Approximations to path integrals and spectra of quantum systems
S. I. Blinnikov, N. V. Nikitin
An expression for the Green function G(E;x_1,x_2) of the Schroedinger equation is obtained through the approximations of the path integral by n-fold multiple integrals. The approxi…
The Large-Scale Tidal Velocity Field
Y. Hoffman, A. Eldar, S. Zaroubi +1
We present a method for decomposing the cosmological velocity field in a given volume into its divergent component due to the density fluctuations inside the volume, and its tidal…
Cosmic Shear and Clusters of Galaxies
Y. Mellier, L. van Waerbeke, T. Erben +9
The first detections of cosmic shear signal reported recently by 4 independent groups cover angular scales between one and 10 arcmin. On those scales, the cosmic shear is a signatu…
A Numerical Study of Cosmic Shear Statistics
A. Thion, Y. Mellier, F. Bernardeau +3
We explore the stability of the variance and skewness of the cosmic gravitational convergence field, using two different approaches: first we simulate a whole MEGACAM survey (100 s…
Cosmic Shear with the VLT
R. Maoli, Y. Mellier, L. van Waerbeke +5
We report on the detection of cosmic shear on angular scales of 1.3-6.5 arcmin using 45 independent empty fields observed with the Very Large Telescope (VLT). This result confirms…
The enigmatic soft X-ray NLS1 RX J0134.2-4258
D. Grupe, K. M. Leighly, H. -C. Thomas +1
We report the discovery and analysis of the follow-up ROSAT pointed observation, an ASCA observation and optical and radio observations of the enigmatic Narrow-Line Seyfert 1 galax…
