Impacts of photon bending on observational aspects of Two Component Advective Flow

TL;DR

This paper investigates how photon bending in curved spacetime affects observational features of the Two Component Advective Flow model around black holes, analyzing parameters like redshift, flux, and photon arrival times.

Contribution

It provides a detailed analysis of photon trajectory effects on observational signatures in the TCAF model without restricting photon motion to a plane.

Findings

Photon bending significantly influences redshift and flux measurements.

Photon arrival times are affected by spacetime curvature around black holes.

Temperature profiles are altered due to photon trajectory deviations.

Abstract

Nature of photon trajectories in a curved spacetime around black holes are studied without constraining their motion to any plane. Impacts of photon bending are separately scrutinized for Keplerian and CENBOL components of Two Component Advective Flow (TCAF) model. Parameters like Red shift, Bolometric Flux, temperature profile and time of arrival of photons are also computed.
