Deficit of Luminous and Normal Red Galaxies in Cosmic Voids
Sean Bruton, Xinyu Dai, Eduardo Guerras +1
We construct a sample of 10,680 wall galaxies and 3,064 void galaxies with by cross referencing a void catalog from literature with Baryon Oscillation Spectrosco…
Confirmation of Planet-Mass Objects in Extragalactic Systems
Saloni Bhatiani, Xinyu Dai, Eduardo Guerras
Quasar microlensing serves as a unique probe of discrete objects within galaxies and galaxy clusters. Recent advancement of the technique shows that it can constrain planet-scale o…
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…
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…
Constraining Quasar Relativistic Reflection Regions and Spins with Microlensing
Xinyu Dai, Shaun Steele, Eduardo Guerras +2
We present an analysis of Chandra spectra of five gravitationally lensed active galactic nuclei. We confirm the previous detections of FeK emission lines in most images of these…
