X-ray monitoring of gravitationally lensed radio-loud quasars with Chandra
Mustafa Burak Dogruel, Xinyu Dai, Eduardo Guerras +2
In this work, we calculated the sizes of unresolved X-ray emission regions in three gravitationally lensed radio-loud quasars, B\,1422+231, MG\,J0414+0534 and Q\,0957+561, using a…
COSMOGRAIL XVIII: time delays of the quadruply lensed quasar WFI2033-4723
V. Bonvin, M. Millon, J. H. H. Chan +26
We present new measurements of the time delays of WFI2033-4723. The data sets used in this work include 14 years of data taken at the 1.2m Leonhard Euler Swiss telescope, 13 years…
Time Delay and Accretion Disk Size Measurements in the Lensed Quasar SBS 0909+532 from Multiwavelength Microlensing Analysis
Laura J. Hainline, Christopher W. Morgan, Chelsea L. MacLeod +7
We present three complete seasons and two half-seasons of SDSS r-band photometry of the gravitationally lensed quasar SBS 0909+532 from the U.S. Naval Observatory, as well as two s…
Further Evidence that Quasar X-Ray Emitting Regions Are Compact: X-Ray and Optical Microlensing in the Lensed Quasar Q J0158-4325
Christopher W. Morgan, Laura J. Hainline, Bin Chen +9
We present four new seasons of optical monitoring data and six epochs of X-ray photometry for the doubly-imaged lensed quasar Q J0158-4325. The high-amplitude, short-period microle…
A New Microlensing Event in the Doubly-Imaged Quasar Q0957+561
Laura J. Hainline, Christopher W. Morgan, J. N. Beach +6
We present evidence for ultraviolet/optical microlensing in the gravitationally lensed quasar Q0957+561. We combine new measurements from our optical monitoring campaign at the Uni…
