Intensity Mapping of H α , H β , O II [ ] , and O III [ ] Lines at z < 5

Intensity mapping is becoming a useful tool to study the large-scale structure of the universe through spatial variations in the integrated emission from galaxies and the intergalactic medium. We study intensity mapping of the a H 6563 Å, [O III] 5007Å, [O II] 3727Å, and b H 4861 Å lines at   z 0.8 5.2. The mean intensities of these four emission lines are estimated using the observed luminos...

An XMM - Newton observation of the multiple system HD 167971 ( O 5 - 8 V + O 5 - 8 V + ( O 8 I ) ) and the young open cluster NGC 6604 ⋆

We discuss the results of two XMM-Newton observations of the open cluster NGC 6604 obtained in April and September 2002. We concentrate mainly on the multiple system HD 167971 (O5-8V + O5-8V + (O8I)). The soft part of the EPIC spectrum of this system is thermal with typical temperatures of about 2 × 10 6 to 9 × 10 6 K. The nature (thermal vs non-thermal) of the hard part of the spectrum is not ...

Luminescence of CS 3 V 2 O 4 F 5

The luminescence of complex ions like vanadate, niobate and tungstate is well known and has been studied intensively [1]. We have shown that edgeor face-sharing octahedra of this type are luminescent species with high quenching temperatures [2,3]. Examples are Mg4Nb20g and BasSrNb209 with Nb20g8_ anions and Ba3W20g with W2O96anions. These anions consist of face-sharing niobate and tungstate oct...

A. Z. v. B. Z. (2000)

In A.Z. v. B.Z. (2000), the Supreme Judicial Court of Massachusetts in Boston, Massachusetts, affirmed a lower court?s decision, ruling that contracts that require a party to become a parent against his or her will are unenforceable and contrary to public policy. The case centered around A.Z. and B.Z., a divorced couple who had previously used in vitro [4] fertilization [5] (IVF) to start a fam...
