Pulsars identified in the LOFAR Two-metre Sky Survey at 144 MHz
G. A. C. Rijkers, C. G. Bassa, J. R. Callingham +1
We present the astrometric identification of 80 known radio pulsars as unresolved continuum sources detected at 144 MHz in the second data release of the LOFAR Two-metre Sky Survey…
Sporadic radio pulses from a white dwarf binary at the orbital period
I. de Ruiter, K. M. Rajwade, C. G. Bassa +14
Recent observations have revealed rare, previously unknown flashes of cosmic radio waves lasting from milliseconds to minutes, and with periodicity of minutes to an hour. These tra…
Probing particle acceleration in Abell 2256: from to 16 MHz to gamma rays
E. Osinga, R. J. van Weeren, G. Brunetti +9
Merging galaxy clusters often host spectacular diffuse radio synchrotron sources. These sources can be explained by a non-thermal pool of relativistic electrons accelerated by shoc…
Searching for pulsars associated with polarised point sources using LOFAR: Initial discoveries from the TULIPP project
C. Sobey, C. G. Bassa, S. P. O'Sullivan +15
Discovering radio pulsars, particularly millisecond pulsars (MSPs), is important for a range of astrophysical applications, such as testing theories of gravity or probing the magne…
New candidate radio supernova remnants detected in the GLEAM survey over ,
Natasha Hurley-Walker, Miroslav D. Filipovic, Bryan M. Gaensler +18
We have detected 27 new supernova remnants (SNRs) using a new data release of the GLEAM survey from the Murchison Widefield Array (MWA) telescope, including the lowest surface-brig…
Candidate radio supernova remnants observed by the GLEAM survey over and
Natasha Hurley-Walker, Bryan M. Gaensler, Denis A. Leahy +18
We examined the latest data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey covering , $180^\circ < l < 240^\…
Extended X-ray emission in PKS 1718649
T. Beuchert, A. Rodríguez-Ardila, V. A. Moss +15
PKS 1718649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical host galaxy. The com…
Interplanetary Scintillation studies with the Murchison Wide-field Array II: Properties of sub-arcsecond compact sources at low radio frequencies
R. Chhetri, J. Morgan, R. D. Ekers +5
We report the first astrophysical application of the technique of wide-field Interplanetary Scintillation (IPS) with the Murchison Widefield Array (MWA). This powerful technique al…
Low frequency spectral energy distributions of radio pulsars detected with the Murchison Widefield Array
Tara Murphy, David L. Kaplan, Martin E. Bell +24
We present low-frequency spectral energy distributions of 60 known radio pulsars observed with the Murchison Widefield Array (MWA) telescope. We searched the GaLactic and Extragala…
Low Radio Frequency Observations and Spectral Modelling of the Remnant of Supernova 1987A
J. R. Callingham, B. M. Gaensler, G. Zanardo +17
We present Murchison Widefield Array observations of the supernova remnant (SNR) 1987A between 72 and 230 MHz, representing the lowest frequency observations of the source to date.…
Time-domain and spectral properties of pulsars at 154 MHz
M. E. Bell, Tara Murphy, S. Johnston +35
We present 154 MHz Murchison Widefield Array imaging observations and variability information for a sample of pulsars. Over the declination range we…
The X-ray Transient 2XMMi J003833.3+402133: A Candidate Magnetar at High Galactic Latitude
Joseph R. Callingham, Sean A. Farrell, Bryan M. Gaensler +2
We present detailed analysis of the transient X-ray source 2XMMi J003833.3+402133 detected by XMM-Newton in January 2008 during a survey of M 31. The X-ray spectrum is well fitted…
