“…Our assumption linking the amplitude of the SZ effect to the bolometric luminosities of quasars indicates a lower signal for the thermal SZ effect around lower redshift quasars. This is contrary to what might be expected when considering the detection of fossil feedback energy due to the long cooling times in quasar dark matter halos (Planck Collaboration et al 2013;Greco et al 2015;Spacek et al 2016Spacek et al , 2017Spacek et al , 2018Tanimura et al 2019;Pandey et al 2019). However, if we consider that quasars are a phase in galaxies' evolution (Hopkins et al 2005b), then the quasars that we observe at lower redshifts may not have been quasars at high redshift.…”

“…This has been done for massive elliptical systems (with halo mass ∼ 10 14 M ) associated with luminous red galaxies (Hand et al 2011). Others observed systems with halo mass ∼ 10 13 M that have characteristic total energies of 7 × 10 61 ergs in the circumgalactic medium (Planck Collaboration et al 2013;Greco et al 2015;Spacek et al 2016Spacek et al , 2017Spacek et al , 2018Tanimura et al 2019;Pandey et al 2019). These latter studies aim to detect fossil energy from past AGN activity -coincidentally of the same order as the cluster feedback energy scale quoted above.…”

In this paper we probe the hot, post-shock gas component of quasar-driven winds through the thermal Sunyaev-Zel'dovich (tSZ) effect. Combining datasets from the Atacama Cosmology Telescope, the Herschel Space Observatory, and the Very Large Array, we measure average spectral energy distributions (SEDs) of 109,829 opticallyselected, radio quiet quasars from 1.4 GHz to 3000 GHz in six redshift bins between 0.3 < z < 3.5. We model the emission components in the radio and far-infrared, plus a spectral distortion from the tSZ effect. At z > 1.91, we measure the tSZ effect at 3.8σ significance with an amplitude corresponding to a total thermal energy of 3.1 × 10 60 ergs. If this energy is due to virialized gas, then our measurement implies quasar host halo masses are ∼ 6 × 10 12 h −1 M . Alternatively, if the host dark matter halo masses are ∼ 2 × 10 12 h −1 M as some measurements suggest, then we measure a >90 per cent excess in the thermal energy over that expected due to virialization. If the measured SZ effect is primarily due to hot bubbles from quasar-driven winds, we find that (5 +1.2 −1.3 ) per cent of the quasar bolometric luminosity couples to the intergalactic medium over a fiducial quasar lifetime of 100 Myr. An additional source of tSZ may be correlated structure, and further work is required to separate the contributions. At z ≤ 1.91, we detect emission at 95 and 148 GHz that is in excess of thermal dust and optically thin synchrotron emission. We investigate potential sources of this excess emission, finding that CO line emission and an additional optically thick synchrotron component are the most viable candidates.

“…However, the AGN feedback-induced tSZ is expected to be too feeble to be detected at the single source level, therefore one must resort to statistical techniques such as cross-correlation and stacking. The first tentative detection of tSZ due to AGN feedback effect was reported by Chatterjee et al (2009), while subsequent works by Ruan et al (2015); Crichton et al (2016); Verdier et al (2016); Spacek et al (2016Spacek et al ( , 2017; Soergel et al (2017) found evidence of this effect at different significance levels. However, there is no general consensus as the inferred thermal energies differ substantially among the various studies.…”

We present the mean spectral energy distribution (SED) of a sample of optically selected quasars (QSOs) at redshifts of 1 ≤ z ≤ 5. To derive it, we exploit photometric information from SDSS, UKIDSS, and WISE surveys in combination with a stacking analysis of Herschel, AKARI, and Planck maps at the location of the QSOs. The near-UV and optical parts of the reconstructed mean rest-frame SED are similar to those found in other studies. However, the SED shows an excess at 1-2 µm (when compared to the aforementioned SEDs normalized in the near-UV) and a prominent bump around 4-6 µm, followed by a decrease out to ∼ 20 µm and a subsequent far-IR bump. From the fitted SEDs we estimate the average active galactic nuclei (AGN) luminosity L AGN and star formation rate (SFR) as function of cosmic time, finding typical L AGN ∼ 10 46 − 10 47 erg/s and SFR ∼ 50 − 1000 M /yr. We develop mid-IR based criteria to split the QSO sample, finding that these allow us to move along the average relationship in the SFR vs. L AGN diagram toward increasing AGN luminosities. When interpreted in the context of the in-situ coevolution scenario presented by Lapi et al. (2014), our results suggest that the detection in the far-IR band is an effective criterion to select objects where the star formation is on the verge of being affected by energy/momentum feedback from the central AGN.

Two-halo term in stacked thermal Sunyaev-Zel’dovich measurements: Implications for self-similarity

et al. 2018

The relation between the mass and integrated electron pressure of galaxy group and cluster halos can be probed by stacking maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. Perhaps surprisingly, recent observational results have indicated that the scaling relation between integrated pressure and mass follows the prediction of simple, self-similar models down to halo masses as low as 10 12.5 M . Hydrodynamical simulations that incorporate energetic feedback processes suggest that gas should be depleted from such low-mass halos, thus decreasing their tSZ signal relative to selfsimilar predictions. Here, we build on the modeling of Vikram, Lidz, and Jain (2017) to evaluate the bias in the interpretation of stacked tSZ measurements due to the signal from correlated halos (the "two-halo" term), which has generally been neglected in the literature. We fit theoretical models to a measurement of the tSZ -galaxy group cross-correlation function, accounting explicitly for the one-and two-halo contributions. We find moderate evidence of a deviation from self-similarity in the pressure -mass relation, even after marginalizing over conservative miscentering effects. We explore pressure -mass models with a break at 10 14 M , as well as other variants. We discuss and test for sources of uncertainty in our analysis, in particular a possible bias in the halo mass estimates and the coarse resolution of the Planck beam. We compare our findings with earlier analyses by exploring the extent to which halo isolation criteria can reduce the two-halo contribution. Finally, we show that ongoing third-generation CMB experiments will explicitly resolve the one-halo term in low-mass groups; our methodology can be applied to these upcoming data sets to obtain a clear answer to the question of self-similarity and an improved understanding of hot gas in low-mass halos.
