Realising the LOFAR Two-Metre Sky Survey -- using the supercomputer JUWELS at the Forschungszentrum Jülich
A. Drabent, M. Hoeft, A. P. Mechev +10
The new generation of high-resolution broad-band radio telescopes, like the Low Frequency Array (LOFAR), produces, depending on the level of compression, between 1 to 10 TB of data…
Searching for the largest bound atoms in space
K. L. Emig, P. Salas, F. de Gasperin +5
(abridged) Radio recombination lines (RRLs) at frequencies < 250 MHz trace the cold, diffuse phase of the ISM. Next generation low frequency interferometers, such as LOFAR, MWA…
Constraining cold accretion onto supermassive black holes: molecular gas in the cores of eight brightest cluster galaxies revealed by joint CO and CN absorption
Tom Rose, A. C. Edge, F. Combes +18
To advance our understanding of the fuelling and feedback processes which power the Universe's most massive black holes, we require a significant increase in our knowledge of the m…
Spectroscopy with the Engineering Development Array: cold H at 63 MHz towards the Galactic Centre
J. B. R. Oonk, E. L. Alexander, J. W. Broderick +2
The Engineering Development Array (EDA) is a single test station for Square Kilometre Array (SKA) precursor technology. We have used the EDA to detect low-frequency radio recombina…
Efficient computation of collisional -mixing rate coefficients in astrophysical plasmas
D. Vrinceanu, R. Onofrio, J. B. R. Oonk +2
We present analytical expressions for direct evaluation of -mixing rate coefficients in proton-excited hydrogen atom collisions and describe a software package for efficient…
Carbon radio recombination lines from gigahertz to megahertz frequencies towards Orion A
P. Salas, J. B. R. Oonk, K. L. Emig +4
Context. The combined use of carbon radio recombination lines (CRRLs) and the 158 m-[CII] line is a powerful tool for the study of the energetics and physical conditions (e.g.,…
