Figure 1: Histogram showing the detection rates of 15 GHz radio nuclei for ULIRGs with nuclear emission lines characteristic of (from left to right) Seyfert 1s, Seyfert 2s, LINERs, transitional Seyfert/LINER plus H II regions, and pure H II regions. The total and filled histograms show all radio-observed and all radio-detected ULIRGs, respectively. Activity type classifications are from Veilleux et al. (1999a). The radio detection rate is significantly higher among Seyferts and LINERs than among pure H II nuclei. |

Figure 2:
Histograms of
(top) absolute magnitude of the inner 4 kpc of the ULIRG component in the
band (i.e. AGN + galaxy), when available;
(bottom) absolute magnitude of the (total) ULIRG in the
band.
Data are from VSK and KVS.
The total and filled histograms represent all ULIRGs (or all ULIRG components)
observed and detected in the radio by us, respectively.
Note that the horizontal scales are different between top and bottom panels.
The radio detection rate increases with increasing nuclear (AGN plus central 4 kpc
of nucleus) -band luminosity but is independent of the
luminosity of the
total ULIRG.

Figure 3: 15 GHz (2 cm) VLA map of IRAS F23389+0300 (4C 03.60). The crosses mark the positions of the two near-IR nuclei and their average position, and the rectangle marks the position of the northern optical nucleus (KVS). The southern optical nucleus lies off the bottom of the figure. |
