Constraining the intergalactic medium at z ≈ 9.1 using LOFAR Epoch of Reionization observations
(Advance access publications, 2020)
We derive constraints on the thermal and ionization states of the intergalactic medium (IGM) at redshift ≈ 9.1 using new upper
limits on the 21-cm power spectrum measured by the LOFAR radio telescope and a prior on the ...
Direct parameter inference from global EoR signal with Bayesian statistics
(Oxford University Press, 2020)
In the observation of sky-averaged HI signal from Epoch of Reionization (EoR), model parameter inference can be a computation-intensive work, which makes it hard to perform a direct one-stage model parameter inference by ...
The optically selected 1.4-GHz quasar luminosity function below 1 mJy
(Oxford University Press, 2020)
We present the radio luminosity function (RLF) of optically selected quasars below 1 mJy, constructed by applying a Bayesian-fitting stacking technique to objects well below the nominal radio flux density limit. We test ...
Possible periodic activity in the repeating FRB 121102
(Oxford University Press, 2020)
The discovery that at least some Fast Radio Bursts (FRBs) repeat has ruled out cataclysmic events as the progenitors of these particular bursts. FRB 121102 is the most well-studied repeating FRB but despite extensive ...
Fundamental physics with the square kilometre array
(Cambridge University Press, 2020)
The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with
an order of magnitude greater sensitivity and survey speed than any current radio ...
WALLABY – an SKA Pathfinder H I survey
(Springer Nature, 2020)
The Widefield ASKAP L-band Legacy All-sky
Blind surveY (WALLABY) is a next-generation survey
of neutral hydrogen (H I) in the Local Universe. It uses
the widefield, high-resolution capability of the Australian
Square ...
Evidence from the Vredefort Granophyre Dikes points to crustal relaxation following basin-size impact cratering
(Academic Press Inc., 2021-11-24)
The timescale of the modification stage of basin-sized impact structures is not well understood. Owing to ca. 10
km of erosion since its formation, the Vredefort impact structure, South Africa, is an ideal testing ground ...
The contribution of discrete sources to the sky temperature at 144 MHz
(EDP Sciences, 2021)
In recent years, the level of the extragalactic radio background has become a point of considerable interest, with some lines of argument pointing to an entirely new cosmological synchrotron background. The contribution ...
Sharing for science: High-resolution trophic interactions revealed rapidly by social media
(PeerJ, 2020)
Discrete, ephemeral natural phenomena with low spatial or temporal predictability are incredibly challenging to study systematically. In ecology, species interactions, which constitute the functional backbone of ecological ...
Review: Acid mine drainage (AMD) in abandoned coal mines of Shanxi, China
(MDPI, 2020)
Excessive exploitation and massive coal mine closures have brought about extensive goafs in Shanxi where 8780 coal mines have been abandoned in the last 20 years. Acid mine drainage (AMD) poses severe environmental impact ...
