===================================================================== ==> In this proposal, more time is being requested for WKEGEL.OH_MEGA ===================================================================== In the frame of our project OH_MEGA we observed IRAS 20100-4156 with LWS02. This source is the second most luminous OH megamaser known. In our data we tentatively detected the 115 micron line of OH in emission, indicating that we may have discovered an OH IRaser.(Theoretical calculations predicted this line to be inverted. This is why we observed it.) In addition we observed the 53 micron line, which rather clearly shows up in absorption (as predicted), and the 119 micron line, which we tentatively detected as an absorption line. If the detection and identification of the 115 micron line is correct this would imply that IRAS 20100-4156 emits in this line about 10^7 solar luminosities, which would be a most interesting result. - However, the data are extremely noisy so that we are not sure about the detection. We therefore would like to apply for discretionary time in order to reobserve the 115 micron line.
