Asymptotic behavior for the critical nonhomogeneous porous medium equation in low dimensions
Razvan Gabriel Iagar, Ariel Sánchez
We deal with the large time behavior for a porous medium equation posed in nonhomogeneous media with singular critical density $$ |x|^{-2}\partial_tu(x,t)=Δu^m(x,t), \quad (x,t)\in…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Baryon Acoustic Oscillations in the correlation function of LOWZ and CMASS galaxies in Data Release 12
Antonio J. Cuesta, Mariana Vargas-Magaña, Florian Beutler +20
We present distance scale measurements from the baryon acoustic oscillation signal in the CMASS and LOWZ samples from the Data Release 12 of the Baryon Oscillation Spectroscopic Su…
Gaussian covariance matrices for anisotropic galaxy clustering measurements
Jan Niklas Grieb, Ariel G. Sánchez, Salvador Salazar-Albornoz +1
Measurements of the redshift-space galaxy clustering have been a prolific source of cosmological information in recent years. Accurate covariance estimates are an essential step fo…
Position-dependent correlation function from the SDSS-III Baryon Oscillation Spectroscopic Survey Data Release 10 CMASS Sample
Chi-Ting Chiang, Christian Wagner, Ariel G. Sánchez +2
We report on the first measurement of the three-point function with the position-dependent correlation function from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) Dat…
