Searching for scalar gravitational interactions in current and future cosmological data
Alireza Hojjati, Aaron Plahn, Alex Zucca +4
Modified gravity theories often contain a scalar field of gravitational strength which interacts with matter. We examine constraints on the range and the coupling strength of a sca…
The extended Baryon Oscillation Spectroscopic Survey (eBOSS): a cosmological forecast
Gong-Bo Zhao, Yuting Wang, Ashley J. Ross +28
We present a science forecast for the eBOSS survey, part of the SDSS-IV project, which is a spectroscopic survey using multiple tracers of large-scale structure, including luminous…
POLARBEAR Constraints on Cosmic Birefringence and Primordial Magnetic Fields
POLARBEAR Collaboration, Peter A. R. Ade, Kam Arnold +84
We constrain anisotropic cosmic birefringence using four-point correlations of even-parity -mode and odd-parity -mode polarization in the cosmic microwave background measurem…
Cosmic Strings
Tanmay Vachaspati, Levon Pogosian, Daniele Steer
This article, written for Scolarpedia, provides a brief introduction into the subject of cosmic strings, together with a review of their main properties, cosmological evolution and…
Magnetic monopole - domain wall collisions
Micah Brush, Levon Pogosian, Tanmay Vachaspati
Interactions of different types of topological defects can play an important role in the aftermath of a phase transition. We study interactions of fundamental magnetic monopoles an…
Reconstruction of the dark matter-vacuum energy interaction
Yuting Wang, Gong-Bo Zhao, David Wands +2
An interaction between the vacuum energy and dark matter is an intriguing possibility which may offer a way of solving the cosmological constant problem. Adopting a general prescri…
