We study the two-point correlation function of a uniformly selected sample of 4426 luminous
optical quasars with redshift 2.9≤ z≤ 5.4 selected over 4041 deg 2 from the Fifth Data …

We present measurements of the angular diameter distance DA (z) and the Hubble
parameter H (z) at z= 0.35 using the anisotropy of the baryon acoustic oscillation (BAO) …

We study the importance of baryonic physics on predictions of the matter power spectrum as
it is relevant for forthcoming weak-lensing surveys. We quantify the impact of baryonic …

We present a precise estimate of the bulk virial scaling relation of halos formed via
hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result …

We use cosmography to present constraints on the kinematics of the Universe, without
postulating any underlying theoretical model. To this end, we use a Monte Carlo Markov …

We review and discuss horizontal branch (HB) stars in a broad astrophysical context,
including both variable and non-variable stars. A reassessment of the Oosterhoff dichotomy …

The power spectrum of density fluctuations is a foundational source of cosmological
information. Precision cosmological probes targeted primarily at investigations of dark …

We present the cosmological distance errors achievable using the baryonic acoustic
oscillations as a standard ruler. We begin from a Fisher matrix formalism that is upgraded …

We investigate potential gains in cosmological constraints from the combination of galaxy
clustering and galaxy-galaxy lensing by optimizing the lens galaxy sample selection using …

We present measurements of the angular diameter distance to and Hubble parameter at z=
0.57 from the measurement of the baryon acoustic peak in the correlation of galaxies from …
