Intergalactic
Medium Project
Cosmological simulations and quasar absorption line studies reveal an
intergalactic medium, a "Cosmic Web", that has a profound effect on the
formation and evolution of galaxies, and shows the influence of galactic
feedback.
The goals of the Intergalactic Medium Project are to develop new
instrumentation and observational techniques to detect IGM emission from the
ground and in space and use it to map and characterize the Cosmic Web and its
relationship to galaxies and to the underlying distribution of Dark Matter.
Goals
 | Mapping the IGM in space and time |
| Understanding physical conditions in the IGM |
| Understanding the physical processes governing in the formation and
evolution of galaxies embedded in the IGM |
| Using IGM to trace dark matter
and large scale structure |
| Using
IGM emission as a cosmological tool |
Projects

FIREBALL -- Faint Intergalactic Redshifted Emission BALLoon
A balloon-borne high-resolution UV integral field spectrograph designed to
detect and map faint emission from the redshifted IGM in lines of HI 1216,
CIV 1550, and OVI 1033 Angstroms. This project is a collaboration of
Caltech, Columbia University, and CNES. |

Cosmic
Web Imager An
high-resolution UV
integral field spectrograph to be placed on the Palomar 200 inch telescope,
designed to detect and map faint emission from the redshifted IGM in lines
of HI 1216, CIV 1550, and OVI 1033 Angstroms, over a redshift range of
2<z<7. |
