A quantitative in-depth analysis of the prototype sdB+BD system SDSS J08205+0008 revisited in the Gaia era
(Oxford University Press, 2021)
Subdwarf B stars are core-helium-burning stars located on the extreme horizontal branch (EHB). Extensive mass loss on the red giant branch is necessary to form them. It has been proposed that substellar companions could ...
The origin and evolution of Lyα blobs in cosmological galaxy formation simulations
(IOP Publishing Ltd, 2021)
High-redshift Lyα blobs (LABs) are an enigmatic class of objects that have been the subject of numerous observational and theoretical investigations. It is of particular interest to determine the dominant power sources for ...
Enhanced electrochemical glucose sensing performance of CuO:NiO mixed oxides thin film by plasma assisted nitrogen doping
(Elsevier, 2021)
In this study plasma-assisted nitrogen doping of a CuO–NiO mixed oxide thin film was presented. The as prepared film was also applied as a glucose sensor. The nitrogen species generated during plasma ignition resulted in ...
H i intensity mapping with MeerKAT: 1/f noise analysis
(Oxford University Press, 2021)
The nature of the time correlated noise component (the 1/f noise) of single dish radio telescopes is critical to the detectability of the H i signal in intensity mapping experiments. In this paper, we present the 1/f noise ...
The infrared-radio correlation of star-forming galaxies is strongly M∗-dependent but nearly redshift-invariant since z ∼4
(EDP Sciences, 2021)
Over the past decade, several works have used the ratio between total (rest 8-1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (qIR), often referred to as the infrared-radio correlation (IRRC), ...
MIGHTEE: Are giant radio galaxies more common than we thought?
(Oxford University Press, 2021)
We report the discovery of two new giant radio galaxies (GRGs) using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. Both GRGs were found within a ∼}1\, deg2 region inside the COSMOS field. ...
Ion beam induced modification and nanostructures formation in thin SiC/Pd films on c-Si substrate
(Elsevier, 2021)
Ion beam induced modification of thin metallic films is an emerging approach to grow metallic nanoparticles controllably. Modification of thin solid films is helpful in fabricating arrays of nanoscale particles for electronic ...
An ALMA/NOEMA survey of the molecular gas properties of high-redshift star-forming galaxies
(Oxford University Press, 2021)
We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We detect 12CO (Jup = 2-5) emission lines in 50 sources, and [C ...
Pulsars with NenuFAR: Backend and pipelines
(EDP Sciences, 2021)
Context. NenuFAR (New extension in Nançay upgrading LOFAR) is a new radio telescope developed and built on the site of the Nançay Radio Observatory. It is designed to observe the largely unexplored frequency window from ...
Close-up view of a luminous star-forming galaxy at z = 2.95
(EDP Sciences, 2021)
Exploiting the sensitivity of the IRAM NOrthern Extended Millimeter Array (NOEMA) and its ability to process large instantaneous bandwidths, we have studied the morphology and other properties of the molecular gas and dust ...
