cds-question@unistra.frquasarsx-ray-sourcesblack-holesredshiftedvisible-astronomyradio-sourcesWe investigate whether the correlation between the hard X-ray photon index ({Gamma}) and accretion rate for super-Eddington accreting quasars is different from that for sub-Eddington accreting quasars. We construct a sample of 113 bright quasars from the Sloan Digital Sky Survey Data Release 14 quasar catalog, with 38 quasars as the super-Eddington subsample and 75 quasars as the sub-Eddington subsample. We derive black hole masses using a simple-epoch virial mass formula based on the H{beta} lines, and we use the standard thin disk model to derive the dimensionless accretion rates (M) for our sample. The X-ray data for these quasars are collected from the Chandra and XMM-Newton archives. We fit the hard X-ray spectra using a single power-law model to obtain {Gamma} values. We find a statistically significant (R_S_=0.43, p=7.75x10^-3^) correlation between {Gamma} and M for the super-Eddington subsample. The {Gamma}-M correlation for the sub-Eddington subsample is also significant, but weaker (R_S_=0.30, p=9.98x10^-3^). Linear regression analysis shows that {Gamma}=(0.34{+/-}0.11)log(M)+(1.71{+/-}0.17) and {Gamma}=(0.09{+/-}0.04)log(M)+(1.93{+/-}0.04) for the super- and sub-Eddington subsamples, respectively. The {Gamma}-M correlations of the two subsamples are different, suggesting different disk-corona connections in these two types of systems. We propose one qualitative explanation of the steeper {Gamma}-M correlation in the super-Eddington regime that involves larger seed photon fluxes received by the compact coronae from the thick disks in super-Eddington accreting quasars.2020ApJ...895..114Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/895/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/51 : the FIRST Survey, version 1998Feb (White+ 1998)VIII/59 : the FIRST Survey, version 1999Jul (White+ 1999)VIII/71 : The FIRST Survey Catalog, Version 03Apr11 (Becker+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)VIII/90 : The FIRST Survey Catalog, Version 12Feb16 (Becker+ 2012)VII/286 : SDSS quasar catalog, fourteenth data release (Paris+, 2018)J/AJ/131/2766 : Quasar luminosity function from SDSS-DR3 (Richards+, 2006)J/ApJS/165/1 : BAL QSOs from SDSS DR3 (Trump+, 2006)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)J/ApJ/692/758 : BAL QSOs in SDSS-DR5 (Gibson+, 2009)J/A+A/493/339 : XMM-Newton serendipitous Survey.
