Maximum-Likelihood Comparisons of Tully-Fisher and Redshift Data: Constraints on Omega and Biasing

Jeffrey A. Willick, Michael A. Strauss, Avishai Dekel +1

We compare Tully-Fisher (TF) data for 838 galaxies within cz=3000 km/sec from the Mark III catalog to the peculiar velocity and density fields predicted from the 1.2 Jy IRAS redshi…

Tilted Hybrid Inflation

Juan Garcia-Bellido, Andrei Linde

We propose a new version of the hybrid inflation scenario that produces a significantly tilted n>1 spectrum of curvature perturbations. This may happen in supersymmetric models whe…

Sensitivity of Gamma-Ray Detectors to Polarization

I. -A. Yadigaroglu

Previous studies have shown that the largest gamma-ray detector to date, EGRET, does not have useful polarization sensitivity. We have explored here some improved approaches to ana…

A spectral study of gamma-ray emitting AGN

Martin Pohl

In this paper I investigate the -ray spectra of AGN by summing up the intensity and the power-law fit statistic of Quasars and OVV's and BL Lac's separately. The spectrum of the…

Nongaussian Isocurvature Perturbations from Inflation

A. Linde, V. Mukhanov

We present a class of very simple inflationary models of two scalar fields which leads to nongaussian isothermal perturbations with "blue" spectrum, n > 1. One of the models is ins…

Gamma-Ray Pulsars and Massive Stars in the Solar Neighborhood

I. -A. Yadigaroglu, Roger W. Romani

We revisit the association of unidentified Galactic plane EGRET sources with tracers of recent massive star formation and death. Up-to-date catalogs of OB associations, SNRs, young…
