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 ...
The COS-Halos survey: Rationale, design and a census of circumgalactic neutral hydrogen
(IOP Publishing, 2013)
We present the design and methods of the COS-Halos survey, a systematic investigation of the gaseous halos of
44 z = 0.15–0.35 galaxies using background QSOs observed with the Cosmic Origins Spectrograph aboard the
Hubble ...
The slow flow model of dust eflux in local star-forming galaxies
(Oxford University Press, 2013)
We develop a dust efflux model of radiation pressure acting on dust grains which
successfully reproduces the relation between stellar mass, dust opacity and star forma-
tion rate observed in local star-forming galaxies. ...
The high-ion content and kinematics of low-redshift lyman limit systems
(The American Astronomical Society, 2013)
We study the high-ion content and kinematics of the circumgalactic medium around low-redshift galaxies using a sample of 23 Lyman limit systems (LLSs) at 0.08 < z < 0.93 observed with the Cosmic Origins Spectrograph on ...
Radio-loud active calactic nucleus: is there a link between luminosity and cluster environment?
(American Physical Society, 2013)
We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project,
characterizing the cluster environments of a sample of 26 radio-loud active galactic nuclei (AGNs) at z ∼ 0.5
that ...
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 ...
VLT/XSHOOTER & Subaru/MOIRCS spectroscopy of HUDF-YD3: No evidence for Lyman-alpha emission at z=8.55
(Oxford University Press, 2013)
We present spectroscopic observations with VLT/XSHOOTER and Subaru/MOIRCS of a relatively bright Y -band drop-out galaxy in the Hubble Ultra Deep Field, first selected by Bunker et al. (2010), McLure et al. (2010) and ...
Testing foundations of modern cosmology with SKA all-sky surveys
(Proceedings of Science, 2014)
Continuum and HI surveys with the Square Kilometre Array (SKA) will allow us to probe some of
the most fundamental assumptions of modern cosmology, including the Cosmological Principle.
SKA all-sky surveys will map an ...
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 ...
