英文摘要We have identified 105 galaxy pairs at z similar to 0.04 with the MaNGA integral-field spectroscopic data. The pairs have projected separations between 1 and 30 kpc, and are selected to have radial velocity offsets less than 600 km s(-1) and stellar mass ratio between 0.1 and 1. The pair fraction increases with both the physical size of the integral-field unit and the stellar mass, consistent with theoretical expectations. We provide the best-fit analytical function of the pair fraction and find that similar to 3% of M* galaxies are in close pairs. For both isolated galaxies and paired galaxies, active galactic nuclei (AGNs) are selected using emission-line ratios and Ha equivalent widths measured inside apertures at a fixed physical size. We find AGNs in similar to 24% of the paired galaxies and binary AGNs in similar to 13% of the pairs. To account for the selection biases in both the pair sample and the MaNGA sample, we compare the AGN comoving volume densities with those expected from the mass- and redshift-dependent AGN fractions. We find a strong (similar to 5x) excess of binary AGNs over random pairing and a mild (similar to 20%) deficit of single AGNs. The binary AGN excess increases from similar to 2x to similar to 6x as the projected separation decreases from 10-30 to 1-10 kpc. Our results indicate that the pairing of galaxies preserves the AGN duty cycle in individual galaxies but increases the population of binary AGNs through correlated activities. We suggest tidally induced galactic-scale shocks and AGN cross-ionization as two plausible channels to produce low-luminosity narrow-line-selected binary AGNs.
