The radial BAO scale and Cosmic Shear, a new observable for Inhomogeneous Cosmologies (2009)
Garcia-Bellido, Juan, Haugboelle, Troels
As an alternative explanation of the dimming of distant supernovae it has recently been advocated that we live in a special place in the Universe near the centre of a large spherical void described...

García-Bellido, Juan, Haugboelle, Troels
20 pages, 9 figures.-- PACS numbers: 98.65.Dx, 98.80.Es, 98.80.-k.-- Submitted to Journal of Cosmology and Astroparticle Physics (JCAP).
The Effect of Thermal Neutrino Motion on the Non-linear Cosmological Matter Power Spectrum (2008)
Brandbyge, Jacob, Hannestad, Steen, Haugboelle, Troels, Thomsen, Bjarne
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 been included in a...
Confronting Lemaitre-Tolman-Bondi models with Observational Cosmology (2008)
Garcia-Bellido, Juan, Haugboelle, Troels
The possibility that we live in a special place in the universe, close to the centre of a large void, seems an appealing alternative to the prevailing interpretation of the acceleration of the...
Sunyaev-Zeldovich profiles for clusters and groups of galaxies (2007)
Haugboelle, Troels, Sommer-Larsen, Jesper, Pedersen, Kristian
The Sunyaev-Zeldovich (SZ) effect gives a measure of the thermal energy and electron pressure in groups and clusters of galaxies. In the near future SZ surveys will map hundreds of systems, shedding...
Angular Signatures of Annihilating Dark Matter in the Cosmic Gamma-Ray Background (2007)
Cuoco, Alessandro, Brandbyge, Jacob, Hannestad, Steen, Haugboelle, Troels, Miele, Gennaro
The extragalactic cosmic gamma-ray background (CGB) is an interesting channel to look for signatures of dark matter annihilation. In particular, besides the imprint in the energy spectrum, peculiar...
Cuoco, Alessandro, Hannestad, Steen, Haugboelle, Troels, Kachelriess, Michael, Serpico, Pasquale D.
The arrival directions of ultrahigh energy cosmic rays (UHECRs) may show anisotropies on all scales, from just above the experimental angular resolution up to medium scales and dipole anisotropies....
Precision measurements of large scale structure with future type Ia supernova surveys (2007)
Hannestad, Steen, Haugboelle, Troels, Thomsen, Bjarne
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 information about the...
The Velocity Field of the Local Universe from Measurements of Type Ia Supernovae (2006)
Haugboelle, Troels, Hannestad, Steen, Thomsen, Bjarne, Fynbo, Johan, Sollerman, Jesper, Jha, Saurabh
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 supernovae. At a depth...
Modelling Relativistic Astrophysics at the Large and Small Scale (2005)
In this thesis different numerical methods, as well as applications of the methods to a number of current problems in relativistic astrophysics, are presented. In the first part the theoretical...
Observational constraints on particle production during inflation (2003)
Elgaroy, Oystein, Hannestad, Steen, Haugboelle, Troels
Resonant particle production, along with many other physical processes which change the effective equation of state (EOS) during inflation, introduces a step-like feature in the primordial power...
