Spectroscopic reverberation mapping of Quasar PKS 0736 + 017: broad-line region and black-hole mass

To understand the mass distribution and co-evolution of supermassive black holes with their host galaxy, it is crucial to measure hole AGN. Reverberation mapping a unique tool estimate masses in We performed spectroscopic reverberation study using long-term monitoring data more than 100 spectra radio-loud quasar PKS 0736+017 size broad line region (BLR) mass. The optical spectrum shows strong H$\mathrm{\beta}$ H$\mathrm{\gamma}$ emission lines. generated light curves 5100{\AA} continuum flux ($f_{5100}$), H$\beta$, H$\gamma$. All are found be strongly variable fractional variability 69$\%$, 21$\%$, 30$\%$ for V-band, H$\gamma$ curves, respectively. Along thermal contribution, non-thermal contributes estimated luminosity at 5100\AA. Using different methods, e.g., CCF, {\small JAVELIN}, von-neumann, we BLR, which 66.4$^{+6.0}_{-4.2}$ days rest frame. BLR combined width H$\beta$ provides 7.32$^{+0.89}_{-0.91} \times 10^{7}M_{\odot}$. source closely follows size-luminosity relation
