Investigating the origin of radio emission in candidate super-Eddington accreting black holes
Marie-Lou Gendron-Marsolais, Paola Marziani, Marco Berton +8
Recent works show that the radio power of quasars accreting at very high rates can reach surprisingly high values. These studies suggest that this radio emission might originate fr…
The MPIfR-MeerKAT Galactic Plane survey I -- System setup and early results
P. V. Padmanabh, E. D. Barr, S. S. Sridhar +30
Galactic plane radio surveys play a key role in improving our understanding of a wide range of astrophysical phenomena. Performing such a survey using the latest interferometric te…
CHANG-ES XXIX: The Sub-kpc Nuclear Bubble of NGC 4438
Jiang-Tao Li, Q. Daniel Wang, Theresa Wiegert +8
AGN bubbles could play an important role in accelerating high-energy CRs and galactic feedback. Only in nearby galaxies could we have high enough angular resolution in multi-wavele…
CHANG-ES. XXIV. First Detection of A Radio Nuclear Ring and Potential LLAGN in NGC 5792
Yang Yang, Judith Irwin, Jiangtao Li +8
We report the discoveries of a nuclear ring of diameter 10$\arcsec$ (1.5 kpc) and a potential low luminosity active galactic nucleus (LLAGN) in the radio continuum emission m…
CHANG-ES XXIII: Influence of a galactic wind in NGC 5775
G. H. Heald, V. Heesen, S. S. Sridhar +22
We present new radio continuum images of the edge-on starburst galaxy NGC 5775, from LOFAR (140 MHz) and the Karl G. Jansky Very Large Array CHANG-ES survey (1500 MHz). We trace th…
Magnetism Science with the Square Kilometre Array
George Heald, Sui Ann Mao, Valentina Vacca +41
The Square Kilometre Array (SKA) will answer fundamental questions about the origin, evolution, properties, and influence of magnetic fields throughout the Universe. Magnetic field…
A Comprehensive Examination of the Optical Morphologies of 719 Isolated Galaxies in the AMIGA Sample
Ronald J. Buta, Lourdes Verdes-Montenegro, Ancor Damas-Segovia +7
Using images from Sloan Digital Sky Survey Data Release 8, we have re-examined the morphology of 719 galaxies from the Analysis of the interstellar Medium in Isolated GAlaxies (AMI…
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…
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…
The Radio Spectral Energy Distribution and Star Formation Rate Calibration in Galaxies
F. S. Tabatabaei, E. Schinnerer, M. Krause +17
We study the spectral energy distribution (SED) of the radio continuum emission from the KINGFISH sample of nearby galaxies to understand the energetics and origin of this emission…
CHANG-ES VIII: Uncovering Hidden AGN Activity in Radio Polarization
Judith A. Irwin, Philip Schmidt, A. Damas-Segovia +12
We report on C-band (5 - 7 GHz) observations of the galaxy, NGC~2992, from the CHANG-ES sample. This galaxy displays an embedded nuclear double-lobed radio morphology within its sp…
CHANG-ES VII: Magnetic outflows from the Virgo cluster galaxy NGC 4388
Ancor Damas-Segovia, Rainer Beck, Bernd Vollmer +8
We investigate the effects of ram pressure on the ordered magnetic field of a galaxy hosting a radio halo and strong nuclear outflows. New radio images in total and polarized inten…
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…
