... The properties of the dust grains (e.g., temperature and mass) can be derived from fitting far-IR SEDs (т??100 ЮМm). Only with SPIRE on Herschel has it been possible to get high spatial resolution at 200 to 500 ЮМm that is beyond the peak (~160 ЮМm) of dust emission in most galaxies. Aims: We investigate the differences in the fitted dust temperatures and masses determined using only 200 ЮМm data is for deriving these dust properties. ...

Their ratio cancels the cal value. bottom: Ratios polB/polA . ... Comparing the ratio of sefdA,B to the ratio of TsysA,B shows that the Tsys difference is independent of the cal value (so the problem is not a problem with the cal values) . Tsys on load,antenna from 28sep15 showed that the large pola,B difference only occurs on antenna. ...

spaceweb@oulu.fi - last update: 11 May 1998, 0900 UT . Matter in the known universe can be classified in terms of four states: solid, liquid, gaseous, and plasma . The basic distinction between solids, liquids and gases lies in the difference between the strength of the bonds that hold their constituent particles together. ... On the other hand, the transition from a gas to an ionized gas, i.e., plasma , is not a phase transition, since it occurs gradually with increasing temperature. ...

This colorful display shows tiny differences (or "anisotropies") in the Cosmic Microwave Background (CMB) over the entire sky. The average temperature is just 2.73 kelvins (2.73 degrees Celsius above absolute zero), and the temperature differences span mere millionths of a degree. ... Until now, part of the Milky Way's motion inferred from the variation in the CMB was unexplained. Astronomers have discovered that the Milky Way and neighboring galaxies are being pushed from the Local Void. ...
