Probing the Growth of Massive Black Holes with Black Hole-Host Galaxy Spin Correlations
Zhen Pan, Huan Yang
Supermassive black holes (SMBHs) are commonly found at the centers of their host galaxies, but their formation still remains an open question. In light of the tight correlation bet…
Probing Primordial Stochastic Gravitational Wave Background with Multi-band Astrophysical Foreground Cleaning
Zhen Pan, Huan Yang
The primordial stochastic gravitational wave background (SGWB) carries first-hand messages of early-universe physics, possibly including effects from inflation, preheating, cosmic…
Forecasted constraints on modified gravity from Sunyaev Zel'dovich tomography
Zhen Pan, Matthew C. Johnson
Observational cosmology has become an important laboratory for testing General Relativity, with searches for modified gravity forming a significant portion of the science case for…
Searching for Signatures of Dark matter-Dark Radiation Interaction in Observations of Large-scale Structure
Zhen Pan, Manoj Kaplinghat, Lloyd Knox
In this paper, we conduct a search in the latest large-scale structure measurements for signatures of the dark matter-dark radiation interaction proposed by Buen-Abad et al. (2015)…
Approximate Likelihood Approaches for Detecting the Influence of Primordial Gravitational Waves in Cosmic Microwave Background Polarization
Zhen Pan, Ethan Anderes, Lloyd Knox
One of the major targets for next-generation cosmic microwave background (CMB) experiments is the detection of the primordial B-mode signal. Planning is under way for Stage-IV expe…
A tale of two modes: Neutrino free-streaming in the early universe
Lachlan Lancaster, Francis-Yan Cyr-Racine, Lloyd Knox +1
We present updated constraints on the free-streaming nature of cosmological neutrinos from cosmic microwave background (CMB) power spectra, baryonic acoustic oscillation data, and…
Cosmic Microwave Background Acoustic Peak Locations
Zhen Pan, Lloyd Knox, Brigid Mulroe +1
The Planck collaboration has measured the temperature and polarization of the cosmic microwave background well enough to determine the locations of eight peaks in the temperature (…
Constraints on neutrino mass from Cosmic Microwave Background and Large Scale Structure
Zhen Pan, Lloyd Knox
Our tightest upper limit on the sum of neutrino mass eigenvalues comes from cosmological observations that will improve substantially in the near future, enabling a detection…
A First Detection of the Acoustic Oscillation Phase Shift Expected from the Cosmic Neutrino Background
Brent Follin, Lloyd Knox, Marius Millea +1
The unimpeded relativistic propagation of cosmological neutrinos prior to recombination of the baryon-photon plasma alters gravitational potentials and therefore the details of the…
Dependence of the Cosmic Microwave Background Lensing Power Spectrum on the Matter Density
Zhen Pan, Lloyd Knox, Martin White
The anisotropies in the cosmic microwave background (CMB) provide our best laboratory for testing models of the formation and evolution of large-scale structure. The rich features…
