A detailed study of the nuclear region of Mrk 273
M. Bondi, D. Dallacasa, M. A. Peerez Torres +1
We present 5 GHz EVN+MERLIN observations of the nuclear region of the ultra luminous infrared galaxy Mrk 273. These observations confirms the detection, on the mas scale, of two re…
Multi-wavelength differential astrometry of the S5 polar cap sample
J. C. Guirado, J. M. Marcaide, E. Ros +2
We report on the status of our S5 polar cap astrometry program. Since 1997 we have observed all the 13 radio sources of the complete S5 polar cap sample at the wavelengths of 3.6 c…
Classical nova explosions
Margarita Hernanz
A review of the present status of nova modeling is made, with a special emphasis on some specific aspects. What are the main nucleosynthetic products of the explosion and how do th…
Security problems with a chaos-based deniable authentication scheme
G. Alvarez
Recently, a new scheme was proposed for deniable authentication. Its main originality lied on applying a chaos-based encryption-hash parallel algorithm and the semi-group property…
Many body effects on - axis properties: out of plane coherence and bilayer splitting
F. Guinea, M. P. Lopez-Sancho, M. A. H. Vozmediano
The out-of-plane hopping in layered metals with strong electronic correlation is analyzed theoretically. By studying the effects of in-plane interactions on the interlayer tunnelli…
On the geometry of moduli spaces of coherent systems on algebraic curves
S. Bradlow, O. Garcia-Prada, V. Mercat +2
Let be an algebraic curve of genus . A coherent system on consists of a pair , where is an algebraic vector bundle over of rank and degree and …
