CO Depletion in Infrared Dark Clouds
G. Cosentino, J. C. Tan, C. Gainey +10
Infrared Dark Clouds (IRDCs) are cold, dense structures representative of the initial conditions of star formation. Many studies of IRDCs employ CO to investigate cloud dynamics. H…

Anisotropic universes with isotropic cosmic microwave background radiation
W C Lim, U S Nilsson, J Wainwright
We show the existence of spatially homogeneous but anisotropic cosmological models whose cosmic microwave background temperature is exactly isotropic at one instant of time but who…

An almost isotropic cosmic microwave temperature does not imply an almost isotropic universe
U. S. Nilsson, C. Uggla, J. Wainwright +1
In this letter we will show that, contrary to what is widely believed, an almost isotropic cosmic microwave background (CMB) temperature does not imply that the universe is ``close…
