Title A name given to the resource Mid-infrared variability of ?-ray emitting blazars Subject The topic of the resource BL Lacertae objects: general; Galaxies: active; Galaxies: jets; Infrared: galaxies Description An account of the resource Using data from the Wide-field Infrared Survey Explorer, we studied the mid-infrared (mid-IR) 3.4 ?m (W1-band) and 4.6 ?m (W2-band) flux variability of ? -ray emitting blazars. Our sample consists of 460 flat spectrum radio quasars (FSRQs) and 575 BL Lacertae (BL Lac) objects. On intraday time-scales, the median amplitude of variability (? m) for FSRQs is 0.04+0.03?0.02 and 0.05+0.03?0.02 mag in W1 and W2 bands. For BL Lacs, we found median ? m in W1(W2) bands of 0.04+0.01?0.02 (0.04+0.02?0.02) mag. On long time-scales, for FSRQs we found a median ? m of 0.44+0.28?0.27 and 0.45+0.27?0.27 mag in W1 and W2 bands, while for BL Lacs, the median values are 0.21+0.18?0.12 and 0.22+0.18?.011 mag in W1 and W2 bands. From statistical tests, we found FSRQs to show larger ? m than BL Lacs on both intraday and long time-scales. Among blazars, low synchrotron peaked sources showed larger ? m compared to intermediate synchrotron peaked and high synchrotron peaked sources. The larger ? m seen in FSRQs relative to BL Lacs on both intraday and long time-scales could be due to them having the most powerful relativistic jets and/or their mid-IR band coinciding with the peak of the electron energy distribution. BL Lacs have low power jets and the observational window too traces the emission from low-energy electrons, thereby leading to low ? m. In both FSRQs and BL Lacs predominantly a bluer when brighter behaviour was observed. No correlation is found between ? m and black hole mass. 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society Creator An entity primarily responsible for making the resource Anjum A.; Stalin C.S.; Rakshit S.; Gudennavar S.B.; Durgapal A.
