We report 0.9-1.4um spectroscopic observations of NGC1068 collected during the commissioning phase of the near infrared camera spectrometer (NICS) of the Telescopio Nazionale Galileo (TNG). These yielded the first extragalactic measurement of PII (1.188um) line emission. In the central 0.75"x2" the FeII/PII line-intensity ratio is close to unity, similar to that measured in the Orion bar and a factor of . Mantained by: Leonardo Testi .

The most massive black holes in the nearby Universe seem to largely be hosted by massive central cluster galaxies. The ultra-massive black hole in NGC 1277, reported by van den Bosch et al. based on a stellar kinematic measurement, is an extreme outlier in this respect. NGC 1277 is not a central cluster galaxy, but a lenticular galaxy in the Perseus Cluster, at a distance of about 3.8 from the central cluster galaxy. ...
