NGC2110
We propose to observe the Seyfert 2 galaxy NGC 2110 with XRISM for 80 ks. We aim at studying its Fe K complex, which is the sum of two components: one constant and narrow (originating from the circumnuclear torus) and the other one broad and with intensity linearly correlated with the source flux (possibly arising from the Broad Line Region which is hidden in the optical: the HBLR). The source is one of the brightest AGN in the 3-10 keV band and it has shown a clear, double-peaked Ha line in the polarized optical spectra. The unprecedented XRISM Resolve spectral energy resolution will allow us to investigate in detail the Fe Ka doublet and the Fe Kb emission lines arising from distant material and the broad component from gas in motion close to the black hole.
