The Weak Blue Bump of H2106-099 and AGN De-Reddening
B. Grossan, R. A. Remillard, H. V. Bradt +3
We present multi-frequency spectra of the Seyfert 1 galaxy H2106-099, from radio to hard X-rays, spanning over a decade of observations. The hard X-ray (2-20 keV) spectrum measured…
Optical/Near-Infrared Observations of GRO J1744-28
D. M. Cole, D. E. Vanden Berk, S. A. Severson +8
We present results from a series of optical (g and r-band) and near-infrared (K'-band) observations of the region of the sky including the entire XTE and ROSAT error circles for th…
First Results from the All-Sky Monitor on the Rossi X-ray Timing Explorer
Alan M. Levine, Hale Bradt, Wei Cui +5
The All-Sky Monitor on the Rossi X-ray Timing Explorer has been monitoring the sky in the 1.5 - 12 keV band since late February. The instrument consists of three coded-aperture cam…
Measurements of the Cosmological Parameters Omega and Lambda from the First 7 Supernovae at z >= 0.35
S. Perlmutter, S. Gabi, G. Goldhaber +21
We have developed a technique to systematically discover and study high-redshift supernovae that can be used to measure the cosmological parameters. We report here results based on…
Limits on Far-UV Emission from Warm Gas in Clusters of Galaxies with the Hopkins Ultraviolet Telescope
W. Van Dyke Dixon, Mark Hurwitz, Henry C. Ferguson
We have searched the far-UV spectra of five clusters of galaxies observed with the Hopkins Ultraviolet Telescope (HUT) for emission in the resonance lines of O VI (1032,1038 A) and…
Infrared to Ultraviolet Wavelength-Dependent Variations Within the Pulse Profile Peaks of the Crab Nebula Pulsar
S. S. Eikenberry, G. G. Fazio, S. M. Ransom +3
We present evidence of wavelength-dependent variations within the infrared, optical, and ultraviolet pulse profile peaks of the Crab Nebula pulsar. The leading and trailing edge ha…
The Type Ia Supernova Rate at z
R. Pain, I. M. Hook, S. Deustua +17
We present the first measurement of the rate of Type Ia supernovae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project. Three…
Rapid follow-up ROSAT observation of GRB 940301
J. Greiner, N. Bade, K. Hurley +2
The strong GRB of March 1, 1994 was imaged by COMPTEL and found to have an identical location within the errors as a burst which occurred on July 4, 1993. This location coincidence…
TGRS Observation of the Galactic Center Annihilation Line
B. J. Teegarden, T. L. Cline, N. Gehrels +8
The TGRS (Transient Gamma-Ray Spectrometer) experiment is a high-resolution germanium detector launched on the WIND satellite on Nov. 1, 1994. Although primarily intended to study…
4-Year COBE DMR Cosmic Microwave Background Observations: Maps and Basic Results
C. L. Bennett, A. Banday, K. M. Gorski +7
The cosmic microwave background radiation provides unique constraints on cosmological models. In this Letter we present a summary of the spatial properties of the cosmic microwave…
RMS Anisotropy in the COBE-DMR Four-Year Sky Maps
A. J. Banday, K. M. Gorski, C. L. Bennett +5
The sky-RMS is the simplest model-independent characterization of a cosmological anisotropy signal. The RMS temperature fluctuations determined from the -DMR four-year sky ma…
Power Spectrum of Primordial Inhomogeneity Determined from the 4-Year COBE DMR Sky Maps
K. M. Gorski, A. J. Banday, C. L. Bennett +4
Fourier analysis and power spectrum estimation of the cosmic microwave background anisotropy on an incompletely sampled sky developed by Gorski (1994) has been applied to the high-…
Tests for Non-Gaussian Statistics in the DMR Four-Year Sky Maps
A. Kogut, A. J. Banday, C. L. Bennett +4
We search the high-latitude portion of the COBE Differential Microwave Radiometers (DMR) 4-year sky maps for evidence of a non-Gaussian temperature distribution in the cosmic micro…
2-Point Correlations in the COBE DMR 4-Year Anisotropy Maps
G. Hinshaw, A. J. Banday, C. L. Bennett +5
The 2-point temperature correlation function is evaluated from the 4-year COBE DMR microwave anisotropy maps. We examine the 2-point function, which is the Legendre transform of th…
Microwave Emission at High Galactic Latitudes
A. Kogut, G. Hinshaw, A. J. Banday +4
We use the COBE Differential Microwave Radiometers (DMR) 4-year sky maps to model Galactic microwave emission at high latitudes (|b| > 20 deg). Cross-correlation of the DMR maps wi…
Angular Power Spectrum of the Microwave Background Anisotropy seen by the COBE Differential Microwave Radiometer
E. L. Wright, C. L. Bennett, K. Gorski +2
The angular power spectrum estimator developed by Peebles (1973) and Hauser & Peebles (1973) has been modified and applied to the 4 year maps produced by the COBE DMR. The power sp…
Band Power Spectra in the COBE DMR 4-Year Anisotropy Maps
G. Hinshaw, A. J. Banday, C. L. Bennett +4
We employ a pixel-based likelihood technique to estimate the angular power spectrum of the COBE Differential Microwave Radiometer (DMR) 4-year sky maps. The spectrum is consistent…
A 23 GHz Survey of GRB Error Boxes
J. N. Hewitt, C. A. Katz, S. D. Barthelmy +11
The Haystack 37-meter telescope was used in a pilot project in May 1995 to observe GRB error boxes at 23~GHz. Seven BATSE error boxes and two IPN arcs were scanned by driving the b…
