Joint Analysis of Optical, Near-infrared, and Mid-infrared Variability of Four Quasars at Redshift <1

Amid rapid advances in time-domain astronomy, multiwavelength (e.g., optical and infrared) time-domain studies of quasars remain scarce. Here, we present a systematic analysis of four quasars initially selected by their Ks -band variability amplitudes in the VISTA Variables in the Vía Láctea Survey...
