Sentences with phrase «submillimeter wavelengths»
Submillimeter wavelengths refer to a range of electromagnetic waves that are shorter than a millimeter but longer than infrared waves. These waves are used in scientific research and technology to study and observe objects in space, such as stars and galaxies. Full definition

Dusty galaxies do emit strong radio waves with submillimeter wavelengths, but radio telescopes typically have not had the resolution needed to pin - point individual galaxies.
Located 12.3 billion light - years away, the galaxy shone brightly in submillimeter wavelengths, which sit between radio and infrared in the electromagnetic spectrum.
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual properties of dusty star - forming galaxies.
In observations with ALMA (Atacama Large Millimeter / submillimeter Array), a gigantic radio telescope which will be constructed at 5000 - meter altitude in Chile, this generation technique of millimeter / submillimeter wavelengths using the photonic technology will play an important role in detecting faint radio signals from the universe.
Finally, the National Astronomical Observatory of Japan (NAOJ) proposed the construction of a Large Millimeter / Submillimeter Array (LMSA), which considered the same amount of antennas as ESO, but with a 10 - meter diameter, and unlike the others, it also planned to receive submillimeter wavelengths.
This research was presented in a paper «First Detection of Equatorial Dark Dust Lane in a Protostellar Disk at Submillimeter Wavelength,» by Lee et al. to appear in the journal Science Advances.
As this light travels the vast cosmic distances to Earth, the ongoing expansion of the universe shifts the once infrared light into longer millimeter and submillimeter wavelengths, all thanks to the Doppler effect.
Astronomers have struggled to explain various features seen in the disk, including a warp apparent at submillimeter wavelengths, an X-shaped pattern visible in scattered light, and vast clumps of carbon monoxide gas.
ALMA will consist of 64 12 - meter - diameter dish antennas comprising a single imaging telescope to study the universe at millimeter and submillimeter wavelengths — the region between radio waves and infrared waves.
The telescope will observe the universe at millimeter and submillimeter wavelengths, between infrared light and radio waves in the electromagnetic spectrum.
These are expected to have become rapidly enshrouded in the dust produced by the first stars; the dust absorbs much of the starlight making the galaxies difficult to see in the optical wavebands, but these same galaxies shine brightly at millimeter and submillimeter wavelengths.
He made a great contribution to designing the configuration of 16 antennas composing the Atacama Compact Array (ACA) manufactured by Japan, as well as to realizing high - resolution and high - quality imaging at millimeter / submillimeter wavelengths to further enhance the performance of ALMA.
Now with ALMA at a resolution of 8 AU, which is 25 times higher, we not only detect but also spatially resolve the dusty disk at submillimeter wavelength.
For the first time, this dark lane is seen at submillimeter wavelength, producing a «hamburger» - shaped appearance that is reminiscent of the scattered - light image of an edge - on disk in optical and near infrared.
ALMA, the largest astronomical project in existence, is a revolutionary telescope, comprising an array of 66 or more giant 12 - meter and 7 - meter diameter antennas observing at millimeter and submillimeter wavelengths.
ALMA can detect this dust from the early Universe, which is present in the most distant and ancient galaxies, thanks to submillimeter wavelengths.
Japanese participation will allow enhanced imaging and spectroscopy, especially at submillimeter wavelengths.
«Only a few gravitationally lensed galaxies have been found before at these submillimeter wavelengths, but now ALMA's found dozens of them.
This site provides the exceptionally dry atmospheric conditions necessary for astronomical observations at millimeter and submillimeter wavelengths (wavelengths between the radio and far - infrared spectral regions).
