Dark matter halos of luminous AGNs from galaxy-galaxy lensing with the HSC Subaru Strategic Program

Understand

We assess the dark matter halo masses of luminous AGNs over the redshift range 0.2 to 1.2 using galaxy-galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP).

• We measure the weak lensing signal of a sample of 48907 AGNs constructed using HSC and WISE photometry.
• %The lensing detection around AGNs has a signal to noise ratio of \textbf{29}.
• As expected, we find that the lensing mass profile of total AGN sample is consistent with that of massive galaxies ($\rm log(M_{*}/h^{-2}M_\odot)\sim$ 10.61).
