Optimization of the observing cadence for the Rubin observatory legacy survey of space and time: A pioneering process of community-focused experimental design
(IOP Publishing, 2022)
Vera C. Rubin Observatory is a ground-based astronomical facility under construction, a joint project of the
National Science Foundation and the U.S. Department of Energy, designed to conduct a multipurpose 10 yr ...
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 ...
Practical galaxy morphology tools from deep supervised representation learning
(Oxford University Press, 2022)
Astronomers have typically set out to solve supervised machine learning problems by creating their own representations
from scratch. We show that deep learning models trained to answer every Galaxy Zoo DECaLS question ...
MIGHTEE-Hi: The relation between the Hi gas in galaxies and the cosmic web
(Oxford University Press, 2022)
We study the 3D axis of rotation (3D spin) of 77 Hi galaxies from the MIGHTEE-Hi Early Science observations, and its
relation to the filaments of the cosmic web. For this Hi-selected sample, the alignment between the spin ...
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) ...
The physical properties of star-forming galaxies with strong [oiii]lines at z=3.25
(IOP Publishing, 2022)
We present an analysis of physical properties of 34 [O III] emission-line galaxies (ELGs) at z = 3.254 ± 0.029 in
the Extended Chandra Deep Field South (ECDFS). These ELGs are selected from deep narrow H2S(1) and broad
Ks ...
The star formation rates of QSOs
(Royal Astronomical Society, 2022)
We examine the far-IR properties of a sample of 5391 optically selected QSOs in the
0.5 < z < 2.65 redshift range down to log [νLν,2500(erg/s)] > 44.7, using SPIRE data
from Herschel-ATLAS. We split the sample in a grid ...
Breaking baryon-cosmology degeneracy with the electron density power spectrum
(IOP Publishing, 2022)
Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics
that are robust against these uncertainties, or ...
The circumgalactic medium from the camels simulations: Forecasting constraints on feedback processes from future Sunyaev–Zeldovich observations
(IOP Publishing, 2022)
It is important to understand the cycle of baryons through the circumgalactic medium (CGM) in the context of
galaxy formation and evolution. In this study, we forecast constraints on the feedback processes heating the ...
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 ...
