H II region abundances - Model oxygen line ratios
- S. McGaugh
- Physics
- 1 October 1991
An extensive, homogeneous grid of H II region models, is presented. It is found that the behavior of the strong oxygen lines can be modeled by taking proper account of the softening of the ionizing… Expand
THE BARYONIC TULLY-FISHER RELATION OF GAS-RICH GALAXIES AS A TEST OF ΛCDM AND MOND
- S. McGaugh
- Physics
- 14 July 2011
The baryonic Tully-Fisher relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in ΛCDM and of… Expand
SPARC: Mass Models for 175 Disk Galaxies with Spitzer Photometry and Accurate Rotation Curves
- F. Lelli, S. McGaugh, J. M. S. C. W. R. University, U. Oregon
- Physics
- 29 June 2016
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 previous HI/Halpha… Expand
THE BARYONIC TULLY-FISHER RELATION OF GALAXIES WITH EXTENDED ROTATION CURVES AND THE STELLAR MASS OF ROTATING GALAXIES
- S. McGaugh
- Physics
- 30 June 2005
I investigate the baryonic Tully-Fisher relation for a sample of galaxies with extended 21 cm rotation curves spanning the range 20 km s-1 Vf ? 300 km s-1. A variety of scalings of the stellar… Expand
Color--Mass-to-Light Ratio Relations for Disk Galaxies
- S. McGaugh, J. Schombert
- Physics
- 7 July 2014
We combine Spitzer $3.6\mu$ observations of a sample of disk galaxies spanning over 10 magnitudes in luminosity with optical luminosities and colors to test population synthesis prescriptions for… Expand
Modified Newtonian dynamics as an alternative to dark matter
- R. Sanders, S. McGaugh
- Physics
- 30 April 2002
▪ Abstract Modified Newtonian dynamics (MOND) is an empirically motivated modification of Newtonian gravity or inertia suggested by Milgrom as an alternative to cosmic dark matter. The basic idea is… Expand
Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions
- B. Famaey, S. McGaugh
- Physics, Medicine
- Living reviews in relativity
- 16 December 2011
A wealth of astronomical data indicate the presence of mass discrepancies in the Universe. The motions observed in a variety of classes of extragalactic systems exceed what can be explained by the… Expand
Radial Acceleration Relation in Rotationally Supported Galaxies.
- S. McGaugh, F. Lelli, J. Schombert
- Physics, Medicine
- Physical review letters
- 19 September 2016
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 points in 153… Expand
OXYGEN ABUNDANCES IN LOW SURFACE BRIGHTNESS DISK GALAXIES
- S. McGaugh
- Physics
- 25 November 1993
The oxygen abundances in the \HII regions of a sample of low surface brightness (LSB) disk galaxies are presented. In general, LSB galaxies are found to be metal poor ($Z < {1 \over 3} Z\solar$).… Expand
THE BARYON CONTENT OF COSMIC STRUCTURES
- S. McGaugh, J. Schombert, W. D. Blok, Matthew J. Zagursky
- Physics
- 13 November 2009
We make an inventory of the baryonic and gravitating mass in structures ranging from the smallest galaxies to rich clusters of galaxies. We find that the fraction of baryons converted to stars… Expand
