Comment on "Biases in the Quasar Mass-Luminosity Plane"
What Can the Cosmic Microwave Background Tell Us About the Outer Solar System?
Daniel Babich, Cullen H. Blake, Charles Steinhardt
We discuss two new observational techniques that use observations of the Cosmic Microwave Background (CMB) to place constraints upon the mass, distance, and size distribution of sm…
Constraints on Field Theoretical Models for Variation of the Fine Structure Constant
Charles L. Steinhardt
Recent theoretical ideas and observational claims suggest that the fine structure constant alpha may be variable. We examine a spectrum of models in which alpha is a function of a…
Does the fine-structure constant vary with cosmological epoch?
John N. Bahcall, Charles L. Steinhardt, David Schlegel
We use the strong nebular lines of O III, 5007 A and 4959 A, to set a robust upper limit on the time dependence of the fine structure constant. We find |alpha^{-1} d alpha(t)/dt |…
