As one of the most interesting Seyfert 1 galaxies, PG 2130+099 has been the target of several reverberation mapping (RM) campaigns over the years. However, its measured broad Hβ line responses have been inconsistent, with time lags of ∼200 days, ∼25 days,
作为最有趣的赛弗特1型星系之一,PG 2130 + 099多年来一直是若干反响映射(RM)活动的目标。然而,其测量到的宽Hβ线响应一直不一致,时间延迟约为200天、约25天。
