| Research Abstract |
We studied so-called missing baryon problem, which is one of the remaining questions in modern cosmology. We took two approaches : observational study and development of a new cryogenic detector. We have developed signal multiplexing technique for the cryogenic detector microcalorimeters and have extended the bandwidth of the detector by a order of magnitude. By performing numerical simulations, we confirmed the sensitivity of the detector and the simulation is consistent with the upper limit of the surface brightness we obtained from observations.
