Abstract NGC 2617 attracted a lot of attention after the detection changes in its spectral type; geometry and kinematics broad-line region (BLR) are still ambiguous. In this paper, we present high cadence (?2 days) reverberation mapping campaign from 2019 October to 2020 May unde
We have modeled the full velocity-resolved reverberation response of Hβ and He ii optical broad emission lines in NGC 3783 to constrain geometry kinematics low-ionization high-ionization broad-line region (BLR). The is found be a thick disk that nearly face-on, inclined at ∼18° o
Changing-look active galactic nucleus NGC~4151, which has attracted a lot of attention, is undergoing the second dramatic outburst stage in its evolutionary history. To investigate geometry and kinematics broad-line region (BLR), measure mass supermassive black hole we perform se
We present the first ~7.5'×11.5' velocity-resolved (~0.2 km s-1) map of the [C ii] 158 μm line toward the Orion molecular cloud 1 (OMC 1) taken with the Herschel/HIFI instrument. In combination with far-infrared (FIR) photometric images and velocity-resolved maps of the H41α hydr
