When angular objects in lensing are considered as linear objects, interesting phenomena start happening. Tachyonic caustics are one example. We
Planetary transits of bright stars, V < 10, offer the best opportunity for detailed studies of extra-solar planets, such as
We construct four dimensional gauge theories in which the successful supersymmetric unification of gauge couplings is preserved but accelerated by
Compact binaries have long been a paradigm for accretion theory. Much of our present view of how accretion occurs comes
Cosmic microwave anisotropy satellites promise extremely accurate measures of the amplitude of perturbations in the universe. We use a numerical
Dense ($n=4 \times 10^{11}$ cm$^{-2}$) arrays of Ge quantum dots in Si host were studied using attenuation of surface acoustic
Using atomistic pseudopotential wave functions we calculate the electron and hole charging energies of InAs quantum dots. We find that
The Kodama State for Lorentzian gravity presupposes a particular value for the Immirzi-parameter, namely $β=-i$. However, the derivation of black
The dwarf spheroidal galaxies (dSphs) in the Local Group are excellent systems on which we can test theories of galaxy
The Planck Surveyor cosmic microwave background (CMB) imaging mission will make very sensitive maps of the whole sky at microwave,
We describe a distributed processing cluster of inexpensive Linux machines developed jointly by the Astronomy and Computer Science departments at
A recent preprint by Yan & Windhorst (astro-ph/0407493) independently repeats our selection of candidate z~6 galaxies in the Hubble Ultra
A new measurement of $R_b$ with the ALEPH detector at LEP using five mutually exclusive hemisphere tags is presented. The
In this paper we study empirically the Forward Rate Curve (FRC) of 5 different currencies. We confirm and extend the
We report a simple one pot process for the preparation of lead sulphide (PbS) nanocrystals in the conjugated polymer MEH-PPV,
We consider an alternative to the standard picture of CV and LMXB evolution, namely the idea that most CVs (and
Depending on the outcome of pre-CV formation, mass transfer may set in under thermally unstable conditions in a significant number
We consider families of theories with large N=4 superconformal symmetry. We define an index generalizing the elliptic genus of theories
We report spectroscopic and interferometric observations of the moderately metal-poor double-lined binary system HD 195987, with an orbital period of
An introductory account is given of the inflationary cosmology, which postulates a period of accelerated expansion during the Universe's earliest
We solve a coarsening system with small but arbitrary anisotropic surface tension and interface mobility. The resulting size-dependent growth shapes
Using media with extremely low group velocities one can create an optical analog of a curved space-time. Leonhardt and Piwnicki
The accurate simulation of collapsed objects requires that a huge range of spatial scales be well resolved if the result
This paper describes a serendipitous galaxy cluster survey that we plan to conduct with the XMM X-ray satellite. We have
