Generating AGN spectra for LSST: First steps

Swayamtrupta Panda, Bożena Czerny

In the near future the arrival of new surveys promises a significant increment in the number of quasars (QSO) at large redshifts. This will help to constrain the dark energy models using quasars. The Vera Rubin Observatory's main survey: Legacy Survey of Space and Time (LSST) will cover over 10 million QSO in six photometric bands during its 10-year run. QSO will be monitored and subsequently analysed using the photometric reverberation mapping technique. Oncoming LSST data will decrease the uncertainties in the dark energy determination using reverberating–mapped sources, particularly at high redshifts. We present the first steps in modelling of lightcurves for Hβ and MgII lines and discuss the quasar selection in the context of photometric reverberation mapping with LSST. With the onset of the LSST era, we expect a huge rise in the overall quasar count and redshift range covered (z≤7.0), which will provide a better constraint of AGN properties with cosmological purposes.
