Ly$\alpha$ Blobs from Cold Streams Undergoing Kelvin-Helmholtz Instabilities

30 Jul 2020 Mandelker Nir Bosch Frank C. van den Nagai Daisuke Dekel Avishai Birnboim Yuval Aung Han

We present an analytic toy model for the radiation produced by the interaction between the cold streams thought to feed massive halos at high redshift and their hot CGM. We begin by deriving cosmologically motivated parameters for the streams as they enter the halo virial radius, $R_{\rm v}$, as a function of halo mass and redshift... (read more)
