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 ...
Measuring the HI mass function below the detection threshold
(Royal Astronomical Society, 2020)
We present a Bayesian stacking technique to directly measure the H I mass function (HIMF) and its evolution with redshift using galaxies formally below the nominal detection threshold. We generate galaxy samples over several ...
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 ...
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 ...
Semi-analytic forecasts for Roman – the beginning of a new era of deep-wide galaxy surveys
(Oxford University Press, 2023)
The Nancy Grace Roman Space Telescope, NASA’s next flagship observatory, will redefine deep-field galaxy survey with a field of view two orders of magnitude larger than
Hubble and an angular resolution of matching quality. ...
The physical nature of circumgalactic medium absorbers in SIMBA
(Oxford University Press, 2023)
We study the nature of the low-redshift circumgalactic medium (CGM) in the SIMBA cosmological simulations as traced by
ultraviolet absorption lines around galaxies in bins of stellar mass (M > 1010M) for star-forming, ...
Galaxy and Mass Assembly (GAMA): Mid-infrared properties as tracers of galaxy environment
(EDP Sciences, 2023)
We investigate how different mid-infrared (mid-IR) properties of galaxies are correlated with the environment in which the
galaxies are located. For this purpose, we first study the dependence of galaxy clustering on the ...
Probing Cosmology beyond ΛCDM using the SKA
(Indian Academy of Sciences, 2023)
The cosmological principle states that the Universe is statistically homogeneous and isotropic at
large distance scales. Currently, there exist many observations which indicate a departure from this principle.
It has ...
Ceers key paper. I. An early look into the first 500myr of galaxy formation with jwst
(American Astronomical Society, 2023)
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release
Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ∼ 0.5 to >10
using ...
