Clustering of quasars in the First Year of the SDSS-IV eBOSS survey: Interpretation and halo occupation distribution
Sergio A. Rodríguez-Torres, Johan Comparat, Francisco Prada +10
In current and future surveys, quasars play a key role. The new data will extend our knowledge of the Universe as it will be used to better constrain the cosmological model at reds…
How are galaxies assigned to halos? Searching for assembly bias in the SDSS galaxy clustering
Mohammadjavad Vakili, ChangHoon Hahn
Clustering of dark matter halos has been shown to depend on halo properties beyond mass such as halo concentration, a phenomenon referred to as halo assembly bias. Standard halo oc…
Star Formation Quenching Timescale of Central Galaxies in a Hierarchical Universe
ChangHoon Hahn, Jeremy L. Tinker, Andrew R. Wetzel
Central galaxies make up the majority of the galaxy population, including the majority of the quiescent population at . Thus, the mechanism…
The Effect of Fiber Collisions on the Galaxy Power Spectrum Multipole
ChangHoon Hahn, Roman Scoccimarro, Michael R. Blanton +2
Fiber-fed multi-object spectroscopic surveys, with their ability to collect an unprecedented number of redshifts, currently dominate large-scale structure studies. However, physica…
The clustering of luminous red galaxies at z 0.7 from eBOSS and BOSS data
Zhongxu Zhai, Jeremy L. Tinker, ChangHoon Hahn +15
We present the first scientific results from the luminous red galaxy sample (LRG) of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). We measure the small and intermed…
Approximate Bayesian Computation in Large Scale Structure: constraining the galaxy-halo connection
ChangHoon Hahn, Mohammadjavad Vakili, Kilian Walsh +3
Standard approaches to Bayesian parameter inference in large scale structure assume a Gaussian functional form (chi-squared form) for the likelihood. This assumption, in detail, ca…
