- This is the tSZ map, in units of Compton-y (dimensionless), with the rescaling factor applied to bring the amplitude of the power spectrum into reasonable agreement with the Planck 2013 y-map tSZ power spectrum. Note that the user must rescale this map to each frequency by multiplying by the tSZ spectral function and T_CMB=2.726e6 uK.

MillimeterDL simulations are full-sky millimeter-wave Deep Learning simulations that include lensed CMB maps and correlated foreground components. By using Generative Adversarial Networks, they generated full-sky non-Gaussian extragalactic foregrounds, non-Gaussian kappa maps, and the corresponding lensed CMB maps. The mmDL simulations are trained using the cosmology and extragalactic model described in Sehgal et al. (2010). They use WMAP-5 cosmological parameters.

The Magneticum simulations are a set of state-of-the-art (Dolag et al., 2016), cosmological hydrodynamical simulations of different cosmological volumes with different resolutions performed with an improved version of GADGET3 (Beck et al. 2016). From the Magneticum simulation, they approximated the lightcone of 35x35 deg by a series of redshift slices, and all gas particles contributed to the SZ simulated map.

The Magneticum simulations are a set of state-of-the-art (Dolag et al., 2016), cosmological hydrodynamical simulations of different cosmological volumes. By using redshift slices of small boxes (Box1 up z = 0.17) and large boxes (Box0 up to z=0.5) and replicating it each spatial direction, they constructed full sky maps extended up to z = 1.2. They also included Local universe contribution, by combining the Magneticum full sky maps with the contribution obtained from a constrained, local universe simulation (see Dolag et al. 2005; Dolag et al. 2016) covering the redshift range of 0 < z < 0.027.

Full sky tSZ- and kSZ maps are produced from the new pipeline The Websky Extragalactic CMB Simulations (semi-analytical approach). The first part of the pipeline generates a random cosmological realization in the form of a dark matter halo catalog and matter displacement field, modeled with ellipsoidal collapse dynamics. In the second part, the cosmological realization is converted into a set of intensity maps over the range 10 - 10^3 GHz using models based on existing observations and hydrodynamical simulations.
