L Oser, JP Ostriker, T Naab… - The Astrophysical …, 2010 - iopscience.iop.org
Cosmological simulations of galaxy formation appear to show a" two-phase" character with a
rapid early phase at z≳ 2 during which" in situ" stars are formed within the galaxy from …

The baryonic Tully–Fisher relation of gas-rich galaxies as a test of ΛCDM and MOND

SS McGaugh - The Astronomical Journal, 2012 - iopscience.iop.org
ABSTRACT The baryonic Tully–Fisher relation (BTFR) is an empirical relation between
