X-ray observations of the starburst galaxy NGC 253:II. Extended emission from hot gas in the nuclear area, disk, and halo
W. Pietsch, A. Vogler, U. Klein +1
Spatial and spectral analysis of deep ROSAT HRI and PSPC observations of the near edge-on starburst galaxy NGC 253 reveal diffuse soft X-ray emission, which contributes 80% to its…

Dust in the Wheel: The Cartwheel Galaxy in the Mid-IR
V. Charmandaris, O. Laurent, I. F. Mirabel +5
We present mid-infrared images at and of ``The Cartwheel'' (AM~0035-33), the prototypical collisional ring galaxy. The observations, taken with ISOCAM, reveal the…

Time-dependent accretion and ejection implied by pre-stellar density profiles
R. Henriksen, P. Andre, S. Bontemps
Recent observations suggest that mass ejection and mass accretion both decline significantly with time during early protostellar evolution (Bontemps et al. 1996). In the present pa…
