Importance of an Astrophysical Perspective for Textbook Relativity
Eric G. Blackman
The importance of a teaching a clear definition of the ``observer'' in special relativity is highlighted using a simple astrophysical example from the exciting current research are…
Mechanisms for High-frequency QPOs in Neutron Star and Black Hole Binaries
Lev Titarchuk, Iosif Lapidus, Alex Muslimov
We explain the millisecond variability detected by Rossi X-ray Timing Explorer (RXTE) in the X-ray emission from a number of low mass X-ray binary systems (Sco X-1, 4U1728-34, 4U16…
The Topology of the IRAS Point Source Catalogue Redshift Survey
A. Canavezes, V. Springel, S. J. Oliver +10
We investigate the topology of the new Point Source Catalogue Redshift Survey (PSCz) of IRAS galaxies by means of the genus statistic. The survey maps the local Universe with appro…
Quantum Integrability of Coupled N=1 Super Sine/Sinh-Gordon Theories and the Lie Superalgebra D(2,1;\A)
Jonathan M. Evans, Jens Ole Madsen
We discuss certain integrable quantum field theories in (1+1)-dimensions consisting of coupled sine/sinh-Gordon theories with N=1 supersymmetry, positive kinetic energy, and bosoni…
The decay of optical emission from the Gamma-Ray Burst GRB 970228
Titus J. Galama, Paul J. Groot, Jan van Paradijs +6
We present the R_c band light curve of the optical transient (OT) associated with GRB970228, based on re-evaluation of existing photometry. Data obtained until April 1997 suggested…
Connections between M-theory and superstrings
Michael B. Green
This article reviews the non-perturbative structure of certain higher derivative terms in the type II string theory effective action and their connection to one-loop effects in ele…
Refreshed Shocks and Afterglow Longevity in GRB
M. J. Rees, P. Meszaros
We consider fireball models where the ejecta have a range of bulk Lorentz factors, so that the inner (lower ) parts may carry most of the mass, or even most of the energy. The o…
Nonequilibrium relaxation of the two-dimensional Ising model: Series-expansion and Monte Carlo studies
Jian-Sheng Wang, Chee Kwan Gan
We study the critical relaxation of the two-dimensional Ising model from a fully ordered configuration by series expansion in time t and by Monte Carlo simulation. Both the magneti…
Systematic behaviour of the in-plane penetration depth in d-wave cuprates
C. Panagopoulos, J. R. Cooper, T. Xiang
We report the temperature T and oxygen concentration dependences of the penetration depth of grain-aligned YBa_2Cu_3O_{7-δ} with δ= 0.0, 0.3 and 0.43. The values of the in-plane λ_…
Discovery of a Supernova Explosion at Half the Age of the Universe and its Cosmological Implications
S. Perlmutter, G. Aldering, M. Della Valle +20
The ultimate fate of the universe, infinite expansion or a big crunch, can be determined by measuring the redshifts, apparent brightnesses, and intrinsic luminosities of very dista…
Gamma Ray Bursts from Baryon Decay in Neutron Stars
Ue-Li Pen, Abraham Loeb, Neil Turok
The standard unbroken electroweak theory is known to erase baryon number. The baryon number symmetry can be restored in the core of a neutron star as its density diverges via gravi…
Dynamic D8-branes in IIA string theory
A. Chamblin, M. J. Perry
In this paper we perform a detailed investigation of the Dirichlet eight-brane of the Type IIA string theory, when the effects of gravity are included. In particular, consider what…
On the Form of the HII Region Luminosity Function
M. S. Oey, C. J. Clarke
Observed variations in the HII region luminosity function (HII LF) seen in spiral arm vs. interarm regions, and different galactic Hubble type, can be explained simply by evolution…
On the difficulty of launching an outflow from an accretion disk
Gordon I. Ogilvie, Mario Livio
We solve for the local vertical structure of a thin accretion disk threaded by a poloidal magnetic field. The angular velocity deviates from the Keplerian value as a result of the…
Persistence Amplitudes from Numerical Quantum Gravity
Peter D'Eath, Andrew Sornborger
The Euclidean quantum amplitude to go between data specified on an initial and a final hypersurface may be approximated by the tree amplitude exp(-I_{classical}/\hbar), where I_{cl…
Forced kink of mode
Ya. M. Shnir
The motion of a one-dimensional kink and its energy losses are considered as a model of interaction of nontrivial topological field configurations with external fields.
Bulk charges in eleven dimensions
S. W. Hawking, M. M. Taylor-Robinson
Eleven dimensional supergravity has electric type currents arising from the Chern-Simon and anomaly terms in the action. However the bulk charge integrates to zero for asymptotical…
Hubble Space Telescope imaging of the CFRS and LDSS redshift surveys II: Structural parameter and the evolution of disk galaxies to z=1
S. J. Lilly, D. Schade, R. S. Ellis +10
(Abridged) Several aspects of the evolution of star-forming galaxies are studied using measures of the 2-dimensional surface brightness profile of a sample of 341 faint objects sel…
HST imaging of CFRS and LDSS galaxies - I: Morphological Properties
J. Brinchmann, R. Abraham, D. Schade +9
(Abridged) We analyse Hubble Space Telescope images of a complete sample of 341 galaxies drawn from both the Canada France and Autofib/Low Dispersion Survey Spectrograph ground-bas…
Renormalon Phenomena in Jets and Hard Processes
B. R. Webber
The `renormalon' or `dispersive' method for estimating non-perturbative corrections to QCD observables is reviewed. The corrections are power-suppressed, i.e. of the form w…
Torons and black hole entropy
Miguel S. Costa, Malcolm J. Perry
We consider a supersymmetric system of D-5-branes compactified on a 5-torus with a self-dual background field strength on a 4-torus and carrying left-moving momentum along a circle…
(8,0) Quantum mechanics and symmetry enhancement in type I' superstrings
Constantin P. Bachas, Michael B. Green, Adam Schwimmer
The low-energy supersymmetric quantum mechanics describing D-particles in the background of D8-branes and orientifold planes is analyzed in detail, including a careful discussion o…
An approach to F-theory
S. F. Hewson
We consider BPS configurations in theories with two timelike directions from the perspective of the supersymmetry algebra. We show that whereas a BPS state in a theory with one tim…
M-theory from its superalgebra
P. K. Townsend
These lectures explore what can be learnt about M-theory from its superalgebra. The first three lectures introduce the 'basic' branes of M-theory, and type II superstring theories,…
