Mid-infrared ISO spectroscopy of NGC 4945
H. W. W. Spoon, J. Koornneef, A. F. M. Moorwood +2
We have observed the central region of the nearby starburst galaxy NGC4945 with the mid-infrared spectrometers SWS and PHT-S aboard ISO. We do not find any evidence for the existen…
ORFEUS II echelle spectra: On the H_2/CO ratio in the LMC towards LH 10
P. Richter, K. S. de Boer, D. J. Bomans +3
ORFEUS far UV echelle spectra have been used to investigate HI, H_2 and CO absorption lines along the line of sight towards LH 10:3120 in the LMC, extending the study presented by…
ORFEUS II echelle spectra: Absorption by H_2 in the LMC
K. S. de Boer, P. Richter, D. J. Bomans +2
We present the first detection of molecular hydrogen (H_2) UV absorption profiles on the line of sight to the LMC. The star LH 10:3120 in the LMC was measured with the ORFEUS teles…
CIV absorption from hot gas inside supergiant shell LMC4 observed with HST and IUE
D. J. Bomans, K. S. de Boer, J. Koornneef +1
High resolution ultraviolet spectra with HST-GHRS of two stars in the direction of the supergiant shell LMC4 unambiguously show absorption by substantial quantities of CIV gas at v…
