Far-infrared and sub-mm observations of the Crab nebula
We present far-infrared (FIR) and sub-mm images of the Crab nebula, taken with the ISOPHOT instrument on board the Infrared Space Observatory (ISO) and with the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope. The ISOPHOT observations were made in the bands centred at 60, 100, 170 μm, with FWHM of equivalent area Gaussian beams of 44, 47 and 93 arcsec, res...
متن کاملThe Crab Nebula at 1 . 3 mm evidence for a new synchrotron component ⋆
We present the results of 1.3 mm observations of the Crab Nebula, performed with the MPIfR bolometer arrays at the IRAM 30-m telescope. The maps obtained, of unprecedented quality at these wavelengths, allow a direct comparison with high-resolution radio maps. Although the spatial structure of the Crab Nebula does not change much from radio to millimetre wavelengths, we have detected significan...
متن کاملObservations of the Crab Nebula at Tev Energies
The results of four years of observation of the Crab Nebula at TeV energies by the Whipple group are discussed and the status of the Crab Nebula as a standard candle for TeV astronomy is reviewed.
متن کاملThe Crab Nebula at 850 Μ Μ Μ Μ Μm
Observations of the Crab Nebula at 850 µm made with the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope are presented. A variety of chop-throws and scanning directions was used in these observations, to well sample structure over a range of scales and directions. The resulting image, which was restored using a MEM algorithm, has a resolution of 17 arcsec, ...
متن کاملCrab nebula of life.
Crabs—those sometimes pesky, hard-shelled beachcombers—are a highly diverse animal, with some 7,000 species found in oceans, lakes, and on land, varying in size from the diminutive pea crab (millimeters) to the giant 4-m wide Japanese spider crab. Tsang et al. (2014) have constructed the most complete and extensive data set to date. Their recalibrated crab gene tree using DNA and mitochondrial ...
