A unique, ring-like radio source with quadrilateral structure detected with machine learning
(Oxford University Press, 2023)
We report the discovery of a unique object in the MeerKAT Galaxy Cluster Le gacy Survey (MGCLS) using the machine learning anomaly detection framework ASTRONOMALY. This strange, ring-like source is 30 from the MGCLS field ...
Cosmic sands: the origin of dusty, star-forming galaxies in the epoch of reionization
(The astrophysical journal, 2023)
We present the Cosmic Sands suite of cosmological zoom-in simulations based on the simba galaxy formation model in order to study the buildup of the first massive and dusty galaxies in the early universe. Residing in the ...
Characterizing line-of-sight variability of polarized dust emission with future cmb experiments
(Oxford University Press, 2023)
While Galactic dust emission is often accounted for in cosmic microwave background (CMB) analyses by fitting a two-parameter modified blackbody (MBB) model in each pixel, typically a number of such clouds are found along ...
Infuence of Synthesis Method on Structural, Morphological, Magnetic, and Antimicrobial Properties of Fe‑Ag Nanoparticles
(Springer, 2023)
This contribution reports on the development of two versatile and efcient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition potential ...
The total rest-frame UV luminosity function from 3 < z < 5: a simultaneous study of agn and galaxies from −28 < MUV < −16
(Oxford University Press, 2023)
We present measurements of the rest-frame ultraviolet luminosity function (LF) at redshifts z = 3, z = 4, and z = 5, using 96894, 38655, and 7571 sources, respectively, to map the transition between active galactic nuclei ...
The h i in ring galaxies survey (h i -rings) - effects of the bar on the h i gas in ring galaxies
(Cambridge University Press, 2023)
We present a new high-resolution neutral atomic hydrogen (Hi) survey of ring galaxies using the Australia Telescope Compact Array (ATCA). We target a sample of 24 ring galaxies from the Buta (1995) Southern Ring Galaxy ...
MIGHTEE-H I: the first MeerKAT H I mass function from an untargeted interferometric survey
(Oxford University Press, 2023)
We present the first measurement of the H I mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MeerKAT International GigaHertz Tiered Extragalactic Exploration (MIGHTEE) Survey Early ...
Beta decay along the n=z line and its relevance in rp-process and x-ray bursts
(EDP Sciences, 2023)
Nucleosynthesis in Type I X-ray bursts (XRB) proceeds eventually through the rp-process near the proton drip-line. Several N=Z nuclei act as waiting points in the reaction network chain. Astrophysical calculations of XRB ...
The trapum l-band survey for pulsars in fermi-lat gamma-ray sources
(Oxford University Press, 2023)
More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but hundreds of pulsar-like sources remain unidentified. Here, we ...
Multipole expansion for 21 cm intensity mapping power spectrum: forecasted cosmological parameters estimation for the ska observatory
(Oxford University Press, 2023)
The measurement of the large-scale distribution of neutral hydrogen in the late Universe, obtained with radio telescopes through the hydrogen 21 cm line emission, has the potential to become a key cosmological probe in the ...
