# Features

The DeepSZSim package uses the DeepCMBSim package to simulate large-scale modes of the CMB. These modes are combined with the SZ effect to generate realistic simulations of cluster images.

The full package workflow is demonstrated in Figure \autoref{fig:workflow}.

## DeepCMBSim


## DeepCMBSim Modul

The `DeepCMBsim` package combines physical processes and sources of noise in a software framework that enables fast and realistic simulation of the CMB in which key cosmological parameters can be varied. DeepCMBSim simulates correlations of temperatures and polarization signals from the CMB, including large-scale gravitational lensing and BB polarization caused by non-zero tensor-to-scalar ratios.

The package workflow is demonstrated in Figure \autoref{fig:workflow}.
We present examples of the primary outputs from `DeepCMBSim` in Figure \autoref{fig:cmb}.


We provide an example notebook in `notebooks/simcmb_example.ipynb` which demonstrates the software functionality.

## DeepSZSim
## SZ Cluster Simulation

`DeepSZsim` includes code for producing fast simulations of the thermal Sunyaev-Zeldovich effect for galaxy halos of varying mass and redshift, based on average thermal pressure profile fits from Battaglia et al. 2012 `[@Battaglia:2012]`. The output is an array of simulated submaps of the tSZ effect associated with galaxy halos, which can include simulated CMB, instrument beam convolution, and/or white noise.

The output is an array of simulated submaps of the tSZ effect associated with galaxy halos, which can include simulated CMB, instrument beam convolution, and/or white noise.

The user provides inputs to generate an array of redshift and mass ($M_200$) for dark matter halos, the desired pixel and submap size for the output submaps, and inputs such as experiment properties (observation frequency, noise level, beam size) and a cosmological model. These inputs are easily customizable, or the user can run defaults based on the Atacama Cosmology Telescope `[@ACT:2021]` and Planck cosmology `[@Planck:2019]`. Cosmology computations depend on `colossus` `[@Colossus:2018]` and `astropy` `[@Astropy:2013]`.

From these inputs, pressure profiles [cite], Compton-y profiles [cite], and tSZ signal maps are generated for the dark matter halo array. Simulated CMB primary anisotropy maps can be generated through a dependency on `DeepCMBSim`. Final simulated submaps can include instrument beam convolution and white noise `[@actnotebooks:2015]`. Plotting functions for the simulations and an aperture photometry filter are included as tools. The submap handling functions rely on `pixell` `[@pixell:2024]`.

We present examples of the primary outputs from `DeepCMBSim` and `DeepSZSim` in, Figure \autoref{fig:cmb} and Figure \autoref{fig:sz}, respectively.
