The new species is a member of an apparently monophyletic group within the genus that includes R. flexile, R. walga, R. himanturi, R. burgeri, R. euzeti, R. hawaiiensis, R. urobatidium, R. paratrygoni, R. ditesticulum, R. tetralobatum, R. margaritense, R. biorchidum, and R. spinicephalum. All of these species have bothridia with medial longitudinal septa, a constriction at mid-bothridium, and, ...

The COBE FIRAS data contain foreground emission from interplanetary, Galactic interstellar dust and extragalactic background emission. We use three different methods to separate the various emission components, and derive the spectrum of the extragalactic Far InfraRed Background (FIRB). Each method relies on a different set of assumptions, which affect the FIRB spectrum in different ways. Despi...

Submillimetre (submm)-wave observations have revealed a cosmologically significant population of high-redshift dust-enshrouded galaxies. The form of evolution inferred for this population can be reconciled easily with COBE FIRAS and DIRBE measurements of the cosmic background radiation (CBR) intensity at wavelengths longer than about 100μm. At shorter wavelengths, however, the 60-μm CBR intensi...

The FIRAS instrument on the COBE satellite has conducted an unbiased survey of the far-infrared emission from our Galaxy. The rst results of this survey were reported by Wright et al. (1991). We report the results of new analyses of this spectral survey, which includes emission lines from 158 m C + , 122 m and 205 m N + , 370 m and 609 m C 0 , and CO J=2-1 through 5-4. We report the morphologic...

Context. CO observations have been so far the best way to trace molecular gas in external galaxies, but in low metallicity environments the gas mass deduced could be largely underestimated due to enhanced photodissociation of the CO molecule. Large envelopes of H2 could therefore be missed by CO observations. Aims. At present, the kinematic information of CO data cubes are used to estimate viri...

(NASA/GSFC) was responsible for the design, development, and operation of the Cosmic Background Explorer (COBE). GSFC was also responsible for the development of the analysis software and for the production of the mission data sets. The COBE program was supported by the Astrophysics Division of NASA's Office of Space Science and Applications. ABSTRACT The photometric errors of the external cali...

NASA’s Cosmic Background Explorer (COBE) Satellite has recently made the most accurate measurement of the temperature of the Universe determining it to be 2.726± 0.01K. In trying to understand why the temperature has this value, one is led to discover the most fundamental features of the Universe—an early, radiation-dominated epoch, enormous entropy per nucleon, synthesis of the light elements ...
