We discuss images of M87 from 3.6 to 160 μm obtained with Spitzer. As found previously, there is an excess in the far-infrared over a simple power-law interpolation from the radio to the resolved nonthermal features in the mid-infrared and optical. We show that this excess is most likely due to warm dust in the galaxy itself and that the properties of this emission component are similar to the far-infrared emission of normal giant elliptical galaxies. The new observations allow us to determine… 

THE INFRARED JET IN 3C 31

We report the detection of infrared emission from the jet of the nearby Fanaroff–Riley type I radio galaxy 3C 31. The jet was detected with the IRAC instrument on Spitzer at 4.5 μm, 5.8 μm, and 8.0

The far-infrared view of M87 as seen by the Herschel Space Observatory

Abstract The origin of the far-infrared emission from the nearby radio galaxy M87 remains a matter of debate. Some studies find evidence of a far-infrared excess due to thermal dust emission, whereas

THE ROLE OF THE SYNCHROTRON COMPONENT IN THE MID-INFRARED SPECTRUM OF M 87

We study in detail the mid-infrared (MIR) Spitzer-IRS spectrum of M 87 in the range 5–20 μm. Thanks to the high sensitivity of our Spitzer-IRS spectra we can disentangle the stellar and nuclear

An Infrared Study of the Large-Scale Jet in Quasar PKS 1136–135

We present Spitzer IRAC imaging of the large-scale jet in the quasar PKS 1136-135 at wavelengths of 3.6 and 5.8 μm, combined with previous VLA, HST, and Chandra observations. We clearly detect

Combined Spitzer, Chandra, XMM-Newton, and VLA observations of the giant radio galaxy NGC 1316 (Fornax A) show a radio jet and X-ray cavities from active galactic nucleus (AGN) outbursts most likely

THE SPITZER VIEW OF FR I RADIO GALAXIES: ON THE ORIGIN OF THE NUCLEAR MID-INFRARED CONTINUUM

We present Spitzer mid-infrared (MIR) spectra of 25 FR I radio galaxies and investigate the nature of their MIR continuum emission. MIR spectra of star-forming galaxies and quiescent elliptical

Infrared–red cores in nearby elliptical galaxies

We present the Spitzer Space Telescope Infrared Array Camera observations for a sample of local elliptical galaxies to study later stages of active galactic nucleus (AGN) activity. A sample of 36

The subarcsecond mid-infrared view of local active galactic nuclei – I. The N- and Q-band imaging atlas

We present the first subarcsecond-resolution mid-infrared (MIR) atlas of local active galactic nuclei (AGN). Our atlas contains 253 AGN with a median redshift of z = 0.016, and includes all publicly

The Herschel Virgo Cluster Survey - VI. The far-infrared view of M 87

The origin of the far-infrared emission from the nearby radio galaxy M 87 remains a matter of debate. Some studies find evidence of a far-infrared excess due to thermal dust emission, whereas others

Chandra and VLA Observations of Supermassive Black Hole Outbursts in M87

Abstract We discuss the effects of supermassive black hole (SMBH) outbursts on the hot atmospheres surrounding the central massive galaxies in groups and clusters, as observed with X-ray and radio
