Multi-frequency study of supernova remnants and H II regions in NGC300

open access: yes, 2004
We present a multi-frequency study of supernova remnants (SNRs) and HII regions in the nearby Sculptor Group Sd galaxy NGC300, based on new ATCA observations at the wavelengths of 13 and 20 cm, XMM-Newton observations, newly-processed ROSAT (PSPC/HRI ...

e-EVN monitoring of M87 [PDF]

open access: yes, 2010
M87 is a privileged laboratory for a detailed study of the properties of jets, owing to its proximity (D=16.7 Mpc, 1 mas = 0.080 pc), its massive black hole (~6.0 x 10^9M) and its conspicuous emission at radio wavelengths and above.

STAGES:the Space Telescope A901/2 Galaxy Evolution Survey [PDF]

open access: yes, 2008
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide range of environments and luminosity.

CGCG 292-057: A Near-Distance Merger Galaxy with Double–Double Radio Lobes and X-shape Structure

open access: yesJournal of Astrophysics and Astronomy, 2011
J1159+5820 is an extended radio galaxy with a quite unusual morphology, featuring two pairs of radio lobes. Such sources, called double–double radio galaxies, constitute a very rare class of extragalactic radio sources. Furthermore, the extended radio structure of this source shows an X-shape form. According to a much likely scenario, such a morphology

A Chandra study of the multi-component X-ray emission of the X-shaped radio galaxy 3C 403

open access: yes, 2005
We present results from a 49.4 ks Chandra ACIS-S observation of the nearby (z = 0.059) X-shaped FR type II (FR II) radio galaxy 3C 403. This is the first Chandra observation of an X-shaped radio galaxy, and one of the goals of this pioneering study is to

X-shaped radio galaxies: probing jet evolution, ambient medium dynamics, and their intricate interconnection

open access: yesFrontiers in Astronomy and Space Sciences
This review explores the field of X-shaped radio galaxies (XRGs), a distinctive subset of winged radio sources that are identified by two pairs of jetted lobes which aligned by a significant angle, resulting in an inversion-symmetric structure. These lobes, encompassing active (primary) and passive (secondary) phases, exhibit a diverse range of ...

AGN outflows and the cluster cooling flow conundrum

open access: yes, 2011
Temperature distributions within cores of galaxy clusters indicate gas in the core should cool down rapidly and contract. The cooling flow problem involves the hypothesis that the rapidly cooling gas should eventually condensate into unobserved molecular

Evidence for In - Situ Acceleration of Relativistic Particles in the Wings of X-shaped Radio Galaxies

open access: yesThe Astrophysical Journal
Abstract We report evidence for in - situ acceleration/reacceleration of relativistic particles in 11 radio wings out of a total of 68 wings sufficiently well-resolved for spectral mapping, which belong to our sample of 40 X-shaped ...

The Hot Atmospheres of X-shaped Radio Galaxies [PDF]

open access: yes, 2011
We present an observational and numerical study of X-shaped radio galaxies, a subset of the double-lobed radio galaxies with a second set of lobes or "wings".
