Abstract
We present the first results from our pilot 500 ks Chandra Low Energy
Transmission Grating Large Program observation of the soft X-ray
brightest source in the z >~ 0.4 sky, the blazar 1ES 1553+113, aimed
to secure the first uncontroversial detections of the missing baryons in
the X-rays. We identify a total of 11 possible absorption lines, with
single-line statistical significances between 2.2σ and 4.1σ.
Six of these lines are detected at high single-line statistical
significance (3.6
