H$\alpha$ Reverberation Mapping from Broad-band Photometry of Dwarf Seyfert 1 Galaxy NGC 4395

Autor: Gu, Huapeng, Wu, Xue-Bing, Wen, Yuhan, Ma, Qinchun, Guo, Hengxiao

NGC 4395 is a dwarf Seyfert 1 galaxy with a possible intermediate-mass black hole of several $\rm{10^4}$ solar masses in its center. As a well-studied object, its broad line region size has been measured via H$\rm{\alpha}$ time lag in numerous spectr

Evidence for an Outer Component in the Continuum Reverberation Mapping of Active Galactic Nuclei

Autor: Jiang, Yuanzhe, Wu, Xue-Bing, Ma, Qinchun, Gu, Huapeng, Wen, Yuhan

The continuum reverberation mapping is widely used in studying accretion disk of active galactic nuclei (AGN). While some indirect evidence and simulations indicated that the diffuse continuum, especially the strong Balmer continuum from the broad li

H$\alpha$ Time Delays of AGNs from the Zwicky Transcient Facility Broadband Photometry

Autor: Ma, Qinchun, Wen, Yuhan, Wu, Xue-Bing, Gu, Huapeng, Fu, Yuming

In our previous work on broadband photometric reverberation mapping (PRM), we proposed the ICCF-Cut process to obtain the time lags of H$\alpha$ emission line from two broadband lightcurves via subtracting the continuum emission from the line band. E

The H$\alpha$ broadband photometric reverberation mapping of four Seyfert 1 galaxies

Autor: Ma, Qinchun, Wu, Xue-Bing, Gu, Huapeng, Wen, Yuhan, Fu, Yuming

Broadband photometric reverberation mapping (PRM) have been investigated for AGNs in recent years, but mostly on accretion disk continuum RM. Due to the small fraction of broad emission lines in the broadband, PRM for emission lines is very challengi
