President Of The Royal Society
The president of the Royal Society (PRS) is the elected Head of the Royal Society of London who presides over meetings of the society's council. After informal meetings at Gresham College, the Royal Society was officially founded on 28 November 1660 when a group of academics decided to find "a College for the Promoting of Mathematicall Experimentall Learning", acquiring a Royal Charter on 15 July 1662. The Royal Charter nominated William Brouncker as president, and stipulated that future presidents should be elected by the Council and Fellows of the society at anniversary meetings each year on St. Andrew's Day (30 November). The details of the presidency were described by the second Royal Charter, which did not set any limit on how long a president could serve. There were considerable fluctuations in the president's term of office until well into the 19th century. By then, sentiment had turned against electing wealthy amateurs solely because they might become patrons of the soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomer Royal
Astronomer Royal is a senior post in the Royal Households of the United Kingdom. There are two officers, the senior being the Astronomer Royal dating from 22 June 1675; the junior is the Astronomer Royal for Scotland dating from 1834. The post was created by King Charles II in 1675, at the same time as he founded the Royal Observatory Greenwich. He appointed John Flamsteed, instructing him "." The Astronomer Royal was director of the Royal Observatory Greenwich from the establishment of the post in 1675 until 1972. The Astronomer Royal became an honorary title in 1972 without executive responsibilities and a separate post of Director of the Royal Greenwich Observatory was created to manage the institution. The Astronomer Royal today receives a stipend of 100 GBP per year and is a member of the Royal Household, under the general authority of the Lord Chamberlain. After the separation of the two offices, the position of Astronomer Royal has been largely honorary, though the ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quasar
A quasar is an extremely Luminosity, luminous active galactic nucleus (AGN). It is pronounced , and sometimes known as a quasi-stellar object, abbreviated QSO. This emission from a galaxy nucleus is powered by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous accretion disc. Gas in the disc falling towards the black hole heats up because of friction and releases energy in the form of electromagnetic radiation. The radiant energy of quasars is enormous; the most powerful quasars have luminosity, luminosities thousands of times greater than that of a galaxy such as the Milky Way. Usually, quasars are categorized as a subclass of the more general category of AGN. The redshifts of quasars are of Expansion of the universe, cosmological origin. The term originated as a Contraction (grammar), contraction of "quasi-stellar ''[star-like]'' radio source"—because quasars were first identified during the 1950s as sour ...

Cosmic Microwave Background
In Big Bang cosmology the cosmic microwave background (CMB, CMBR) is electromagnetic radiation that is a remnant from an early stage of the universe, also known as "relic radiation". The CMB is faint cosmic background radiation filling all space. It is an important source of data on the early universe because it is the oldest electromagnetic radiation in the universe, dating to the epoch of recombination when the first atoms were formed. With a traditional optical telescope, the space between stars and galaxies (the background) is completely dark (see: Olbers' paradox). However, a sufficiently sensitive radio telescope shows a faint background brightness, or glow, almost uniform, that is not associated with any star, galaxy, or other object. This glow is strongest in the microwave region of the radio spectrum. The accidental discovery of the CMB in 1965 by American radio astronomers Arno Penzias and Robert Wilson was the culmination of work initiated in the 1940s, and earned th ...

Yale University
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Craig Hogan
Craig Hogan is a Professor of Astronomy and Physics at the University of Chicago and he is the director of the Fermilab Center for Particle Astrophysics. He is known for his theory of " holographic noise", which holds that holographic principle may imply quantum fluctuations in spatial position that would lead to apparent background noise or holographic noise measurable at gravitational wave detectors, in particular GEO 600.

Roger Blandford
Roger David Blandford, FRS, FRAS (born 1949) is a British theoretical astrophysicist, best known for his work on black holes. Early life Blandford was born in Grantham, England and grew up in Birmingham. Career Blandford is famous in the astrophysical community for the Blandford-Znajek process which is a mechanism for powering relativistic jets by the extraction of rotational energy from a black hole. The Blandford-Znajek mechanism has been invoked by the Event Horizon Telescope Collaboration to explain the jet power in the first observation of a black hole shadow in the giant elliptical galaxy M87. Blandford also theorized another mechanism for jet formation through hydromagnetic winds launched from accretion disks. In addition to the Blandford-Znajek and Blandford-Payne mechanisms for the formation of relativistic jets, Roger Blandford also helped devise a widely used theoretical model for jet geometric and spectral properties, the Blandford-Königl conical jet model, used ...
