Designing an optimal LSST deep drilling program for cosmology with type Ia supernovae
(American Astronomical Society, 2023)
The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) is forecast to collect a large sample of
Type Ia supernovae (SNe Ia) expected to be instrumental in unveiling the nature of dark energy. The feat, ...
Short-period pulsating hot-subdwarf stars observed by TESS: I. Southern ecliptic hemisphere
(EDP Sciences, 2023)
We present results of a Transiting Exoplanet Survey Satellite (TESS) search for short-period pulsations in compact stellar objects
observed in years 1 and 3 of the TESS mission, during which the southern ecliptic hemisphere ...
Quijote-png: Simulations of primordial non-gaussianity and the information content of the matter field power spectrum and bispectrum
(IOP Publishing, 2023)
Primordial non-Gaussianity (PNG) is one of the most powerful probes of the early universe, and measurements of
the large-scale structure of the universe have the potential to transform our understanding of this area. ...
Quijote-png: The information content of the halo power spectrum and bispectrum
(IOP Publishing, 2023)
We investigate how much can be learnt about four types of primordial non-Gaussianity (PNG) from small-scale
measurements of the halo field. Using the QUIJOTE-PNG simulations, we quantify the information content
accessible ...
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. ...
H I intensity mapping with MeerKAT: Power spectrum detection in cross-correlation with WiggleZ galaxies
(Oxford University Press, 2023)
We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a 7.7σ detection of the cross-correlation power spectrum, the amplitude of which ...
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 ...
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 ...
