Optical-faint, far-infrared-bright Herschel sources in the CANDELS fields: Ultra-luminous infrared galaxies at z > 1 and the effect of source blending
(American Astronomical Society, 2014)
The Herschel very wide-field surveys have charted hundreds of square degrees in multiple far-IR
(FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical
counterpart identifications ...
Black hole - galaxy correlations without self-regulation
(American Astronomical Society, 2013)
Recent models of black hole growth in a cosmological context have forwarded a paradigm in which the growth
is self-regulated by feedback from the black hole itself. Here we use cosmological zoom simulations of galaxy
formation ...
Einstein's legacy in galaxy surveys
(Oxford University Press, 2015)
Non-Gaussianity in the primordial fluctuations that seeded structure formation produces a signal in the galaxy power spectrum on very large scales. This signal contains vital information about the primordial Universe, but ...
Hot subdwarf stars in close-up view IV. Helium abundances and the 3He isotopic anomaly of subdwarf B stars
(EDP Sciences, 2013)
Atmospheric parameters and helium abundances of 44 bright subdwarf B stars have been determined. More than half of our sample
consists of newly discovered stars from the Edinburgh Cape survey. We showed that effective ...
A null test to probe the scale dependence of the growth of structure as a test of general relativity
(Oxford University Press, 2019)
The main science driver for the coming generation of cosmological surveys is understanding dark energy that relies on testing general relativity on the largest scales. Once we move beyond the simplest explanation for dark ...
The impact of the connectivity of the cosmic web on the physical properties of galaxies at its nodes
(Oxford University Press, 2019)
We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We compare these measurements to the cosmological ...
Cosmic evolution of star-forming galaxies to z 1.8 in the faint low-frequency radio source population
(Oxford University Press, 2019)
We study the properties of star-forming galaxies selected at 610 MHz with the GMRT in a survey covering ∼1.86 deg2 down to a noise of ∼7.1 μJy beam−1. These were identified by combining multiple classification diagnostics: ...
Non-Gaussianity constraints using future radio continuum surveys and the multitracer technique
(Oxford University Press, 2019)
Tighter constraints on measurements of primordial non-Gaussianity (PNG) will allow the differentiation of inflationary scenarios. The cosmic microwave background bispectrum – the standard method of measuring the local ...
NIFTY galaxy cluster simulations – VI. The dynamical imprint of substructure on gaseous cluster outskirts
(Oxford University Press, 2019)
Galaxy cluster outskirts mark the transition region from the mildly non-linear cosmic web to the highly non-linear, virialized, cluster interior. It is in this transition region that the intracluster medium (ICM) begins ...
Using sparse gaussian processes for predicting robust inertial confinement fusion implosion yields
(arXiv, 2019)
Here we present the application of an advanced
Sparse Gaussian Process based machine learning algorithm to
the challenge of predicting the yields of inertial confinement
fusion (ICF) experiments. The algorithm is used ...
