Modelling jet-driven molecular outflows
We have investigated the basic physical properties of the outflow that is created by a supersonic jet in a dense molecular cloud. We show that the dynamics of the interaction is strongly controlled by the rapi...

A 45 AU Radius Source around L1551-IRS 5: A Possible Accretion Disk
Our interferometric and single-dish observations of the continuum emission from L1551-IRS 5 show that, at millimeter wavelengths, there are two distinct components to the source, an envelope with a radius ≥ 20...

A Search for Dense Gas Around Young Stars
We searched for CS(7–6) emission in a range of young stars, to test for the presence of dense gas. CS emission was detected only towards high-luminosity objects. We suggest that this is because the low-luminos...

A Submillimeter Line Survey of Sgr B2
We have surveyed molecular line emission from Sgr B2 between 330 and 355 GHz. By observing two separate positions within the molecular cloud we hoped to be able to study the degree of chemical differentiation ...

A New Technique for Surface Measurements of Radio Telescopes
In order to optimize the surface figure of the parabolic primary mirror of the Caltech Submillimeter Observatory, holographic measurements of the dish surface are being carried out. A new holographic technique...

CO (1–0) Maps of NGC7027
NGC7027 is a very young planetary nebula in which the ionization of the red giant wind is only partially complete. Previous measurements of the CO (1–0) emission at 115 GHz from NGC7027 (Mufson, Lyon, Marioni,...

CO (2−1) Observations of Maffei 2
Maffei 2 is a highly obscured galaxy, probably of type Sbc, at a distance of 5 Mpc (Allen and Raimond 1972; Spinrad et al. 1973). Since it lies close to the Galactic plane, there is considerable confusion in infr...

Very long baseline interferometry at a wavelength of 3.4 mm
In recent years the angular distribution of intensity of the compact cores of quasars and radio galaxies has been mapped in detail by very long baseline interferometry (VLBI) arrays1,2. These observations have sh...

Reply to Gordon and Judd
ALTHOUGH expressions similar to that of Flory1 have been derived by several authors for the size distribution in branched polymers it has been assumed, implicitly or explicitly, in such derivations that the conve...

Determination of Oxygen in Iron and Steel
WE have recently applied the method of stable isotope dilution1 to the determination of oxygen in samples of iron and steel which contained low concentrations of this element. As our results are consistently high...

Bacterial Cellulose for Osmometer Membranes
IN the investigation of the mechanism of polymerization reactions, it is essential to be able to count the number of polymer molecules produced. This implies that the number average molecular weight has to be ...
