The Effect of Thermal Neutrino Motion on the Non-linear Cosmological Matter Power Spectrum
Jacob Brandbyge, Steen Hannestad, Troels Haugboelle +1
We have performed detailed studies of non-linear structure formation in cosmological models with light neutrinos. For the first time the effect of neutrino thermal velocities has b…
Precision measurements of large scale structure with future type Ia supernova surveys
Steen Hannestad, Troels Haugboelle, Bjarne Thomsen
Type Ia supernovae are currently the best known standard candles at cosmological distances. In addition to providing a powerful probe of dark energy they are an ideal source of inf…
The Velocity Field of the Local Universe from Measurements of Type Ia Supernovae
Troels Haugboelle, Steen Hannestad, Bjarne Thomsen +3
We present a measurement of the velocity flow of the local universe relative to the CMB rest frame, based on the Jha, Riess & Kirshner (2007) sample of 133 low redshift type Ia sup…
Infrared and Optical Observations of GRB 030115 and its Extremely Red Host Galaxy: Implications for Dark Bursts
Andrew Levan, Andrew Fruchter, James Rhoads +24
We present near-infrared (nIR) and optical observations of the afterglow of GRB 030115. Discovered in an infrared search at Kitt Peak 5 hours after the burst trigger, this afterglo…
Optical, Infrared, and Ultraviolet Observations of the X-Ray Flash GRB 050416A
S. T. Holland, P. T. Boyd, J. Gorosabel +25
We present ultraviolet, optical, and infrared photometry of the afterglow of the X-ray flash XRF 050416A taken between approximately 100 seconds and 36 days after the burst. We fin…
GRB 050509B: Constraints on short gamma-ray burst models
J. Hjorth, J. Sollerman, J. Gorosabel +19
We have obtained deep optical images with the Very Large Telescope at ESO of the first well-localized short-duration gamma-ray burst, GRB 050509B. From V and R imaging, initiated ~…
