A VLBI Search for the Origin of Wobbling in Blazar Jets
I. Agudo
An increasing number of blazars have been reported to show jet wobbling (i.e., non-regular rotations of the structural position angle of their innermost jets in the plane of the sk…
Close-up of primary and secondary asteroseismic CoRoT targets and the ground-based follow-up observations
K. Uytterhoeven, E. Poretti, M. Rainer +13
To optimise the science results of the asteroseismic part of the CoRoT satellite mission a complementary simultaneous ground-based observational campaign is organised for selected…
Effects of dust scattering albedo and 2175 A bump on ultraviolet colours of normal disc galaxies
Akio K. Inoue, Veronique Buat, Denis Burgarella +3
We discuss dust properties in the interstellar medium (ISM) of nearby normal galaxies, by comparing observations in the ultraviolet (UV) with simulations by a radiative transfer mo…
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…
Internal Kinematics of Microstructures and Implications
Luis F. Miranda
High resolution images at different wavelengths show the common presence of structures and microstructures in planetary nebulae (PNe), which are not well incorporated to the existi…
Photometry of Be Stars in the vicinity of COROT primary targets for asteroseismology
J. Gutierrez-Soto, J. Fabregat, J. Suso +3
We present differential photometry of Be stars close to potential COROT primary targets for asteroseismology. Several stars are found to be short period variables. We propose them…
Analysis of Balmer Profiles of early type stars
Mercedes Molla, Angeles I. Diaz, Mar Alvarez Alvarez +1
The spectral energy distribution (SED) of recent star formation regions is dominated by the more massive and early stars (O and B types). These stars show large and very significan…
WNB 0313+683: Analysis of a Newly Discovered Giant Radio Galaxy
A. P. Schoenmakers, K. -H. Mack, L. Lara +4
We present the results of a detailed analysis of the newly discovered 15 arcmin large FRII-type radio galaxy WNB 0313+683. It has a redshift of 0.0901 +/- 0.0002 and a projected li…
