Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

The strong discrepancy between local and early-time (inverse distance ladder) estimates of
the Hubble constant H 0 could be pointing towards new physics beyond the concordance Λ …

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

Multimessenger gravitational-wave (GW) astronomy has commenced with the detection of
the binary neutron star merger GW170817 and its associated electromagnetic counterparts …

Primordial black holes formed in the early Universe via gravitational collapse of over-dense
regions may contribute a significant amount to the present dark matter relic density. Inflation …

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

We critically examine the state of current constraints on the dark energy (DE) equation of
state (EoS) w. Our study is motivated by the observation that, while broadly consistent with …

Early observations with the James Webb Space Telescope (JWST) have revealed the
existence of an unexpectedly large abundance of extremely massive galaxies at redshifts z≳ …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …
