One- and Two-point source statistics from the LOFAR Two-metre sky survey first data release
(ESO, 2020)
Context. The LOFAR Two-metre Sky Survey (LoTSS) will eventually map the complete Northern sky and provide an excellent
opportunity to study the distribution and evolution of the large-scale structure of the Universe.
Aims. ...
K-CLASH: Strangulation and ram pressure stripping in galaxy cluster members at 0.3 < z < 0.6
(Oxford University Press, 2020-06-26)
Galaxy clusters have long been theorized to quench the star formation of their members.
This study uses integral-field unit observations from the K-band MultiObject Spectrograph
(KMOS) – Cluster Lensing And Supernova ...
A census of the pulsar population observed with the international LOFAR station FR606 at low frequencies (25–80 MHz)
(EDP Sciences, 2020)
ontext. To date, only 69 pulsars have been identified with a detected pulsed radio emission below 100 MHz. A LOFAR-core LBA census and a dedicated campaign with the Nançay LOFAR station in stand-alone mode were carried out ...
Testing galaxy formation simulations with damped Lyman-α abundance and metallicity evolution
(Oxford University Press, 2020)
We examine the properties of damped Lyman-α absorbers (DLAs) emerging from a single set of cosmological initial conditions in two state-of-the-art cosmological hydrodynamic simulations: SIMBA and TECHNICOLOR DAWN. The ...
Constraining the growth rate by combining multiple future surveys
(IOP Publishing, 2020)
The growth rate of large-scale structure provides a powerful consistency test of
the standard cosmological model and a probe of possible deviations from general relativity.
We use a Fisher analysis to forecast constraints ...
Development and application of an HDF5 schema for SKA-scale image cube visualization
(Elsevier, 2020)
In this paper, we describe an HDF5 schema created to support the efficient visualization of the large image cubes that will be produced by SKA Phase 1 and precursor radio telescopes. We demonstrate how the “HDF5-IDIA” ...
K-CLASH: spatially resolving star-forming galaxies in field and cluster environments at z ≈ 0.2–0.6
(Oxford University Press, 2020)
We present the KMOS-CLASH (K-CLASH) survey, a K-band Multi-Object Spectrograph (KMOS) survey, of the spatially resolved gas properties and kinematics of 191 (pre-dominantly blue) H α-detected galaxies at 0.2 ≲ z ≲ 0.6 in ...
The 1.28 GHz MeerKAT DEEP2 Image

Foreground modelling via Gaussian process regression: an application to HERA data
(Oxford University Press, 2020)
The key challenge in the observation of the redshifted 21-cm signal from cosmic reionization is its separation from the much brighter foreground emission. Such separation relies on the different spectral properties of the ...
Probing beyond-Horndeski gravity on ultra-large scales
(2020)
The beyond-Horndeski gravity has recently been reformulated in the dark energy
paradigm — which has been dubbed, Unified Dark Energy (UDE). The evolution equations
for the given UDE appear to correspond to a non-conservative ...
