Galaxy spin as a formation probe: the stellar-to-halo specific angular momentum relation

Posti, Lorenzo; Pezzulli, Gabriele; Fraternali, F; Di Teodoro, Enrico Maria


We derive the stellar-to-halo specific angular momentum relation (SHSAMR) of galaxies at z = 0 by combining (i) the standard Acold dark matter tidal torque theory, (ii) the observed relation between stellar mass and specific angular momentum (the Fall relation), and (iii) various determinations of the stellar-to-halo mass relation (SHMR). We find that the ratio f(j) = j(*)/j(h) of the specific angular momentum of stars to that of the dark matter (i) varies with mass as a double power law, (ii)...[Show more]
