TL;DR: Using the 21 cm line, observed all-sky and across the redshift range from 0 to 5, the large scale structure of the Universe can be mapped in three dimensions as discussed by the authors.
Journal ArticleDOI
Understanding EROS2 observations toward the spiral arms within a classical Galactic model framework
TL;DR: In this paper, the authors compare the EROS microlensing observations with Galactic models (including the Besancon model), tuned to fit the EROSS source catalogs, and take into account all observational data such as the micro-lensing optical depth, the Einstein crossing durations, and the color and magnitude distributions of the catalogued stars.
