An All - sky Advanced X - ray Monitor ( AXM ) Mission
A concept for an all-sky monitor mission substantially more powerful than the RXTE ASM is presented in brief. It makes use of 31 Gas Electron Multiplier (GEM) proportional counters to provide continuous monitoring of the entire x-ray sky, except for earth occultations and a small region around the sun. This coverage would allow the study of a wide variety of short duration cosmic outbursts. At ...
متن کاملThe RXTE All Sky Monitor: First Year of Performance
The RXTE All Sky Monitor provides a public database that includes more than one year of X-ray monitoring observations (2-12 keV) of X-ray binaries and a few active galactic nuclei. The instrument operates with a 40% duty cycle, and the exposures yield roughly 5 celestial scans per day. There have been 109 source detections, including 16 X-ray transients, the majority of which are recurrent case...
متن کاملRxte All-sky Monitor Localization of Sgr 1627–41
The fourth unambiguously identified Soft Gamma Repeater (SGR), SGR 1627–41, was discovered with the BATSE instrument on 1998 June 15 (Kouveliotou et al. 1998). Interplanetary Network (IPN) measurements and BATSE data constrained the location of this new SGR to a 6 segment of a narrow (19) annulus (Hurley et al. 1999a; Woods et al. 1998). We present two bursts from this source observed by the Al...
متن کاملAn All-sky Optical Seti Survey
We present plans for an all-sky search for pulsed optical SETI beacons at Agassiz station in Harvard, Massachusetts. We will use a 1.8 meter f/2.5 spherical “light bucket” (2-3 arcmin resolution) focused onto a multi-pixel camera consisting of sixteen 64-pixel photomultiplier tubes (with pixels measuring 1.5 arcmin on a side) in two matched focal planes. It will observe a 1. ◦6× 0 . ◦2 patch of...
متن کاملFirst Results from the All-sky Monitor on the Rossi X-ray Timing Explorer
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 cameras that can be rotated to view different regions by a motorized drive assembly. Intensities of 1100 known sources are obtained via least-squares fits of shadow patterns to the data and compiled to form X-ray light cur...
