Mightee: Deep 1.4 ghz source counts and the sky temperature contribution of star-forming galaxies and active galactic nuclei
(Oxford University Press, 2023)
We present deep 1.4 GHz source counts from ∼5 deg2 of the continuum Early Science data release of the MeerKAT International Gigahertz Tiered Extragalactic Exploration survey down to S1.4GHz ∼15 μ
Jy. Using observations ...
Hot white dwarfs and pre-white dwarfs discovered with SALT
(Oxford University Press, 2023)
The Southern African Large Telescope survey of helium-rich hot subdwarfs aims to explore evolutionary pathways among groups of highly evolved stars. The selection criteria mean that several hot white dwarfs and related ...
Collective rotational bands at low excitation energy in 186Os: Vibrational and rotational degrees of freedom
(American Physical Society, 2022)
Collective structures in 186Os have been investigated through the 186W(4He, 4n) 186Os reaction, at a beam
energy of 48 MeV. The low-lying bands built on the excited 0+
2 , 2+
2 , and 4+
3 states have been extended up ...
Redshift evolution of galaxy group X-ray properties in the SIMBA simulations
(Oxford University Press, 2023)
We examine the evolution of intragroup gas rest-frame X-ray scaling relations for group-sized haloes (M500 = 1012.3–1015 M)
in the SIMBA galaxy formation simulation. X-ray luminosity LX versus M500 shows increasing deviation ...
A new technique to isolate kinematically anomalous gas in HI data cubes
(Oxford University Press, 2023)
H I line observations of nearby galaxies often reveal the presence of extraplanar and/or kinematically anomalous gas that deviates from the general circular flow. In this work, we study the dependence of kinematically ...
The lofar two-metre sky survey: Deep fields data release 1. V. Survey description, source classifications, and host galaxy properties
(Oxford University Press, 2023)
Source classifications, stellar masses, and star-formation rates are presented for ≈80 000 radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey (LoTSS) Deep Fields, which represents the ...
The fore ground transfer function for H I intensity mapping signal reconstruction: MeerKLASS and precision cosmology applications
(Oxford University Press, 2023)
Blind cleaning methods are currently the preferred strategy for handling foreground contamination in single-dish H I intensity mapping surv e ys. Despite the increasing sophistication of blind techniques, some signal loss ...
Hydra ii: Characterisation of Aegean, Caesar, profound, pybdsf, and selavy source finders
(Cambridge University Press, 2023)
We present a comparison between the performance of a selection of source finders using a new software
tool called Hydra. The companion paper, Paper I, introduced the Hydra tool and demonstrated its
performance using ...
Hydra I: An extensible multi-source-finder comparison and cataloguing tool
(Cambridge University Press, 2023)
The latest generation of radio surveys are now producing sky survey images containing many millions of radio sources. In this context it is highly desirable to understand the performance of radio image source finder (SF) ...
The bright extragalactic ALMA redshift survey (BEARS) – II. Millimetre photometry of gravitational lens candidates
(Oxford University Press, 2023)
We present 101- and 151-GHz ALMA continuum images for 85 fields selected from Herschel observations that have 500-μm flux densities >80 mJy and 250–500-μm colours consistent with z > 2, most of which are expected to be ...
