A Chronological History of X-ray Astronomy Missions
In this chapter, we briefly review the history of X-ray astronomy through its missions. We follow a temporal development, from the first instruments...
-
High-Resolution Spectroscopy of X-ray Binaries
X-ray binaries, as bright local sources with short variability timescales for a wide range of accretion processes, represent ideal targets for...
-
Surveys of the Cosmic X-ray Background
We provide a highly concise overview of what X-ray surveys and their multiwavelength follow-up have revealed about the nature of the cosmic X-ray...

Cd(Zn)Te Detectors for Hard X-ray and Gamma-ray Astronomy
The energy range of hard X-rays and gamma-rays is dominated by non-thermal emissions. Physical processes such as particle acceleration, accretion,...

The Enhanced X-Ray Timing and Polarimetry Mission: eXTP
This chapter presents the main aspects of the enhanced X-ray Timing and Polarimetry mission, a flagship observatory designed to perform simultaneous...
-
In-Orbit Background for X-ray Detectors
In-orbit background is an unavoidable feature of all spaceborne X-ray detectors and arises both from cosmic sources (diffuse or point-like) and from...
-
Time Domain Methods for X-Ray and Gamma-Ray Astronomy
A variety of statistical methods for understanding variability in the time domain for low count rate X-ray and gamma-ray sources are explored....
-
Fast Radio Bursts
The era of fast radio bursts (FRBs) was open in 2007, when a very bright radio pulse of unknown origin was discovered occasionally in the archival...

The BepiColombo Mercury Imaging X-Ray Spectrometer
The Mercury Imaging X-ray Spectrometer (MIXS) and Solar Intensity X-ray and particle Spectrometer (SIXS) on board the BepiColombo mission are due to...
-
Overview on Inverse Compton X-ray Sources
Following the theoretical foundations of inverse Compton X-ray sources developed in the preceding part, this chapter reviews the experimental work...
-
Filters for X-ray Detectors on Space Missions
Thin filters and gas-tight windows are used in space to protect sensitive X-ray detectors from out-of-band electromagnetic radiation, low-energy...

A freely precessing magnetar following an X-ray outburst
Magnetars—highly magnetized neutron stars—are thought to be the most likely progenitors for fast radio bursts (FRBs). Freely precessing magnetars are...
