Unmodified Gravity
Fergus Simpson, Brendan M. Jackson, John A. Peacock
By relaxing the conventional assumption of a purely gravitational interaction between dark energy and dark matter, substantial alterations to the growth of cosmological structure c…
Power suppression from disparate mass scales in effective scalar field theories of inflation and quintessence
Mar Bastero-Gil, Arjun Berera, Brendan M. Jackson
A scalar potential coupled to other fields of large disparate masses will exhibit power suppression of the quantum loop corrections from these massive fields. Quintessence fields i…
Hybrid Quintessential Inflation
Mar Bastero-Gil, Arjun Berera, Brendan M. Jackson +1
A model is presented in which a single scalar field is responsible for both primordial inflation at early times and then dark energy at late times. This field is coupled to a secon…
Total mass distributions of Sersic galaxies from photometry $&$ cent\ ral velocity dispersion
Dalia Chakrabarty, Brendan Jackson
We develop a novel way of finding total mass density profiles in Sersic ellipticals, to about 3 times the major axis effective radius, using no other information other than what is…
On the large-scale instability in interacting dark energy and dark matter fluids
Brendan M Jackson, Andy Taylor, Arjun Berera
Recently, Valiviita et al. (2008) have reported a large-scale early-time instability in coupled dark energy and dark matter models. We take the same form of energy-momentum exchang…
