ROSAT PSPC and Hri Observations of the Composite Starburst/Seyfert 2 Galaxy NGC 1672
The nearby barred spiral galaxy NGC 1672 is thought to have a weak Seyfert
nucleus in addition to its strong starburst activity. Observations with the
PSPC and HRI instruments on board the ROSAT X-ray satellite show that three
X-ray sources with luminosities (1--2)\times 10^{40} erg/s are clearly
identified with NGC 1672. The strongest X-ray source lies at the nucleus, and
the other two lie near the ends of the prominent bar, locations that are also
bright in H-alpha and near-infrared images. The nuclear source is resolved by
the HRI on about the scale of the recently identified nuclear ring, and one of
the sources at the ends of the bar is also probably resolved. The X-ray
spectrum of the nuclear source is quite soft, having a Raymond--Smith plasma
temperature of about 0.7 keV and little evidence for intrinsic absorption. The
ROSAT band X-ray flux of the nuclear source appears to be dominated not by
X-ray binary emission but rather by diffuse gas emission. While the properties
of the nuclear source are generally supportive of a superbubble interpretation,
its large density and emission measure stretch the limits that can be
comfortably accommodated by such models. We do not detect direct emission from
the putative Seyfert nucleus, although an alternative model for the nuclear
source is thermal emission from gas that is photoionized by a hidden Seyfert
nucleus. The spectra of the other two X-ray sources are harder than that of the
nuclear source, and superbubble models for them have the same strengths and
weaknesses.Comment: 11 pages, uuencoded compressed postscript, MNRAS in pres
The Right of Publicity: Commercial Exploitation of the Associative Value of Personality
For more than thirty years, dispute and confusion have marked the emergence and development of the so-called right of publicity, \u27 a right that is concerned with the use of attributes of a generally identifiable person to enhance the commercial value of an enterprise. A dense, complex array of cases, accompanied by and analyzed in an even denser array of commentary, has been the vehicle for adumbrating the emergent right. Battle lines are drawn over whether the creature emerging from the fermenting ooze of modern mass communications is a species of property or a purely personal privacy interest. Everywhere one finds the bodies of tortured analogies:\u27 Is the chimera more like copyright? Should it be in the trademark or service mark bestiary? Do we perhaps have simply another version of the old torts of misappropriation and unfair competition? There is general agreement only about the genesis of this haystack in a hurricane. The right of publicity as currently understood was born out of the determination of the Second Circuit in Haelan Laboratories, Inc. v. Topps Chewing Gum, Inc. that a celebrity has a right to damages and other relief for the unauthorized commercial appropriation of the celebrity\u27s persona and that such a right is independent of a common law or statutory right of privacy
