On the Dichotomy between Normal and Dwarf Ellipticals
James M. Schombert
Using images from the SDSS DR13 library, we examine the structural properties of 374 bright (classed E0 to E6) and dwarf ellipticals (classed dE(nN) to dE(N)). The sample combines…
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…
Colors of Ellipticals from GALEX to Spitzer
J. Schombert
Multi-color photometry is presented for a large sample of local ellipticals selected by morphology and isolation. The sample uses data from GALEX, SDSS, 2MASS and Spitzer to cover…
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…
