The Detection of a Population of Submillimeter-Bright, Strongly-Lensed Galaxies
Mattia Negrello, R. Hopwood, G. De Zotti +86
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual p…
Completeness II: A signal-to-noise approach for completeness estimators applied to galaxy magnitude-redshift surveys
Luis Teodoro, Russell Johnston, Martin Hendry
This is the second paper in our completeness series which addresses some of the issues raised in the previous article by Johnston, Teodoro & Hendry (2007) in which we developed sta…
The Herschel-ATLAS: Evolution of the 250um luminosity function out to z=0.5
S. Dye, L. Dunne, S. Eales +65
We have determined the luminosity function of 250um-selected galaxies detected in the ~14 sq.deg science demonstration region of the Herschel-ATLAS project out to a redshift of z=0…
GRB 090417B and its Host Galaxy: A Step Towards an Understanding of Optically-Dark Gamma-Ray Bursts
Stephen T. Holland, Boris Sbarufatti, Rongfeng Shen +10
GRB 090417B was an unusually long burst with a T_90 duration of at least 2130 s and a multi-peaked light curve at energies of 15-150 keV. It was optically dark and has been associa…
A change in the optical polarization associated with a gamma-ray flare in the blazar 3C 279
LAT Collaboration, members of the 3C 279 multi-band campaign
It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet po…
Power spectrum extraction for redshifted 21-cm epoch of reionization experiments: the LOFAR case
Geraint Harker, Saleem Zaroubi, Gianni Bernardi +13
One of the aims of the Low Frequency Array (LOFAR) Epoch of Reionization (EoR) project is to measure the power spectrum of variations in the intensity of redshifted 21-cm radiation…
