Description
We have performed the analysis of the X-ray XMM-Newton spectra of the narrow line Seyfert 1 galaxy UGC 11763 (Mkn 1513). We have studied the EPIC data in the range 0.35-10.0 keV (1.2-35.4 Å) and also the high resolution soft X-ray spectra taken with the Reflection Grating Spectrometers (RGSs) in the range 10-30 Å (0.41-1.2 keV). The principal feature observed in the hard X-ray spectrum is a weak Fe-Kalpha fluorescence line. The soft X-ray spectra are characterised by absorption features. The most significant of them is the one between 15 and 18 Å (in the rest frame of the object). We have identified this broad absorption with the UTA (unresolved transition array) produced by Fe M-shell transitions which was reported for the first time by Sako et al. (2001), and that is indicative of the presence of absorbing material in the vicinity of the active nucleus.

    NIRPS is a fiber-fed AO nIR spectrograph working simultaneously with HARPS at the La Silla-ESO 3.6m telescope. The cryogenic spectrograph operating at 75K employs a cross-dispersed echelle grating (R4), covering a wavelength range of 0.98-1.80 microns in a single image using a Teledyne Hawaii-4RG infrared detector. In early 2022, the NIRPS
