infrared dark cloud (IRDC)
abr-e târik-e forusorx
Fr.: nuage sombre infrarouge
A → dark cloud characterized by a → visual extinction Av≥ 102 mag. IRDCs are opaque even at 8 μm, and can be seen in silhouette against the bright diffuse → mid-infrared emission in the → interstellar medium.

Fr.: émission infrarouge
fozuni-ye forusorx, ferehbud-e ~
Fr.: excès infrarouge
kahkešân-e forusorx (#)
Fr.: galaxie infrarouge
A galaxy that emits most of its energy in the infrared region of the spectrum. Such galaxies are thought to have unusually high rates of star formation and are also described as → starburst galaxies.
tasvirgari-ye forusorx (#)
Fr.: imagerie infrarouge
Imaging with an infrared detector.
tâbeš-e forusorx (#)
Fr.: rayonnement infrarouge
That part of the → electromagnetic radiation lying beyond the red, between the radio and the visible regions of the → electromagnetic spectrum. The wavelengths range from about 0.8 → microns (μm) to about 1000 μm. See also: → near-infrared; → mid-infrared; → far-infrared; → submillimeter radiation.
Infrared Space Observatory (ISO)
nepâhešgâh-e fazâyi-ye forusorx
Fr.: Satellite ISO
A European Space Agency satellite which carried the most sensitive infrared telescope ever launched. It operated between November 1995 and April 1998 and made particularly important observations of the dusty regions of the Universe. ISO was equipped with four science instruments: an infrared camera (CAM), a long-wavelength spectrometer (LWS), a photo-polarimeter (PHT), and a short-wavelength spectrometer (SWS). The instruments jointly covered wavelengths from 2.5 to around 240 microns with spatial resolutions ranging from 1.5 arcseconds to 90 arcseconds. Its 60 cm diameter telescope was cooled by superfluid liquid helium to temperatures of 2-4 K. The mission was a great technical, operational and scientific success. During its routine operational phase, ISO successfully made some 30,000 individual imaging, photometric, spectroscopic, and polarimetric observations ranging from objects in our own solar system to the most distant extragalactic sources.
Fr.: relevé infrarouge
Observing a large area of sky (or the whole sky) in infrared wavelengths.
durbin-e forusorx (#), teleskop-e ~ (#)
Fr.: télescope infrarouge
A telescope capable of observing → infrared radiation from astronomical objects.
rowzane-ye forusorx (#)
Fr.: fenêtre infrarouge
A range of infrared wavelengths to which the Earth's atmosphere is relatively transparent, and at which observations can be made from the ground. Infrared windows are found near wavelengths of 1.25, 1.65, 2.2, 3.6, 5.0, 10, 20, and 30 microns, and beyond 300 microns.
Same as → immersion.
rigan bordan, darigidan

Fr.: dont on peut hériter, qui peut hériter
1) Capable of being inherited.
1) Something that is or may be inherited; property passing at the
owner's death to the heir or those entitled to succeed; legacy;
something, as a quality, characteristic, or other immaterial
possession, received from progenitors or predecessors as if by
Verbal noun of → inherit.
