  • Multi-band behaviour of the TeV blazar PG 1553+113 in optical range on diverse timescales 
    Agarwal, A; Mihov, B; Andruchow, I; Cellone, S. A; Anupama, G. C; Agrawal, V; Zola, S; Slavcheva, L; Slavcheva-Mihova, L; Ozdonmez, A; Ege, Ergun; Raj, A; Mammana, L; Zibecchi, L; Fernandez-Lajus, E (EDP Sciences, 2021-01)
    Context. The TeV BL Lac object PG 1553+113 is one of the primary candidates for a binary supermassive black hole system. Aims. We study the flux and spectral variability of PG 1553+113 on intra-night to long-term ...

    Aditi Agarwal; Cellone, Sergio A; Andruchow, I; Mammana, Luis; Singh, Mridweeka; Anupama, G. C; Mihov, B; Raj, A; eva-Mihova, L; Ozdonmez, Aykut; Ege, Ergun (Oxford University Press on behalf of the Royal Astronomical Society, 2019-09)
    We have monitored the flat spectrum radio quasar, 3C 279, in the optical B, V, R, and I passbands from 2018 February to 2018 July for 24 nights, with a total of 716 frames, to study flux, colour, and spectral variability ...
  • Optical flux and spectral characterization of the blazar PG 1553 + 113 based on the past 15 years of data 
    Agarwal, Aditi; Mihov, B; Andruchow, I; Cellone, Sergio A; Anupama, G. C; Agrawal, V; Zola, S; Ergun Ege; Özdönmez, Aykut; Ege, Ergün (Indian Academy of Sciences, 2022-06)
    We study flux and spectral variability of the high energy peaked TeV blazar PG 1553 + 113 on diverse timescales using the data collected from 2005 to 2019 which also includes the intensive intra-night monitoring of the ...
