Internal Structure of high-z Galaxies with NGST
نویسنده
چکیده
Models of galaxy evolution are used to determine the redshift interval, sampled in the 1–5μm wavelength window, over which metallicity, internal extinction, and internal kinematics of high redshift galaxies can be derived from emission and absorption line measurements. A multi-aperture multi-object spectrograph is the optimal solution for such kind of study, since current data such as the HDF images suggest that the Universe is only sparsely populated with luminous objects at the spectroscopic magnitude limit of NGST.

Emission-line Diagnostics of Galaxy Evolution with Ngst
As a byproduct of its search for the first star forming galaxies, NGST will obtain high-quality spectra for thousands of galaxies in the redshift range z = 0 − 6 and beyond. Most of the galaxies will possess strong emission-line spectra, and these spectra will provide a wealth of quantititative information on their star formation rates, reddening, metal abundances, internal kinematics, and nucl...
متن کاملMeasuring the mass of high-z galaxies with NGST
We discuss dynamical mass measurements of high-z galaxies with the Next Generation Space Telescope (NGST). In particular, we review some of the observational limits with the current instrument/telescope generation, we discuss the redshift limits and caveats for absorption and emission lines studies with NGST, and the existence of suitable targets at high redshift. We also briefly summarize stre...
متن کاملHigh-Redshift Galaxies: Their Predicted Size and Surface Brightness Distributions and Their Gravitational Lensing Probability
Direct observations of the first generation of luminous objects will likely become feasible over the next decade. The advent of the Next Generation Space Telescope (NGST ) will allow imaging of numerous galaxies and mini-quasars at redshifts z ∼> 5. We apply semi-analytic models of structure formation to estimate the rate of multiple imaging of these sources by intervening gravitational lenses....
متن کاملGravitational Lensing of High Redshift Sources
The combination of deep exposures and high resolution offered by telescopes in space allows the detection of lensing over a wide range of source redshifts and lens masses. As an example, we model a lens candidate found in the southern Hubble Deep Field. The system consists of a source galaxy lensed into an arc, 0. 9 from an elliptical galaxy. The photometric redshift of 0.6 for the lens galaxy ...
متن کاملDust - penetrated morphology in the high - redshift universe : Clues from NGC 922
Results from the Hubble Deep Field (HDF) North and South show a large percentage of high-redshift galaxies whose appearance falls outside traditional classification systems. The nature of these objects is poorly understood, but sub-mm observations indicate that at least some of these systems are heavily obscured (Sanders 2000). This raises the intriguing possibility that a physically meaningful...
