Relation between the local width and linear halo mass density of cosmic filaments
arxiv(2024)
摘要
Large-scale cosmic filaments may have played an important role in shaping the
properties of galaxies. Meanwhile, cosmic filaments are believed to harbor a
substantial portion of the missing baryons at redshift z < 2. To inspect the
role of filaments in these issues, many properties of filaments need to be
examined, including their lengths, thicknesses, and density profiles. However,
measuring some of these properties poses challenges. This study concentrates on
estimating filament width/thickness, investigating potential correlations
between the local width of filaments and the properties of dark matter halos
within filaments. We find that the local width of filaments generally increases
with the mass of dark matter halos embedded in filaments per unit length,
roughly following a secondorder polynomial, although with notable scatter. We
probe and discuss means that may refine our findings. After further
verification and improvements, this relation could be applied to filament
samples constructed from the observed galaxy distribution, aiding in
understanding the roles of cosmic filaments in galaxy evolution and uncovering
the missing baryons.
