Arxiv: A distance measurement of galaxies from JWST using star formation rate-stellar mass relation Published: 11/29/2024 3:42:52 PM Updated: 11/29/2024 3:42:52 PM
Paper abstract: We use the star formation rate-stellar mass relation (SFR - {M_ * }) ofgalaxies to measure their luminosity distances as well as estimate cosmologicalparameters. We obtain a sample of 341 high-redshift galaxies at 5 < z < 14,and 51 others at 1.8 < z < 3.5 from the JWST observations, which can be usedto investigate the correlation between the star formation rate and stellarmass, and determine their cosmological distance. The relation SFR \propto{\kern 1pt} {({M_ * }/{M_ \odot })^\gamma } can be applied to check thenonlinear correlation between the star formation rate and stellar mass {M_ *} of galaxies and give their distance. On the other hand, it also can be usedto test if the SFR - {M_ * } relation depends on the absolute UV magnitude{M_{UV}}, and the data suggest that the SFR is positively correlated withstellar mass, the SFR - {M_ * } relation of the high-redshift galaxies has anabsolute magnitude dependence. Finally, we apply a combination of galaxies andType Ia supernova (SNIa) Pantheon to test the property of dark energyconcerning whether or not its density deviates from the constant, and give thestatistical results.
