... The process of proposing for Hubble Space Telescope observing time has been revised, to make it simpler for proposers. We describe the simple, flexible, and robust prototype system created to handle proposal submission. ... Proposing for Hubble Space Telescope ( HST ) observing time proceeds in two phases: the scientific merits of the proposal are considered in Phase I; only accepted proposals enter Phase II, where the observations are described in complete detail. ...

... Neutral hydrogen is the best tracer of accreting and outflowing gas, however very hard to detect due to its low column density. ... Simulations predict that in order to detect HI in the extended environment of galaxies, brightness sensitivities well below NHI ~1018 cm-2 are required (e.g. Popping et al. ... Direct aims of the projects include: - Achieve a 1 sigma NHI of 2.5x1017 cm-2 over 20 km/s. - Measure the extended gas content of galaxies to detect gas accretion and outflows. ...

... Partner Recommended Time: . ... Time Requested in this Proposal: . ... Abstract: The primary aim of this proposal is to determine accurate distances to two Extreme Gas-Rich Dwarfs selected by Blind 21cm Line surveys. These two galaxies are representative of a galaxy class with an apparent large HI gas mass fraction, which may be vastly under-represented in conventional catalogs. ... Thus it is crucial to find an independent distance estimator for at least a sub-sample of these galaxies. ... Time . ...

... Following the full moon on Monday, March 24, I was able to make use of a few brief periods totalling about an hour and a half before the Easter weekend to make some 160 galaxy observations at home in Coonabarabran using the 0.41m telescope. ... Because of being on holidays my resources for comparison purpouses were rather limited, and so I had to rely upon amateur contacts in Queensland to verify my memory of this galaxy, and also to obtain visual confirmation of the supernova. ...

Apache 1.1 and earlier let modules handle POST and PUT requests by themselves. The module would, on its own, determine whether the request had an entity, how many bytes it was, and then called a function ( read_client_block ) to get the data. ... This step also sends a 100 Continue response to HTTP/1.1 clients, so should not be called until the module is *definitely* ready to read content. (otherwise, the point of the 100 response is defeated). ... Finally, call ap_get_client_block in a loop. ...
