Confirming the Detection of an Intergalactic X-Ray Absorber toward PKS 2155-304

Confirming the Detection of an Intergalactic X-Ray Absorber toward PKS 2155-304

We present new observations of PKS 2155-304 with the Chandra Low Energy Transmission Grating (LETG), using the Advanced CCD Imaging Spectrometer (ACIS). We confirm the detection of an absorption line plausibly identified as O VIII Lyα from a warm-hot intergalactic medium associated with a small grou...
