Observable features of charged Kiselev black hole with non-commutative geometry under various accretion flow

Abstract The light passing near the black hole (BH) is deflected due to gravitational effect, producing BH shadow, a dark inner region that often surrounded by bright ring, whose optical appearance comes directly from BH’s mass and its angular momentum. We mainly study shadow observable features of non-commutative (NC) charged Kiselev BH, various profiles accretions. To obtain profile, we choose specific values model parameters concluded variations each parameter vary trajectories size BH. For thin disk accretion, which includes direct lensing photon rings emissions, analyze profile contains interior ring. However, their details depends upon generally, emission plays significant role in total observed luminosity, while ring has small contribution makes negligible contribution, as usual, latter can be ignored safely. Moreover, also consider static infalling accretion matters found location sphere almost same for both cases. intensity darker case Doppler effect motion compared one.
