NED Abstract

Copyright by Royal Astronomical Society. 2014MNRAS.437.1698M X-ray emission from star-forming galaxies - III. Calibration of the L_X_-SFR relation up to redshift z ~ 1.3 Mineo, S.; Gilfanov, M.; Lehmer, B. D.; Morrison, G. E.; Sunyaev, R. Abstract. We investigate the relation between total X-ray emission from star-forming galaxies and their star formation activity. Using nearby late-type galaxies and ultraluminous infrared galaxies from Paper I and star-forming galaxies from Chandra Deep Fields (CDFs), we construct a sample of 66 galaxies spanning the redshift range z ~ 0-1.3 and the star formation rate (SFR) range ~ 0.1-10^3^ M_sun_ yr^- 1^. In agreement with previous results, we find that the L_X_-SFR relation is consistent with a linear law both at z = 0 and for the z = 0.1-1.3 CDF galaxies, within the statistical accuracy of ~0.1 in the slope of the L_X_-SFR relation. For the total sample, we find a linear scaling relation L_X_/SFR ~ (4.0 +/- 0.4) x 10^39^(erg s^- 1^)/(M_sun_ yr^- 1^), with a scatter of ~0.4 dex. About ~2/3 of the 0.5-8 keV luminosity generated per unit SFR is expected to be due to high-mass X-ray binaries. We find no statistically significant trends in the mean L_X_/SFR ratio with the redshift or SFR and constrain the amplitude of its variations by <~ 0.1-0.2 dex. These properties make X-ray observations a powerful tool to measure the SFR in normal star-forming galaxies that dominate the source counts at faint fluxes.
