We review recent trends in inflationary dynamics in the context of viable modified gravity
theories. After providing a general overview of the inflationary paradigm emphasizing on …

The search for the curl component (B mode) in the cosmic microwave background (CMB)
polarization induced by inflationary gravitational waves is described. The canonical single …

I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

The current flow of high accuracy astrophysical data, among which are the Cosmic
Microwave Background (CMB) measurements by the Planck satellite, offers an …

The production of a stochastic background of gravitational waves is a fundamental
prediction of any cosmological inflationary model. The features of such a signal encode …

ABSTRACT The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide
stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We …

We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

Modern Cosmology, Third Edition provides a detailed introduction to the field of cosmology.
Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaître …

Recent observations of Type 1a supernovae indicating an accelerating universe have once
more drawn attention to the possible existence, at the present epoch, of a small positive Λ …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …
