... Fractional flux density variations of between 5 and 100 per cent (typically 15-25 per cent) have been detected on a range of time-scales from 1 to 12 years. ... The 151-MHz flux densities have been indirectly scaled to the 6C flux scale. ... Amongst the 72 sources for which the chance of being a true variable is greater than 0.8, typical maximum flux density variations of 15-25 per cent are seen; eight objects show variations greater than 50 per cent, with one source varying by more than 100 per...

Aims:We investigate the energy sources of the infrared (IR) emission and their relation to the radio continuum emission at various spatial scales within the Scd galaxy M 33. ... We use the wavelet transform of these maps to a) separate the diffuse emission components from compact sources, b) compare the emission at different wavelengths, and c) study the radio-IR correlation at various spatial scales. ... We also find a strong correlation between the 3.6 cm and HЮБ emission at all scales. ...
