There have been the approximate analytic solution \cite{Silveria} and several approximate analytic forms \cite{0508156,Carroll,0303112} of the growth factor for the general…
Imaging an Event Horizon: submm-VLBI of a Super Massive Black Hole
Sheperd Doeleman, Eric Agol, Don Backer +20
A long standing goal in astrophysics is to directly observe the immediate environment of a black hole with angular resolution comparable to the event horizon. Realizing this goal w…
Detailed Cluster Mass and Light profiles of A1703, A370 and RXJ1347-11 from Deep Subaru Imaging
Elinor Medezinski, Tom Broadhurst, Keiichi Umetsu +3
Weak lensing work can be badly compromised by unlensed foreground and cluster members which dilute the true lensing signal. We show how the lensing amplitude in multi-colour space…
