Very small-scale clustering of quasars from a complete quasar lens survey    [PDF]

Issha Kayo, Masamune Oguri

We measure the small-scale (comoving separation 10 kpc/h < r_p < 200 kpc/h) two-point correlation function of quasars using a sample of 26 spectroscopically confirmed binary quasars at 0.6 30), which may be suggestive of enhanced quasar activities by direct interactions.
