Bulgeless Giant Galaxies Challenge our Picture of Galaxy Formation by Hierarchical Clustering

We dissect giant Sc-Scd galaxies with Hubble Space Telescope photometry and Hobby-Eberly Telescope spectroscopy. We use HET's High Resolution Spectrograph (resolution = 15,000) to measure stellar velocity dispersions in the nuclear star clusters and pseudobulges of the pure-disk galaxies M33, M101, NGC 3338, NGC 3810, NGC 6503, and NGC 6946. We conclude: (1) Upper limits on the masses of any supermassive black holes are MBH <= (2.6+-0.5) * 10**6 M_Sun in M101 and MBH <= (2.0+-0.6) * 10**6 M_Sun in NGC 6503. (2) HST photometry shows that the above galaxies contain tiny pseudobulges that make up <~ 3 % of the stellar mass but no classical bulges. We inventory a sphere of radius 8 Mpc centered on our Galaxy to see whether giant, pure-disk galaxies are common or rare. In this volume, 11 of 19 galaxies with rotation velocity > 150 km/s show no evidence for a classical bulge. Four may contain small classical bulges that contribute 5-12% of the galaxy light. Only 4 of the 19 giant galaxies are ellipticals or have classical bulges that contribute 1/3 of the galaxy light. So pure-disk galaxies are far from rare. It is hard to understand how they could form as the quiescent tail of a distribution of merger histories. Recognition of pseudobulges makes the biggest problem with cold dark matter galaxy formation more acute: How can hierarchical clustering make so many giant, pure-disk galaxies with no evidence for merger-built bulges? This problem depends strongly on environment: the Virgo cluster is not a puzzle, because >2/3 of its stellar mass is in merger remnants.Comment: 28 pages, 16 Postscript figures, 2 tables; requires emulateapj.sty and apjfonts.sty; accepted for publication in ApJ; for a version with full resolution figures, see http://chandra.as.utexas.edu/~kormendy/kdbc.pd

A FERTILIZER-RATE EXPERIMENT INVOLVING YOUNG CITRUS TREES: DOES MORE FERTILIZER MEAN HIGHER PRODUCING TREES?

Citrus growers are interested in making money. So, the most common practice among growers is to push young trees into early production by the application of high amounts (rates) of fertilizer. This practice can lead to disaster in terms of tree formation (canopy shape) and production stress. In contrast, when the applied fertilizer approaches both the optimum rate and the optimum N -P -K -Ca ratio for citrus, then the trees are more uniform in size and with compact canopies and the incidence of decline is less. Cordieropolis station in Sao Paula, Brazil, is the site of a large 3-component by 3 rates fertilizer experiment on young citrus (orange) trees. We shall present the statistical aspects (design, model, and the method of data analysis) of the experiment along with the surprising results obtained thus far
