The nature of the magnetic belt in M 31
The most conspicuous feature of the large-scale magnetic field in the Andromeda nebula (M31) is a magnetic belt centred at a galacto-centric radius of about 10 kpc. We suggest a nonlinear dynamo model for M31, which associates this belt with the gas density profile as well as with the kinematic parameters of M31. Our model is based on the observed density profile and vertical structure of the g...
متن کاملOn the nature of the extragalactic number counts in the K - band
Context. The galaxy number counts has been traditionally used to test models of galaxy evolution. However, the origin of significant differences in the shape of number counts at different wavelengths is still unclear. By relating the most remarkable features in the number counts with the underlying galaxy population it is possible to introduce further constraints on galaxy evolution. Aims. We a...
متن کاملLobe Advance Velocities in the Extragalactic Compact Symmetric Object 4 C 31 . 04
We report on the results of a two epoch study of the low power Compact Symmetric Object 4C 31.04. Observations performed with the VLBA at 5 GHz in 1995 and 2000 have yielded images of this source at milliarcsecond angular resolution. A central core is detected, with bright compact hot spots and extended lobes on both sides. Model-fitting and other analysis of the data (brightness profile, diffe...
متن کاملThe Extragalactic Nature of the Serendipitous Bepposax Source 2masx J14585116−1652223 ⋆
As a follow-up of the X–ray serendipitous detection of the source 2MASX J14585116−1652223, medium-resolution optical spectroscopic observations collected at the 1.5-metre “Cassini” telescope of the Astronomical Observatory of Bologna were performed. This allowed us to determine the extragalactic nature of this X–ray source, which is a Type 2 Seyfert galaxy at redshift z = 0.068 ± 0.001. This re...
متن کاملThe Nature and Structure of Ethical Papers
Nowadays, because of their innovative and scholarly nature, the scientific-research articles are taken into account as the best and sometimes the only judging criterion of their authors and scientific community. Therefore, all those who work in the academic fields and are working as A.M. and doctorate students or teachers are required to test their proficiency and to show that they are qualifie...
