Abstract: |
In order to extend the current suite of instruments offered in the Observatorio
Astrofísico Guillermo Haro (OAGH) in Cananea, Mexico (INAOE), and to explore a
second-generation instrument for the future 6.5 m Telescopio San Pedro Martir
(TSPM), we propose a prototype instrument that will provide un-biased wide-field
(few arcmin) spectroscopic information, with the flexibility of operating at
different spectral resolutions (R∼1–104), with a spatial resolution
limited by seeing, and therefore to be used in a wide range of astronomical
problems. This instrument will make use of the Fourier Transform Spectroscopy
technique, which has been proved to be feasible in the optical wavelength range.
Here we give the basic technical description of a Fourier transform
spectrograph, as well as the technical advantages and weaknesses, and the science
cases in which this instrument can be implemented. |
