The linear point (LP) standard ruler was identified as the basis of a purely geometric method
for exploiting the baryon acoustic oscillations (BAO). The LP exploits the BAO feature …

ABSTRACT The Linear Point (LP), defined as the mid-point between the baryon acoustic
oscillation (BAO) peak and the associated left dip of the two-point correlation function …

We develop a framework for self-consistently extracting cosmological information from the
clustering of tracers in redshift space, without relying on model-dependent templates to …

The baryon acoustic oscillations (BAO) feature in the two-point correlation function (TPCF) of
discrete tracers such as galaxies is an accurate standard ruler. The covariance matrix of the …

To a good approximation, on large scales, the evolved two-point correlation function of
biased tracers is related to the initial one by a convolution with a smearing kernel. For …

Baryon Acoustic Oscillations (BAOs) are crucial in cosmological analysis, providing a
standard ruler, as well as constraints on dark energy. In General Relativity models, the BAO …

We consider approximating the linearly evolved 2-point correlation function (2pcf) of dark
matter $\xi_ {\rm lin}(r;\boldsymbol {\theta}) $ in a cosmological model with parameters …
