.@SheaGKosmo: Peebles spin parameter not a good predictor of glx morphology (e.g. disk fraction). Mass of gas in glx at z=0 is! #SCgal17
.@SheaGKosmo quantifies FIRE II ELVIS sims' morphology with the Jay z plot. But who is J-circ? #SCgal17
current and former #UCIPhysAstro galaxy formation-ers at #SCgal17. #noprofnoproblem #sorrytim @coralrosew @jbprime @MBKplus @Antithestasia
GuhaThakurta: M87 has "orphan" GCs out to ~100x its Reff. Velocities suggest 2 pops: M87 pop and "intracluster" pop. #SCgal17
No faculty? No problem! #anteaters on the last day of #SCgal17 #thenextgeneration #santacruz… https://t.co/0TZBNN13VC
Keres: Barys leave halos more easily than metals. Most metals ejected but mass/z-dep frac recycled back (more to CGM at late times) #SCgal17
This can have a drastic effect on infall times when compared to DMO sims w/o potential -> important for quenching timescales! #SCgal17
Tyler Kelley: analytic potentials + DMO cosmo sims -> enhanced subhalo destrct. Pots can be tailor-made & run w frac of comp time! #SCgal17
Tiffany Hsyu: discovered most metal poor SF glx (M*~10^5-10^6 Msun), possible gas-rich satellite of nearby spiral (dproj 70-90 kpc) #SCgal17
Andrew Graus: limited telescope coverage -> Gyr err in time dwf glx form 90% mass. Must use multiple fields around half-light rad. #SCgal17
.@coralrosew discusses her dwarf sims: highest resolution cosmological simulation ever run to z=0 #SCgal17
Alejandro Gonzalez-Samaniego shows that mass estimators work! #SCgal17
.@8minutesold discusses MW satellite distribution very different than LCDM subhalo predictions #SCgal17
.@jbprime shows @astronoliver's new results: Most ~10Msun BHs live in MWs, most ~30Msun BHs live in LMCs! 100 in Draco, 10^7 in mW! #SCgal17
Sean Fillingham introduces his ambitious Keck/DEIMOS program to study LMC-size satellite quenching at z~1 #SCgal17
.@cooperUCI shows nice work by @AstronoMouse_ : existing UFDs couldn't all have fallen in early enough 2B quenched by environment #SCgal17
.@cooperUCI: pretty much all satellite quenching models over-predict quenched fractions. Need to let observations lead the way. #SCgal17
Woo: sat quenching deps on group/cluster-cen dist, but only for lg Mhost, and on Mhost, but only for small group/cluster-cen dist #SCgal17
.@redshiftless: Distribution of accreting gas can be more important in setting galaxy properties (e.g sSFR) than z=0 halo mass. #SCgal17
