Fabry - Perot Imaging Spectroscopy of Starburst and AGN
To date, the most detailed studies of galactic winds have come from 3-D spectrophotometric observations with radio and Fabry-Perot interfer-ometers. Here, we report the latest results from a long-term optical survey of nearby active and starburst galaxies with the Hawaii Imaging Fabry-Perot Interferometer (HIFI) at Mauna Kea and the TAURUS-2 system in Australia. These data reveal that the outfl...
متن کاملFabry - Perot Absorption - Line Spectroscopy of NGC 7079
We report on absorption-line Fabry-Perot spectroscopy of the SB0 galaxy NGC 7079. Our data allow us to determine velocity and dispersion maps, which compare well with the results of slit observations. Our goals are to obtain a bar pattern speed and to determine the velocity ellipsoid as a function of radius; this is work in progress.
متن کاملApplications of the Fabry-perot Spectrometer to Upper Atmospheric Spectroscopy
The Fabry-Perot spectrometer can be applied to a wide range of problems in upper atmospheric spectroscopy. These vary from line-width measurements at high resolution to lowresolution problems requiring either high sensitivity or rapid time response. A number of such applications are described as have been used for measurements on the aurora, twilightglow, and dayglow from Saskatoon, Canada. Spa...
متن کاملImaging Fabry-perot Spectroscopy of Ngc 5775: Kinematics of the Diffuse Ionized Gas Halo
We present imaging Fabry-Perot observations of Hα emission in the nearly edge-on spiral galaxy NGC 5775. We have derived a rotation curve and a radial density profile along the major axis by examining position-velocity (PV) diagrams from the Fabry-Perot data cube as well as a CO 2–1 data cube from the literature. PV diagrams constructed parallel to the major axis are used to examine changes in ...
متن کاملHolographic Fabry-Perot spectrometer.
We propose a spectrum analyzer based on the properties of a hologram recorded with the field transmitted by a Fabry-Perot etalon. The spectral response of this holographic Fabry-Perot spectrometer (HFPS) is analytically investigated in the paraxial approximation and compared with a conventional Fabry-Perot etalon of similar characteristics. We demonstrate that the resolving power is twice incre...
