glimpse of what the future holds with now much more DESI data in hand 🤩🔭

It was really nice to come back to Pittsburgh to see friends and talk about the SAGA Survey.

Heard a cool talk by @yymao.bsky.social today about the SAGA Survey! Learned a lot about satellites of MW-like galaxies, but I was personally most excited about the neat visualizations from the data release paper (arXiv:2404.14498) and the "poster" paper summaries on the website (sagasurvey.org).

It's very fitting that my first post here is about this important milestone for the SAGA Survey and for myself personally!

The SAGA Survey characterizes satellite galaxy systems around Milky Way-mass galaxies, and we just posted our major results from our Data Release 3! Check arXiv & our website!

This is a really rich analysis and data set, made possible by Elise Darragh-Ford, @yymao.bsky.social, Risa Wechsler, @jegpeek.bsky.social, and many others!

You can now access some of the data from the the DESI Early Data Release. Stay tuned for even more!
