摘要：

We analyze H alpha or CO rotation curves extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy star formation (z similar to 0.6-2.5), more than doubling the previous sample presented by Genzel et al. and Price et al. The observations were taken with SINFONI and KMOS integral-field spectrographs at the ESO-Very Large Telescope, LUCI-LBT, NOEMA-IRAM, and Atacama Large Millimeter/submillimeter Array. We fit the major-axis kinematics with beam-convolved, forward models of turbulent rotating disks with bulges embedded in dark matter (DM) halos, including the effects of pressure support. The fraction of dark to total matter within the disk effective radius (R (e) similar to 5 kpc), f (DM)(R (e)) = V (2) (DM)(R (e))/V (2) (circ)(R (e)) decreases with redshift: at z similar to 1 (z similar to 2) the median DM fraction is 0.38 +/- 0.23 (0.27 +/- 0.18), and a third (half) of all galaxies are maximal disks with f (DM)(R (e)) < 0.28. DM fractions correlate inversely with the baryonic surface density, and the low DM fractions can be explained with a flattened, or cored, inner DM density distribution. At z similar to 2, there is approximate to 40% less DM mass on average within R (e) compared to expected values based on cosmological stellar-mass-halo-mass relations. The DM deficit is more evident at high star formation rate surface densities (greater than or similar to 2.5 M (circle dot) yr(-1) kpc(2)) and galaxies with massive bulges (>= 10(10) M (circle dot)). A combination of stellar or active galactic nucleus feedback, and/or heating due to dynamical friction, may drive the DM from cuspy into cored mass distributions, pointing to an efficient buildup of massive bulges and central black holes at z similar to 2 SFGs.
