WebJan 14, 2016 · The photosphere models, on the other hand, predict too hard on the spectrum. A pure blackbody emission in Rayleigh–Jeans regime predicts α ∼ +1. Relativistic effects (equal-arrival-time surface effect) would soften it to α ∼ +0.4 (e.g., Beloborodov 2010; Deng & Zhang 2014), which is still too hard compared to the data. WebThe DSFG spectra depart from the Rayleigh-Jeans regime of an optically thin modified blackbody between 218 and 277 GHz, consistent with optically thick emission or an …
