The M_BH-M_star relation of obscured AGNs at high redshift

Understand

We report the detection of broad Halpha emission in three X-ray selected obscured AGNs at z=1-2.

• By exploiting the Halpha width and the intrinsic X-ray luminosity, we estimate their black hole masses, which are in the range 0.1-3x10^9 Msun.
• By means of multi-band photometric data, we measure the stellar mass of their host galaxy and, therefore, infer their M_BH/M_star ratio.
• These are the first obscured AGNs at high-z, selected based on their black hole accretion (i.e.
