Probing the accelerating Universe with radio weak lensing in the JVLA Sky Survey
M. L. Brown, F. B. Abdalla, A. Amara +48
We outline the prospects for performing pioneering radio weak gravitational lensing analyses using observations from a potential forthcoming JVLA Sky Survey program. A large-scale…
Optimized Principal Component Analysis on Coronagraphic Images of the Fomalhaut System
T. Meshkat, M. Kenworthy, S. P. Quanz +1
We present the results of a study to optimize the principal component analysis (PCA) algorithm for planet detection, a new algorithm complementing ADI and LOCI for increasing the c…
Model Breaking Measure for Cosmological Surveys
Adam Amara, Alexandre Refregier
Recent observations have led to the establishment of the concordance LCDM model for cosmology. A number of experiments are being planned to shed light on dark energy, dark matter,…
A Way Forward for Cosmic Shear: Monte-Carlo Control Loops
Alexandre Refregier, Adam Amara
Weak lensing by large scale structure or 'cosmic shear' is a potentially powerful cosmological probe to shed new light on Dark Matter, Dark Energy and Modified Gravity. It is based…
A young protoplanet candidate embedded in the circumstellar disk of HD100546
Sascha P. Quanz, Adam Amara, Michael R. Meyer +3
We present high-contrast observations of the circumstellar environment of the Herbig Ae/Be star HD100546. The final 3.8 micron image reveals an emission source at a projected separ…
