Cooper pairing reexamined
M. Fortes, M. de Llano, M. A. Solis
When both two-electron \textit{and} two-hole Cooper-pairing are treated on an equal footing in the ladder approximation to the Bethe-Salpeter (BS) equation, the zero-total-momentum…
Rapid N_H changes in NGC 4151
S. Puccetti, F. Fiore, G. Risaliti +4
We have analyzed the two longest (elapsed time > 3 days) BeppoSAX observations of the X-ray brightest Seyfert galaxy, NGC 4151, to search for spectral variability on time-scales fr…
The global kinematics of the Dumbbell planetary nebula (NGC 6853, M27, PN G060.8-03.6)
J. Meaburn, P. Boumis, P. E. Christopoulou +3
Spatially resolved profiles of the HeII 6560 A, Halpha and [N II] 6548 & 6584 A nebular emission lines have been obtained in two orthogonal long cuts over the Dumbbell planetary ne…
Total Opacity of Local Group Galaxies and Large Scale Structure behind the Galactic Bulge
Rosa A. Gonzalez, Benne Holwerda, Laurent Loinard +2
Recently, we have developed and calibrated the Synthetic Field Method to derive total extinction through disk galaxies. The method is based on the number counts and colors of dista…
Cooper Pairing Revisited
V. C. Aguilera-Navarro, M. Fortes, M. de Llano +1
We recall the fundamental fact that Cooper pairs defined without ignoring two- hole pairs along with two-particle ones leads to a purely imaginary pair energy when the problem is b…
Can Hydrostatic Cores Form Within Isothermal Molecular Clouds?
Enrique Vazquez-Semadeni, Mohsen Shadmehri, Javier Ballesteros-Paredes
Under the assumptions that molecular clouds are nearly spatially and temporally isothermal and that the density peaks (``cores'') within them are formed by turbulent fluctuations,…
