an absorption line sample of absorbing systems drawn from published works, we are able to study the relationship between gas and galaxies over the latter half of the age of the Universe. A correlation between absorbers and galaxies is detected out to separation of Mpc. This correlation is weaker than the galaxy-galaxy :// Journal: Young Galaxies and QSO Absorption-Line Systems, ASP Conference Series, Vol. , , ed. Sueli M.

We present results of an ongoing program to study the gaseous extent of galaxies and the origin of QSO absorption line systems. For \lya absorption systems, we find that absorption equivalent (2) At z less than or approximately = 1 the fraction of Ly(aplha) absorption systems-including Ly(alpha)-forest absorption systems-that arise in luminous galaxies is at least +/- and may

By studying the physical conditions in galaxies at different redshifts, we can begin to understand the evolutionary process of starformation from early epochs to the present. Such studies have been performed at optical and centimeter wavelengths for a number of years.
Due to advances in receiver and telescope technology at millimeter and submillimeter wavelengths, molecular line studies have W/abstract.

) Astronomical Society of the Pacific, We propose slitless spectroscopic observations with the FOC of two luminous star-forming galaxies at z~ to determine the amplitude of their intrinsic Lyman breaks.
The opacity to ionizing UV photons of even the closest starbursts, not to mention the Milky Way, remains highly uncertain and yet bears directly on such issues as the ionization source for the Lyman-alpha forest and other QSO CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Dwarf galaxies (DGs) are more numerous than large galaxies.
Most dwarfs in clusters are dEs, but in the field they belong mostly to late types. The importance of late-type DGs in the context of the intergalactic medium (IGM) lies in the fact that (at least some) are probably “young ” galaxies forming stars for the ?doi= Request PDF | On Jan 1,M.

The reason is that the elements of these species generally have high cosmic abundances and the transitions involved have large oscillator strengths. Obsevational reasons. ~hjmo/astro/lecturepdf.

QSO metal-line absorption systems are reviewed in the context of galaxy formation and evolution. Attention is focused on the high column density “damped Lyα” absorption systems, which dominate the cosmological mass density of neutral gas in the universe and hence trace the bulk of material available for star formation to high redshifts Recent evidence of evolution of the gaseous T1 - Observations of nickel, chromium, and zinc in QSO absorption-line systems.
