    • Multiband optical-NIR variability of blazars on diverse time-scales 

      Agarwal, Aditi; Böttcher, M.; Gupta, Alok C.; Bachev, R.; Strigachev, A. (Oxford University Press, 2015)
      To search for optical variability on awide range of time-scales,we have carried out photometric monitoring of two flat spectrum radio quasars, 3C 454.3 and 3C 279, plus one BL Lac, S5 0716+714, all of which have been ...
    • Nature of intranight optical variability of BL Lacertae 

      Gaur, Haritma; Böttcher, M.; Gupta, Alok C.; Bachev, R.; Strigachev, A. (Oxford University Press, 2015)
      We present the results of extensive multiband intranight optical monitoring of BL Lacertae during 2010–2012. BL Lacertae was very active in this period and showed intense variability in almost all wavelengths. We extensively ...
