Active Galactic Nuclei Abundance in Cosmic Voids
H. D. Mishra, X. Dai, E. Guerras
The abundance of active galactic nuclei (AGN) in cosmic voids is relatively unexplored in the literature, but can potentially provide new constraints on the environmental dependenc…
Individual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad Line Region
E. Mediavilla, J. Jiménez-Vicente, J. Mejí A-Restrepo +5
Assuming a gravitational origin for the Fe III2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we obtain individual me…
The Vanishing & Appearing Sources during a Century of Observations project: I. USNO objects missing in modern sky surveys and follow-up observations of a "missing star"
Beatriz Villarroel, Johan Soodla, Sébastien Comerón +19
In this paper we report the current status of a new research program. The primary goal of the "Vanishing & Appearing Sources during a Century of Observations" (VASCO) project is to…
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…
