We report the detection of a deep broad H I 21 cm absorption system at z = 0.78 toward the radio source [HB89] 2351+456 (4C+45.51) at z = 1.992. The H I absorption was identified in a blind spectral line survey conducted at the Green Bank Telescope spanning 0.63 < z < 1.10 toward a large sample of radio continuum sources. The H I column density is NHI = 2.35×10 (Ts/f) cm , where Ts is the spin ...

Abstract Our view of the variety stellar structures pervading local Milky Way has been transformed by application clustering algorithms to Gaia catalog. In particular, several streams have recently discovered that are comprised hundreds thousands stars and span hundred parsecs. We analyze one such structure, Theia 456, a low-density stream extending nearly 200 pc 20° across sky. By supplementin...
