Constraints as a destriping tool for Hires images
Author(s): Cao, YU; Prince, Thomas A.
Abstract: Images produced from the Maximum Correlation Method sometimes suffer from visible striping artifacts, especially for areas of extended sources. Possible causes are different baseline levels and calibration errors in the ...

The IRAS Galaxy Atlas (IGA)
Author(s): Prince, Thomas A.
Abstract: In 1993 we proposed a project to NASA having the goal of producing a new infrared map of our Galaxy. In particular, we proposed to reprocess the IRAS data taken in the early 1980's using modern image processing algorithms ...

Parallelization and Algorithmic Enhancements of High Resolution IRAS Image Construction
Author(s): Cao, Yu; Prince, Thomas A.; Tereby, Susan; Beichman, Charles A.
Abstract: The Infrared Astronomical Satellite caried out a nearly complete survey of the infrared sky, and the survey data are important for the study of many astrophysical phenomena. However, many data sets at other wavelengths ...

Observations of accreting pulsars
Author(s): Prince, Thomas A.; Bildsten, Lars; Chakrabarty, Deepto; Wilson, Robert B.; Finger, Mark H.
Abstract: We discuss recent observations of accreting binary pulsars with the all-sky BATSE instrument on the Compton Gamma Ray Observatory. BATSE has detected and studied nearly half of the known accreting pulsar systems. Continuous ...

Observations of 1E 1740.7-2942 with ROSAT and the VLA
Author(s): Heindl, William A.; Prince, Thomas A.; Grunsfeld, John M.
Abstract: We have observed the Galactic black hole candidate 1E 1740.7-2942 in X-rays with both the ROSAT HRI and PSPC and at 1.5 and 4.9 GHz with the VLA. From the HRI observation we derive a position for 1E 1740.7-2942 of right ...

Rosat X-ray Satellite investigation of the Gamma-ray Source and Galactic Center Source 1E1740.7-2942
Author(s): Prince, Thomas A.
Abstract: Precise position determination of the X-ray/Gamma-ray Source 1E1740.7-2942 is investigated. The source was observed by both HRI (initially) and the PSPC (Position Sensitive Proportional Counter) in an attempt to determine ...

Timing analysis of low-energy gamma ray emission from galactic compact objects using the Gamma Ray Observatory
Author(s): Prince, Thomas A.
Abstract: The principal goal of our phase 1 investigation was the development of techniques and data analysis tools for pulsar searches and timing. After the launch of the Compton Observatory, we received from the Burst and Transient ...
