Flashlights: More than A Dozen High-Significance Microlensing Events of Extremely Magnified Stars in Galaxies at Redshifts z=0.7-1.5
Patrick L. Kelly, Wenlei Chen, Amruth Alfred +23
Once only accessible in nearby galaxies, we can now study individual stars across much of the observable universe aided by galaxy-cluster gravitational lenses. When a star, compact…
Flashlights: An Off-Caustic Lensed Star at Redshift = 1.26 in Abell 370
Ashish Kumar Meena, Wenlei Chen, Adi Zitrin +10
We report the discovery of a transient seen in a strongly lensed arc at redshift in \emph{Hubble Space Telescope} imaging of the Abell 370 galaxy cluster. The tr…
Strong Lensing by Galaxies
A. J. Shajib, G. Vernardos, T. E. Collett +7
Strong gravitational lensing at the galaxy scale is a valuable tool for various applications in astrophysics and cosmology. The primary uses of galaxy-scale lensing are to study el…
Statistical Mechanics of Collisionless Orbits. V. The approach to equilibrium for idealized self-gravitating systems
Liliya L. R. Williams, Jens Hjorth
Self-gravitating Newtonian systems consisting of a very large number of particles have generally defied attempts to describe them using statistical mechanics. This is paradoxical s…
An excursion into the core of the cluster lens Abell 1689
Agniva Ghosh, Dominic Adams, Liliya L. R. Williams +3
Abell 1689 is a well studied cluster of galaxies and one of the largest gravitational lens systems ever observed. We have obtained a reconstruction of the cluster Abell 1689 using…
