Predicting The Progress Of Diffusively Limited Chemical Reactions In The Presence Of Chaotic Advection, Paulo E. Arratia, Jerry P. Gollub
Predicting The Progress Of Diffusively Limited Chemical Reactions In The Presence Of Chaotic Advection, Paulo E. Arratia, Jerry P. Gollub
Faculty Publications
In this significant paper, submitted in 2006 and published in 2006, we showed that the progress of a chemical reaction can be predicted from measurements of the stretching of fluid elements, which is essential to mixing. This work was highlighted in the News and Discovery section of Physics Today. Physical Review Letters provides 'coverage of major advances in all aspects of physics and of developments with significant consequences across subdisciplines.' Letters are required to be of broad interest. -- author-supplied description

A Survey Of 56 Midlatitude Egret Error Boxes For Radio Pulsars, Fronefield Crawford
A Survey Of 56 Midlatitude Egret Error Boxes For Radio Pulsars, Fronefield Crawford
Faculty Publications
We have conducted a radio pulsar survey of 56 unidentified γ-ray sources from the third EGRET catalog that are at intermediate Galactic latitudes (5° < |b| < 73°). For each source, four interleaved 35 minute pointings were made with the 13 beam, 1400 MHz multibeam receiver on the Parkes 64 m radio telescope. This covered the 95% error box of each source at a limiting sensitivity of ~0.2 mJy to pulsed radio emission for periods P 10 ms and dispersion measures 50 pc cm-3. Roughly half of the unidentified γ-ray sources at |b| > 5° with no proposed active galactic nucleus counterpart were covered in this survey. We detected nine isolated pulsars and four recycled binary pulsars, with three from each class being new discoveries. Timing observations suggest that only one of the pulsars has a spin-down luminosity that is even marginally consistent with the inferred luminosity of …
Discovery Of 14 Radio Pulsars In A Survey Of The Magellanic Clouds, Richard N. Manchester, G. Fan, A. G. Lyne, V. M. Kaspi, Fronefield Crawford
Discovery Of 14 Radio Pulsars In A Survey Of The Magellanic Clouds, Richard N. Manchester, G. Fan, A. G. Lyne, V. M. Kaspi, Fronefield Crawford
Faculty Publications
A systematic survey of the Large and Small Magellanic Clouds for radio pulsars using the Parkes radio telescope and the 20 cm multibeam receiver has resulted in the discovery of 14 pulsars and the redetection of five of the eight previously known spin-powered pulsars believed to lie in the Magellanic Clouds. Of the 14 new discoveries, 12 are believed to lie within Clouds, three in the Small Cloud and nine in the Large Cloud, bringing the total number of known spin-powered pulsars in the Clouds to 20. Averaged over all positions within the survey area, the survey had a limiting …

Simulated Molecular Outflows In Galaxy Mergers With Embedded Agn, Desika Narayanan
Simulated Molecular Outflows In Galaxy Mergers With Embedded Agn, Desika Narayanan
Faculty Publications
We study the effects of feedback from active galactic nuclei (AGNs) on emission from molecular gas in galaxy mergers by combining hydrodynamic simulations that include black holes with a three-dimensional, non-local thermodynamic equilibrium (LTE) radiative transfer code. We find that molecular clouds entrained in AGN winds produce an extended CO morphology with significant off-nuclear emission, which may be detectable via contour mapping. Furthermore, kinematic signatures of these molecular outflows are visible in emission-line profiles when the outflow has a large line-of-sight velocity. Our results can help interpret current and upcoming observations of luminous infrared galaxies, as well as provide a …

Molecular Line Emission From Gravitationally Unstable Protoplanetary Disks, Desika Narayanan
Faculty Publications
In the era of high-resolution submillimeter interferometers, it will soon be possible to observe the neutral circumstellar medium directly involved in gas giant planet (GGP) formation at physical scales previously unattainable. In order to explore possible signatures of GGP formation via disk instabilities, we have combined a three-dimensional (3D), nonlocal thermodynamic equilibrium (LTE) radiative transfer code with a 3D, finite differences hydrodynamical code to model molecular emission lines from the vicinity of a 1.4MJ self-gravitating proto-GGP. Here we explore the properties of rotational transitions of the commonly observed dense gas tracer, HCO+. Our main results are as follows: …
Provincial Anthropology, Circumlocution, And The Copious Use Of Everything, Laurie Kain Hart
Provincial Anthropology, Circumlocution, And The Copious Use Of Everything, Laurie Kain Hart
Faculty Publications
Provincial towns are not miniature replicas of national metropolises but centers with their own trajectories of aesthetic and civic development. They operate in a regional context in relation both to the rural villages within their spheres of influence and to international cultural circuits. Inhabitants of peripheral towns in Greece negotiate the challenges of pluralism, modernization, and the hegemony of the nation state in their own social, political, and cultural idioms of accommodation and distancing. A close analysis of the modern history, city planning, and architecture of Florina in Western Greek Macedonia, particularly in the period between WWI and WWII, shows …

The Parkes Multibeam Pulsar Survey: Vi. Discovery And Timing Of 142 Pulsars And A Galactic Population Analysis, Duncan R. Lorimer, A. J. Faulkner, A. G. Lyne, Richard N. Manchester, Fronefield Crawford
Faculty Publications
We present the discovery and follow-up observations of 142 pulsars found in the Parkes 20-cm multibeam pulsar survey of the Galactic plane. These new discoveries bring the total number of pulsars found by the survey to 742. In addition to tabulating spin and astrometric parameters, along with pulse width and flux density information, we present orbital characteristics for 13 binary pulsars which form part of the new sample. Combining these results from another recent Parkes multibeam survey at high Galactic latitudes, we have a sample of 1008 normal pulsars which we use to carry out a determination of their Galactic …
