Cosmology with photometrically classified type IA supernovae from the SDSS-II supernova survey
(The American Astronomical Society, 2013)
We present the cosmological analysis of 752 photometrically–classified Type Ia Supernovae (SNe Ia)
obtained from the full Sloan Digital Sky Survey II (SDSS-II) Supernova (SN) Survey, supplemented
with host–galaxy ...
EC 10246-2707: a new eclipsing sdB + M dwarf binary⋆
(OUP, 2013)
We announce the discovery of a new eclipsing hot subdwarf B + M dwarf binary,
EC 10246-2707, and present multi-colour photometric and spectroscopic observations
of this system. Similar to other HW Vir-type binaries, the ...
Extending BEAMS to incorporate correlated systematic uncertainties
(IOP Science, 2013)
New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the
LSST will produce an unprecedented number of photometric supernova candidates, most
with no spectroscopic data. Avoiding biases in cosmological ...
Constraints on anisotropic cosmic expansion from supernovae
(Edp Sciences, 2013)
AIMS. We test the isotropy of the expansion of the Universe by estimating the hemispherical anisotropy of supernova type Ia (SN Ia) Hubble diagrams at low redshifts (z < 0.2).
METHODS. We compare the best fit Hubble ...
Galaxy correlations and the BAO in a void universe: structure formation as a test of the Copernican Principle
(IOP Science, 2013)
A suggested solution to the dark energy problem is the void model, where accelerated expansion is
replaced by Hubble-scale inhomogeneity. In these models, density perturbations grow on a radially
inhomogeneous background. ...
Cosmology on ultralarge scales with intensity mapping of the neutral hydrogen 21 cm emission: limits on primodial non-gaussianity
(American Physical Society, 2013)
The large-scale structure of the Universe supplies crucial information about the physical processes
at play at early times. Unresolved maps of the intensity of 21 cm emission from neutral hydrogen HI at redshifts z ~ 1 − ...
Periodic variations in the O-C diagrams of five pulsation frequencies of the DB white dwarf EC 20058-5234
(American Physical Society, 2013)
Variations in the pulsation arrival time of five independent pulsation frequencies of the DB white dwarf
EC 20058−5234 individually imitate the effects of reflex motion induced by a planet or companion but are
inconsistent ...
The Q/U imaging experiment instrument
(The American Astronomical Society, 2013)
The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the cosmic microwave background,
targeting the imprint of inflationary gravitational waves at large angular scales(∼1◦). Between 2008 October
and ...
The VISTA Deep Extragalactic Observations (VIDEO) survey
(Oxford University Press, 2013)
In this paper we describe the first data release of the the Visible and Infrared Survey Telescope
for Astronomy (VISTA) Deep Extragalactic Observations (VIDEO) survey. VIDEO is a
12 degree2 survey in the near-infrared ...
The star-formation history of mass-selected galaxies from the VIDEO survey
(Oxford University Press, 2014)
We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ...
