Gen-X view of the Hubble Deep Field

• Galaxies at z=1-3 show increased star formation rate and X-ray luminosity
• For the Hubble Deep Field, Chandra detects only 17 galaxies in 2 Ms
• Gen-X would detect most of the 3000 galaxies seen by HST including ~800 galaxies at z~3 having >=400 counts in 1 Ms
• Gen-X will spatially separate XRB from the nuclear BH and spectrally separate hard XRB emission from hot gas to reveal the true SFR

Galaxy Evolution and Populations

• Gen-X sufficiently resolves the dominant X-ray binaries to allow X-ray Population Synthesis and study of galaxy evolution
• Study chemical evolution with SNR enrichment of ISM to 10 Mpc
• High resolution spectra of Fe, Si and O drives the requirement for energy resolving power ~ 10³
