Suzaku search for emission from missing baryons
Nearby of a massive cluster Akamatsu+2011 Middle of two massive clusters Mitsuishi+2011 No missing baryon was found.

The referee might need courage to accept the observation of “blank fields” $ 30 billion (total)/ 5 years x 80 ksec = $ 0.15 million for “blank field” ! Thank you very much for accepting
Massive Cluster A2142 Merging Galaxy Group Suzaku J1552+2739 9 keV 1.6 keV Suzaku J1552+2739 is not WHIM ( < 1 keV ) But was Missing Baryon
In 2011 (Suzaku AO-6 period)
How to select the targets ?
