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…
A low-frequency view of mixed-morphology supernova remnant VRO 42.05.01, and its neighbourhood
M. Arias, J. Vink, M. Iacobelli +7
Mixed-morphology supernova remnants (MM SNRs) are a mysterious class of objects that display thermal X-ray emission within their radio shell. They are an older class of SNRs, and a…
Cooling in the X-ray halo of the rotating, massive early-type galaxy NGC 7049
A. Juráňová, N. Werner, M. Gaspari +9
The relative importance of the physical processes shaping the thermodynamics of the hot gas permeating rotating, massive early-type galaxies is expected to be different from that i…
A Galaxy-Scale Fountain of Cold Molecular Gas Pumped by a Black Hole
Grant R. Tremblay, Françoise Combes, J. B. Raymond Oonk +36
We present ALMA and MUSE observations of the Brightest Cluster Galaxy in Abell 2597, a nearby (z=0.0821) cool core cluster of galaxies. The data map the kinematics of a three billi…
Low-Frequency Radio Absorption in Cassiopeia A
M. Arias, J. Vink, F. de Gasperin +3
Cassiopeia A is one of the best-studied supernova remnants. Its shocked ejecta emits brightly in radio and X-rays. Its unshocked ejecta can be studied through infrared emission, th…
