About 50% of the Universe's baryons are missing. They are thought to be hiding in an intergalactic network of extremely tenuous million degree plasma: the Warm-Hot Intergalactic Medium (WHIM).
The only way to detect the missing baryons and start studying their continuous interplay and feedback with Large Scale Structures with current instrumentation, is to expose the Chandra and XMM gratings for several Ms, against the best WHIM sightline possible.
Deeper and systematic studies must await for larger throuput, higher spectral resolution strumentation.
Two years ago, we identified and selected the best WHIM sightline in the Universe, against the FUV and X-Ray bright blazar 1ES 1553+113, and last year we were awarded the first half Ms observation of this target. At the time of writing, the first 300 ks of observation have just been performed, and a preliminary analysis of the data shows the presence of several absorption features.
Here we present our findings from the full set of data from this half Ms Chandra Large Program.
