The Calan-Hertfordshire Extrasolar Planet Search
J. S. Jenkins, H. R. A. Jones, K. Gozdziewski +7
The detailed study of the exoplanetary systems HD189733 and HD209458 has given rise to a wealth of exciting information on the physics of exoplanetary atmospheres. To further our u…
Curvaton decay into relativistic matter
Jani Sainio, Iiro Vilja
We consider an inflationary curvaton scenario, where the curvaton decays into two non-interacting relativistic fluids and later during the cosmological evolution one of them become…
On the complementarity of the quadrature observables
Pekka Lahti, Juha-Pekka Pellonpaa
In this paper we investigate the coupling properties of pairs of quadrature observables, showing that, apart from the Weyl relation, they share the same coupling properties as the…
On the progenitor and early evolution of the type II supernova 2009kr
M. Fraser, K. Takats, A. Pastorello +13
We report the identification of a source coincident with SN 2009kr in HST pre-explosion images. The object appears to be a single point source with an intrinsic colour V-I = 1.1 an…
The Spectral Energy Distribution of Fermi bright blazars
A. A. Abdo, M. Ackermann, M. Ajello +107
(Abridged) We have conducted a detailed investigation of the broad-band spectral properties of the γ-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS). By combining ou…
Measuring the spin of the primary black hole in OJ287
M. J. Valtonen, S. Mikkola, D. Merritt +7
The compact binary system in OJ287 is modelled to contain a spinning primary black hole with an accretion disk and a non-spinning secondary black hole. Using Post Newtonian (PN) ac…
