The first three-dimensional reconstruction of a celestial object at radio wavelengths: Jupiter’s radiation belts
نویسنده
چکیده
For an object where the emission is optically thin, it is shown that the visibility measured by an interferometer is a sample of the three-dimensional Fourier transform of the object. If the object rotates, then it is possible to sample this three-dimensional Fourier space adequately, and so reconstruct the object in three dimensions. Using this principle, reconstructions of Jupiter’s synchrotron radiation belts can be formed. This paper considers the principle and practice of this reconstruction process.

Jupiter’s magnetic field as revealed by the synchrotron radiation belts II. Change of the 2-D brightness distribution with DE
We analyze the magnetic equatorial component of Jupiter’s radio synchrotron radiation belts using two-dimensional images recorded by the Australia Telescope Compact Array and the Very Large Array over a period of several years, during which DE , the Earth’s declination seen from Jupiter, changed from DE = −2.9◦ to near 0◦. The brightness distribution of the belts changed markedly. When DE = −2....
متن کاملDynamical implications of Jupiter’s tropospheric ammonia abundance
Groundbased radio observations indicate that Jupiter’s ammonia is globally depleted from 0.6 bars to at least 4–6 bars relative to the deep abundance of ∼ 3 times solar, a fact that has so far defied explanation. The observations also indicate that (i) the depletion is greater in belts than zones, and (ii) the greatest depletion occurs within Jupiter’s local 5-μm hot spots, which have recently ...
متن کاملJupiter’s magnetic field as revealed by the synchrotron radiation belts I. Comparison of a 3-D reconstruction with models of the field
We use tomographic techniques to make a 3-D reconstruction of Jupiter’s synchrotron radiation belts from Very Large Array observations at 20 cm. As in earlier observations with the Australia Telescope Compact Array, this reconstruction shows that the equatorial belt is not symmetric or planar, but is warped. The warp is related to the φ component of the magnetic field, or equivalently the magne...
متن کاملMethods to evaluate the performance of kilovoltage cone-beam computed tomography in the three-dimensional reconstruction space
Background: Cone-beam computed tomography (CBCT) scanners for image-guided radiotherapy are in clinical use today, but there has been no consensus on uniform acceptance to verify the CBCT image quality yet. The present work proposed new methods to fully evaluate the performance of CBCT in its three-dimensional (3D) reconstruction space. Materials and Methods: Compared to the traditional methods...

The selection of effective and optimal sidelap/overlap of images according to the quality, speed, cost and purpose of each UAV photogrammetric project is considered as an important parameter. Since two decades ago, several researches have been carried out based on a trial and error strategy for this purpose, in which different drones and cameras have been utilized for imaging with different sid...
