Exponential potentials and cosmological scaling solutions
Edmund J Copeland, Andrew R Liddle, David Wands
We present a phase-plane analysis of cosmologies containing a barotropic fluid with equation of state , plus a scalar field with an exponential potential $V \pr…
Gravitational memory of boson stars
Diego F Torres, Andrew R Liddle, Franz E Schunck
`Gravitational memory' refers to the possibility that, in cosmologies with a time-varying gravitational `constant', objects such as black holes may retain a memory of conditions at…
Can Inflation be Falsified?
John D Barrow, Andrew R Liddle
Despite its central role in modern cosmology, doubts are often expressed as to whether cosmological inflation is really a falsifiable theory. We distinguish two facets of inflation…
The gravitational redshift of boson stars
Franz E Schunck, Andrew R Liddle
We investigate the possible gravitational redshift values for boson stars with a self-interaction, studying a wide range of possible masses. We find a limiting value of $z_{lim} \s…
