Geometrically Derived Timescales for Star Formation in Spiral Galaxies
D. Tamburro, H. -W. Rix, F. Walter +4
We estimate a characteristic timescale for star formation in the spiral arms of disk galaxies, going from atomic hydrogen (HI) to dust-enshrouded massive stars. Drawing on high-res…
Are the kinematics of DLAs in agreement with their arising in the gas disks of galaxies?
Martin Zwaan, Fabian Walter, Emma Ryan-Weber +3
We demonstrate in this paper that the velocity widths of the neutral gas in Damped Ly Alpha (DLA) systems are inconsistent with these systems originating in gas disks of galaxies s…
The HI content of star-forming galaxies at z = 0.24
Philip Lah, Jayaram N. Chengalur, Frank H. Briggs +12
We use observations from the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of star-forming galaxies at z = 0.24 (i.e. a look-backtime of ~3 Gyr)…
The Star Formation Threshold in NGC 6822
WJG de Blok, F Walter
We investigate the star formation threshold in NGC 6822, a nearby Local Group dwarf galaxy, on sub-kpc scales using high-resolution, wide-field, deep HI, Halpha and optical data. I…
The Baryonic Tully Fisher Relation
Sebastian Gurovich, Stacy S. McGaugh, Ken C. Freeman +3
We validate the baryonic Tully Fisher (BTF) relation by exploring the Tully Fish er (TF) and BTF properties of optically and HI-selected disk galaxies. The data includes galaxies f…
Star Formation in HI Selected Galaxies I: Sample Characteristics
J. F. Helmboldt, R. A. M. Walterbos, G. D. Bothun +2
A sample of 69 galaxies with radial velocities less than 2500 km/s was selected from the HI Parkes All Sky Survey (HIPASS) and imaged in broad band B and R and narrow band H-alpha…
