Accurate estimators of power spectra in N-body simulations
Stephane Colombi, Andrew H. Jaffe, Dmitri Novikov +1
abridged] A method to rapidly estimate the Fourier power spectrum of a point distribution is presented. This method relies on a Taylor expansion of the trigonometric functions. It…
Radio observations of the CDF-South: a possible link between radio emission and star formation in X-ray selected AGN
E. Rovilos, A. Georgakakis, I. Georgantopoulos +4
We explore the nature of the radio emission of X-ray selected AGN by combining deep radio (1.4GHz; 60micro-Jy) and X-ray data with multiwavelength (optical, mid-infrared) observati…
X-ray selected starbursts in the GOODS-North
A. Georgakakis, M. Rowan-Robinson, T. S. R. Babbedge +1
We investigate claims that recent deep X-ray surveys are detecting starbursts at cosmologically interesting redshifts (z=0-1). We combine X-ray data from the 2Ms CDF-North with mul…
The evolution of magnetic tower jets in the laboratory
A. Ciardi, S. V. Lebedev, A. Frank +12
The evolution of laboratory produced magnetic jets is followed numerically through three-dimensional, non-ideal magnetohydrodynamic simulations. The experiments are designed to stu…
Chandra and Spitzer observations of CDFS X-ray obscured QSOs
I. Georgantopoulos, A. Georgakakis, A. Akylas
We present Chandra and Spitzer data of the 186, extragalactic, hard 2-10 keV X-ray selected sources, which lie in the central part of the Chandra Deep Field South (CDFS). For the v…
The opaque nascent starburst in NGC 1377: Spitzer SINGS observations
H. Roussel, G. Helou, J. D. Smith +16
We analyze extensive data on NGC1377 from the Spitzer Infrared Nearby Galaxies Survey (SINGS). Within the category of nascent starbursts, that we previously selected by their infra…
