In the next years the Vera C. Rubin Observatory Legacy Survey of Space and Time (Rubin-LSST) will produce the deepest and widest image of the sky in the Southern hemisphere, opening a window of discovery on the dynamic Universe.
In particular, the ten-year survey will offer an unprecedented opportunity to study in detail the variability of blazars, active galactic nuclei with a relativistic jet closely aligned with our line of sight.
In this new paper by Claudia M. Raiteri, Maria I. Carnerero, Barbara Balmaverde, Massimo Villata (INAF-OATo) et al., the authors examine the simulated LSST survey strategies with the aim of understanding which ones are more suitable for blazar variability science, providing recommendations for the choice of the Rubin-LSST cadence.
They also investigate the problem of saturation in the LSST images, which will affect the brightest and many flaring sources.
The paper has been accepted for publication in ApJS.
