Microlensing induced spectral variability in Q2237+0305
We present both photometry and spectra of the individual images of the quadruple gravitational lens system Q2237+0305. Comparison of spectra obtained at two epochs, separated by ∼ 3 years, shows evidence for significant changes in the emission line to continuum ratio of the strong ultraviolet CIV λ1549, CIII] λ1909 and MgII λ2798 lines. The short, ∼ 1 day, light–travel time differences between ...
متن کاملVariability in Low Ionization Broad Absorption Line outflows
We present results of our time variability studies of Mg II and Al III absorption lines in a sample of 22 Low Ionization Broad Absorption Line QSOs (LoBAL QSOs) at 0.2 ≤ zem ≤ 2.1 using the 2-m telescope at IUCAA Girawali Observatory over a time-scale of 10 d to 7.69 years in the QSO’s rest frame. Spectra are analysed in conjunction with photometric light curves from Catalina Real-Time Transien...
متن کاملExtreme Variability in a Broad Absorption Line Quasar
CRTS J084133.15+200525.8 is an optically bright quasar at z = 2.345 that has shown extreme spectral variability over the past decade. Photometrically, the source had a visual magnitude of V ∼ 17.3 between 2002 and 2008. Then, over the following five years, the source slowly brightened by approximately one magnitude, to V ∼ 16.2. Only ∼ 1 in 10,000 quasars show such extreme variability, as quant...
متن کاملTerm Optical Variability in Broad Absorption Line QSOs
We present the first results from a pilot programme to monitor the short term optical variability in Broad Absorption Line system QSOs. Intra-night optical variations of ∼ 5% were detected on time scales of ∼ one hour in QSOs 0846+156 and 0856+172. Further, the mean magnitude level decreased in the two objects by ∼ 0.05 and ∼ 0.15 magnitude respectively during the period of our observations. Th...
متن کاملNew Constraints on Quasar Broad Absorption and Emission Line Regions from Gravitational Microlensing
Gravitational microlensing is a powerful tool allowing one to probe the structure of quasars on sub-parsec scale. We report recent results, focusing on the broad absorption and emission line regions. In particular microlensing reveals the intrinsic absorption hidden in the P Cygni-type line profiles observed in the broad absorption line quasar H1413+117, as well as the existence of an extended ...
