论文摘要
我们介绍了标准通货膨胀范式的扩展，大爆炸奇异性被各向异性反弹所取代。与大爆炸模型不同，宇宙学扰动过去是一种绝热制度。我们表明，这种情况解释了宇宙微波背景（CMB）的温度各向异性中观察到的四极调制，并且我们对剩余的角度相关函数E-E，B-B和T-E进行预测，并与非零温度相关性T-B和E-B一起测试我们的想法。我们将计算基于循环量子宇宙学预测的跳动，但我们的技术和结论也适用于其他弹跳模型。
We introduce an extension of the standard inflationary paradigm on which the big bang singularity is replaced by an anisotropic bounce. Unlike in the big bang model, cosmological perturbations find an adiabatic regime in the past. We show that this scenario accounts for the observed quadrupolar modulation in the temperature anisotropies of the cosmic microwave background (CMB), and we make predictions for the remaining angular correlation functions E-E, B-B and T-E, together with non-zero temperature-polarization correlations T-B and E-B, that can be used to test our ideas. We base our calculations on the bounce predicted by loop quantum cosmology, but our techniques and conclusions apply to other bouncing models as well.
