Transition Redshift: New Kinematic Constraints from Supernovas
The transition redshift (deceleration/acceleration) is discussed by expanding the deceleration parameter to first order around its present value. A detailed study is carried out by considering two different parameterizations: q = q0 + q1z and q = q0 + q1z(1 + z) , and the associated free parameters (qo, q1) are constrained by 3 different supernova samples. The previous analysis by Riess et al. ...
متن کاملModel-independent global constraints on new physics.
Using effective-lagrangian techniques we perform a systematic survey of the lowest-dimension effective interactions through which heavy physics might manifest itself in present experiments. We do not restrict ourselves to special classes of effective interactions (such as ‘oblique’ corrections). We compute the effects of these operators on all currently wellmeasured electroweak observables, bot...
متن کاملModel-independent Constraints on Topcolor from Rb
We identify and compute the main corrections to Rb in Topcolor theories. They are due to the top-pions, the pseudo-Goldstone bosons associated with the chiral symmetry breaking responsible for the top quark mass, and amount to −(1− 4)%, independent of the details of the Topcolor model. We show that the cancellation of this effect against the contributions from Topcolor vector and scalar resonan...
متن کاملA Model-Independent Photometric Redshift Estimator
We derive a simple empirical photometric redshift estimator using a training set of galaxies with multiband photometry and measured redshifts in the Hubble Deep Field (HDF). This estimator is model-independent; it does not use spectral templates. The dispersion between the estimated redshifts and the spectroscopically measured ones is small; the dispersions range from σz ≃ 0.03 to 0.1 for z ∼< ...
متن کاملConstraints on from the IRAS Redshift
We measure the anisotropy of the redshift-space power spectrum in the 1.2-Jy and QDOT redshift surveys of IRAS-selected galaxies. On large scales, this anisotropy is caused by coherent peculiar motions, and gravitational instability theory predicts a distortion of the power spectrum that depends only on the ratio f(()=b 0:6 =b, where is the cosmological density parameter and b is the bias param...
