Galaxy Assembly Bias in the Stellar-to-halo Mass Relation for Red Central Galaxies from SDSS

Autor: Grecco A. Oyarzún, Jeremy L. Tinker, Kevin Bundy, Enia Xhakaj, J. Stuart B. Wyithe

Publikováno v: The Astrophysical Journal, Vol 974, Iss 1, p 29 (2024)

We report evidence of galaxy assembly bias—the correlation between galaxy properties and biased secondary halo properties at fixed halo mass ( M _H )—in the stellar-to-halo mass relation for red central galaxies from the Sloan Digital Sky Survey.

The Aemulus Project. VI. Emulation of Beyond-standard Galaxy Clustering Statistics to Improve Cosmological Constraints

Autor: Kate Storey-Fisher, Jeremy L. Tinker, Zhongxu Zhai, Joseph DeRose, Risa H. Wechsler, Arka Banerjee

Publikováno v: The Astrophysical Journal, Vol 961, Iss 2, p 208 (2024)

There is untapped cosmological information in galaxy redshift surveys in the nonlinear regime. In this work, we use the Aemulus suite of cosmological N -body simulations to construct Gaussian process emulators of galaxy clustering statistics at small

Over the next 5 yr, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4 m Mayall Telescope at Kitt Peak National Observatory to conduct the first Stage IV dark energy galaxy survey. At z < 0.6, the DESI

The Aemulus Project. V. Cosmological Constraint from Small-scale Clustering of BOSS Galaxies

Autor: Zhongxu Zhai, Jeremy L. Tinker, Arka Banerjee, Joseph DeRose, Hong Guo, Yao-Yuan Mao, Sean McLaughlin, Kate Storey-Fisher, Risa H. Wechsler

Publikováno v: The Astrophysical Journal, Vol 948, Iss 2, p 99 (2023)

We analyze clustering measurements of BOSS galaxies using a simulation-based emulator of two-point statistics. We focus on the monopole and quadrupole of the redshift-space correlation function, and the projected correlation function, at scales of 0.

Publikováno v: The Astrophysical Journal, Vol 945, Iss 1, p 16 (2023)

The PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) catalog will provide measurements of galaxy properties, such as stellar mass ( M _* ), star formation rate (SFR), stellar metallicity ( Z ), and stellar age ( t _age ), for >10 million gal
