Exempel på hur man kan använda PULSARS i en mening

• Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation.
• These include stars and galaxies, as well as entirely new classes of objects, such as radio galaxies, quasars, pulsars, and masers.
• It has since played an important role in the research of meteoroids, quasars, pulsars, masers, and gravitational lenses, and was heavily involved with the tracking of space probes at the start of the Space Age.
• Hewish and Ryle were awarded the Nobel Prize in Physics in 1974 for work on the development of radio aperture synthesis and for Hewish's decisive role in the discovery of pulsars.
• Its main instrument is the Large Area Telescope (LAT), with which astronomers mostly intend to perform an all-sky survey studying astrophysical and cosmological phenomena such as active galactic nuclei, pulsars, other high-energy sources and dark matter.
• In 2014, the NRL was researching: armor for munitions in transport, high-powered lasers, remote explosives detection, spintronics, the dynamics of explosive gas mixtures, electromagnetic railgun technology, detection of hidden nuclear materials, graphene devices, high-power extremely high frequency (35–220 GHz) amplifiers, acoustic lensing, information-rich orbital coastline mapping, arctic weather forecasting, global aerosol analysis & prediction, high-density plasmas, millisecond pulsars, broadband laser data links, virtual mission operation centers, battery technology, photonic crystals, carbon nanotube electronics, electronic sensors, mechanical nano-resonators, solid-state chemical sensors, organic opto-electronics, neural-electronic interfaces and self-assembling nanostructures.
• In 1967, one of the college's PhD students, Jocelyn Bell Burnell, a researcher in the university radio astronomy group, discovered the first four pulsars, leading to a Nobel Prize for her supervisor, and, ultimately, for Bell Burnell herself, a position as a research professor at the University of Oxford.
• In 1974, Hulse and Taylor discovered the first pulsar in a binary system, named PSR B1913+16 after its position in the sky, during a survey for pulsars at the Arecibo Observatory in Puerto Rico.
• After the discovery of pulsars in 1967, optical images of the Crab Nebula taken by Keeler in 1899 were used to determine the proper motion of the Crab Pulsar.
• The circumstellar disk around the Be star expands and contracts for unknown reasons, so these are transient X-ray pulsars that are observed only intermittently, often with months to years between episodes of observable X-ray pulsation.
• The convention that arose for designating pulsars was that of using the letters PSR (Pulsating Source of Radio) followed by the pulsar's right ascension and degrees of declination.
• It has ten binary millisecond pulsars, including one (M62B) that is displaying eclipsing behavior from gas streaming off its companion, and one (M62H) with a planetary-mass companion about three times the mass of Jupiter.
• When Antony Hewish and Martin Ryle received the Nobel Prize in physics in 1974 for their work in radio astronomy and pulsars, Fred Hoyle, Hewish's fellow astronomer, argued that Jocelyn Bell Burnell should have been a co-recipient of the prize.
• Over time, pulsar wind nebulae may become bow-shock nebulae surrounding millisecond or slowly rotating pulsars.
• In 1974, Antony Hewish and Martin Ryle, who had developed revolutionary radio telescopes, became the first astronomers to be awarded the Nobel Prize in Physics, with the Royal Swedish Academy of Sciences noting that Hewish played a "decisive role in the discovery of pulsars".
• Anomalous X-ray pulsars (AXPs) are an observational manifestation of magnetars—young, isolated, highly magnetized neutron stars.
• Thorsett (UCSC) showed that different millisecond pulsars must form by at least two distinct processes.
• Within the Milky Way galaxy, LOFAR has detected many new pulsars within a few kpc from the Sun, has searched for short-lived transient events produced by stellar mergers or black hole accretion, and will search for bursts from Jupiter-like extrasolar planets.
• These accreting millisecond X-ray pulsars are thought to be the evolutionary progenitors of recycled radio millisecond pulsars.
• In 1967 (before the discovery of pulsars), Iosif Shklovsky examined X-ray and optical observations of Scorpius X-1 and correctly concluded that the radiation comes from a neutron star accreting matter from a companion.
