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 ...
Simulations of primary beam effects on the cosmic bispectrum phase observed with the Hydrogen Epoch of Reionization Array
(Royal Astronomical Society, 2022)
The 21 cm transition from neutral hydrogen promises to be the best observational probe of the epoch of reionization (EoR). The main difficulty in measuring the 21 cm signal is the presence of bright foregrounds that require ...
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) ...
A comprehensive study of modulation effects on CMB polarization
(Springer, 2022)
The Cosmic Microwave Background is characterized by temperature and linear polar ization fields. Dipole modulation in the temperature field has been extensively studied
in the context of hemispherical power asymmetry. In ...
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 ...
Solar-Cycle Variability Results fromthe Solar Radiation and Climate Experiment (SORCE) Mission
(Springer, 2022)
The Solar Radiation and Climate Experiment (SORCE) was a NASA mission that operated
from 2003 to 2020 to provide key climate-monitoring measurements of total solar irradiance
(TSI) and solar spectral irradiance (SSI). ...
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 ...
First Observations of E‐Region Near Range Echoes Partially Modulated by F‐Region Traveling Ionospheric Disturbances Observed by the Same SuperDARN HF Radar
(American Geophysical Union, 2022)
We present the first observations from SuperDARN HF radar data of E‐region Near Range Echoes (NREs) whose amplitudes are partially modulated by Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) propagating in the ...
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 ...
