高阶相对论性星系数计数:支配项

Higher order relativistic galaxy number counts: dominating terms

Jeppe Trøst Nielsen, Ruth Durrer

摘要:

我们回顾了二阶的计数,集中在子视界尺度上占主导地位的条款。我们重新推导这些条款的结果,并将其与文献中发现的不同版本进行比较。我们将推导推广到高阶项,特别是计算1-循环对功率谱的贡献所需的三阶数计数。

英文摘要:

We review the number counts to second order concentrating on the terms which dominate on sub horizon scales. We re-derive the result for these terms and compare it with the different versions found in the literature. We generalize our derivation to higher order terms, especially the third order number counts which are needed to compute the 1-loop contribution to the power spectrum.
