Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

Abstract. This paper describes the laboratory program in millimeter and submillimeter spectroscopy at the Jet Propulsion Laboratory (JPL).

The program directly supports ongoing and developing field measurement programs; in particular, the Microwave Limb Sounder (MLS) now in orbit aboard the Upper Atmospheric Research Satellite (UARS), the balloon borne Submillimeter Limb Sounder (SLS), the Far Cited by: 1.

Submillimeter-Wave Atmospheric and Astrophysical Spectroscopy Our current progress in understanding the region and also prospects for future submillimeter spectroscopy are each.

Astronomy at radio, millimeter, and submillimeter (RMS) wavelengths is poised for a decade of discoveries. The Atacama Large Millimeter Array (ALMA) will be commissioned inenabling detailed studies of galaxies, star formation, and planet-forming disks, with spectral coverage from to 3 mm, at a resolution approaching 4 milli-arcseconds at the shortest wavelengths.

Vinyl cyanide (C{sub 2}H{sub 3}CN) is theorized to form in Titan’s atmosphere via high-altitude photochemistry and is of interest regarding the astrobiology of cold planetary surfaces due to its predicted ability to form cell membrane-like structures (azotosomes) in liquid rafaelrvalcarcel.com by: 6.

We present the principle of a terahertz-wave radar and its proof-of-concept experimental verification. The radar is based on a GHz resonant-tunneling-diode oscillator, whose terahertz output power can be easily modulated by superimposing the modulation signal on its bias voltage.

By using one modulation frequency and measuring the time delay of the returning signal, a relative measurement Cited by: 4. Significant scientific and technical challenges remain within the terahertz (THz) frequency regime and they have motivated an array of research activities.

Indeed, one research frontier in high frequency electronics now lies in the so-called THz (or submillimeter-wave) regime between the traditional microwave and the infrared domains. After the establishment of the Five College Radio Astronomy Observatory, particularly the meter diameter millimeter-wave telescope at the University of Massachusetts Amherst, my research switched into two new areas: the chemistry of dense interstellar clouds and the physics and chemistry of comets.Dec 12,  · A molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit the formation of molecules, most commonly molecular hydrogen (H 2).This is in contrast to other areas of the interstellar medium that contain predominantly ionized gas.As ofshe is also an external scientific member of the Max Planck Institut f"ur Extraterrestrische Physik in Garching, Germany.

Her research group focusses on molecules in star- and planet-forming regions and the importance of molecules as diagnostics of the physical processes, using observations at submillimeter and infrared wavelengths.
