We demonstrate the unique capabilities of Herschel to study very young luminous extragalactic young stellar objects (YSOs) by analyzing a central strip of the Large Magellanic Cloud obtained through the HERITAGE science demonstration program. ... Fitting full SEDs including the Herschel data requires us to increase the size and mass of envelopes included in the models. This implies higher accretion rates (т?Г10-4 M_т??yr-1), in agreement with previous outflow studies of high-mass protostars. ...

Theme: Early universe and fundamental physics Current data (e.g., large scale isotropy as revealed by the CMB data, the peaks in the CMB anisotropy power spectrum) support the idea of an epoch of inflation at early times during which the universe experienced exponential expansion. ... The CMB, on the other hand, offers a unique way to observe these gravity waves by their unmistakable signature in the polarization anisotropies on large angular scales, where their amplitude is the largest. ...
