Central galaxies in different environments: Do they have similar properties?
Ivan Lacerna, Aldo Rodriguez-Puebla, Vladimir Avila-Reese +1
We perform an exhaustive comparison among central galaxies from SDSS catalogs in different local environments at 0.01<=z<=0.08. The central galaxies are separated into two categori…
The clustering of ALFALFA galaxies: dependence on HI mass, relationship to optical samples & clues on host halo properties
Emmanouil Papastergis, Riccardo Giovanelli, Martha P. Haynes +2
We use a sample of ~6000 galaxies detected by the Arecibo Legacy Fast ALFA (ALFALFA) 21cm survey, to measure the clustering properties of HI-selected galaxies. We find no convincin…
The Massive Satellite Population of Milky-Way Sized Galaxies
A. Rodriguez-Puebla, V. Avila-Reese, N. Drory
Several occupational distributions for satellite galaxies more massive than ms~4E7 Msun around MW-sized hosts are presented and used to predict their internal dynamics. For this, a…
The Galaxy-Halo/Subhalo connection: Mass relations and implications for some satellite occupational distributions
A. Rodriguez-Puebla, V. Avila-Reese, N. Drory
We infer the local stellar-to-halo/subhalo mass relations (MRs) for central and satellite galaxies separately. We constraint this relations by using several combinations of observa…
