Can galaxy growth be sustained through HI-rich minor mergers?
M. D. Lehnert, W. van Driel, R. Minchin
Local galaxies with specific star-formation rates (star-formation rate per unit mass; sSFR~0.2-10/Gyr) as high as distant galaxies (z~1-3), are very rich in HI. Those with low stel…
Extragalactic large-scale structures in the northern Zone of Avoidance
M Ramatsoku, R C Kraan-Korteweg, A C Schröder +1
We used the Nançay Radio Telescope (NRT) to measure the 21 cm line emission of near-infrared bright galaxies in the northern Zone of Avoidance (ZoA) without previous redshift deter…
Subarcsecond international LOFAR radio images of the M82 nucleus at 118 MHz and 154 MHz
E. Varenius, J. E. Conway, I. Martí-Vidal +25
The nuclear starburst in the nearby galaxy M82 provides an excellent laboratory for understanding the physics of star formation. This galaxy has been extensively observed in the pa…
Discovery of Carbon Radio Recombination Lines in M82
Leah K. Morabito, J. B. R. Oonk, Francisco Salgado +30
Carbon radio recombination lines (RRLs) at low frequencies (<=500 MHz) trace the cold, diffuse phase of the interstellar medium, which is otherwise difficult to observe. We present…
