Journal ArticleDOI
Constraining f ( R ) gravity as a scalar-tensor theory
TL;DR: In this paper, the authors search for viable f(R) theories of gravity, making use of the equivalence between such theories and scalar-tensor gravity, and find that models can be made consistent with solar system constraints either by giving the scalar a high mass or by exploiting the so-called chameleon effect.
Journal ArticleDOI
How accurately can 21 cm tomography constrain cosmology
TL;DR: In this article, the authors quantify how the precision with which cosmological parameters can be measured depends on a broad range of assumptions, focusing on the 21 cm signal from $6lzl20$.
Journal ArticleDOI
Simulating cosmic reionization: how large a volume is large enough?
TL;DR: In this paper, the authors present the largest-volume (425 Mpc h(-1) = 607 Mpc on a side) full radiative transfer simulation of cosmic reionization to date, and show that there is significant additional power in density fluctuations at very large scales.
Journal ArticleDOI
Detecting the rise and fall of the first stars by their impact on cosmic reionization
TL;DR: In this article, the authors show that reionization began much earlier with minihalo sources than without, and was greatly extended, which boosts the intergalactic electron-scattering optical depth and the large-angle polarization fluctuations of the cosmic microwave background significantly.
Journal ArticleDOI
Constraining Torsion with Gravity Probe B
TL;DR: In this paper, it is shown that torsion can be generated by macroscopic rotating objects and can be tested experimentally using a gyroscope (without nuclear spin) such as Gravity Probe B (GPB).
