High redshift FRII radio galaxies: X-ray properties of the cores
E. Belsole, D. M. Worrall, M. J. Hardcastle
We present an extensive X-ray spectral analysis of the cores of 19 FRII sources in the redshift range 0.5<z<1.0 which were selected to be matched in isotropic radio power. The samp…
A data-driven Bayesian approach for finding young stellar populations in early-type galaxies from their UV-optical spectra
L. A. Nolan, M. O. Harva, A Kaban +1
We present the results of a novel application of Bayesian modelling techniques, which, although purely data driven, have a physically interpretable result, and will be useful as an…
The XMM-Newton Slew Survey: towards the XMMSL1 catalogue
M. P. Esquej, B. Altieri, D. Bermejo +4
The XMM-Newton satellite is the most sensitive X-ray observatory flown to date due to the great collecting area of its mirrors coupled with the high quantum efficiency of the EPIC…
INTEGRAL high energy behaviour of 4U 1812-12
A. Tarana, A. Bazzano, P. Ubertini +5
The low mass X-ray binary system 4U 1812-12 was monitored with the INTEGRAL observatory in the period 2003-2004 and with BeppoSAX on April 20, 2000. We report here on the spectral…
Extended sources in the XMM-Newton slew survey
V. Lazaro, R. Saxton, A. M. Read +4
The low background, good spatial resolution and great sensitivity of the EPIC-pn camera on XMM-Newton give useful limits for the detection of extended sources even during the short…
HADRON05 Summary: Heavy Quark Hadrons and Theory
T. Barnes
This HADRON05 summary covers the topics of (1) mesons containing heavy quarks, and (2) theory. The new material discussed here is taken mainly from plenary presentations. We specif…
Fast neutral outflows in powerful radio galaxies: a major source of feedback in massive galaxies
R. Morganti, C. N. Tadhunter, T. A. Oosterloo
We report the detection of fast (~ 1000 km/s), massive outflows of neutral gas observed -- using the WSRT -- as 21-cm HI absorption against the strong radio continuum of seven radi…
2D Ferromagnetism in the High-Tc Analogue Cs_2AgF_4
S. E. McLain, D. A. Tennant, J. F. C. Turner +5
Although the precise mechanism of high-Tc superconductivity in the layered cuprates remains unknown, it is generally thought that strong 2D Heisenberg antiferromagnetism combined w…
The Secular Evolution of Disk Structural Parameters
Victor P. Debattista, Lucio Mayer, C. Marcella Carollo +3
We present a comprehensive series of -body as well as -body + SPH simulations to study the secular evolution of the structure of disk galaxies. Our simulations are organized…
A further 'degree of freedom' in the rotational evolution of stars
V. Holzwarth, M. Jardine
Observational and theoretical investigations provide evidence for non-uniform spot and magnetic flux distributions on rapidly rotating stars, which have a significant impact on the…
Controlling the collimation and rotation of hydromagnetic disk winds
Ralph E. Pudritz, Conrad Rogers, Rachid Ouyed
(Abriged) We present a comprehensive set of axisymmetric, time-dependent simulations of jets from Keplerian disks whose mass loading as a function of disk radius is systematically…
The kinetic temperature of a molecular cloud at redshift 0.7: Ammonia in the gravitational lens B0218+357
C. Henkel, N. Jethava, A. Kraus +6
Using the Effelsberg 100-m telescope, absorption in the (J,K) = (1,1), (2,2) and (3,3) inversion lines of ammonia (NH_3) was detected at a redshift of z = 0.6847 toward the gravita…
PHASES High Precision Differential Astrometry of delta Equulei
Matthew W. Muterspaugh, Benjamin F. Lane, Maciej Konacki +4
delta Equulei is among the most well-studied nearby binary star systems. Results of its observation have been applied to a wide range of fundamental studies of binary systems and s…
Chaotic Dynamics of a Free Particle Interacting Linearly with a Harmonic Oscillator
Stephan De Bievre, Paul E. Parris, Alex A. Silvius
We study the closed Hamiltonian dynamics of a free particle moving on a ring, over one section of which it interacts linearly with a single harmonic oscillator. On the basis of num…
A Spitzer/IRAC Survey of the Orion Molecular Clouds
S. T. Megeath, K. M. Flaherty, J. Hora +9
We present initial results from a survey of the Orion A and B molecular clouds made with the InfraRed Array Camera (IRAC) onboard the Spitzer Space Telescope. This survey encompass…
Charmonium production in p pbar annihilation: Estimating cross sections from decay widths
A. Lundborg, T. Barnes, U. Wiedner
The cross sections for the charmonium production processes p pbar -> m Psi, where m is a light meson and Psi is a charmonium state, are of great interest for the planned p-pbar exp…
"PAH" emission bands in selected planetary nebulae: a study of the behaviour with gas phase C/O ratio
Martin Cohen, Michael J. Barlow
Airborne and space-based low-resolution spectroscopy in the 1980s discovered tantalizing quantitative relationships between the gas phase C/O abundance ratio in planetary nebulae (…

We present an analysis of the Far Ultraviolet Spectroscopic Explorer (FUSE) spectrum of HD141569A, a transitional object known to possess a circumstellar disk. We observe two compo…
Can a photometric redshift code reliably determine dust extinction?
T. S. R Babbedge, R. Whitaker, S. Morris
Photometric redshifts can be routinely obtained to accuracies of better than 0.1 in Delta(z)/(1+z). However, the issue of dust extinction is one that has still not been well quanti…
