Detection of Compact Nuclear X-Ray Emission in NGC 4736
Wei Cui, Dan Feldkun, Robert Braun
We report the results from a deep ROSAT PSPC observation of LINER galaxy NGC 4736. Two bright sources are detected, separated by only about 1', with the brighter one coinciding wit…
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…
Limits to the 1/4 keV Extragalactic X-ray Background
Wei Cui, Wilton T. Sanders, Dan McCammon +2
We observed several nearby face-on spiral galaxies with the ROSAT PSPC. The apparent deficiency in soft X-ray surface brightness observed at the outer portion of their disks is con…
Diffuse Soft X-ray Emission from Several Nearby Spiral Galaxies
Wei Cui, Wilton T. Sanders, Dan McCammon +2
We observed several nearby face-on spiral galaxies with the ROSAT PSPC to study their 0.1-2.0 keV diffuse emission. After the exclusion of resolved discrete sources, there is unres…
