Synergies between intensity maps of hydrogen lines
(Oxford University Press, 2018)
We study synergies between Hi 21cm and Hα intensity map observations, focusing on SKA1-
like and SPHEREx-like surveys. We forecast how well such a combination can measure features
in the angular power spectrum on the ...
Null tests of the cosmological constant using supernovae
(American Physical Society, 2014)
The standard concordance model of the Universe is based on the cosmological constant as the
driver of accelerating expansion. This concordance model is being subjected to a growing range
of inter-locking observations. ...
H-Atlas: The cosmic abundance of dust from the far-infrared background power spectrum
(IOP Science, 2013)
We present a measurement of the angular power spectrum of the cosmic far-infrared background
(CFIRB) anisotropies in one of the extragalactic fields of the Herschel Astrophysical Terahertz Large
Area Survey (H-ATLAS) at ...
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) ...
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 ...
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 ...
SKAO HI intensity mapping: blind foreground subtraction challenge
(University of the Western Cape, 2022)
Neutral Hydrogen Intensity Mapping (H I IM) surveys will be a powerful new probe of cosmology. However, strong astrophysical
foregrounds contaminate the signal and their coupling with instrumental systematics further ...
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
Isothermal dust models of Herschel-ATLAS galaxies
(Oxford University Press, 2013)
We use galaxies from the Herschel-ATLAS survey, and a suite of ancillary simulations based on an isothermal dust model, to study our ability to determine the effective dust temperature, luminosity and emissivity index of ...
