The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
Learning from the present for the future: the Juelich LOFAR Long-term Archive
C. Manzano, A. Miskolczi, H. Stiele. +3
The Forschungszentrum Juelich has been hosting the German part of the LOFAR archive since 2013. It is Germany's most extensive radio astronomy archive, currently storing nearly 22…
Warped diffusive radio halo around the quiescent spiral edge-on galaxy NGC 4565
V. Heesen, L. Whitler, P. Schmidt +12
Cosmic rays play a pivotal role in launching galactic winds, particularly in quiescently star-forming galaxies where the hot gas alone is not sufficient to drive a wind. Except for…
CHANG-ES XX. High Resolution Radio Continuum Images of Edge-on Galaxies and their AGNs -- Data Release 3
Judith Irwin, Theresa Wiegert, Alison Merritt +17
The CHANG-ES galaxy sample consists of 35 nearby edge-on galaxies that have been observed using the VLA at 1.6 GHz and 6.0 GHz. Here we present the 3rd data release of our sample,…
CHANG-ES: XVIII---The CHANG-ES Survey and Selected Results
Judith Irwin, Ancor Damas-Segovia, Marita Krause +8
The CHANG-ES (Continuum Halos in Nearby Galaxies) survey of 35 nearby edge-on galaxies is revealing new and sometimes unexpected and startling results in their radio continuum emis…
First detection of frequency-dependent, time-variable dispersion measures
J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +11
Context. High-precision pulsar-timing experiments are affected by temporal variations of the Dispersion Measure (DM), which are related to spatial variations in the interstellar el…
CHANG-ES XIII: Transport processes and the magnetic fields of NGC 4666 - indication of a reversing disk magnetic field
Y. Stein, R. -J. Dettmar, J. Irwin +10
We analyze the magnetic field geometry and the transport processes of the cosmic rays of the edge-on spiral starburst galaxy NGC 4666 from CHANG-ES radio continuum data in two freq…
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…
Systematic search for tidal features around nearby galaxies: I. Enhanced SDSS imaging of the Local Volume
Gustavo Morales, David Martínez-Delgado, Eva K. Grebel +3
In hierarchical models of galaxy formation, stellar tidal streams are expected around most, if not all, galaxies. Although these features may provide useful diagnostics of the C…
CHANG-ES XI: Circular Polarization in the Cores of Nearby Galaxies
Judith A Irwin, Richard N. Henriksen, Marek Wezgowiec +18
We detect 5 galaxies in the CHANG-ES (Continuum Halos in Nearby Galaxies -- an EVLA Survey) sample that show circular polarization (CP) at L-band in our high resolution data sets.…
CHANG-ES IX: Radio scale heights and scale lengths of a consistent sample of 13 spiral galaxies seen edge-on and their correlations
Marita Krause, Judith Irwin, Theresa Wiegert +14
The vertical halo scale height is a crucial parameter to understand the transport of cosmic-ray electrons (CRE) and their energy loss mechanisms in spiral galaxies. Until now, the…
CHANG-ES IV: Radio continuum emission of 35 edge-on galaxies observed with the Karl G. Jansky Very Large Array in D-configuration, Data Release 1
Theresa Wiegert, Judith Irwin, Arpad Miskolczi +21
We present the first part of the observations made for the Continuum Halos in Nearby Galaxies, an EVLA Survey (CHANG-ES) project. The aim of the CHANG-ES project is to study and ch…
