资源简介:

We propose to observe the Seyfert 1 galaxy Mrk 290 for the first time withXMMNewton for a total exposure of 50 ks. Our main goals are: 1) study thedetails of the broad Fe line profile detected by ASCA, measure its parametersinferring limits on the black hole spin, and study its shorttimescalevariability and response to the continuum; 2) characterise at both CCD and RGSresolution the complex soft Xray spectrum where ASCA detected clear signaturesof warm absorber and possible emission lines; 3) use the expected Xrayvariability to unveil the main spectral components and their contribution to the(already observed) spectral variability. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
