Data

XMM-Newton: 

The sample of 15 QSOs - 26 separated observations for a total of 2.3 Ms - will be observed over 3 Cycles: AO23-24-25, starting May 2024 and ending April 2027, with a similar total exposure time per year. The targets have been sorted in decreasing flux/increasing exposure time order (the goal is to reach the same data quality for all fluxes). Therefore, during the first year (AO23), we will observe the 7 brightest targets.

Nustar:

The program approved in Cycle 10 granted deep observations (60-130ks) for the first 7 targets, to be observed by XMM in AO23. The observations will be carried out in coordination between the two telescopes - within a few weeks, roughly corresponding to the rest-frame light travel time for a 10 Rg emitting region, given the BH mass and redshift of the targets - to minimize the impact of spectral variability.

UV rest-frame spectra:

We have collected co-eval (within a few weeks from the XMM pointings) UV rest-frame spectra thanks to Subaru/FOCAS observations (PI. Toru Misawa) and Palomar DBSP (PI. Dan Stern) to investigate the possible connection between UV absorbers and X-ray Ultra Fast Outflows.
