The Third Law of Galactic Rotation
Stacy S. McGaugh
I review the connection between dynamics and the baryonic mass distribution in rotationally supported galaxies. The enclosed dynamical mass-to-light ratio increases with decreasing…
Stellar Populations and the Star Formation Histories of LSB Galaxies: III. Stellar Population Models
James Schombert, Stacy McGaugh
A series of population models are designed to explore the star formation history of gas-rich, low surface brightness (LSB) galaxies. LSB galaxies are unique in having properties of…
Color--Mass-to-Light Ratio Relations for Disk Galaxies
Stacy McGaugh, Jim Schombert
We combine Spitzer observations of a sample of disk galaxies spanning over 10 magnitudes in luminosity with optical luminosities and colors to test population synthesis pres…
Co-orbiting planes of sub-halos are similarly unlikely around paired and isolated hosts
Marcel S. Pawlowski, Stacy S. McGaugh
Sub-halos in dark-matter-based cosmological simulations tend to be distributed approximately isotropically around their host. The existence of highly flattened, co-orbiting planes…
A Tale of Two Paradigms: the Mutual Incommensurability of LCDM and MOND
Stacy S. McGaugh
The concordance model of cosmology, LCDM, provides a satisfactory description of the evolution of the universe and the growth of large scale structure. Despite considerable effort,…
Perseus I and the NGC 3109 association in the context of the Local Group dwarf galaxy structures
Marcel S. Pawlowski, Stacy S. McGaugh
The recently discovered dwarf galaxy Perseus I appears to be associated with the dominant plane of non-satellite galaxies in the Local Group (LG). We predict its velocity dispersio…
