Advanced X-ray Imaging Satellite (AXIS) is a space telescope under development by NASA for launch in 2032. [1] It is a NASA Probe mission concept designed for high angular resolution X-Ray imaging. [2] The mission goals are to examine galaxies over cosmic time, feedback in galaxies, Black Hole strong gravity, Dual AGN, the high redshift universe.
X.Org Server is the free and open-source implementation of the X Window System (X11) display server stewarded by the X.Org Foundation.. Implementations of the client-side X Window System protocol exist in the form of X11 libraries, which serve as helpful APIs for communicating with the X server. [4]
The X Window System (X11, or simply X; stylized 𝕏) is a windowing system for bitmap displays, common on Unix-like operating systems.. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. [3]
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
New details are emerging about the case against Luigi Mangione, the man indicted on murder charges in the deadly shooting of UnitedHealthcare CEO Brian Thompson in New York City. The 26-year-old ...
The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999.
A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound, which is different from radiopharmaceuticals, which emit radiation themselves.
The X-ray absorption coefficient of a material as a function of energy is obtained by directing X-rays of a narrow energy range at a sample, while recording the incident and transmitted x-ray intensity, as the incident x-ray energy is incremented.
