Evolution of star formation in the UKIDSS ultra deep survey field - I. Luminosity functions and cosmic star formation rate out of z = 1.6
(OUP, 2013)
We present new results on the cosmic star formation history in the SXDS-UDS field out to
z = 1.6. We compile narrow-band data from the Subaru Telescope and the Visible and Infrared
Survey Telescope for Astronomy (VISTA) ...
Anti-lensing: the bright side of voids
(American Physical Society, 2013)
More than half of the volume of our Universe is occupied by cosmic voids. The lensing magni ca-
tion e ect from those under-dense regions is generally thought to give a small dimming contribution:
objects on the far side ...
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 ...
