Spin bias: theory and observations

I summarize here my contribution to the 62a Meeting of the Argentinian Astronomical Society. My presentation addressed the halo-galaxy connection and, in particular, the effect catted secondary halo bias, which refers to the secondary dependencies of halo clustering at fixed halo mass. In this paper...

My presentation addressed the halo-galaxy connection and, in particular, the effect catted secondary halo bias, which refers to the secondary dependencies of halo clustering at fixed halo mass. In this paper, I focused on one of these secondary dependencies, the so-called halo spin bias, which corresponds to the contribution from halo spin.

Resumo aquí mi contribución a la 62a Reunión de la Asociación Argentina de Astronomía. Mi presentación se centró en la conexión halo-galaxia y, en particular, en el fenómeno conocido como secondary halo bias. Este término engloba todas las dependencias secundarias (a masa de halo fija) de la distribución espacial de los halos. El presente artículo aborda una de estas dependencias, el llamado halo spin bias, que corresponde a la contribución del spin al agrupamiento o clustering de los halos. Muestro aquí una medida precisa del efecto, discuto algunos de los mecanismos físicos asociados con el mismo y propongo un posible método de observación basado en el efecto Sunyaev-Zel’dovich.
