  • 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 ...
