CHANG-ES XXXVII. Effects of spectral aging on radio scale heights
D. C. Smolinski, V. Heesen, M. Brüggen +7
Context. Cosmic rays and magnetic fields play an important role for the formation and evolution of galaxies. Radio continuum observations allows us to study them in the haloes of e…
Multiwavelength investigations of PKS 2300-18: S-shaped radio quasar with precessing jets and double-peaked broad emission-line spectrum
Arpita Misra, Marek Jamrozy, Marek Weżgowiec +1
S-shaped radio galaxy jets are prime sources for investigating the dynamic interplay between the central active galactic nucleus, the jets, and the ambient intergalactic medium. Th…
The low-frequency flattening of the radio spectrum of giant HII regions in M 101
L. Gajović, V. Heesen, M. Brüggen +10
In galaxies, the flattening of the spectrum at low radio frequencies below 300 MHz has been the subject of some debate. A turnover at low frequencies could be caused by multiple ph…
The twisted jets and magnetic fields of the extended radio galaxy 4C 70.19
M. Weżgowiec, M. Jamrozy, K. T. Chyży +4
The appearance of the jets and lobes of some radio galaxies makes it difficult to assign them to a known class of objects. This is often due to the activity of the central engine a…
Hot magnetic halo of NGC628 (M74)
M. Wezgowiec, R. Beck, M. Hanasz +4
In several spiral galaxies that are observed face-on, large-scale ordered magnetic fields (the so-called magnetic arms) were found. One of the explanations was the action of the ma…
Magnetic fields and hot gas in M101
M. Wezgowiec, R. Beck, M. Hanasz +4
Studies of nearby spiral galaxies in radio and X-ray wavelengths reveal the structure and energy balance of the magnetic fields and the hot interstellar medium (ISM). In some spira…
Hot gas heating via magnetic arms in spiral galaxies. The case of M 83
M. Wezgowiec, M. Ehle, M. Soida +3
Reconnection heating has been considered as a potential source of the heating of the interstellar medium. In some galaxies, significant polarised radio emission has been found betw…
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 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 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.…
Optical and radio properties of extragalactic radio sources with recurrent jet activity
A. Kuźmicz, M. Jamrozy, D. Kozieł-Wierzbowska +1
We present a sample of 74 radio sources with recurrent jet activity. The sample consists of 67 galaxies, 2 quasars and 5 unidentified sources, selected from the published data or a…
Dynamical analysis of the complex radio structure in 3C 293: Clues on a rapid jet realignment in X-shaped radio galaxies
J. Machalski, M. Jamrozy, L. Stawarz +1
Radio galaxies classified as X-shaped/winged, are characterised by two pairs of extended and misaligned lobes, which suggest a rapid realignment of the jet axis, for which a potent…
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…
1.4-GHz observations of extended giant radio galaxies
M. Wezgowiec, M. Jamrozy, K. -H. Mack
This paper presents 1.4-GHz radio continuum observations of 15 very extended radio galaxies. These sources are so large that most interferometers lose partly their structure and to…
Hot gas and magnetic arms of NGC 6946: indications for reconnection heating?
M. Wezgowiec, M. Ehle, R. Beck
The grand-design face-on spiral galaxy NGC6946 is remarkable because of its high star formation activity, the massive northern spiral arm, and the magnetic arms, which are observed…
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…
M82 - A radio continuum and polarisation study I. Data reduction and cosmic ray propagation
B. Adebahr, M. Krause, U. Klein +3
The potential role of magnetic fields and cosmic ray propagation for feedback processes in the early Universe can be probed by studies of local starburst counterparts with an equiv…
