Medium-resolution Optical and Near-Infrared Spectral Atlas of 16 2MASS-selected NIR-red Active Galactic Nuclei at $z\sim 0.3$

Abstract

We present medium-resolution spectra ($R\sim 2000$--4000) at 0.4--1.0\,$\mu$m and 0.7--2.5\,$\mu$m of 16 active galactic nuclei (AGNs) selected with red color in the near-infrared (NIR) of $J-K>2.0$ mag at $z\sim 0.3$. We fit the H$\beta$, H$\alpha$, P$\beta$, and P$\alpha$ lines from these spectra to obtain their luminosities and line widths. We derive the $E(B-V)$ color excess values of the NIR-red AGNs using two methods, one based on the line-luminosity ratios and another based on the continuum slopes. The two $E(B-V)$ values agree with each other at rms dispersion $\sim$ 0.249. About half of the NIR-red AGNs have $g^{\prime }-K<5$ magnitude, and we find that these NIR red, but blue in optical-NIR AGNs, have $E(B-V)\sim 0$, suggesting that a significant fraction of the NIR color-selected red AGNs are unobscured or only mildly obscured. After correcting for the dust extinction, we estimate the black hole (BH) masses and the bolometric luminosities of the NIR-red AGNs using the Paschen lines to calculate their Eddington ratios (${\lambda }_{\mathrm{Edd}}$). The median Eddington ratios of nine NIR-red AGNs ($\log ({\lambda }_{\mathrm{Edd}})\simeq -0.654\pm 0.176$) are only mildly higher than those of unobscured type 1 AGNs ($\log ({\lambda }_{\mathrm{Edd}})\simeq -0.961\pm 0.008$). Moreover, we find that the $M_{\mathrm{BH}}$--${\sigma }_{\ast }$ relation for three NIR-red AGNs is consistent with that of unobscured type 1 AGNs at similar redshift. These results suggest that the NIR red color selection alone is not effective at picking up dusty, intermediate-stage AGNs.
