Hst Proposal Id #10687 Quasar Absorption Lines And Igm

Scientific paper

We propose to develop a new, more physical method to describe QSO absorption-line statistics and their relationship to galaxies visible in the sky. We propose to apply this method to the Hubble Ultra Deep Field {UDF}. Using results on QSO absorption-line statistics and direct observations of galaxies that give rise to QSO absorption lines, we will develop a prescription for the gaseous cross-sections surrounding galaxies. We will apply this prescription to the UDF galaxies, simulate sightlines through the UDF galaxies, and infer QSO absorption-line statistics which are expected given the observed UDF galaxy properties. The prescription will be iterated until consistency with observed QSO absorption-line statistics is obtained. We believe that such a study can help bridge the gap between traditional QSO absorption-line and galaxy imaging surveys.
