Halo model interpretations of the luminosity dependence of galaxy clustering assume that there is a central galaxy in every sufficiently massive halo, and that this central galaxy is very different from all the others in the halo. The halo model decomposition makes the remarkable prediction that the mean luminosity of the non-central galaxies in a halo should be almost independent of halo mass—...

Abstract Number words seemingly function both as adjectives attributing cardinality properties to collections, in Frege’s ‘Jupiter has four moons’, and names referring numbers, ‘The number of Jupiter’s moons is four’. This leads what Thomas Hofweber calls Other Puzzle: How can modifiers singular terms if neither nor serve multiple semantic functions? Whereas most philosophers deny that one thes...
