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…
LOFAR VLBI Studies at 55 MHz of 4C 43.15, a z=2.4 Radio Galaxy
Leah K. Morabito, Adam T. Deller, Huub Röttgering +8
The correlation between radio spectral index and redshift has been exploited to discover high redshift radio galaxies, but its underlying cause is unclear. It is crucial to charact…
Cold, clumpy accretion onto an active supermassive black hole
Grant R. Tremblay, J. B. Raymond Oonk, Françoise Combes +22
Supermassive black holes in galaxy centres can grow by the accretion of gas, liberating energy that might regulate star formation on galaxy-wide scales. The nature of the gaseous f…
Embedded star formation in the extended narrow line region of Centaurus A: extreme mixing observed by MUSE
F. Santoro, J. B. R. Oonk, R. Morganti +2
We present a detailed study of the complex ionization structure in a small (~250 pc) extended narrow line region (ENLR) cloud near Centaurus A using the Multi Unit Spectroscopic Ex…
ALMA observations of cold molecular gas filaments trailing rising radio bubbles in PKS0745-191
H. R. Russell, B. R. McNamara, A. C. Fabian +16
We present ALMA observations of the CO(1-0) and CO(3-2) line emission tracing filaments of cold molecular gas in the central galaxy of the cluster PKS0745-191. The total molecular…
LOFAR detections of low-frequency radio recombination lines towards Cassiopeia A
Ashish Asgekar, J. B. R. Oonk, S. Yatawatta +89
Cassiopeia A was observed using the Low-Band Antennas of the LOw Frequency ARray (LOFAR) with high spectral resolution. This allowed a search for radio recombination lines (RRLs) a…
