Exempel på hur man kan använda EXTRAGALACTIC i en mening

• He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology.
• This is in contrast to extragalactic astronomy, which is the study of everything outside our galaxy, including all other galaxies.
• As instrumentation has improved, distant objects can now be examined in more detail and so extragalactic astronomy includes objects at nearly the edge of the observable universe.
• Cepheids are important cosmic benchmarks for scaling galactic and extragalactic distances; a strong direct relationship exists between a Cepheid variable's luminosity and its pulsation period.
• Due in part to its radio luminosity and its discovery as the first identified quasar, 3C 273's right ascension in the Fifth Fundamental Catalog (FK5) is used to standardize the positions of 23 extragalactic radio sources used to define the International Celestial Reference System (ICRS).
• Eight extragalactic supernovae have so far been observed in M61, making it one of the most prodigious galaxies for such cataclysmic events.
• Uhuru achieved several outstanding scientific advances, including the discovery and detailed study of the pulsing accretion-powered binary X-Ray sources such as Cen X-3, Vela X-1, and Her X-1, the identification of Cygnus X-1, the first strong candidate for an astrophysical black hole, and many important extragalactic sources.
• The High-Energy X-ray Timing Experiment (HEXTE) is a scintillator array for the study of temporal and temporal/spectral effects of the hard X-ray (20 to 200 keV) emission from galactic and extragalactic sources.
• Surveys in the infrared, such as IRAS and 2MASS, have given a more complete picture of the extragalactic sky.
• Its energy was 20 million times greater than the highest photon energy measured in electromagnetic radiation emitted by an extragalactic object, the blazar Markarian 501.
• It is used for observations of millimetre wave emission from molecules in comets, circumstellar envelopes, and the interstellar medium in the Galaxy and in extragalactic objects.
• A remarkable achievement of the instrument was the detection of the most energetic photons observed from an extragalactic object, at 16 TeV, originating from Markarian 501 (Mrk 501).
• More specifically, the ICRF is an inertial barycentric reference frame whose axes are defined by the measured positions of extragalactic sources (mainly quasars) observed using very-long-baseline interferometry while the Gaia-CRF is an inertial barycentric reference frame defined by optically measured positions of extragalactic sources by the Gaia satellite and whose axes are rotated to conform to the ICRF.
• physicist and astronomer, known primarily for his work in astrobiology, galactic astronomy and extragalactic astronomy, history of astronomy, gnomonics, and the search for extraterrestrial intelligence (SETI).
• The album was written and recorded within weeks and captures the band in particular fine form, flaunting their trademark tortured guitar-riffing, odd time signatures and extragalactic soundscapes, lyrically hunted by the heaviness of the load.
• The main research activities done at the observatory concern extragalactic astronomy and cosmology (large-scale structure of the universe, intergalactic media), stellar physics, interstellar medium and the galaxy, the physics of the Sun and the Solar System (radioastronomy, coronal plasma, cometary and interplanetary dust), high energy astrophysics (supernovae, gamma-ray bursts), astronomical technologies (computer systems for data acquisition and control, including remote control, acquisition, handling and analysis of images, supercomputing) and space astronomy (development of space technologies and space observations).
• Paolo Padovani is an Italian astronomer working at the European Southern Observatory, specializing in the study of Active galactic nuclei including the study of quasars and blazars, evolution and multifrequency studies and extragalactic backgrounds.
• Recessional velocity is the rate at which an extragalactic astronomical object recedes (becomes more distant) from an observer as a result of the expansion of the universe.
• Likewise, the term kilomaser is used to describe masers outside the Milky Way that have luminosities of order , or thousands of times stronger than the average maser in the Milky Way, gigamaser is used to describe masers billions of times stronger than the average maser in the Milky Way, and extragalactic maser encompasses all masers found outside the Milky Way.
• The diffuse extragalactic background light (EBL) is all the accumulated radiation in the universe due to star formation processes, plus a contribution from active galactic nuclei (AGNs).
