Research Abstract |
Our bodies and stars consist of baryon(ordinary matter). Recent researches such as anisotropies of cosmic microwave background radiation and type Ia supernovae have revealed how much baryon there are in the universe, but most of it has not been observed yet. We studied the properties of this missing baryon being referred to as dark baryon with numerical simulations and analytic models. We also studied some special astronomical satellites to observe dark baryon.
