Abstract (from CDS):

We present a large sample of H - and K -band spectra of 32 optically line-luminous central cluster galaxies. We find significant rovibrational H2emission in 23 of these galaxies as well as H recombination and/or [Feii] emission in another five. This represents a fourfold increase in the number of molecular line detections known. A number of the detections are of extended emission (5-20 kpc). In several objects we find significant [Sivi] emission that appears to correlate with the strength of high ionization lines in the optical (e.g. [Oiii]). This comprehensive sample builds on previous work and confirms that warm (1000-2500 K) molecular hydrogen is present wherever there is ionized material in the cores of cooling flows and in most cases it also coincides with CO molecular line emission.
