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…
On an Analytical Framework for Voids: Their abundances, density profiles and local mass functions
Santiago G. Patiri, Juan E. Betancort-Rijo, Francisco Prada
We present a general analytical procedure for computing the number density of voids with radius above a given value within the context of gravitational formation of the large scale…
Chemical abundances in spiral and irregular galaxies. O and N abundances derived from global emission--line spectra
L. S. Pilyugin, T. Contini, J. M. Vilchez
The validity of oxygen and nitrogen abundances derived from the global emission-line spectra of galaxies via the P-method has been investigated using a collection of published spec…
