Constitutional developments since the Lisbon Treaty in the area of freedom, security and justice at supranational and national level

In order to evaluate the constitutional developments in the area of freedom, security and justice (AFSJ) of the Lisbon Treaty, this article begins with a tour d'horizon of the new provisions in the field of AFSJ. Their impact on the supranational and national constitutional legal order is discussed, and the differnces with the Treaty of Nice. There is also a review of some European Court of Justice cases interpreting the old Third Pillar instrument and comparing them with the new Lisbon challenges.

7.960 MC/S Observations of Radio Sources in the Sydney Catalogue

During March and September 1960, observations were made with the Caltech interferometer of 739 sources listed in the two catalogues of Mills, Slee and Hill^1,^2. The primary purpose of the investigation was to provide this observatory with a 960 Mc/s "finding list" for future measurements of source sizes and precise positions. The area covered in these observations was: 0: -50° to -20° a: 17 to 5 hours o: -20° to +10° a: O to 24 hours. In general, the observations were restricted to sources in the MSH catalogues whose flux density at 86 Mc/s was greater than 15 x l0^(-26) watts m^-2 (c/s)^-l. All sources down to this level were examined with the exception of those in the region 18h to 24h, between o^o and -10° . Most sources were observed near transit for at least four or five minutes at the position given in the Sydney catalogues. This allowed us to observe one 10-degree declination zone each night. The flux density of each source was measured relative to the standard source Hydra A ( 09-14), which was observed each night when possible. When Hydra A was not available, 22-11 was used as a secondary calibrator. All observations were made at night to avoid effects of solar radiation

MOJAVE: Monitoring of Jets in AGN with VLBA Experiments. VII. Blazar Jet Acceleration

We discuss acceleration measurements for a large sample of extragalactic radio jets from the MOJAVE program which studies the parsec-scale jet structure and kinematics of a complete, flux-density-limited sample of Active Galactic Nuclei (AGN). Accelerations are measured from the apparent motion of individual jet features or "components" which may represent patterns in the jet flow. We find that significant accelerations are common both parallel and perpendicular to the observed component velocities. Parallel accelerations, representing changes in apparent speed, are generally larger than perpendicular acceleration that represent changes in apparent direction. The trend for larger parallel accelerations indicates that a significant fraction of these changes in apparent speed are due to changes in intrinsic speed of the component rather than changes in direction to the line of sight. We find an overall tendency for components with increasing apparent speed to be closer to the base of their jets than components with decreasing apparent speed. This suggests a link between the observed pattern motions and the underlying flow which, in some cases, may increase in speed close to the base and decrease in speed further out; however, common hydro-dynamical processes for propagating shocks may also play a role. About half of the components show "non-radial" motion, or a misalignment between the component's structural position angle and its velocity direction, and these misalignments generally better align the component motion with the downstream emission. Perpendicular accelerations are closely linked with non-radial motion. When observed together, perpendicular accelerations are usually in the correct direction to have caused the observed misalignment.Comment: 17 pages, 11 figures, 1 table, accepted by the Astrophysical Journa

The micro-Jy Radio Source Population: the VLA-CDFS View

We analyse the 267 radio sources from our deep (flux limit of 42 microJy at the field center at 1.4 GHz) Chandra Deep Field South 1.4 and 5 GHz VLA survey. The radio population is studied by using a wealth of multi-wavelength information, including morphology and spectral types, in the radio, optical, and X-ray bands. The availability of redshifts for ~ 70% of our sources allows us to derive reliable luminosity estimates for the majority of the objects. Contrary to some previous results, we find that star-forming galaxies make up only a minority (~ 1/3) of sub-mJy sources, the bulk of which are faint radio galaxies, mostly of the Fanaroff-Riley I type.Comment: 6 pages, 3 figures, to appear in the proceedings of "At the Edge of the Universe", Sintra, Portugal, Oct. 9 - 13, 200
