Discovery of calcite in the solar type protostar NGC 1333-IRAS 4
We present observations, obtained with ISO-LWS, of the continuum between 50–200 μm of the solar type protostar IRAS 4, in the NGC 1333 complex. The continuum presents an excess, around 95 μm, that we demonstrate must be a dust feature. We compared the 95 μm excess with the calcite feature at 92 μm and find that it fits the observations reasonably well. There may be a further contribution from h...
متن کاملThe IRAS PSCz Dipole
We use the PSCz IRAS galaxy redshift survey to analyze the cosmological galaxy dipole out to a distance 300 h Mpc. The masked area is filled in three different ways, firstly by sampling the whole sky at random, secondly by using neighbouring areas to fill a masked region, and thirdly using a spherical harmonic analysis. The method of treatment of the mask is found to have a significant effect o...
متن کاملMid-infrared observations of the ultraluminous galaxies IRAS 14348-1447, IRAS 19254-7245, and IRAS 23128-5919⋆
We present a study of the three ultraluminous infrared galaxies IRAS14348-1447, IRAS19254-7245, and IRAS23128-5919, based on mid-infrared (MIR) spectro-imaging (5–18 μm) observations performed with ISOCAM. We find that the MIR emission from each system, which consists of a pair of interacting late type galaxies, is principally confined to the nuclear regions with diameters of 1–2 kpc and can ac...
متن کاملHigh-Resolution IRAS Maps Parallelised
The strip-scanned data obtained by the IRAS satellite are being used to produce maps of the infra red emission from large areas of the sky. The resolution is enhanced to nearly the telescope diffraction limit using Maximum Entropy Processing. The memory and processing requirements of this algorithm necessitate the use of parallel computers for large fields. We describe a number of techniques us...
متن کامل00494 + 5617 & Iras 05327 - 0457
High angular resolution far-infrared observations at 143 & 185 μm, using the TIFR 1-m balloon borne telescope, are presented for two Galactic star forming complexes associated with IRAS 00494+5617 and 05327-0457. The latter map also reveals the cold dust in OMC-3. The HIRES processed IRAS maps at 12, 25, 60 & 100 μm have also been presented for comparison. Both these regions are illuminated at ...
