NICER sees the contraction of the corona in a black hole X-ray transient (14 Jan 2019) NICER made the cover of Nature with an analysis by Kara et al. of the temporal behavior of the X-ray spectrum of the black hole transient system MAXI J1820+070. Their analysis of the time-resolved NICER spectra of this system showed that the inner edge of the accretion disk is near the accreting black hole and that variations in the X-ray spectral lags indicated that the corona shrank over a time interval of a few weeks. Updated Million Quasars Catalog (v5.7) (07 Jan 2019) The latest version (v5.7, 7 January 2019) of the Million Quasars (MILLIQUAS) Catalog (Eric Flesch 2009 - 2018) containing a lot more than one million (1,983,749 to be exact) likely quasars is now available in both Browse and Xamin.
