Title: Exploring the Dusty Star-Forming Galaxy population: a mock redshift survey for deep mm-wavelength observations

Abstract: This work introduces a new cosmologically motivated mock redshift survey of the Dusty Star-Forming Galaxy (DSFG) population. Some of these galaxies exhibit extreme properties, such as star formation rates of hundreds of M⊙/yr, and contribute significantly to the cosmic star formation rate. This highlights the importance of studying the DSFGs at infrared and millimeter wavelengths to obtain a complete view of the star formation history in the Universe. Our publicly available mock survey is based on the Bolshoi-Planck dark-matter halo simulation, covering an area of 5.3 sq. deg. from z =0-7 with a stellar-mass lower limit of 10^8.75 M⊙. It includes gravitational lensing effects and closely reproduces the DSFG measurements. We characterize the future extra-galactic ultra-deep legacy survey (UDS) that will be conducted by the TolTEC camera installed on the 50m Large Millimeter Telescope, mapping a total of 0.8 sq. deg. of the sky, including UDS, GOODS-S and COSMOS fields. Additionally, we investigate the impact of clustering and lensing on the flux-boosting effect due to blending of sources within a single telescope beam. Recently, we developed a larger 100 sq.degree mock redshift survey, with a stellar mass lower limit of 10^9.5 M⊙, which allows us to explore the clustering properties of the DSFGs within the Large Scale Structure and the physical properties of those galaxies that pinpoint overdense regions at high-z. These mock redshift surveys represent a valuable tool for the characterization and interpretation of results derived from near-future large-area mm-wavelength surveys (particularly those to be conducted with TolTEC), which will be complementary to the higher angular resolution interferometric observations with ALMA and the new generation of space- and ground-based facilities.
