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, ...
Dusty starbursts masquerading as ultra-high redshift galaxies in jwst ceers observations
(American Astronomical Society, 2023)
Lyman-break galaxy (LBG) candidates at z 10 are rapidly being identified in James Webb Space Telescope
(JWST)/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of restframe UV ...
An∼600 pc view of the strongly lensed, massive main-sequence galaxy j0901: A baryon-dominated, thick turbulent rotating disk with a clumpy cold gas ring at z=2.259
(American Astronomical Society, 2023)
We present a high-resolution kinematic study of the massive main-sequence star-forming galaxy (SFG)
SDSS J090122.37+181432.3 (J0901) at z = 2.259, using ∼0 36 Atacama Large Millimeter/submillimeter Array
CO(3–2) and ∼0 ...
Global simulations of multi-frequency hf signal absorption for direct observation of middle atmosphere temperature and composition
(Wiley, 2023)
This paper presents the first numerical study on a new concept for the direct measurement of
D-region absorption in the high-frequency (HF) band. Numerical simulations based on the Appleton-Hartree
and Garrett equations ...
Revisiting the [C ii]158𝝁��m line-intensity mapping power spectrum from the EoR using non-uniform line-luminosity scatter
(Oxford University Press, 2023)
Detecting the line-intensity mapping (LIM) signal from the galaxies of the Epoch of Reionization is an emerging tool to constrain
their role in reionization. Ongoing and upcoming experiments target the signal fluctuations ...
The MeerKAT pulsar timing array: First data release
(Oxford University Press, 2022)
We present the first 2.5 years of data from the MeerKAT Pulsar Timing Array (MPTA), part of MeerTime, a MeerKAT Large
Survey Project. The MPTA aims to precisely measure pulse arrival times from an ensemble of 88 pulsars ...
Interferometric H I intensity mapping: perturbation theory predictions and foreground removal effects
(Oxford University Press, 2023)
We provide perturbation theory predictions for the H I intensity mapping power spectrum multipoles using the Effective Field
Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. ...
A search for variable subdwarf B stars in TESS Full Frame Images III. An update on variable targets in both ecliptic hemispheres – contamination analysis and new sdB pulsators
(Oxford University Press, 2023)
We present an update on the variable star survey performed on the TESS 30 min Full Frame
Image (FFI) data reported by our first two papers in this series. This update includes a
contamination analysis in order to identify ...
The LOFAR Tied-Array All-Sky Survey: Timing of 35 radio pulsars and an overview of the properties of the LOFAR pulsar discoveries
(Astronomy& Astrophysics, 2023)
The LOFAR Tied-Array All-Sky Survey (LOTAAS) is the most sensitive untargeted radio pulsar survey performed at low radio frequencies (119−151 MHz) to date and has discovered 76 new radio pulsars, including the 23.5-s pulsar ...
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 ...
