Equalizing the Pixel Response of the Imaging Photoelectric Polarimeter Onboard the IXPE Mission
The Gas Pixel Detector is a gas detector, sensitive to the polarization of X-rays, currently flying onboard the Imaging X-ray Polarimetry Explorer (IXPE)—the first observatory dedicated to X-ray polarimetry.

Timing Calibration of the NuSTAR X-Ray Telescope [PDF]
Abstract The Nuclear Spectroscopic Telescope Array (NuSTAR) mission is the first focusing X-ray telescope in the hard X-ray (3–79 keV) band. Among the phenomena that can be studied in this energy band, some require high time resolution and stability: rotation-powered and accreting millisecond pulsars, fast variability from black holes ...

Diffractive X-Ray Telescopes [PDF]
Diffractive X-ray telescopes using zone plates, phase Fresnel lenses, or related optical elements have the potential to provide astronomers with true imaging capability with resolution several orders of magnitude better than available in any other waveband.

A Focusing X-Ray Telescope Monochromator [PDF]
In order to resolve clusters of X-ray lines emitted by flares (Fritz et al, 1967; Neupert and Swartz, 1970) and to determine line shapes, a considerable resolving power is needed. The angular size of flares, typically about 2’ will not allow the necessary resolution to be obtained without a very fine slit system combined with the flat crystal X-ray ...

Virtual Telescope for X-Ray Observations
Selected by NASA for an Astrophysics Science SmallSat study, The Virtual Telescope for X-Ray Observations (VTXO) is a small satellite mission being developed by NASAs Goddard Space Flight Center (GSFC) and New Mexico State University (NMSU). VTXO will perform X-ray observations with an angular resolution around 50 milliarcseconds, an order of magnitude

Searching for Axion-Like Particles with X-ray Polarimeters
X-ray telescopes are an exceptional tool for searching for new fundamental physics. In particular, X-ray observations have already placed world-leading bounds on the interaction between photons and axion-like particles (ALPs).

Spectral Energy Distributions of Southern Binary X-Ray Sources
The rapid variability of X-ray binaries (XRBs) produces a wide range of X-ray states that are linked to activity across the electromagnetic spectrum. It is particularly challenging to study a sample of sources large enough to include all types in their ...

An extraordinary view of the universe: The use of X-ray vision in space science
X-ray emission from cosmic sources indicates that these sources are heated to temperatures exceeding a million degrees or that they contain highly energetic particles.
