英文摘要 | We combine the published stellar mass function (SMF) and gas scaling relations to explore the baryonic (stellar plus cold gas) mass function (BMF) of galaxies to redshift z = 3. We find evidence that at log(M-baryon/M-circle dot).> 11.3, the BMF has evolved little since z similar to 2.2. With the evolution of BMF and SMF, we investigate the baryon net accretion rate ((rho) over dot(baryon)) and stellar mass growth rate ((rho) over dot(star)) for the galaxy population of log(M-star/M-circle dot) > 10. The ratio between these two quantities, (rho)over dot(baryon)/(rho)over dot(star), decreases from (rho)over dot(baryon)/(rho)over dot(star) similar to 2 at z similar to 2.5 to (rho) over dot(baryon)/(rho) over dot(star) < 0.5 at z similar to 0.5, suggesting that massive galaxies are transforming from the "accretion-dominated" phase to the "depletion-dominated" phase from high-z to low-z. The transition of these two phases occurs at z similar to 1.5, which is consistent with the onset redshift of the decline of cosmic star formation rate density (CSFD). This provides evidence to support the idea that the decline of CSFD since z similar to 1.5 mainly results from the decline of baryon net accretion rate and star formation quenching in galaxies. |
