S82X

This repository contains some of the n-dim array used in Peca et al. 2023 (see full paper for details):

• The Corrections folder contains the corrections to derive intrinsic AGN distributions.
• The XLF folder contains the derived X-ray luminosity function. To use Peca23_XLF.py you need to also download Peca23_XLF.npy in the same folder. See below how to use the XLF and obtain the number density of AGN [Mpc-3] for a given luminosity and redshift bins or single values.

These files are free to use, but if you use them, please cite our paper at this link.

To use the XLF:

This script (Peca23_XLF.py) computes and plots the X-ray Luminosity Function (XLF) based on a provided dataset. It can evaluate the XLF at specific points or integrate over specified luminosity and redshift ranges.

Evaluating XLF at a specific luminosity and redshift

To evaluate the XLF at a specific luminosity (Lx) and redshift (z):

python Peca23_XLF.py <log Lx> <z>

The result will be printed in the terminal.

Evaluating XLF in luminosity and redshift bins

To integrate the XLF over a range of luminosities (Lx_min to Lx_max) and redshifts (z_min to z_max):

python Peca23_XLF.py <log Lx_min> <log Lx_max> <z_min> <z_max>

The result will be printed in the terminal.

Evaluating XLF in luminosity and fixed redshift

To integrate the XLF over a range of luminosities (Lx_min to Lx_max) and fixed redshift:

python Peca23_XLF.py <log Lx_min> <log Lx_max> <z>

NOTE: The script will print a warning if the provided values are outside the predefined ranges (log Lx [42-47], z [0,4]) derived in Peca et al. 2023. For larger ranges, the code will compute a linear extrapolation, so use it with caution.

NOTE: A very small number of C-thick AGN were discovered in Peca+23, therefore this XLF has to be considered reliable up to $\log N_H \sim 24\ \ cm^2$.

Plotting control

The script will automatically print the 3D XLF with the requested volume density in red. To disallow the plotting option just add --plot=False
