Being PC: Principal Components and Dark Energy
Roland de Putter, Eric V. Linder
Principal component analysis is considered as an addition to the well-tested parametrization w(a)=w_0+w_a(1-a) for the dark energy equation of state. This brief note cautions again…

Kinetic k-essence and Quintessence
Roland de Putter, Eric V. Linder
Dark energy models with non-canonical kinetic energy terms, k-essence, can have dynamical and sound speed properties distinct from canonical scalar fields, quintessence. Concentrat…

Using Weak Lensing to find Halo Masses
Roland de Putter, Martin White
Since the strength of weak gravitational lensing is proportional to the mass along the line of sight, it might be possible to use lensing data to find the masses of individual dark…
