Galaxy assembly bias in cosmological hydrodynamical simulations: a comparison between SIMBA and IllustrisTNG
Hong-Gang Yang, Marcos Pellejero, John Peacock +1
Modelling of large-scale structure is increasingly concerned with galaxy assembly bias (GAB), the dependence of galaxy clustering on quantities other than halo mass. We investigate…
Mass dependence of halo baryon fractions from the kinetic Sunyaev-Zeldovich effect
Finn A. Roper, Yan-Chuan Cai, John A. Peacock
We detect the kinetic Sunyaev-Zeldovich imprint of peculiar motions of galaxy groups and clusters, using the photometric DESI Legacy Survey together with cosmic microwave backgroun…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
Detection of cosmological dipoles aligned with transverse peculiar velocities
Yan-Chuan Cai, John A. Peacock, Anna de Graaff +1
Peculiar velocities encode rich cosmological information, but their transverse components are hard to measure. Here, we present the first observations of a novel effect of transver…
