About the Plethora of X-ray Telescopes!

• “Plethora” meaning a lot. Many different types.

Chandra X-ray Observatory

• Chandra is designed to observe X-rays from high energy regions of the universe, such as hot gas in the remnants of exploded stars.

• Chandra detects and images X-ray sources that are billions of light years away. The imaging mirrors on Chandra are some of the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed.

• The images Chandra makes are twenty-five times sharper than the best previous X-ray telescope.

• Chandra's improved sensitivity is making possible more detailed studies of black holes, supernovae, and dark matter.

Constellation-X

• The Constellation-X consists of four X-ray telescopes or satellites that will detect a broader range of X-ray wavelengths than anycurrent technology, especially X-rays at higher frequencies

• Constellation-X's total light collecting area is 3 square meters, a hundred times greater than the finest current instruments

• With the increased light gathering ability will allow Constellation-X to observe extremely faint X-ray emitting sources within our Galaxy and far beyond.

• Its four satellites will orbit together in space about a few hundred miles from each other, and will detect and collect X-ray photons.

ASCA

• Is Japan's fourth cosmic X-ray astronomy mission, and the second for which the United States is providing part of the scientific payload.

• Has played an important role in the astrophysicists' never-ending quest for better X-ray spectra

•There are two types of detectors on board ASCA --- 2 Gas Imaging Spectrometers (GIS) and 2 Solid-state Imaging Spectrometers (SIS)

RXTE • It probes show the physics of cosmic X-

ray sources by making sensitive measurements of their variability over time scales ranging from milliseconds to years.

• Designed for detecting transient events, X-ray bursts, and periodic fluctuations in X-ray emissions

• RXTE has three instruments. 1. The Proportional Counter

Array (PCA) has five xenon gas proportional counter detectors.

2. The High Energy X-ray Timing Experiment (HEXTE) extends the X-ray sensitivity so that with the PCA, the two together form an excellent high resolution, sensitive X-ray detector.

3. The All Sky Monitor (ASM) rotates in such a way as to scan most of the sky every 1.5 hours, monitoring the long-term behavior of a number of the brightest X-ray sources, and giving observers an opportunity to spot any new phenomenon quickly.

ASTRO-E

• By the first stage of the M-V launch vehicle had a burn through that caused loss of attitude control.• By the second and third stages finished, there was not enough velocity to reach orbit.• It was a huge blow to the astronomical community. • ASTRO-E was designed for "broad-band, high-sensitivity, high-resolution" spectroscopy.• Four of the telescopes focused x-rays onto imaging CCD detectors. • The fifth telescope focused x-rays onto the microcalormeter.
