We present a statistical analysis of the millimetre-wavelength properties of 1.4 GHz-selected sources and a detection of the Sunyaev–Zel'dovich (SZ) effect associated with the haloes that host them. We stack data at 148, 218 and 277 GHz from the Atacama Cosmology Telescope at the positions of a large sample of radio AGN selected at 1.4 GHz. The thermal SZ effect associated with the haloes that host the AGN is detected at the 5σ level through its spectral signature, representing a statistical…

Quantifying the thermal Sunyaev–Zel’dovich effect and excess millimetre emission in quasar environments
In this paper, we probe the hot, post-shock gas component of quasar-driven winds through the thermal Sunyaev–Zel’dovich (tSZ) effect. Combining data sets from the Atacama Cosmology Telescope, the
Evidence for the thermal Sunyaev-Zel'dovich effect associated with quasar feedback
Using a radio-quiet subsample of the Sloan Digital Sky Survey spectroscopic quasar catalogue, spanning redshifts 0.5-3.5, we derive the mean millimetre and far-infrared quasar spectral energy

Quasar host environments: The view from Planck
We measure the far-infrared emission of the general quasar (QSO) population using Planck observations of the Baryon Oscillation Spectroscopic Survey QSO sample. By applying multi-component matched
We present a multi-wavelength analysis of eleven Sunyaev Zel’dovich eect (SZE)-selected galaxy clusters (ten with new data) from the Atacama Cosmology Telescope (ACT) southern survey. We have
Detection of Quasar Feedback from the Thermal Sunyaev-Zel’dovich Effect in Planck
Poorly understood feedback processes associated with highly luminous black hole accretion in quasars may dramatically affect the properties of their host galaxies. We search for the effect of quasar

We present constraints on cosmological and astrophysical parameters from high-resolution microwave background maps at 148 GHz and 218 GHz made by the Atacama Cosmology Telescope (ACT) in three
SZ effects in the Magneticum Pathfinder Simulation: Comparison with the Planck, SPT, and ACT results
We calculate the one-point probability density distribution functions (PDF) and the power spectra of the thermal and kinetic Sunyaev-Zeldovich (tSZ and kSZ) effects and the mean Compton Y parameter

Simulations of the Sunyaev–Zel'dovich effect from quasars
Quasar feedback has most likely a substantial but only partially understood impact on the formation of structure in the universe. A potential direct probe of this feedback mechanism is the
