Abstract:
We present a detailed analysis of the intergalactic metal-line
absorption systems in the archival HST STIS and FUSE ultraviolet
spectra of the low-redshift quasar PKS 1302-102 (zQSO=0.2784). We
supplement the archive data with CLOUDY ionization models and a survey
of galaxies in the quasar field.
Description:
PKS 1302-102 was observed for a total of 22ks by HST STIS in 2001
August (Program 8306; PI: M. Lemoine).
PKS 1302-102 was observed for a total of 149ks with FUSE between 2000
May and 2001 January (Program P108; PI: K. Sembach).
