We derive the galaxy luminosity functions in V-, R-, I-, and K-bands of the cluster EIS 0048 at z ∼ 0.64 from data taken at the ESO Very Large Telescope. The data span the restframe wavelength range from UV, which is sensitive to even low rates of star formation, to the NIR, which maps the bulk of the stellar mass. By comparison of our data and of previous results with pure luminosity evolution...

We present follow-up observations of pulsating subdwarf B (sdB) stars as part of our efforts to resolve the pulsation spectra for use in asteroseismological analyses. This paper reports on multisite campaigns of the pulsating sdB stars PG 1618+563B and PG 0048+091. Data were obtained from observatories placed around the globe for coverage from all longitudes. For PG 1618+563B, our five-site cam...

An increase of the NLC repetition rate from 120 Hz to 180 Hz while keeping other interaction point parameters unchanged will require changes in the design of the damping rings to provide an increased damping rate. In this note, we describe an initial lattice design for a ring that provides the required damping at 90 Hz. Two such rings, operated in series or in parallel, would provide the requir...

Multiplicative preconditioning is a popular SVD-based techniques for the solution of linear systems of equations, but our SVD-free additive preconditioners are more readily available and better preserve matrix structure. We combine additive preconditioning with aggregation and other relevant techniques to facilitate the solution of linear systems of equations and some other fundamental matrix c...
