Can anyone explain to me why I am seeing "trump is speaking" as the banner even though no one I follow is likely to be wanting to see this nearly 100 count indicted man speak? And why is it always Mr. musk's face as the first person shown next to it?
Well that's it for #northeast_dwarfs. I'm full of great dwarf galaxy ideas and results. Thanks Alyson Brooks, @DanieliShany, @bmutlupakdil, and @erin_kadofong for organizing such an exciting group of people, and @FlatironInst for hosting!
J Mead at #northeast_dwarfs tells us all about intrinsic scatter in dwarf galaxies from APOGEE and the zillions of different elements it has. Lots there especially when compared to GCs!
At #northeast_dwarfs @DanieliShany shows some really neat results from the ELVES survey particularly focusing on (but not only!) how it constrains the stellar to halo mass relation in the classical dSph mass regime
I'm biased as a team member, but I think @mgeha gave a fantastic overview of the SAGA survey at #northeast_dwarfs especially now that we've got all the data! Lots of good stuff but s lot was preliminary so I'll just say "paper soon"
R Cohen at #northeast_dwarfs shows us how powerful HST can be to prove age gradients in dwarf galalxies (even just from the archive!) and how that constrains galaxy formation models
C Carr at #northeast_dwarfs tells us how, using population level studies, there are multiple approaches to feed ack that currently work but make different hot CGM predictions
Really thorough and fantastic datasets on low metallicity massive stars in G Telford's talk at #northeast_dwarfs. I thought it especially neat (surprising?) how well the Leo P O star fit the CLOUDY models that have never been tested at so low a metallicity.
A Brooks at #northeast_dwarfs gives an excellent overview of the Marvelous and Justice League sims and in particular what predictions the feedback makes for dwarf galaxies. Particular props to the work to do a fair comparison to FIRE (Sorry for the soft focus on the slide!)
A...maze...ing data from @sdssurveys APOGEE on classical dSphs from @rareflwr41 at #northeast_dwarfs. Want "comparative dwarfology"? Soon we'll all have it.
At #northeast_dwarfs @annafrebel describes some very low metallicity stars and traces them back to very early accretion events for the milky way (and multiple slightly tortured acronyms! 😉)
Great very energetic talk by @alexanderpji at #northeast_dwarfs on Ret II and how you can measure its gas dynamics from like 10 Gyr ago using r process elements' dispersion
Great talk by @bmutlupakdil at #northeast_dwarfs on NGC 253/Sculptor's dwarf galaxy population and the amazing nearby dwarf potential discovery space in Rubin's LSST at similar distances.
J Greene gives a talk at #northeast_dwarfs of some amazing plausible red AGNs in the UNCOVER @NASAWebb survey. Lots of exciting implications for black hole formation (although lots of discussion that some confirmation still needed... But coming very soon!)
S Gezari at #northeast_dwarfs gives a great overview of tidal disruption events and how they are especially sensitive to black holes in dwarf galaxies. And a tentative first few detections of white dwarfs undergoing thermonuclear explosion while TDEing! (Look like SNe Ia)
J Bellovary gives a great overview of black holes in dwarf galaxies as the first talk in day two of #northeast_dwarfs, particularly the puzzle of off-centered BHs (spoiler: it's dark matter cores!)
We're now entering a short-talk phase od #northeast_dwarfs so probably can't keep up with them. But still lots of cool stuff on nearby dwarf galaxies and dark matter
J Wadekar at #northeast_dwarfs shows a great demonstration on using gas rich faint dwarf galaxies as a *new* (colorimetric) kind of dark matter detector
T Nguyen at #northeast_dwarfs shows a neat proof of concept of using normalizing flows and simulation based inference to do dynamical modeling of dwarf galaxies and their dark matter profiles
