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…
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.,…
Are starburst galaxies a common source of high energy neutrinos and cosmic rays?
Cecilia Lunardini, Gregory S. Vance, Kimberly L. Emig +1
A recent analysis of cosmic ray air showers observed at the Pierre Auger Observatory indicates that nearby starburst galaxies (SBGs) might be the cause of ~10% of the Ultra-High-En…
The first detection of radio recombination lines at cosmological distances
K. L. Emig, P. Salas, F. de Gasperin +4
Recombination lines involving high principal quantum numbers populate the radio spectrum in large numbers. Low-frequency (<1 GHz) observations of radio recombination lines (RRLs) p…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
LOFAR observations of decameter carbon radio recombination lines towards Cassiopeia A
P. Salas, J. B. R. Oonk, R. J. van Weeren +6
We present a study of carbon radio recombination lines towards Cassiopeia A using LOFAR observations in the frequency range 10-33 MHz. Individual carbon lines are detected in a…
