张量、非高斯性和势能重建的未来
Tensors, non-Gaussianities, and the future of potential reconstruction
摘要：
我们目前的预测重建的通货膨胀的潜力，预计从欧空局即将到来的普朗克测量CMB任务。我们专注于张量扰动和非高斯性的存在对重建工作的非正则暴胀模型的背景下的影响。我们认为潜在的约束不同的组合检测/零检测张量和非高斯。我们进行马尔可夫链蒙特卡罗和流分析模拟普朗克精度的数据集，以获得约束。我们发现，未能检测到非高斯性排除了成功的原始功率谱反演，极大地影响了不确定性，即使在存在张量检测。在没有张量检测的情况下，虽然无法确定暴胀的能量尺度，但可观察到的非高斯性水平提供了潜在参数误差之间的相关性，这表明可能会改进约束以获得合适的参数组合。约束优化张量和非高斯性的积极检测。
英文摘要：
We present projections for reconstruction of the inflationary potential expected from ESA's upcoming Planck Surveyor CMB mission. We focus on the effects that tensor perturbations and the presence of non-Gaussianities have on reconstruction efforts in the context of non-canonical inflation models. We consider potential constraints for different combinations of detection/null-detection of tensors and non-Gaussianities. We perform Markov Chain Monte Carlo and flow analyses on a simulated Planck-precision data set to obtain constraints. We find that a failure to detect non-Gaussianities precludes a successful inversion of the primordial power spectrum, greatly affecting uncertainties, even in the presence of a tensor detection. In the absence of a tensor detection, while unable to determine the energy scale of inflation, an observable level of non-Gaussianities provides correlations between the errors of the potential parameters, suggesting that constraints might be improved for suitable combinations of parameters. Constraints are optimized for a positive detection of both tensors and non-Gaussianities.
