Compressing neural networks is a key step when deploying models for real-time or embedded applications.

The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR16 luminous red galaxy and emission line galaxy samples: cosmic distance and structure growth measurements using multiple tracers in configuration space

1 code implementation17 Jul 2020 Yuting Wang, Gong-Bo Zhao, Cheng Zhao, Oliver H. E. Philcox, Shadab Alam, Amélie Tamone, Arnaud de Mattia, Ashley J. Ross, Anand Raichoor, Etienne Burtin, Romain Paviot, Sylvain de la Torre, Will J. Percival, Kyle S. Dawson, Héctor Gil-Marín, Julian E. Bautista, Jiamin Hou, Kazuya Koyama, John A. Peacock, Vanina Ruhlmann-Kleider, Hélion du Mas des Bourboux, Johan Comparat, Stephanie Escoffier, Eva-Maria Mueller, Jeffrey A. Newman, Graziano Rossi, Arman Shafieloo, Donald P. Schneider

We perform a multi-tracer analysis using the complete Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) DR16 luminous red galaxy (LRG) and the DR16 emission line galaxy (ELG) samples in the configuration space, and successfully detect a cross correlation between the two samples, and find the growth rate to be $f\sigma_8=0. 342 \pm 0. 085$ ($\sim25$ per cent accuracy) from the cross sample alone.

Exploring cosmic homogeneity with the BOSS DR12 galaxy sample

Defining the scale of transition to homogeneity as the scale at which $\mathcal{D}_2(r)$ reaches 3 within $1\%$, i. e. $\mathcal{D}_2(r)>2. 97$ for $r>\mathcal{R}_H$, we find $\mathcal{R}_H = (63. 3\pm0. 7) \ h^{-1}\ \mathrm{Mpc}$, in agreement at the percentage level with the predictions of the $\Lambda$CDM model $\mathcal{R}_H=62. 0\ h^{-1}\ \mathrm{Mpc}$.
