Color--Mass-to-Light Ratio Relations for Disk Galaxies
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…
Radial Acceleration Relation in Rotationally Supported Galaxies.
TLDR
A correlation between the radial acceleration traced by rotation curves and that predicted by the observed distribution of baryons is reported, tantamount to a natural law for rotating galaxies.
THE BARYON CONTENT OF COSMIC STRUCTURES
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…
Weighing Galaxy Disks with the Baryonic Tully-Fisher Relation
We estimate the stellar masses of disk galaxies with two independent methods: a photometrically self-consistent color$-$mass-to-light ratio relation (CMLR) from population synthesis models, and the…
Color evolution from z = 0 to z = 1
Rest frame Stroemgren photometry (3500 A, 4100 A, 4750 A, and 5500 A) is presented for 509 galaxies in 17 rich clusters between z = 0 and z = 1 as a test of color evolution. Our observations confirm…
One Law To Rule Them All: The Radial Acceleration Relation of Galaxies
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 types. We consider (i)…
The structure of brightest cluster members. I: Surface photometry
La photometrie de surface des galaxies elliptiques brillantes dans les cœurs des amas de galaxies, combinee a la photometrie tiree de la litterature, a permis de constituer un echantillon de 261…
The structure of brightest cluster members. II - Mergers
Surface photometry of 342 bright elliptical galaxies in 103 clusters is analyzed for evidence of mergers. Structural differences between brightest cluster members (BCMs) and normal ellipticals can be…
THE SUPERMASSIVE BLACK HOLE MASS-SPHEROID STELLAR MASS RELATION FOR SÉRSIC AND CORE-SÉRSIC GALAXIES
We have examined the relationship between supermassive black hole mass (M{sub BH}) and the stellar mass of the host spheroid (M{sub sph,*}) for a sample of 75 nearby galaxies. To derive the spheroid…
The Small Scale Environment of Low Surface Brightness Disk Galaxies
We use a sample of about 340 low surface brightness (LSB) disk galaxies with measured redshifts in combination with the Center for Astrophysics redshift survey to test the hypothesis that LSB…
