Non-Gaussian perturbations from multi-field inflation
Laura E. Allen, Sujata Gupta, David Wands
We show how the primordial bispectrum of density perturbations from inflation may be characterised in terms of manifestly gauge-invariant cosmological perturbations at second order…

Cosmological perturbations through a simple bounce
Laura E. Allen, David Wands
We present a detailed study of a simple scalar field model that yields non-singular cosmological solutions. We study both the qualitative dynamics of the homogeneous and isotropic…

A 13CO and C18O Survey of the Molecular Gas Around Young Stellar Clusters Within 1kpc of the Sun
Naomi A. Ridge, T. L. Wilson, S. T. Megeath +2
As the first step of a multi-wavelength investigation into the relationship between young stellar clusters and their environment we present fully-sampled maps in the J=1--0 lines o…
