The lofar two-meter sky survey: Deep fields data release 1: II. The elais-n1 lofar deep field
(EDP Sciences, 2021)
The LOFAR Two-metre Sky Survey (LoTSS) will cover the full northern sky and, additionally, aims to observe the LoTSS deep fields to a noise level of ? 10 μJy beam-1 over several tens of square degrees in areas that have ...
The LOFAR Two-metre sky survey deep fields: The star-formation rate-radio luminosity relation at low frequencies
(EDP Sciences, 2021)
In this paper, we investigate the relationship between 150 MHz luminosity and the star-formation rate - the SFR-L150 MHz relation - using 150 MHz measurements for a near-infrared selected sample of 118 517 z < 1 galaxies. ...
The lofar two-meter sky survey: Deep fields data release 1: IV. Photometric redshifts and stellar masses
(EDP Sciences, 2021)
The Low Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) is a sensitive, high-resolution 120-168 MHz survey split across multiple tiers over the northern sky. The first LoTSS Deep Fields data release consists of deep ...
High Molecular-gas to Dust Mass Ratios Predicted in Most Quiescent Galaxies
(American Astronomical Society, 2021)
Observations of cold molecular gas reservoirs are critical for understanding the shutdown of star formation in massive galaxies. While dust continuum is an efficient and affordable tracer, this method relies upon the ...
A new auroral phenomenon, the anti-black aurora
(Nature, 2021)
Black auroras are small-scale features embedded in the diffuse background aurora, typically occurring post-substorm after magnetic midnight and with an eastward drift imposed. Black auroras show a significant reduction in ...
MIGHTEE-HI: discovery of an HI-rich galaxy group at z = 0.044 with MeerKAT
(Monthly Notices of the Royal Astronomical Society, 2021)
We present the serendipitous discovery of a galaxy group in the XMM-LSS field with MIGHTEE Early Science observations. 20
galaxies are detected in HI in this z ∼ 0.044 group, with a 3σ column density sensitivity of NHI = ...
Reflectivity of VUV-sensitive silicon photomultipliers in liquid Xenon
(IOP Publishing, 2021)
Silicon photomultipliers are regarded as a very promising technology for nextgeneration,
cutting-edge detectors for low-background experiments in particle physics. This work
presents systematic reflectivity studies of ...
Observing relativistic features in large-scale structure surveys - I. Multipoles of the power spectrum
(Oxford University Press, 2021)
Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation and the possibility of constraining novel ...
Mixed-halide perovskites solar cells through PbICl and PbCl2 precursor films by sequential chemical vapor deposition
(Elsevier, 2021)
Mixed halide perovskites with chlorine (Cl) content have received significant interest due to better charge transport properties and longer diffusion length compared to pure iodine-based perovskites. The superior properties ...
Extremely deep 150 MHz source counts from the LoTSS deep fields
(EDP Sciences, 2021)
With the advent of new generation low-frequency telescopes, such as the LOw Frequency ARray (LOFAR), and improved calibration techniques, we have now started to unveil the subgigahertz radio sky with unprecedented depth ...
