We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

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 …

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 …

Our understanding of the state of the universe between the end of inflation and big bang
nucleosynthesis (BBN) is incomplete. The dynamics at the end of inflation are rich and a …

We perform a Markov Chain Monte Carlo analysis of a simple yet generic multifield inflation
model characterized by two scalar fields coupled to each other and nonminimally coupled to …

The properties of the recently discovered Higgs boson together with the absence of new
physics at collider experiments allows us to speculate about consistently extending the …

We present a minimal extension of the Standard Model (SM) providing a consistent picture
of particle physics from the electroweak scale to the Planck scale and of cosmology from …

We study the formation of primordial black holes and the generation of gravitational waves in
a class of cosmological models that are direct supersymmetric analogs of the …

Primordial black holes (PBHs) provide an exciting prospect for accounting for dark matter. In
this paper, we consider inflationary models that incorporate realistic features from high …

We generalize the Vicsek model to describe the collective behavior of polar circle swimmers
with local alignment interactions. While the phase transition leading to collective motion in …
