Observation of contemporaneous optical radiation from a gamma-ray burst
(Macmillan Magazines Ltd., 1999-04-01)
The origin of gamma-ray bursts (GRBs) has been enigmatic since their discovery(1). The situation improved dramatically in 1997, when the rapid availability of precise coordinates(2,3) for the bursts allowed the detection ...
Formation and Evolution of X-Ray-Clusters - A Hydrodynamic Simulation of the Intracluster Medium

Expectations for X-Ray-Cluster Observations by the Rosat Satellite
(Univ Chicago Press, 1991-12-10)
We present predictions for characteristics of the X-ray cluster population expected to be observed by the ROSAT satellite. The theoretical modeling requires an assumed fluctuation spectrum and relations describing the ...
Properties of the intracluster medium in an ensemble of nearby galaxy clusters
(Univ Chicago Press, 1999-06-01)
We present a systematic analysis of the intracluster medium (ICM) in an X-ray flux limited sample of 45 galaxy clusters. Using archival ROSAT Position-Sensitive Proportional Counter (PSPC) data and published ICM temperatures, ...
Asymmetries in limb darkening reanalyzed
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-03)
The cause of the asymmetries in limb darkening reported by Neckel and Labs (1987) is discussed on the basis of new, stray-light-free observations, and found to be of instrumental origin.
2-Fluid Simulations of Galaxy Formation
(Univ Chicago Press, 1994-02-10)
We investigate the formation of galaxies and larger structure with a simulation modeling two gravitationally coupled fluids representing dark matter and baryons. The baryon gas dynamics are calculated with a smoothed ...
Snare-assisted vascular access: A new technique
(John Wiley & Sons, Inc., 1999-07)
Access to the central circulation can be difficult in small infants, particularly when normal anatomic landmarks have been altered. We describe a new technique that utilizes any existing central catheter to establish ...
