Anisotropy in the matter distribution beyond the baryonic acoustic oscillation scale
A. Faltenbacher, Cheng Li, Jie Wang
Tracing the cosmic evolution of the Baryonic Acoustic Oscillation (BAO) scale with galaxy two point correlation functions is currently the most promising approach to detect dark en…
Autocorrelations of stellar light and mass at z~0 and ~1: From SDSS to DEEP2
Cheng Li, Simon D. M. White, Yanmei Chen +8
We present measurements of projected autocorrelation functions w_p(r_p) for the stellar mass of galaxies and for their light in the U, B and V bands, using data from the third data…
COLD GASS, an IRAM Legacy Survey of Molecular Gas in Massive Galaxies: II. The non-universality of the Molecular Gas Depletion Timescale
Amelie Saintonge, Guinevere Kauffmann, Jing Wang +21
We study the relation between molecular gas and star formation in a volume-limited sample of 222 galaxies from the COLD GASS survey, with measurements of the CO(1-0) line from the…
COLD GASS, an IRAM legacy survey of molecular gas in massive galaxies: I. Relations between H2, HI, stellar content and structural properties
Amelie Saintonge, Guinevere Kauffmann, Carsten Kramer +21
We are conducting COLD GASS, a legacy survey for molecular gas in nearby galaxies. Using the IRAM 30m telescope, we measure the CO(1-0) line in a sample of ~350 nearby (D=100-200 M…
A tale of two populations: the stellar mass of central and satellite galaxies
Eyal Neistein, Cheng Li, Sadegh Khochfar +3
We develop a new empirical methodology to study the relation between the stellar mass of galaxies and the mass of their host subhaloes. Our approach is similar to abundance matchin…
