Wedge-avoidance Fisher Forecasts for Primordial Features from Dark-Ages 21-cm Power Spectrum and Bispectrum
Chen Zhang, Furen Deng, Yidong Xu +3
The Dark Ages offer a uniquely clean window on primordial physics, making the redshifted 21-cm signal a promising probe of inflation models. Forecasts for interferometric 21-cm mea…
A Designer's Guide to Lunar Far-Side Interferometer Array: Power Spectrum Measurement and Cosmological Constraints from the Dark Ages
Yuewei Wen, Bin Yue, Yidong Xu +4
The 21-cm emission line from neutral hydrogen during the cosmic Dark Ages can be a powerful probe of cosmological models and early universe physics. This work provides a quantitati…
Sweeping Horndeski Canvas: New Growth-Rate Parameterization for Modified-Gravity Theories
Yuewei Wen, Nhat-Minh Nguyen, Dragan Huterer
We propose and numerically validate a new fitting formula that is sufficiently accurate to model the growth of structure in Horndeski theories of modified gravity for upcoming Stag…
Evidence for suppression of structure growth in the concordance cosmological model
Nhat-Minh Nguyen, Dragan Huterer, Yuewei Wen
We present evidence for a suppressed growth rate of large-scale structure during the dark-energy dominated era. Modeling the growth rate of perturbations with the ``growth index''…
Misinterpreting Modified Gravity as Dark Energy: a Quantitative Study
Yuewei Wen, Eva Nesbit, Dragan Huterer +1
Standard cosmological data analyses typically constrain simple phenomenological dark-energy parameters, for example the present-day value of the equation of state parameter, ,…
Gravity with explicit spacetime symmetry breaking and the Standard-Model Extension
Robert Bluhm, Hannah Bossi, Yuewei Wen
The Standard-Model Extension (SME) is the general phenomenological framework used to investigate Lorentz violation at the level of effective field theory. It has been used to obtai…
