With the exquisite wide and deep imaging from the Hyper Suprime-Cam Subaru Strategic Program, we have identified a population of 386 SDSS quasars as having two bright and separate components that are candidates for dual supermassive black holes, many of which are within the same host galaxy, likely the result of a major merger. For eleven candidates that have the closest separation at z>1, HST is needed to spectroscopically confirm their nature and their redshift by detection of broad emission lines from both objects. The high sensitivity of HST would further help us to rule out the possibility of lensing. Any confirmed physical quasar pair from our candidates would be the first case ever confirmed that has a projected separation below 6 kpc beyond z>1. This sample will be the key to understanding the merger process and how it affects galaxy evolution and AGN activity, since they are at close to final coalescence stage. Furthermore, this program will provide remarkable laboratories for studying the fueling of dual supermassive black holes with ALMA study. Moreover, taken together with the wider separation dual quasars confirmed by ground-based observations, we will measure the dual quasar fraction and its evolution up to z~3. The results will be compared with the predictions from recent hydrodynamic cosmological simulations. In this program, we use in total 12 orbits of WFC3/IR (G141 or G102) to confirm the nature of 11 dual AGN candidates. We plan to use the same procedure as used in GLASS, 3D HST, and the GO-13732 program: we first take a short exposure for F105W/F140W, and then a longer grism exposure for G102/G141. The sub-pixel pattern dither is adopted to obtain better spatial resolution in data reduction. The direction of the grism dispersion is taken to be perpendicular as much as possible to the duals to resolve their light. Ding has experience with high redshift AGNs using HST observations. He performed extensive and realistic simulations of high-z quasars based on HST. To unveil the correlations between the black hole and host galaxies at z>1, he utilizes 2D image analysis tools to estimate the host galaxy's luminosity by removing the bright AGN light. Also, he has experience with modeling the strong lensed quasars observed by HST. Silverman is the PI of a Cycle 25 proposal using WFC3 in imaging mode to detect the host galaxies of 32 AGN with 1 < z < 2. He has much experience with optical and near-infrared spectroscopy, in particular, using the Fiber Multi-Object Spectrograph (FMOS) on Subaru Telescope. He has many published studies on AGNs. Treu has plenty of experience working with the HST grisms. He was the PI of the GLASS program, which obtained grism data for 10 clusters of galaxies, and resulted in timely public data releases and close to 70 publications from the team and the community. He has been CoI of multiple grism programs with HST including 2 devoted to the study of lensed quasars. He has also 2 decades of experience in the field of AGN, primarly in the determination of black hole masses and the co-evolution of black holes and galaxies. Many of the additional investigators have experience with HST observations including Michael Strauss, Nao Suzuki and Anna Nierenberg.
