Nonlinear objects like halos and voids exhibit a scale-dependent bias on linear scales in massive neutrino cosmologies. The shape of this scale-dependent bias is a unique signature of the neutrino masses, but the amplitude of the signal is generally small, of the order of $f_\nu$, the contribution of neutrinos to the total matter content ($\lesssim 1\%$). In this paper, we demonstrate for the first time how the strength of this signal can be substantially enhanced by using information about the halo environment at a range of scales. This enhancement is achieved by using certain combinations of the large scale Cold Dark Matter and total matter environments of halos, both of which are measurable from galaxy clustering and weak lensing surveys.

用光环环境称重中微子

像光晕和空洞这样的非线性物体在大质量中微子宇宙学中的线性尺度上表现出与尺度相关的偏差。这种与尺度相关的偏差的形状是中微子质量的独特特征，但信号的幅度通常很小，约为 $f_\nu$，中微子对总物质含量的贡献 ($\lesssim 1\%$)。在本文中，我们首次展示了如何通过使用有关一系列尺度的光环环境信息来显着增强该信号的强度。这种增强是通过使用大尺度冷暗物质和光晕总物质环境的某些组合来实现的，这两种环境都可以通过星系团聚和弱透镜调查进行测量。
