Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Gaia Data Release 1: The reference frame and the optical properties of ICRF sources
F. Mignard, S. Klioner, L. Lindegren +18
As part of the data processing for Gaia Data Release~1 (Gaia DR1) a special astrometric solution was computed, the so-called auxiliary quasar solution. This gives positions for sel…
Gaia Data Release 1: Astrometry - one billion positions, two million proper motions and parallaxes
L. Lindegren, U. Lammers, U. Bastian +80
Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during…
Using Java for distributed computing in the Gaia satellite data processing
William O'Mullane, Xavier Luri, Paul Parsons +3
In recent years Java has matured to a stable easy-to-use language with the flexibility of an interpreter (for reflection etc.) but the performance and type checking of a compiled l…
The Behaviour Of Cosmological Models With Varying-G
John D. Barrow, Paul Parsons
We provide a detailed analysis of Friedmann-Robertson-Walker universes in a wide range of scalar-tensor theories of gravity. We apply solution-generating methods to three parametri…
Formalising the Slow-Roll Approximation in Inflation
Andrew R. Liddle, Paul Parsons, John D. Barrow
The meaning of the inflationary slow-roll approximation is formalised. Comparisons are made between an approach based on the Hamilton-Jacobi equations, governing the evolution of t…
