Kinematic Modeling of Distant Galaxies

The Most Distant Galaxies

I review selected current observations of distant galaxies and our interpretation of the fragile (and occasionally contradictory) data. Galaxies at the “contemporary limit” of technology and redshift (z ∼ 6) are difficult to locate in the first place. Moreover, the large redshift may push some critical confirming and/or interpretative analysis toward unfamiliar IR wavelengths. I will concentrat...

Search Techniques for Distant Galaxies

How and when do galaxies form? Studies of the microwave background radiation reveal that the Universe is spectacularly homogenous at redshift z ≈ 1000. Observations of the local Universe reveal that by z = 0 much of the luminous matter has condensed into mature, gravitationally-bound structures. One of the primary challenges to astronomers today is to achieve a robust understanding of this proc...

The Ism in Distant Galaxies

The interstellar medium (ISM) is a key ingredient in galaxy formation and evolution as it provides the molecular gas reservoir which fuels star formation and supermassive black hole accretion. Yet the ISM is one of the least studied aspects of distant galaxies. Molecular and atomic transitions at (sub)millimetre wavelengths hold great promise in measuring macroscopic properties (e.g. masses, mo...

Interacting Nuclei in Distant Galaxies

The interaction of galaxies not only occurs in galactic scales, but also may be linked to the binary cores in active galactic galaxies. The presence of a binary in the center of galaxies was suggested by Begelman, Blandford and Rees (1980). Gaskell (1983) suggests that supermassive binaries may account for the observed structure of emission line profiles such as double peaks displaced by a sign...
