Over the past three years, our confidence in the inferred values of cosmological parameters has increased dramatically, confirming that the flat matter dominated Universe that dominated cosmological model building for the past 20 years does not correspond to the Universe in which we live. I review recent developments here and quote best fit current values for fundamental cosmological parameters.

We present current results of an ongoing survey for OH megamasers in luminous infrared galaxies at the Arecibo Observatory. The survey is now two-thirds complete, and has resulted in the discovery of 35 new OH megamasers at z > 0.1, 24 of which are presented in this paper. We discuss the properties of each source in detail, including an exhaustive survey of the literature. We also place upper l...

We investigate the development of electromagnetic cascades in ice using a GEANT Monte Carlo simulation. We examine the Cherenkov pulse that is generated by the charge excess that develops and propagates with the shower. This study is important for the RICE experiment at the South Pole, as well as any test beam experiment which seeks to measure coherent Cherenkov radiation from an electromagneti...

The local interstellar spectrum of cosmic ray electrons is derived by correcting the data from balloon and space measurements for the solar modulation effect. The resulting spectrum, after the renormalization of some experimental data set, can be fitted with a single power law from about 3 GeV to 2 TeV with spectral index γ = 3.42± 0.02. On the other hand, at low energies the measurements by CA...
