Flaring up of the Compact Cloud G2 during the Close Encounter with Sgr A*
Takayuki R. Saitoh, Junichiro Makino, Yoshiharu Asaki +8
A compact gas cloud G2 is predicted to reach the pericenter of its orbit around the super massive black hole (SMBH) of our galaxy, Sagittarius A* (Sgr A*). This event will give us…
