We present observations of the spiral galaxy M33 with Spitzer at 24, 70, and 160 ЮМm. ... We compare the morphology of M33 at far-infrared wavelengths with other standard SF indicators such as HЮБ and radio continuum using a Fourier filtering technique to separate the diffuse emission components from compact sources. We find that the infrared emission at 24 and 70 ЮМm follows closely the structure of the ionized gas, indicating that it is heated largely by hot, ionizing stars. ... citations = 45 . ...

Abstract: In recent years our observational knowledge of several important components of the central region of Centaurus A has increased dramatically: high resolution X-ray observations have revealed unprecedented detail in the jet and surrounding atmosphere; a kpc sized bipolar shell has been detected in the mid-IR; -rays have been detected in the GeV domain by Fermi and in the TeV domain by HESS. ...

... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...

... We detect three main diffuse components: the Virgo ICM at ~2.4 keV, the extended halo of M86 at ~1.2 keV, and the cooler central and stripped gas of M86 at ~0.8 keV. The most striking feature is a long tail of emission, which consists of a plume ~ 4' north of M86 and two main extensions emanating from the plume. ... Ram pressure stripping from an aspherical potential can also explain the split "double tails" seen in M86 and in other Virgo cluster galaxies in the field. ...

Dynamic magnetic fields continuously emerging from the solar interior on a wide range of scales, and their interaction with convectively-driven plasma flows, play a major role in shaping the whole solar atmosphere. Even though the fundamental spatial scales of turbulence and magnetic fields are still unreachable with present-day telescopes, polarimetric observations at the highest possible resolution will allow important insights into these issues. ...

Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
