100 deg$^2$ Mock Galaxy Cone for HI Surveys with the Early SKA

TL;DR

This paper presents a comprehensive, easy-to-use mock galaxy catalog covering 100 square degrees with detailed HI properties, designed to aid future HI surveys with the SKA, including flux limits and completeness details.

Contribution

The authors provide a publicly available, detailed mock galaxy catalog with HI and other properties, tailored for SKA HI survey planning and analysis.

Findings

Catalog covers 10x10 degrees and redshift 0-1.2.

Includes galaxies with 21cm flux down to 1uJy, complete above 10^8 solar masses.

Multiple realizations and flux-limited subsets are available for download.

Abstract

We distribute an easy-to-use mock catalog of galaxies with detailed neutral atomic hydrogen (HI) and auxiliary molecular and optical properties. The catalog covers a field of 10-by-10 degrees and a redshift range of z=0-1.2. It contains galaxies with 21cm peak flux densities down to 1uJy and is, within this flux limit, complete for HI masses above 10^8 solar masses. Five random realisations of the catalog in ASCII format (~4GB/file) and subtables with HI flux limits of 10u Jy (~500MB/file) and 100uJy$ (~30MB/file) can be downloaded at http://ict.icrar.org/store/staff/do/s3sax.
