Distinguishing Dark Matter from Modified Gravity
J. A. Sellwood, A. Kosowsky
Dynamical mass discrepancies in galaxies have two possible explanations: the existence of large amounts of dark matter or the breakdown of Newtonian gravity. True dark matter halos…
The Cosmic Microwave Background
Arthur Kosowsky
This set of lectures provides an overview of the basic theory and phenomenology of the cosmic microwave background. Topics include a brief historical review; the physics of tempera…
Does Dark Matter Exist?
J. A. Sellwood, A. Kosowsky
The success of the Lambda-CDM model on large scales does not extend down to galaxy scales. We list a dozen problems of the dark matter hypothesis, some of which arise in specific m…
Seeing Sound Waves in the Early Universe
Arthur Kosowsky
Temperature and polarization power spectra of the cosmic microwave background can provide essentially incontrovertible evidence for coherent acoustic oscillations in the early univ…
Efficient Computation of Hyperspherical Bessel Functions
Arthur Kosowsky
Fast and accurate computations of the power spectrum of cosmic microwave background fluctuations are essential for comparing current and upcoming data sets with the large parameter…
Future Cosmic Microwave Background Constraints to the Baryon Density
Marc Kamionkowski, Gerard Jungman, Arthur Kosowsky +1
We discuss what can be learned about the baryon density from an all-sky map of the cosmic microwave background (CMB) with sub-degree angular resolution. With only minimal assumptio…
