The PAH emission spectra of Large Magellanic Cloud H II regions
... In the first step of the continuum-subtraction, an underlying dust continuum was defined. For the ISOPHOT spectra, the spline points for this continuum were located at ∼5.8 µm, in the 9–10 µm region, and at the blue base of the [S iv] 10.5 µm line. The wavelength coverage of ISOPHOT (ending at 11.6 ...

Recently, the available data on all RGs with redshift larger than two and with the measured degree of linear polarization larger than 5% in the UV (at ∼ 1300 Å) have been reexamined, and no rotation within a few degrees in the polarization for any of these eight RGs has been found.25 In addition, a ...

EXPOSE
EXPOSE is a multi-user facility mounted outside the International Space Station dedicated to astrobiology. EXPOSE was developed by the European Space Agency (ESA) for long-term spaceflights and was designed to allow exposure of chemical and biological samples to outer space while recording data during exposure.The results will contribute to our understanding of photobiological processes in simulated radiation climates of planets (e.g. early Earth, early and present Mars, and the role of the ozone layer in protecting the biosphere from harmful UV-B radiation), as well as studies of the probabilities and limitations for life to be distributed beyond its planet of origin. EXPOSE data support long-term in situ studies of microbes in artificial meteorites, as well as of microbial communities from special ecological niches. Some EXPOSE experiments investigated to what extent particular terrestrial organisms are able to cope with extraterrestrial environmental conditions. Others tested how organic molecules react when subjected for a prolonged period of time to unfiltered solar light.
