Intra-day variability of BL Lacertae from 2016 to 2018
نویسندگان
چکیده
Abstract We monitored BL Lacertae in the B , V R and I bands for 14 nights during period of 2016–2018. The source showed significant intra-day variability on 12 nights. performed color-magnitude analysis found that exhibited bluer-when-brighter chromatism. This behavior is at least partly caused by larger variation amplitude shorter wavelengths. variations different wavelengths are correlated well show no inter-band time lag.

The long-term optical spectral variability of BL Lacertae
Context. We present the results from a study of the long-term optical spectral variations of BL Lacertae, using the long and wellsampled B and R-band light curves of the Whole Earth Blazar Telescope (WEBT) collaboration, binned on time intervals of 1 day. Aims. To study the relation between the long-term spectral variations and the respective flux variations of the source. Methods. We use cross...
متن کاملBroadband Spectra and Variability of BL Lacertae in 2000
We have organized an extensive multiwavelength campaign on BL Lacertae in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio frequencies, in the optical — carried out by the WEBT collaboration —, in X-rays — using BeppoSAX and RXTE —, and at VHE gamma-rays with the CAT and HEGRA Cherenkov telescope facilities. In this paper, we are presenting first resu...
متن کاملModeling the Variability of the Bl Lacertae Object Pks 21552304
The bright X-ray–selected BL Lacertae object PKS 21552304 has been the target of two intense multiwavelength campaigns: in 1991 November and in 1994 May. Although the spectral energy distributions at both epochs were quite similar, the source exhibited two very distinct variability patterns that cannot be easily reconciled with homogeneous, one-zone jet models. During the first epoch the variab...
متن کاملVariability of the BL Lacertae Object PKS 2155 − 304
We present a detailed power density spectrum and cross-correlation analysis of the X-ray light curves of the BL Lac object PKS 2155−304 observed with BeppoSAX in 1997 (SAX97) and 1996 (SAX96), aimed at exploring the rapid variability properties and the inter-band cross correlations in the X-rays. We also perform the same analysis on the (archival) X-ray light curve obtained with ASCA in 1994 (A...
متن کاملUnusual radio variability in the BL Lacertae object 0235 + 164
We present radio observations at three frequencies and contemporaneous optical monitoring of the peculiar BL Lac object AO 0235+164. During a three-week campaign with the VLA we observed intraday variability in this source and found a distinct peak which can be identified throughout the radio frequencies and tentatively connected to the R-band variations. This event is characterized by unusual ...
