Long-term optical spectroscopic variations in blazar 3C 454.3
Krzysztof Nalewajko, Alok C. Gupta, Mai Liao +3
Characterisation of the long-term variations in the broad line region in a luminous blazar, where Comptonisation of broad-line emission within a relativistic jet is the standard sc…
Exploring the role of X-ray reprocessing and irradiation in the anomalous bright optical outbursts of A0538-66
L. Ducci, S. Mereghetti, K. Hryniewicz +2
In 1981, the Be/X-ray binary (Be/XRB) A0538-66 showed outbursts characterized by high peak luminosities in the X-ray and optical bands. The optical outbursts were qualitatively exp…
Time delay measurement of Mg II line in CTS C30.10 with SALT
Bozena Czerny, Aleksandra Olejak, Mateusz Ralowski +18
We report 6 yr monitoring of a distant bright quasar CTS C30.10 (z = 0.90052) with the Southern African Large Telescope (SALT). We measured the rest-frame time-lag of da…
