Inferences of in presence of a non-standard recombination
Chi-Ting Chiang, Anže Slosar
Measurements of the Hubble parameter from the distance ladder are in tension with indirect measurements based on the cosmic microwave background (CMB) data and the inverse distance…
First detection of scale-dependent linear halo bias in -body simulations with massive neutrinos
Chi-Ting Chiang, Marilena LoVerde, Francisco Villaescusa-Navarro
Using -body simulations with massive neutrino density perturbations, we detect the scale-dependent linear halo bias with high significance. This is the first time that this effe…
Probing Decoupling in Dark Sectors with the Cosmic Microwave Background
Gongjun Choi, Chi-Ting Chiang, Marilena LoVerde
The acoustic peaks in the angular power spectrum of cosmic microwave background (CMB) temperature and polarization anisotropies play an important role as a probe of the nature of n…
Power spectrum in the presence of large-scale overdensity and tidal fields: breaking azimuthal symmetry
Chi-Ting Chiang, Anže Slosar
We consider the power spectrum of a biased tracer observed in a finite volume in the presence of a large-scale overdensity and tidal fields. Expanding both the observed power spect…
