The Star-Spectroscope of the Lick Observatory in 1898. Designed by James Keeler and constructed by John Brashear.. Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects.
Computational astrophysics refers to the methods and computing tools developed and used in astrophysics research. Like computational chemistry or computational physics , it is both a specific branch of theoretical astrophysics and an interdisciplinary field relying on computer science , mathematics , and wider physics .
The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power on the Texas Interconnection that supplies power to 26 million Texas customers – representing 90 percent of the state's electric load. [3] ERCOT is the first independent system operator (ISO) in the United States [4] and one of nine ISOs in North America. [5]
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
To observe neutrino interactions, detectors use photomultiplier tubes (PMTs) to detect individual photons. From the timing of the photons, it is possible to determine the time and place of the neutrino interaction. [23] If the neutrino creates a muon during its interaction, then the muon will travel in a line, creating a "track" of Cherenkov ...

Polarization of electromagnetic radiation is a useful tool for detecting various astronomical phenomenon. For example, energy can become polarized by passing through interstellar dust or by magnetic fields. Microwave energy from the primordial universe can be used to study the physics of that environment.
