A First Close Look at the Balmer-edge Behavior of the Quasar Big Blue Bump

Makoto Kishimoto, Robert Antonucci, Omer Blaes

We have found for the first time a Balmer edge feature in the Big Blue Bump emission of a quasar. The feature is seen in the polarized flux spectrum of the quasar, where all the em…

Inflationary cosmology, a dissipative quantum field theory process

Arjun Berera

The current status of early universe cosmology can be summarized as precision, but inherently limited, data requiring explanation from precision and robust theory. Specifically inf…

Two-band second moment model and an interatomic potential for caesium

Graeme J. Ackland, Stewart K. Reed

A semi-empirical formalism is presented for deriving interatomic potentials for materials such as caesium or cerium which exhibit volume collapse phase transitions. It is based on…

The interaction energy of well-separated Skyrme solitons

N. S. Manton, B. J. Schroers, M. A. Singer

We prove that the asymptotic field of a Skyrme soliton of any degree has a non-trivial multipole expansion. It follows that every Skyrme soliton has a well-defined leading multipol…

Top Pair Production Beyond Double-Pole Approximation: pp, pp~ --> 6 Fermions and 0, 1 or 2 Additional Partons

N. Kauer

Hadron collider cross sections for tt~ production and di-lepton, single-lepton and all-jet decays with up to 2 additional jets are calculated using complete LO matrix elements with…

Measurement of Inclusive Spin Structure Functions of the Deuteron

J. Yun, S. E. Kuhn, G. E. Dodge +2

We report the results of a new measurement of spin structure functions of the deuteron in the region of moderate momentum transfer ( = 0.27 -- 1.3 (GeV/c)) and final hadro…

Adhesion between a viscoelastic material and a solid surface

F. Saulnier, T. Ondarcuhu, A. Aradian +1

In this paper, we present a qualitative analysis of the dissipative processes during the failure of the interface between a viscoelastic polymer and a solid surface. We reassess th…

Shear and magnification angular power spectra and higher-order moments from weak gravitational lensing

Andrew J. Barber, A. N. Taylor

We present new results on the gravitational lensing shear and magnification power spectra obtained from numerical simulations of a flat cosmology with a cosmological constant. Thes…

The 2dF Galaxy Redshift Survey: correlation functions, peculiar velocities and the matter density of the Universe

E. Hawkins, S. Maddox, S. Cole +27

We present a detailed analysis of the two-point correlation function, from the 2dF Galaxy Redshift Survey (2dFGRS). We estimate the redshift-space correlation function, xi(s), from…

The clustering of halo mergers

Will J. Percival, Douglas Scott, John A. Peacock +1

We analyse the spatial distribution of halo merger sites using four numerical simulations with high time resolution of structure growth in a Lambda-CDM cosmology. We find no eviden…

The Single-Particle Structure of Neutron-Rich Nuclei of Astrophysical Interest at the Ornl Hribf

D. W. Bardayan, J. C. Batchelder, J. C. Blackmon +19

The rapid nuetron-capture process (r process) produces roughly half of the elements heavier than iron. The path and abundances produced are uncertain, however, because of the lack…
