两微米全天巡天 (2MASS) 为在其他波长发现的活动星系核大样本提供了前所未有的统一光度数据集,也为搜索以前未知的模糊活动星系核奠定了基础。我们展示了使用 2MASS 进行的基于近红外颜色的高效 AGN 调查的结果,该调查已经发现了 485 个新的红色 AGN 和 QSO。当 K s ≤ 15.5 mag 时,2MASS 红色 AGN 的外推表面密度为 ~0.57 deg~ -2。新发现的天体中1型与2型活动星系核的比例为4:1,与X射线和深度ISO调查中发现的比例相似,但与IRAS调查中发现的比例相反。新的 2MASS 红色 AGN 样本的中值红移为 z
The Two Micron All Sky Survey (2MASS) provides an unprecedented, uniform photometric data set for large samples of AGN discovered at other wavelengths, and also forms the basis to search for previously unknown, obscured AGN. We present the results of a highly efficient near infrared color-based AGN survey using 2MASS that has already discovered 485 new, red AGN and QSOs. The extrapolated surface density of the 2MASS red AGN is ~0.57 deg~ −2 for K s ≤15.5 mag. The ratio of Type 1 to Type 2 AGN among the newly discovered objects is 4:1, similar to proportions found in X-ray and deep ISO surveys, but the inverse of that found in IRAS surveys. The median redshift of the the new 2MASS red AGN sample is z
