论文摘要

MEV状态中的弥漫性超新星中微子背景(DSNB)代表累积宇宙中微子的发射,主要是由于核心塌陷超新星。我们估计了不同恒星形成速率密度(SFRD)模型的DSNB通量。我们发现,使用Fermi-Lat Collaporation等人得出的SFRD估算了DSNB通量。 (2018年)相对于使用Madau&Fragos(2017)的SFRD估计的通量,相对于估计的通量,($ \ $ \ $ 32 $ \%$)明显更高。这描述了DSNB通量与SFRD估计之间的敏感性,该估计表明,DSNB的未来检测可以用作约束SFRD的宝贵工具。

The Diffuse Supernova Neutrino Background (DSNB) in the MeV regime represents the cumulative cosmic neutrino emission, predominantly due to core collapse supernovae. We estimate the DSNB flux for different Star Formation Rate Density (SFRD) models. We find that the DSNB flux estimated using the SFRD derived from Fermi-LAT Collaboration et al. (2018) is significantly higher ($\approx$ 32$\%$) relative to the flux estimated using the SFRD from Madau & Fragos (2017). This depicts the sensitivity between the DSNB flux and the SFRD estimates which shows that future detection of the DSNB can be used as a valuable tool to constrain the SFRD.
