Theoretical Predictions for Surface Brightness Fluctuations and Implications for Stellar Populations of Elliptical Galaxies
We compute theoretical predictions for surface brightness fluctuations (SBFs) of single-burst stellar populations (SSPs) using models optimized for this purpose. We present results over a wide range of ages (from 1 to 17 Gyr) and metallicities (from 1/200 to 2.5 times solar) and for a comprehensive set of ground-based and space-based optical and infrared bandpasses. Our models agree well with e...
متن کاملFollowing comets
an inferior hand of genes. Fetuses are today commonly screened for genetic disorders and this service will no doubt expand. An American company has devised a one-inch chip carrying 400,000 DNA fragments, which will allow the entire human genome to be screened for an average of four alleles per gene. The difference between eliminating the undesirable and promoting the advantageous is becoming to...
متن کاملSMALL COMETS' IMPLICATIONS FOR INTERPLANETARY LYMAN a
If small comets are as numerous in the inner solar system as Prank et al. [1986a] have recently proposed, large and easily detectable amounts of hydrogen would be generated in interplanetary space. Inhibition of water vapor production by a factor of 3 x 10 -9 by very thick dust mantles would be necessary to prevent excitation of a detectable interplanetary Lyman a glow. Other optical problems a...
متن کاملMedical Comets: Scholarly Contributions
collection of pages from lecture notes, the lab manual, and figures from Haines and Nolte. In other words, for medical students studying neuroanatomy there was no single yet comprehensive source that would address the gritty neuroanatomical details and yet present integrative cases that would illustrate the diseases such as Parkinson's in the context of a clinical setting. So when I had the cha...
متن کاملSubmillimeter Continuum Emission from Comets
We report submillimeter continuum observations of five comets obtained at the James Clerk Maxwell Telescope on Mauna Kea. Two of the five comets (P/Brorsen-Metcalf and Okazaki-Levy-Rudenko) were detected at 800-~m wavelength, while physically significant upper limits were placed on the other three (Austin 1989Cl, P/Faye, and Levy 1990c). We compare the JCMT • data with millimeter continuum meas...
