Re:MAFFEI 2
MAFFEI 2: This spiral is also heavily obscured. The internal nuclear extinction
has also been found to be large, with A_V_ >~ 10 mag (Hurt & Turner 1991; Hurt
et al. 1993). The nuclear region is the site of a vigorous burst of star
formation, indicated by radio continuum emission (Turner & Ho 1994), strong
infrared emission (Rickard & Harvey 1983; Ho et al. 1989), as well as NIR (Ho et
al. 1990) and optical emission lines (Fig. 2). The nucleus of the galaxy is
obvious in our NIR images. Five radio sources are found within a radius of ~100
pc (see Table 2). Spectral observations were only obtained in the red; hence, no
spectral classification was possible. Spectra were taken at the position of the
brightest optical source and two radio sources (see Table 5). One of the radio
sources (source 2) seems to be coincident with the IR peak while the other radio
source (source 3) is coincident with an optical knot. The optical images clearly
show the effects of dust extinction. These are much reduced in the J-band image,
where we see a bright nuclear source that is not seen in the optical images.
