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 کاملIdentification of New Near-infrared Dibs in the Orion Nebula
Large organic molecules and carbon clusters are basic building blocks of life, but their existence in the universe has not been confirmed beyond doubt. A number of unidentified absorption features (arising in the diffuse inter-stellar medium), usually called “Diffuse Inter-stellar Bands (DIBs)”, are hypothesized to be produced by large molecules. Among these, buckminsterfullerene C60 has gained...
متن کاملFar-Infrared detection of neutral atomic oxygen toward the Horsehead Nebula
We present the first detection of neutral atomic oxygen (P1– P2 fine structure line at∼63μm) toward the Horsehead photodissociation region (PDR). The cloud has been mapped with the Spitzer Space Telescope at far-IR (FIR) wavelengths using the Multiband Imaging Photometer for Spitzer (MIPS) in the spectral energy distribution (SED) mode. The [O i]63μm line peaks at the illuminated edge of the cl...
متن کاملA new Unidentified Far Infrared Band in NGC 7027
We report on the detection of a molecular band centered at ∼98 μm (∼102 cm), observed with the Infrared Space Observatory in the young Planetary Nebula NGC 7027. The band structure and intensity can not be reproduced by atomic fine structure lines, recombination lines or by the rotational emission of abundant molecules. We discuss the possible contribution of the low–energy bending modes of pur...
متن کاملA new interpretation of the far-infrared – radio correlation and the expected breakdown at high redshift
Context. Observations of galaxies up to z ∼ 2 show a tight correlation between far-infrared and radio continuum emission, suggesting a relation between star formation activity and magnetic fields in the presence of cosmic rays. Aims. We explain the far-infrared – radio continuum correlation by relating star formation and magnetic field strength in terms of turbulent magnetic field amplification...
