Testing homegeneity with Galaxy Star formation histories
(IOP Publishing, 2013)
Observationally confirming spatial homogeneity on sufficiently large cosmological scales is of importance to test
one of the underpinning assumptions of cosmology, and is also imperative for correctly interpreting dark ...
Physical properties of spectroscopically-confirmed galaxies at z >= 6. II. Morphology of the rest-frame UV continuum and Lyman-alpha emission
(IOP Science, 2013)
We present a detailed structural and morphological study of a large sample of spectroscopicallyconfirmed
galaxies at z ≥ 6, using deep HST near-IR broad-band images and Subaru optical narrowband
images. The galaxy sample ...
Probing the imprint of interacting dark energy on very large scales
(American Physical Society, 2015)
The observed galaxy power spectrum acquires relativistic corrections from light-cone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infrared and radio bands will probe increasingly ...
SN Ia host galaxy properties from Sloan Digital Sky Survey-II spectroscopy
(Oxford University Press, 2013)
We study the stellar populations of Type Ia supernova (SN Ia) host galaxies using Sloan
Digital Sky Survey (SDSS)-II spectroscopy. The main focus is on the relationships of SN Ia
properties with stellar velocity dispersion ...
Physical properties of spectroscopically confirmed galaxies at Z ≥ 6. I. Basic characteristics of the rest-frame UV continuum and lyman-alpha emission
(American Astronomical Society, 2013)
We present deep HST near-IR and Spitzer mid-IR observations of a large sample of spectroscopically-
confirmed galaxies at z ≥ 6. The sample consists of 51 Ly-alpha emitters (LAEs) at z ≃ 5.7, 6.5, and 7.0,
and 16 Lyman-break ...
Nonlinear modulation of the HI power spectrum on ultra-large scales. I
(IOP Science, 2015)
Intensity mapping of the neutral hydrogen brightness temperature promises to provide a three-dimensional view of the universe on very large scales. Nonlinear effects are typically thought to alter only the small-scale ...
Hunting down horizon-scale effects with multi-wavelength surveys
(American Astronomical Society, 2015)
Next-generation cosmological surveys will probe ever larger volumes of the universe, including the largest scales, near and beyond the horizon. On these scales, the galaxy power spectrum carries signatures of local primordial ...
Radio continuum surveys with square kilometre array pathfinders
(Cambridge University Press, 2013)
In the lead-up to the Square Kilometre Array (SKA) project, several next-generation
radio telescopes and upgrades are already being built around the world. These include APERTIF
(The Netherlands), ASKAP (Australia), ...
Foreground contamination in Lyα intensity mapping during the epoch of reoinization
(IOP Science, 2014)
The intensity mapping of Lyα emission during the epoch of reionization will be contaminated by foreground
emission lines from lower redshifts. We calculate the mean intensity and the power spectrum of Lyα emission at
z ...
Continuing influence of shell effects at high-excitation energies
(Elsevier, 2019)
Empirical drops in ground-state nuclear polarizabilities indicate deviations from the effect of giant dipole
resonances and may reveal the presence of shell effects in semi-magic nuclei with neutron magic
numbers N = 50, ...
