еще одно, последнее сказанье...
И летопись, над которой я работал -- не то чтобы упорно, конечно -- последние 8 лет, а если считать и предысторию, то 12 лет, -- летопись закончена моя. Теперь в журнал, и ждать ответа рецензента, но, barring unexpected, это все ерунда.
Можно теперь с чистой совестью ... хм, как бы правильно эту мысль выразить в великую среду? ... обратить внимание на приближающийся праздник.
Кому интересно, про что летопись,
Chandra observations of large samples of galaxy clusters detected in X-rays by ROSAT provide a new, reliable measurement of the cluster mass functions at low and high redshifts. Statistical and systematic errors are now sufficiently small, and the redshift leverage sufficiently large for the mass function evolution to be used as a useful growth of structure based dark energy probe. In this paper, we present cosmological parameter constraints obtained from Chandra observations of 37 clusters with =0.55 derived from 400 deg^2 ROSAT serendipitous survey and 49 brightest z=~0.05 clusters detected in the All-Sky Survey. Evolution of the mass function between these redshifts requires Omega_Lambda>0 with a 5sigma significance, and constrains the dark energy equation of state parameter to w_o=-1.14+/-0.21, assuming constant w and flat universe. Cluster information also significantly improves constraints when combined with other methods. Fitting our cluster data jointly with the latest supernovae, WMAP, and baryonic acoustic oscillations measurements, we obtain w_o=-0.991+/-0.045 (stat) +/-0.039 (sys), a factor of 1.5 reduction in statistical uncertainties, and nearly a factor of 2 improvement in systematics compared to constraints that can be obtained without clusters. The joint analysis of these four datasets puts a conservative upper limit on the masses of light neutrinos, \sum m_\nu<0.33 eV at 95% CL.
Короче, никаких растущих материй, газов Чаплыгина или 5-мерных миров. Космологичекая постоянная Эйнштейна. Пока, во всяком случае :)
