New Structure In The Shapley Supercluster
M. J. Drinkwater, D. Proust, Q. A. Parker +2
We present new radial velocities for 306 bright (R<16) galaxies in a 77 square deg region of the Shapley supercluster measured with the FLAIR-II spectrograph on the UK Schmidt Tele…
On the minimum period of uniformly rotating meutron stars
P. Haensel, J. P. Lasota, J. L. Zdunik
We show that the neutron star minimum period of rotation is determined, for causal equations of state, by the maximum value of the relativistic (compactness) parameter 2GM/Rc^2, al…
Follow up of the CFRS with HST, ISO and VLA: the cosmic star formation rate as derived from the FIR luminosity density
F. Hammer, H. Flores
Properties of CFRS field galaxies up to z=1 are discussed. Estimations of the cosmic star formation rate (SFR) lead to serious problems if they not account for AGN emissions and fo…
Preliminary results of dark-speckle stellar coronography
A. Boccaletti, A. Labeyrie, R. Ragazzoni
The dark-speckle method (Labeyrie 1995) combines features of speckle interferometry and adaptive optics to provide images of faint circumstellar material. We present preliminary re…
A Morphological Indicator for Comparing Simulated Cosmological Scenarios with Observations
E. Lega, A. Bijaoui, J. -M. Alimi +1
We propose a morphological multi-scale analysis of large-scale structures obtained by computer simulations and by observations. Structures are obtained at different scales by apply…
