نویسندگان
چکیده
The interstellar gas in spiral galaxies can constitute a significant fraction of the baryon mass and it has been demonstrated that sum stellar components correlates well with kinematic signature total content, widths HI line profiles. correlation baryonic is used here to obtain distances for 9984 extending ~0.05c. sample flux limited correction required account an selection bias. absolute scale established by 64 known from studies Cepheid variables and/or magnitudes stars at tip red giant branch. calibration relationship results determination Hubble constant H_0=75.5+-2.5 km/s/Mpc. error estimate statistical. This material will be combined contributions other methodologies subsequent article where systematic uncertainties investigated.

The Baryonic Tully-Fisher Relation.
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 m...
متن کاملThe Baryonic Tully - Fisher relation revisited
The Baryonic Tully-Fisher relation (BTF) can be substantially improved when considering that the galactic baryonic mass is likely to consist not only of the detected baryons, stars and gas, but also of a dark baryonic component proportional to the HI gas. The BTF relation is optimally improved when the HI mass is multiplied by a factor of about 3, but larger factors up to 11 − 16 still improve ...
متن کاملPfam 10 years on: 10 000 families and still growing
Classifications of proteins into groups of related sequences are in some respects like a periodic table for biology, allowing us to understand the underlying molecular biology of any organism. Pfam is a large collection of protein domains and families. Its scientific goal is to provide a complete and accurate classification of protein families and domains. The next release of the database will ...
متن کاملThe effects of baryonic cooling on the concentration–mass relation
I re-examine the relation between virial mass and concentration for groups and clusters of galaxies as measured in a number of recent works. As previously noted by several authors, lowmass clusters and groups of galaxies display systematically larger concentrations than simple prescriptions based on pure N-body simulations would predict. This implies an observed concentration–mass relation with...
متن کاملEducating 10, 000 informaticians by 2010: The AMIA 10 × 10 program
Objectives: There is an increasing need for a larger and better trained workforce in medical informatics. The goal of the American Medical Informatics Association 10×10 program is to educate 10,000 clinicians in medical informatics by the year 2010. Methods: We adapted an on-line introductory graduate course toward this goal. It was evaluated using Likert-scale and open-ended questions. Results...
