The history of the subject began with the development in the 19th century of wave mechanics and the exploration of phenomena associated with the Doppler effect.

5 Effects from physical optics or radiative transfer.

3.2.2 Distinguishing between cosmological and local effects.

2 Measurement, characterization, and interpretation.

The value of a redshift is often denoted by the letter z, corresponding to the fractional change in wavelength (positive for redshifts, negative for blueshifts), and by the wavelength ratio 1 + z (which is >1 for redshifts, <1 for blueshifts). Other physical processes exist that can lead to a shift in the frequency of electromagnetic radiation, including scattering and optical effects however, the resulting changes are distinguishable from (astronomical) redshift and are not generally referred to as such (see section on physical optics and radiative transfer). Subtler redshifts are seen in the spectroscopic observations of astronomical objects, and are used in terrestrial technologies such as Doppler radar and radar guns. Gravitational waves, which also travel at the speed of light, are subject to the same redshift phenomena.Р”В®xamples of strong redshifting are a gamma ray perceived as an X-ray, or initially visible light perceived as radio waves. Relativistic, gravitational, and cosmological redshifts can be understood under the umbrella of frame transformation laws. The observation that all sufficiently distant light sources show redshift corresponding to their distance from Earth is known as Hubble's law.

The radiation travels through expanding space ( cosmological redshift).

towards an object in less strongly curved (flatter) spacetime ( gravitational redshift)

The radiation travels towards an object in a weaker gravitational potential, i.e.

The radiation travels between objects which are moving apart (' relativistic' redshift, an example of the relativistic Doppler effect).

In astronomy and cosmology, the three main causes of electromagnetic redshift are The terms derive from the colours red and blue which form the extremes of the visible light spectrum. The opposite change, a decrease in wavelength and simultaneous increase in frequency and energy, is known as a negative redshift, or blueshift. The suggested readings have been updated to provide students with additional information on the latest developments in astrophysics.In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The adopted system of units has been changed to SI from cgs units. The associated web site has been substantially revised and updatedto support the textbook. The revised codes incorporate the latest computer language standards. Supporting computer codes have been rewritten to improve readability and ease of use. Line art has been redrawn for greater clarity.Р”Р„dditional problems have been added at the end of each chapter, and problems from the first edition have been revised and updated as appropriate. New images have been carefully selected to reflect recent developments and discoveries in astrophysics. The text is now offered in two derivative versions to address the needs of courses that focus on galactic and extragalactic astronomy, and cosmology. Latest results from relevant fields of astrophysics are incorporated into the text and the figures.Р”В®very chapter has been revised with careful attention to the clarity of arguments and explanations. The book includes a selection of more than 500 problems. The text emphasizes computational physics, including computer problems and on-line programs.

In designing a curriculum, instructors can combine core and extended chapters with the optional advanced sections so as to meet their individual goals. Computer programs included with the text allow students to explore the physics of stars and galaxies. A condensed overview of stellar astrophysics allows the reader to understand critical processes that affect galactic structure and evolution. Fundamental physical concepts are presented early in the book to help students understand the development of ideas in later chapters.Р”В®ach topic is approached in the context of major unresolved questions in astrophysics.

The core text is geared for courses in stellar structure and evolution, while the briefer books provide additional coverage of the solar system, galactic and extragalactic astronomy, dynamics, evolution, and cosmology. The book has been updated to include the latest results from relevant fields of astrophysics and advances in our theoretical understanding of astrophysical phenomena. Ostlie describe the dramatic changes and advancements in astrophysics that have occurred over the past decade.
