Gas and Stars in Galaxies - A Multi-Wavelength 3D Perspective (2008)
Lehnert, Matt, De Breuck, Carlos, Kuntschner, Harald, Zwaan, Martin
An overview of the ESO/Radionet workshop devoted to 3D optical/near-infrared and sub-mm/radio observations of gas and stars in galaxies is presented. There will be no published proceedings but...
Are the kinematics of DLAs in agreement with their arising in the gas disks of galaxies? (2008)
Zwaan, Martin, Walter, Fabian, Ryan-Weber, Emma, Brinks, Elias, Kennicutt Jr., Robert C.
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 similar to those...
European ALMA operations: the interaction with and support to the users (2008)
Andreani, Paola, Zwaan, Martin
The Atacama Large Millimetre/submillimetre Array (ALMA) is one of the largest and most complicated observatories ever built. Constructing and operating an observatory at high altitude (5000m) in a...
Are the kinematics of DLAs in agreement with their arising in the gas disks of galaxies? (2008)
Zwaan, Martin, Walter, Fabian, Ryan-Weber, Emma, Brinks, Elias, Kennicutt, Robert C.
We demonstrate in this paper that the velocity widths of the neutral gas in damped Lyalpha (DLA) systems are inconsistent with these systems originating in gas disks of galaxies, similar to those...

Normal Globular Cluster Systems in Massive Low Surface Brightness Galaxies (2007)
Villegas, Daniela, Kissler-Patig, Markus, Jordán, Andrés, Goudfrooij, Paul, Zwaan, Martin
We present the results of a study of the globular cluster systems of 6 massive spiral galaxies, originally cataloged as low surface brightness galaxies but here shown to span a wide range of central...
Hydrogen 21-Centimeter Emission from a Galaxy at Cosmological Distance (2001)
Zwaan, Martin, Van Dokkum, Pieter, Verheijen, Marc
We have detected the neutral atomic hydrogen (HI) emission line at a cosmologically significant distance (z=0.18) in the rich galaxy cluster Abell 2218 with the Westerbork Synthesis Radio Telescope....
Reconciling Damped Ly-alpha Statistics and 21cm Studies at z=0 (2001)
Zwaan, Martin, Briggs, Frank, Verheijen, Marc
Blind 21cm surveys in the local universe have shown that the local HI mass density, Omega_HI, is dominated by luminous, high surface brightness, spiral galaxies. On the other hand, surveys for host...
A Targeted Survey for HI Clouds in Galaxy Groups (2001)
Five galaxy groups with properties similar to those of the Local Group have been surveyed for HI clouds with the Arecibo Telescope. In total 300 pointings have been observed on grids of approximately...
The HI mass function in Ursa Major (2000)
Verheijen, Marc, Trentham, Neil, Tully, Brent, Zwaan, Martin
A deep blind HI survey of the nearby spiral rich Ursa Major cluster has been performed with the VLA in parallel with a wide-field R-band imaging campaign of most VLA fields with the CFHT. The goal is...
Zwaan, Martin, Verheijen, Marc, Briggs, Frank
We present a measurement of the HI column density distribution function, f(N), at the present epoch for column densities log N > 20 cm^-2. These high column densities compare to those measured in...
The Local HI Mass Function (1998)
The local HI mass function (HIMF), like the optical luminosity function, is an important observational input into models of cosmology and galaxy evolution. It is a helpful framework for assessing the...
The HI Mass Function of Galaxies from a Deep Survey in the 21cm Line (1997)
Zwaan, Martin, Briggs, Frank, Sprayberry, David, Sorar, Ertu
The HI mass function (HIMF) for galaxies in the local universe is constructed from the results of the Arecibo HI Strip Survey, a blind extragalactic survey in the 21cm line. The survey consists of...
