A snapshot of the oldest AGN feedback phases
M. Brienza, T. W. Shimwell, F. de Gasperin +19
Active Galactic Nuclei (AGN) inject large amounts of energy into their host galaxies and surrounding environment, shaping their properties and evolution. In particular, AGN jets in…
Detection of coherent low-frequency radio bursts from weak-line TTauri stars
A. Feeney-Johansson, S. J. D. Purser, T. P. Ray +7
In recent years, thanks to new facilities such as LOFAR capable of sensitive observations, much work has been done on the detection of stellar radio emission at low frequencies. Su…
A Galactic survey of radio jets from massive protostars
S. J. D. Purser, S. L. Lumsden, M. G. Hoare +1
In conjunction with a previous southern-hemisphere work, we present the largest radio survey of jets from massive protostars to date with high-resolution, ($\sim 0.04^{\prime\prime…
A Multi-Epoch Study of Radio Continuum Emission from MassiveProtostars
W. O. Obonyo, S. L. Lumsden, M. G. Hoare +2
We report the results of the Jansky Very Large Array (JVLA) observation of five massive protostars at 6 and 22.2 GHz. The aim of the study was to compare their current fluxes and p…
The first detection of a low-frequency turnover in nonthermal emission from the jet of a young star
Anton Feeney-Johansson, Simon J. D. Purser, Tom P. Ray +4
Radio emission in jets from young stellar objects (YSOs) in the form of nonthermal emission has been seen toward several YSOs. Thought to be synchrotron emission from strong shocks…
Measuring the ionisation fraction in a jet from a massive protostar
R. Fedriani, A. Caratti o Garatti, S. J. D. Purser +7
It is important to determine if massive stars form via disc accretion, like their low-mass counterparts. Theory and observation indicate that protostellar jets are a natural conseq…
