The faint supernova remnant G 34.7-0.4 (W44).

MAVROMATAKIS F., BOUMIS P. and GOUDIS C.D.

Abstract (from CDS):

Flux calibrated images of the known supernova remnant G 34.7-0.4 in basic optical emission lines are presented. The low ionization images show a relatively flat flux distribution. The diffuse and patchy morphology of the detected optical emission may indicate the presence of turbulent magnetic fields. Typical observed Hα+[NII] fluxes are ∼8x10–17erg/s/cm2/arcsec2, while the [SII] fluxes are lower around 4x10–17erg/s/cm2/arcsec2. Emission in the medium ionization line of [OIII] 5007Å is not detected within our sensitivity limits, probably due to the heavy extinction towards the remnant. The long-slit spectra reveal strong [SII] and [NII] emission relative to Hα and moderate [OI] 6300Å emission. Shock velocities in the range of 110-150km/s and low electron densities are estimated. Archival MSX infrared data show emission in the south and west areas of the remnant matching rather well the optical and radio emission.
