Scientific paper

We propose to double the number of SDSS Type 2 quasar candidates with sensitive X-ray coverage by observing 12 luminous narrow-line AGN at z=0.40-0.73 with Chandra. These observations will confirm whether these sources are genuine obscured quasars (NH>10^22 cm^-2; L(2-10 keV)>10^44 erg/s) through basic X-ray spectral fitting and stacking analyses. Although past investigations have shown that >50% of the SDSS Type 2 quasars have NH>10^22-10^23 cm^-2, with the remaining sources being possibly more obscured, statistical analyses have been challenged by the small number of sources available. With the proposed observations, we will observe all of the SDSS Type 2 quasar candidates with L(2-10 keV)>4x10^44 erg/s.
