IFIRS: An Imaging Fourier Transform Spectrometer for the Next Generation Space Telescope
نویسنده
چکیده
Due to its simultaneous deep imaging and integral field spectroscopic capability, an Imaging Fourier Transform Spectrograph (IFTS) is ideally suited to the Next Generation Space Telescope (NGST) mission, and offers opportunities for tremendous scientific return in many fields of astrophysical inquiry. We describe the operation and quantify the advantages of an IFTS for space applications. The conceptual design of the Integral Field Infrared Spectrograph (IFIRS) is a wide field (5.3× 5.3) four-port imaging Michelson interferometer.

متن کاملThe Performance and Scientific Rationale for an Ir Imaging Fourier Transform Spectrograph on a Large Space Telescope
We describe a concept for an imaging spectrograph for a large orbiting observatory such as NASA’s proposed Next Generation Space Telescope (NGST) based on an imaging Fourier transform spectrograph (IFTS). An IFTS has several important advantages which make it an ideal instrument to pursue the scientific objectives of NGST. We review the operation of an IFTS and make a quantitative evaluation of...
متن کاملCritical Comparison of 3-d Imaging approaches
Currently three imaging spectrometer architectures, tunable filter, dispersive, and Fourier transform, are viable for imaging the universe in three dimensions. There are domains of greatest utility for each of these architectures. The optimum choice among the various alternative architectures is dependent on the nature of the desired observations, the maturity of the relevant technology, and th...

متن کاملFourier Transform Spectroscopy of the submillimetre continuum emission from hot molecular cores
We have used a Fourier Transform Spectrometer on the James Clerk Maxwell Telescope to study the submillimetre continuum emission from dust in three hot molecular cores (HMC). The spectral index β of the dust emission for these sources has been determined solely within the 30GHz wide 350GHz (850μm) passband to an accuracy comparable to those determined through multi-wavelength observations. We f...
