The Evolution of Galaxies on Cosmological Timescales
نویسنده
چکیده
The 9.2 m Hobby-Eberly Telescope (HET) is beginning science operations. It provides a unique approach to very large telescope development, with high performance at modest cost. The HET is already being cloned in the Southern hemisphere and may be the basis for the development of signi cantly larger telescopes for the new Millennium. We describe the current performance of the HET and of the newly commissioned Marcario Low Resolution Spectrograph (LRS), for which the author is the PI. Projects on high redshift clustering are already underway, and early results are presented here. In particular, the TexasOxford high redshift cluster survey has already yielded several clusters with LRS redshifts as high as z=0.6.

Chemically Consistent Evolution of Galaxies on Cosmological Timescales and the Dla Galaxy Population
We describe the evolution of galaxies in a chemically consistent way accounting for the increasing initial metallicity of successive generations of stars. The enrichment of various types of model galaxies is compared with Damped Lyα (= DLA) abundances over the redshift range from z ∼ 0 through z > 4.4. We discuss properties and composition of the galaxy population giving rise to DLA absorption....
متن کاملPulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I
We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...
متن کاملChemically Consistent Evolutionary Synthesis
To account for the range of stellar metallicities in local galaxies and for the increasing importance of low metallicities at higher redshift we present chemically consistent models for the spectral and chemical evolution of galaxies over cosmological timescales. We discuss advantages, limitations and future prospects of our approach.
متن کاملThe Evolution of X-ray Binaries on Cosmological Timescales
The observation of X-ray sources has been revolutionized by spaced-based observatories such as Chandra and XMM-Newton, which have already provided vast amounts of valuable data on galaxies in the X-ray bands. These combined with observations done in other wavelengths have provided a large amount of information regarding the global properties of distant galaxies and their effect on the overall p...
متن کاملWhy Is the Cmb Fluctuation Level 10 − 5 ?
We explore the qualitative changes that would occur if the amplitude Q ∼ 10 of cosmological density fluctuations were different. If Q ∼< 10 , the cosmological objects that form would have so low virial temperatures that they may be unable to cool and form stars, and would be so loosely bound that even if they could produce a supernova explosion, they might be unable to retain the heavy elements...
متن کاملProbing the Chemical Abundances in Distant Galaxies with 10-m Class Telescopes
The determination of chemical abundances in star-forming galaxies and the study of their evolution on cosmological timescales are powerful tools for understanding galaxy formation and evolution. This contribution presents the latest results in this domain. We show that detailed studies of chemical abundances in UV-selected, Hii and starburst nucleus galaxies, together with the development of ne...
