MOND Prediction for the Velocity Dispersion of the `Feeble Giant' Crater II
Stacy S. McGaugh
Crater II is an unusual object among the dwarf satellite galaxies of the Local Group in that it has a very large size for its small luminosity. This provides a strong test of MOND,…
The candidate cluster and protocluster catalog (CCPC) II: Spectroscopically identified structures spanning 2 < z < 6.6
J. R. Franck, S. S. McGaugh
The Candidate Cluster and Protocluster Catalog (CCPC) is a list of objects at redshifts z > 2 composed of galaxies with spectroscopically confirmed redshifts that are coincident on…
One Law To Rule Them All: The Radial Acceleration Relation of Galaxies
Federico Lelli, Stacy S. McGaugh, James M. Schombert +1
We study the link between baryons and dark matter in 240 galaxies with spatially resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all morphological type…
The Radial Acceleration Relation in Rotationally Supported Galaxies
Stacy McGaugh, Federico Lelli, Jim Schombert
We report a correlation between the radial acceleration traced by rotation curves and that predicted by the observed distribution of baryons. The same relation is followed by 2693…
The Relation between Stellar and Dynamical Surface Densities in the Central Regions of Disk Galaxies
Federico Lelli, Stacy S. McGaugh, James M. Schombert +1
We use the SPARC (Spitzer Photometry & Accurate Rotation Curves) database to study the relation between the central surface density of stars Sstar and dynamical mass Sdyn in 135 di…
SPARC: Mass Models for 175 Disk Galaxies with Spitzer Photometry and Accurate Rotation Curves
Federico Lelli, Stacy S. McGaugh, James M. Schombert
We introduce SPARC (Spitzer Photometry & Accurate Rotation Curves): a sample of 175 nearby galaxies with new surface photometry at 3.6 um and high-quality rotation curves from prev…
