The Supersonic Project: Lighting up the faint end of the JWST UV luminosity function

The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe when the supersonic relative motions between dark matter and baryonic overdensities modulate structure formation (\(z>\sim 10\)). We study low-mass galaxy formation including this "stream velocit...

Zusammenfassung:The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe when the supersonic relative motions between dark matter and baryonic overdensities modulate structure formation (\(z>\sim 10\)). We study low-mass galaxy formation including this "stream velocity" using high resolution AREPO hydrodynamics simulations, and present theoretical predictions of the UV luminosity function (UVLF) and galaxy stellar mass function (GSMF) down to extremely faint and low mass galaxies (\(M_{UV}>\sim-15\), \(10^4M_\odot
