Bar evolution over the last 8 billion years: A constant fraction of strong bars in th GEMS Survey
(2004-11)
One-third of present-day spirals host optically visible strong bars that drive their dynamical evolution. However, the fundamental question of how bars evolve over cosmological times has yet to be resolved, and even the ...
An all-sky optical catalogue of radio/X-ray sources
(2004-11)
We present an all-sky catalogue that aligns and overlays the ROSAT HRI, RASS, PSPC and WGA X-ray catalogues and the NVSS, FIRST and SUMSS radio catalogues onto the optical APM and USNO-A catalogues. Objects presented are ...
A 1200-micron MAMBO survey of ELAISN2 and the Lockman Hole - I. Maps, sources and number counts
(2004-11)
We present a deep, new 1200μm survey of the ELAISN2 and Lockman Hole fields using the Max Planck Millimeter Bolometer array (MAMBO). The areas surveyed are 160 arcmin2 in ELAISN2 and 197 arcmin2 in the Lockman Hole, covering ...
Novel role for P2X receptor activation in endothelium-dependent vasodilation
(2004-11-01)
ATP is an important vasoactive mediator, which acts via two receptor classes: P2X and P2Y. Activation of P2X receptors has traditionally been associated with the well-characterised vasoconstrictor properties of ATP. In the ...
Time-energy relation of the n_TOF neutron beam : energy standards revisited
(2004-10-21)
The accurate determination of neutron cross-sections as a function of the neutron energy at a time-of-flight facility requires a precise knowledge of the time-energy relation for the neutron beam. For the n-TOF neutron ...
Neutron capture cross section measurement of Sm-151 at the CERN neutron time of flight facility (n_TOF)
(2004-10-15)
The Sm-151(n,gamma)Sm-152 cross section has been measured at the spallation neutron facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The new facility combines excellent resolution in neutron time-of-flight, ...
Submillimetre constraints on hyper-extremely red objects in the Subaru Deep Field
(2004-10-11)
We have mapped the submillimetre wavelength continuum emission from the Subaru Deep Field (SDF) at 450 and 850 μm with the Submillimetre Common-User Bolometer Array (SCUBA) detector on the James Clerk Maxwell Telescope. ...
Veterinary anthelmintics : old and new
(2004-10)
Between 1960 and 1980, extraordinary success was achieved in anthelmintic development for animals. In these 20 years, drugs with diverse structure, novel activity and enviable safety were produced for a global livestock ...
