A real time processing system for big data in astronomy: Applications to Hera
(Elsevier, 2021)
As current- and next-generation astronomical instruments come online, they will generate an unprecedented deluge of data. Analyzing these data in real time presents unique conceptual and computational
challenges, and their ...
A deep radio view of the evolution of the cosmic star formation rate density from a stellar-mass-selected sample in VLA-COSMOS
(Royal Astronomical Society, 2022)
We present the 1.4 GHz radio luminosity functions (RLFs) of galaxies in the Cosmic Evolution Survey (COSMOS) field, measured above and below the 5σ detection threshold, using a Bayesian model-fitting technique. The radio ...
COSMOS2020: A panchromatic view of the universe to z ∼ 10 from two complementary catalogs
(University of the Western Cape, 2022)
The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public catalog in 2015, a wealth of new imaging and spectroscopic data have been collected in the COSMOS field. This ...
Hi global scaling relations in the wise-whisp survey
(Oxford University Press, 2021)
We present the global scaling relations between the neutral atomic hydrogen gas, the stellar disk and the star forming
disk in a sample of 228 nearby galaxies that are both spatially and spectrally resolved in HI line ...
Big data research infrastructure collaboration toward the SKA (BRICSKA)
(Academia Brasileira de Ciencias, 2021)
Astronomy is entering an era of mega-data that will render conventional
research methods as well as data and visual analytics tools ineffective. The Square
Kilometre Array (SKA) drives one of the most significant big ...
Pks 1830-211: oh and hi at z = 0.89 and the first meerkat uhf spectrum
(EDP Sciences, 2021)
The Large Survey Project (LSP) "MeerKAT Absorption Line Survey"(MALS) is a blind H I 21 cm and OH 18 cm absorption line survey in the L- and UHF-bands, primarily designed to better determine the occurrence of atomic and ...
High-precision half-life determination of 14O via direct β counting
(Springer, 2022)
The half-life of the superallowed Fermi β+ emitter 14O was determined to high precision via a direct
β counting experiment performed at the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. The result,
T1/2(
14O) ...
Pulsar scintillation studies with LOFAR I. The census
(Hans Publishers, 2022)
Interstellar scintillation (ISS) of pulsar emission can be used both as a probe of the ionized interstellar medium (IISM) and
cause corruptions in pulsar timing experiments. Of particular interest are so-called scintillation ...
Trapum discovery of 13 new pulsars in ngc 1851 using meerkat
(Hans Publishers, 2022)
We report the discovery of 13 new pulsars in the globular cluster NGC 1851 by the TRAPUM Large Survey Project using the
MeerKAT radio telescope. The discoveries consist of six isolated millisecond pulsars (MSPs) and seven ...
Consequences of using a smooth cosmic distance in a lumpy Universe. I.
(American Physical Society, 2022)
How do we appropriately fit a model based on an idealised Friedmann-Lemaˆıtre Robertson-Walker
spacetime to observations made from a single location in a lumpy Universe? We address this question
for surveys that measure ...
