Source counts and confusion at 72-231 MHz in the MWA GLEAM survey
T. M. O. Franzen, T. Vernstrom, C. A. Jackson +5
The GaLactic and Extragalactic All-sky MWA survey (GLEAM) is a radio continuum survey at 72-231 MHz of the whole sky south of declination +30 deg, carried out with the Murchison Wi…
CHANG-ES XII: A LOFAR and VLA view of the edge-on star-forming galaxy NGC 3556
A. Miskolczi, V. Heesen, C. Horellou +11
Low-frequency radio continuum studies of star-forming edge-on galaxies can help to further understand how cosmic-ray electrons (CRe) propagate through the interstellar medium into…
Exploring the properties of low-frequency radio emission and magnetic fields in a sample of compact galaxy groups using the LOFAR Two-Metre Sky Survey (LoTSS)
B. Nikiel-Wroczyński, A. Berger, N. Herrera Ruiz +14
We use the LOFAR Two-metre Sky Survey (LoTSS) Data Release I to identify the groups of galaxies (and individual galaxies) from the Hickson Compact Groups and Magnitude Limited Comp…
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…
Cold gas outflows from the Small Magellanic Cloud traced with ASKAP
N. M. McClure-Griffiths, H. Dénes, J. M. Dickey +19
Feedback from massive stars plays a critical role in the evolution of the Universe by driving powerful outflows from galaxies that enrich the intergalactic medium and regulate star…
WALLABY Early Science - I. The NGC 7162 Galaxy Group
Tristan N. Reynolds, Tobias Westmeier, Lister Staveley-Smith +21
We present Widefield ASKAP L-band Legacy All-sky Blind Survey (WALLABY) early science results from the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the NGC…
Circumgalactic gas at its extreme: tidal gas streams around the Whale galaxy NGC 4631 explored with HST/COS
P. Richter, B. Winkel, B. P. Wakker +8
We present a detailed analysis of the absorption properties of one of the tidal gas streams around the Whale galaxy NGC4631 in the direction of the quasar 2MASSJ12421031+3214268. O…
cuFFS: A GPU-accelerated code for Fast Faraday Rotation Measure Synthesis
S. S. Sridhar, G. Heald, J. M. van der Hulst
Rotation measure (RM) synthesis is a widely used polarization processing algorithm for reconstructing polarized structures along the line of sight. Performing RM synthesis on large…
LOFAR MSSS: Flattening low-frequency radio continuum spectra of nearby galaxies
K. T. Chyży, W. Jurusik, J. Piotrowska +35
The shape of low-frequency radio continuum spectra of normal galaxies is not well understood, the key question being the role of physical processes such as thermal absorption in sh…
Shock location and CME 3D reconstruction of a solar type II radio burst with LOFAR
P. Zucca, D. E. Morosan, A. P. Rouillard +62
Type II radio bursts are evidence of shocks in the solar atmosphere and inner heliosphere that emit radio waves ranging from sub-meter to kilometer lengths. These shocks may be ass…
Investigation of the cosmic ray population and magnetic field strength in the halo of NGC 891
D. D. Mulcahy, A. Horneffer, R. Beck +24
Low-frequency radio continuum observations of edge-on galaxies are ideal to study cosmic-ray electrons (CREs) in halos via radio synchrotron emission and to measure magnetic field…
Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR
V. Heesen, D. A. Rafferty, A. Horneffer +16
Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role, they can be best traced with low-frequency radio continuum observations,…
Radio haloes in nearby galaxies modelled with 1D cosmic-ray transport using SPINNAKER
V. Heesen, M. Krause, R. Beck +10
We present radio continuum maps of 12 nearby (), edge-on (), late-type spiral galaxies mostly at and 5 GHz, observed with the Australia Te…
