“…Our results, shown in Table 3 and Fig. 9, agree well with previous measurements of the same quantity (Vikram et al 2017;Pandey et al 2019), as well as with shock-heating models (Battaglia et al 2012b). This result is also the most precise measurement of the large-scale correlation between δg and y to date.…”

“…This quantity can be interpreted both as the relation between large-scale matter and pressure fluctuations and as the halo-bias-weighted thermal energy density of all haloes at a given redshift (Battaglia et al 2017). It has been measured at low redshifts by Vikram et al (2017) making use of galaxy groups, and at higher redshifts by the Dark Energy Science Collaboration (Pandey et al 2019). The redshift range 0.1 z 0.4, containing a large fraction of the tSZ sources detected by Planck (Planck Collaboration et al 2016b), has been so far fairly unconstrained tomographically through this type of measurements.…”

“…Han et al 2019;Abbott et al 2019;Peacock & Bilicki 2018), as well as to calibrate the measurement of galaxy shapes in cosmic shear analyses (Abbott et al 2019). The tSZ effect has been used in cross-correlation with galaxy clustering and weak lensing data to determine the physical properties of the diffuse gas, as well as to potentially improve constraints on the amplitude of matter fluctuations (Van Waerbeke et al 2014;Hill & Spergel 2014;Ma et al 2015;Hojjati et al 2017;Atrio-Barandela & Mücket 2017;Makiya et al 2018;de Graaff et al 2019;Tanimura et al 2019a,b;Pandey et al 2019;Makiya et al 2019). The kSZ has been used in cross-correlation with galaxy clustering to constrain the growth of structure and the gas density profile around haloes (Schaan et al 2016;Planck Collaboration et al 2016a;Hill et al 2016;Soergel et al 2016;De Bernardis et al 2017).…”

We cross-correlate maps of the thermal Sunyaev-Zeldovich (tSZ) Compton-y parameter published by Planck with the projected distribution of galaxies in a set of lowredshift tomographic bins. We use the nearly full-sky 2MASS Photometric Redshift and WISE × SuperCOSMOS public catalogues, covering the redshift range z 0.4. Our measurements allow us to place constraints on the redshift dependence of the mass-observable relation for tSZ cluster count analyses in terms of the so-called 'hydrostatic mass bias' parameter 1 − b H . These results can also be interpreted as measurements of the bias-weighted average gas pressure bP e as a function of redshift, a quantity that can be related to the thermodynamics of gas inside haloes and used to constrain energy injection processes. We measure 1 − b H with ∼ 13% precision in 6 equispaced redshift bins, and find no evidence for a redshift-dependent mass bias parameter, in agreement with previous analyses. Our mean value of 1−b H = 0.59±0.03 is also in good agreement with the one estimated by the joint analysis of Planck cluster counts and CMB anisotropies. Our measurements of bP e , at the level of ∼ 10% in each bin, are the most stringent constraints on the redshift dependence of this parameter to date, and agree well both with previous measurements and with theoretical expectations from shock-heating models.

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.

LiteBIRD the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and fundamental physics. The Japan Aerospace Exploration Agency (JAXA) selected LiteBIRD in May 2019 as a strategic large-class (L-class) mission, with an expected launch in the late 2020s using JAXA’s H3 rocket. LiteBIRD is planned to orbit the Sun-Earth Lagrangian point L2, where it will map the cosmic microwave background (CMB) polarization over the entire sky for three years, with three telescopes in 15 frequency bands between 34 and 448 GHz, to achieve an unprecedented total sensitivity of 2.2 μK-arcmin, with a typical angular resolution of 0.5○ at 100 GHz. The primary scientific objective of LiteBIRD is to search for the signal from cosmic inflation, either making a discovery or ruling out well-motivated inflationary models. The measurements of LiteBIRD will also provide us with insight into the quantum nature of gravity and other new physics beyond the standard models of particle physics and cosmology. We provide an overview of the LiteBIRD project, including scientific objectives, mission and system requirements, operation concept, spacecraft and payload module design, expected scientific outcomes, potential design extensions and synergies with other projects. Subject Index LiteBIRD cosmic inflation, cosmic microwave background, B-mode polarization, primordial gravitational waves, quantum gravity, space telescope
