nbodykit: an open-source, massively parallel toolkit for large-scale structure
Nick Hand, Yu Feng, Florian Beutler +4
We present nbodykit, an open-source, massively parallel Python toolkit for analyzing large-scale structure (LSS) data. Using Python bindings of the Message Passing Interface (MPI),…
Dust Obscured Star Forming Galaxies in the Early Universe
Stephen M. Wilkins, Yu Feng, Tiziana Di Matteo +3
Motivated by recent observational constraints on dust reprocessed emission in star forming galaxies at and above we use the very-large cosmological hydrodynamical simulat…
The descendants of the first quasars in the BlueTides simulation
Ananth Tenneti, Tiziana Di Matteo, Rupert Croft +2
Supermassive blackholes with masses of a billion solar masses or more are known to exist up to . However, the present-day environments of the descendants of first quasars is n…
Theoretical Systematics of Future Baryon Acoustic Oscillation Surveys
Zhejie Ding, Hee-Jong Seo, Zvonimir Vlah +3
Future Baryon Acoustic Oscillation surveys aim at observing galaxy clustering over a wide range of redshift and galaxy populations at great precision, reaching tenths of a percent,…
The clustering of galaxies: Predictions from the BLUETIDES simulation
Aklant Kumar Bhowmick, Tiziana Di Matteo, Yu Feng +1
We study the clustering of the highest-z galaxies (from ~ to a few tens Mpc scales) using the BLUETIDES simulation and compare it to current observational constraints from Hu…
Towards optimal extraction of cosmological information from nonlinear data
Uros Seljak, Grigor Aslanyan, Yu Feng +1
One of the main unsolved problems of cosmology is how to maximize the extraction of information from nonlinear data. If the data are nonlinear the usual approach is to employ a seq…
The properties of the first galaxies in the BLUETIDES simulation
Stephen M. Wilkins, Yu Feng, Tiziana Di-Matteo +3
We employ the very large cosmological hydrodynamical simulation BLUETIDES to investigate the predicted properties of the galaxy population during the epoch of reionisation ().…
Accurate halo-galaxy mocks from automatic bias estimation and particle mesh gravity solvers
Mohammadjavad Vakili, Francisco-Shu Kitaura, Yu Feng +4
Reliable extraction of cosmological information from clustering measurements of galaxy surveys requires estimation of the error covariance matrices of observables. The accuracy of…
