30 Jun 2015 | Abstract: | We present a new integral-field spectroscopic dataset of the central part of
the Orion Nebula (M 42), observed with the MUSE instrument at the ESO VLT. We
reduced the data with the public MUSE pipeline. The output products are two
FITS cubes with a spatial size of ~5.9’x4.9’ (corresponding to ~0.76 pc x 0.63
pc) and a contiguous wavelength coverage of 4595...9366 Angstrom, spatially
sampled at 0.2". We provide two versions with a sampling of 1.25 Angstrom and
0.85 Angstrom in dispersion direction. Together with variance cubes these files
have a size of 75 and 110 GiB on disk. They represent one of the largest
integral field mosaics to date in terms of information content. We make them
available for use in the community. To validate this dataset, we compare world
coordinates, reconstructed magnitudes, velocities, and absolute and relative
emission line fluxes to the literature and find excellent agreement. We derive
a two-dimensional map of extinction and present de-reddened flux maps of
several individual emission lines and of diagnostic line ratios. We estimate
physical properties of the Orion Nebula, using the emission line ratios [N II]
and [S III] (for the electron temperature $T_e$) and [S II] and [Cl III] (for
the electron density $N_e$), and show two-dimensional images of the velocity
measured from several bright emission lines. | Source: | arXiv, 1507.0006 | Services: | Forum | Review | PDF | Favorites |
