Global Inflow and Outflow Solutions (GIOS) around a Black Hole

Twenty five years have passed by since models of accretions and jets have separately emerged. Today, it is understood that these two objects are related to each other in a fundamental way. In a binary system, matter from an accretion disk enters into a black hole. A part of it is bounced back because of the centrifugal barrier, radiation pressure or magnetohydrodynamic effects, to form jets and bipolar outflows which carry away excess angular momentum. In the case of AGNs containing black holes, accretion disks form out of stellar winds and similar processes as above form cosmic radio jets. We present a general review of the study of the accretion disks and outflows in a coherent manner, especially emphasizing global inflow-outflow solutions (GIOS). We also present a few observational consequences of wind production from the accretion disks on spectral properties of the accretion disks.
