WALLABY Early Science -- IV. ASKAP HI imaging of the nearby galaxy IC 5201
D. Kleiner, B. S. Koribalski, P. Serra +19
We present a Wide-field ASKAP L-Band Legacy All-sky Blind surveY (WALLABY) study of the nearby ( = 915 km s) spiral galaxy IC 5201 using the Australian Square K…
The Rise of the s-Process in the Galaxy
J. Simmerer, C. Sneden, J. J. Cowan +3
From newly-obtained high-resolution, high signal-to-noise ratio spectra the abundances of the elements La and Eu have been determined over the stellar metallicity range -3<[Fe/H]<+…
Analysis of four-wave mixing of high-power lasers for the detection of elastic photon-photon scattering
J. Lundin, M. Marklund, E. Lundstrom +5
We derive expressions for the coupling coefficients for electromagnetic four-wave mixing in the non-linear quantum vacuum. An experimental setup for detection of elastic photon-pho…
Femtosecond temperature measurements of laser-shocked copper deduced from the intensity of the x-ray thermal diffuse scattering
J. S. Wark, D. J. Peake, T. Stevens +122
We present 50-fs, single-shot measurements of the x-ray thermal diffuse scattering (TDS) from copper foils that have been shocked via nanosecond laser-ablation up to pressures abov…
Laboratory soft x-ray emission due to the Hawking-Unruh effect?
G. Brodin, M. Marklund, R. Bingham +2
The structure of spacetime, quantum field theory, and thermodynamics are all connected through the concepts of the Hawking and Unruh temperatures. The possible detection of the rel…
MIGHTEE: multi-wavelength counterparts in the COSMOS field
I. H. Whittam, M. Prescott, C. L. Hale +26
In this paper we combine the Early Science radio continuum data from the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Survey, with optical and near-infrared…
AGN behind the SMC selected from radio and X-ray surveys
R. Sturm, D. DraÅ¡koviÄ, M. D. FilipoviÄ +8
The XMM-Newton survey of the Small Magellanic Cloud (SMC) revealed 3053 X-ray sources with the majority expected to be active galactic nuclei (AGN) behind the SMC. However, the hig…
Using high-power lasers for detection of elastic photon-photon scattering
E. Lundstrom, G. Brodin, J. Lundin +5
The properties of four-wave interaction via the nonlinear quantum vacuum is investigated. The effect of the quantum vacuum is to generate photons with new frequencies and wave vect…
X-ray thermal diffuse scattering as a texture-robust temperature diagnostic for dynamically compressed solids
P. G. Heighway, D. J. Peake, T. Stevens +119
We present a model of x-ray thermal diffuse scattering (TDS) from a cubic polycrystal with an arbitrary crystallographic texture, based on the classic approach of Warren. We compar…
