Abstract : The thermal Sunyaev-Zeldovich (SZ) effect is the spectral distortion of the cosmic microwave background (CMB) radiation by energetic electrons. The SZ effect can be used as a direct potential probe of energetic outflows (known as feedback) from quasars which are responsible for heating the intergalactic medium. In this work, we use the GADGET-3 simulations which include dark matter and gas dynamics, radiative cooling, star formation, black hole growth, and energy-driven feedback (MassiveBlack-II) to compute the SZ effect arising from quasar feedback. From these theoretical simulations, we perform mock observations of the new generation Very Large Array (ngVLA) and the Atacama Large Millimeter Array (ALMA) to characterize the feasibility of direct direction of the quasar-SZ signal. We also compare the simulated ALMA maps of SZ distortion with that of the mock Chandra X-ray maps around the same quasars to perform a joint analysis of these systems. Our work for the first time provides a machinery to perform direct joint X-ray-SZ observations of quasars and extract the feedback energy from them.
