Martin White and collaborators have submitted for publication one of the first SDSS-III BOSS science papers. The paper entitled “The clustering of massive galaxies at z~0.5 from the first semester of BOSS data” uses some of the first data ever taken for BOSS last year to look at how the galaxies they are selecting populate the underlying “dark matter halos” that we believe enshroud all galaxies and clusters of galaxies. Using the first measurements of the clustering of BOSS galaxies, compared to detailed simulations of the BOSS survey, White et al. were able to show that 90% of BOSS galaxies were preferentially located to at the centers of their dark matter halos and thus excellent tracers of those halos . This is one of the main assumptions of BOSS and therefore re-assuring to check! There is still a long way to go, but it is good to see BOSS producing results. The full paper is available on the arXiv preprint server but we provide below a snapshot of the title, authors and abstract. Enjoy.
