We explore the Tully-Fisher relation over five decades in stellar mass in galaxies with circular velocities ranging over 30 less, similarVc less, similar300 km s-1. We find a clear break in the optical Tully-Fisher relation: field galaxies with Vc less, similar90 km s-1 fall below the relation defined by brighter galaxies. These faint galaxies, however, are very rich in gas; adding in the gas mass and plotting the baryonic disk mass Md=M*+Mgas in place of luminosity restores the single linear… Expand

THE BARYONIC TULLY-FISHER RELATION OF GALAXIES WITH EXTENDED ROTATION CURVES AND THE STELLAR MASS OF ROTATING GALAXIES
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 stellarExpand
The different baryonic Tully-Fisher relations at low masses.
TLDR
The Baryonic Tully-Fisher relation (BTFR) of simulations and observations of galaxies ranging from dwarfs to spirals, using various measures of rotational velocity Vrot is compared, highlighting the need for careful comparisons between observations and models. Expand
The H I Tully-Fisher relation of early-type galaxies
We study the H iK-band Tully-Fisher relation and the baryonic Tully-Fisher relation for a sample of 16 early-type galaxies, taken from the ATLAS3D sample, which all have very regular H i disksExpand
The low-mass end of the baryonic Tully-Fisher relation
The scaling of disc galaxy rotation velocity with baryonic mass (the ‘baryonic Tully–Fisher’ relation, BTF) has long confounded galaxy formation models. It is steeper than the M ∝ V3 scaling relatingExpand
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 theExpand
Baryonic Tully-Fisher relation for extremely low mass Galaxies
We study Tully-Fisher (TF) relations for a sample that combines extremely faint (M B < -14) galaxies along with bright (i.e. L.) galaxies. Accurate (∼10 per cent) distances, I-band photometry and B -Expand
A FIRST ATTEMPT TO CALIBRATE THE BARYONIC TULLY-FISHER RELATION WITH GAS-DOMINATED GALAXIES
We calibrate the baryonic Tully–Fisher (BTF) relation using a sample of gas-dominated galaxies. These determine the absolute scale of the baryonic mass–rotation speed relation independent of theExpand
Polar Ring Galaxies and the Tully-Fisher relation
We have investigated the Tully-Fisher relation for Polar Ring Galaxies (PRGs), based on near infrared, optical and HI data available for a sample of these peculiar objects. Many PRGs show larger HIExpand
THE BARYONIC TULLY-FISHER RELATIONSHIP FOR S4G GALAXIES AND THE “CONDENSED” BARYON FRACTION OF GALAXIES
We combine data from the Spitzer Survey for Stellar Structure in Galaxies, a recently calibrated empirical stellar mass estimator from Eskew et al., and an extensive database of H i spectral lineExpand
The baryonic Tully–Fisher relation and galactic outflows
Most of the baryons in the Universe are not in the form of stars and cold gas in galaxies. Galactic outflows driven by supernovae/stellar winds are the leading mechanisms for explaining this fact.Expand
