The Angular Clustering of WISE-Selected AGN: Different Haloes for Obscured and Unobscured AGN

Donoso, E., Yan, Lin, Stern, D. et al.

Understand

We calculate the angular correlation function for a sample of 170,000 AGN extracted from the Wide-field Infrared Survey Explorer (WISE) catalog, selected to have red mid-IR colors (W1 - W2 > 0.8) and 4.6 micron flux densities brighter than 0.14 mJy).

The sample is expected to be >90% reliable at identifying AGN, and to have a mean redshift of z=1.1.
In total, the angular clustering of WISE-AGN is roughly similar to that of optical AGN.
We cross-match these objects with the photometric SDSS catalog and distinguish obscured sources with (r - W2) > 6 from bluer, unobscured AGN.
