A characteristic optical variability timescale in astrophysical accretion disks
Colin J. Burke, Yue Shen, Omer Blaes +8
Accretion disks around supermassive black holes in active galactic nuclei produce continuum radiation at ultraviolet and optical wavelengths. Physical processes in the accretion fl…
Resolving the inner accretion flow towards the central supermassive black hole in SDSS J1339+1310
V. N. Shalyapin, L. J. Goicoechea, C. W. Morgan +2
We studied the accretion disc structure in the doubly imaged lensed quasar SDSS J1339+1310 using -band light curves and UV-visible to near-IR (NIR) spectra from the first 11 obs…
Near infrared and optical continuum emission region size measurements in the gravitationally lensed quasars Q0957+561 and SBS0909+532
Matthew A. Cornachione, Christopher W. Morgan, Hayden R. Burger +5
We present a microlensing analysis of updated light curves in three filters, --band, --band, and --band, for the gravitationally lensed quasars Q0957+561 and SBS0909+532.…
The Most Powerful Lenses in the Universe: Quasar Microlensing as a Probe of the Lensing Galaxy
David Pooley, Timo Anguita, Saloni Bhatiani +14
Optical and X-ray observations of strongly gravitationally lensed quasars (especially when four separate images of the quasar are produced) determine not only the amount of matter…
Astro2020 Science White Paper - Quasar Microlensing: Revolutionizing our Understanding of Quasar Structure and Dynamics
Leonidas Moustakas, Matthew O'Dowd, Timo Anguita +20
Microlensing by stars within distant galaxies acting as strong gravitational lenses of multiply-imaged quasars, provides a unique and direct measurement of the internal structure o…
Accretion Disk Size Measurement and Time Delays in the Lensed Quasar WFI 2033-4723
Christopher W. Morgan, Gregory E. Hyer, Vivien Bonvin +5
We present 13 seasons of -band photometry of the quadruply-lensed quasar WFI 2033-4723 from the 1.3m SMARTS telescope at CTIO and the 1.2m Euler Swiss Telescope at La Silla, in…
