摘要: In this paper we revisit the issue of determining oscillating primordial scalar power spectrum and equation state dark energy from astronomical observations. By performing a global analysis with Markov Chain Monte Carlo method, find that current observations five-year WMAP SDSS-LRG matter spectrum, as well "union" supernovae sample, constrain index prim ordial amplitudeless than vertical bar n(amp)vertical < 0.116 w(amp)vertical 0.232 at 95% confidence level, respectively. This result shows oscillatory structures on are still allowed by data. Furthermore, point out these kinds modulation effects will be detectable (or gotten stronger constraint) in near future observations, such PLANCK satellite, LAMOST telescope currently ongoing projects SNLS.
