Possible fast variability of the nucleus of Cen A at 13.5 mm

Abstract

INFORMATION about short time scale events in extragalactic objects can have very important implications for the theoretical interpretation of the physical mechanisms involved. Such data are only obtained by using time-consuming observing schedules and methods, and are not usually carried out at radio observatories. This kind of information is thus generally lacking. We report here a study of the nucleus of Cen A (NGC 5128) at a wavelength of 13.5mm. Possible fast variability was observed.
