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.…
Quasar Microlensing Variability Studies Favor Shallow Accretion Disk Temperature Profiles
Matthew A. Cornachione, Christopher W. Morgan
We compare the microlensing-based continuum emission region size measurements in a sample of 15 gravitationally lensed quasars with estimates of luminosity-based thin disk sizes to…
A Microlensing Accretion Disk Size Measurement in the Lensed Quasar WFI 2026-4536
Matthew A. Cornachione, Christopher W. Morgan, Martin Millon +4
We use thirteen seasons of R-band photometry from the 1.2m Leonard Euler Swiss Telescope at La Silla to examine microlensing variability in the quadruply-imaged lensed quasar WFI 2…
Rest-frame UV Properties of Luminous Strong Gravitationally Lensed Ly Emitters from the BELLS GALLERY Survey

We present deep rest-frame UV spectroscopic observations using the Gran Telescopio Canarias of six gravitationally lensed Lya emitters (LAEs) at selected from the BEL…
A Full Implementation of Spectro-Perfectionism for Precise Radial Velocity Exoplanet Detection: A Test Case With the MINERVA Reduction Pipeline
Matthew A. Cornachione, Adam S. Bolton, Jason D. Eastman +10
We present a computationally tractable implementation of spectro-perfectionism, a method which minimizes error imparted by spectral extraction. We develop our method in conjunction…
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…
KELT-24b: A 5M Planet on a 5.6 day Well-Aligned Orbit around the Young V=8.3 F-star HD 93148
Joseph E. Rodriguez, Jason D. Eastman, George Zhou +76
We present the discovery of KELT-24 b, a massive hot Jupiter orbiting a bright (V=8.3 mag, K=7.2 mag) young F-star with a period of 5.6 days. The host star, KELT-24 (HD 93148), has…
The Most Powerful Lenses in the Universe: Quasar Microlensing as a Probe of the Lensing Galaxy
