Durden, S. L.; Meagher, J. P.; Haddad, Z. S., 2004, "Satellite observations of spatial and interannual variability of lightning and radar reflectivity", https://hdl.handle.net/2014/40363, Geophysical Research Letters, Vol. 31, L18111, doi:10.1029/2004GL020384, 2004, JPL Open Repository
The authors use satellite data to examine the relationship between lightning and upper-level radar reflectivity. They find correlations between average flash rates and upper-level reflectivities over both land and ocean, although both flash rates and reflectivities are much lower... |

Observed properties of the magnetic field in the outer heliosphere are generally well described by the Parker model but evidence has accumulated of significant departures in the components and field magnitude. The radial component is independent of solar latitude at both solar mi... |

Opher, M.; Liewer, P. C.; Velli, M.; Gombosi, T. I.; Manchester, W.; DeZeeuw, D. L.; Toth, G.; Sokolov, I., 2004, "Magnetic effects change our view of the Heliosheath", https://hdl.handle.net/2014/39209, AIP Conference Proceedings vol.719, no.1, 105-110, JPL Open Repository
In this paper we review these recent results, and present an additional simulation with constant neutral atom background. In this case the jet is still present but with reduced intensity. Further study, e.g., including neutrals and the tilt of the solar rotation from the magnetic... |

Haddad, Ziad S.; Meagher, Jonathan P.; Adler, Robert F.; Smith, Eric A.; Im, Eastwood; Durden, Stephen L., 2004, "Global variability of precipitation according to the Tropical Rainfall Measuring Mission", https://hdl.handle.net/2014/39276, Journal of Geophysical Research, Vol. 109, D17103, doi:10.1029/2004JD004607, September 11, 2004., JPL Open Repository
Numerous studies have documented the effect of El Nino-Southern Oscillation (ENSO) on rainfall in many regions of the globe. The question of whether ENSO is the single most important factor in interannual rainfall variability has received less attention, mostly because the kind o... |

We carried out direct measurement of the fraction of dusty sources in a sample of extremely red galaxies with (R - Ks) ≥ 5:3 mag and Ks < 20:2 mag, using 24 µm data from the Spitzer Space Telescope. Combining deep 24 µm Ks- and R-band data over an area of ~64 arcmin² in ELAIS N1... |

We investigate extremely red objects (EROs) using near- and mid-infrared observations in five passbands (3.6 to 24 μm) obtained from the Spitzer Space Telescope, and deep ground-based R and K imaging. The great sensitivity of the Infrared Array Camera (IRAC) camera allows us to d... |

Nguyen, Hien T.; Kallivayalil, Nitya; Werner, Michael W.; Alcock, Charles; Patten, Brian M.; Stern, Daniel, 2004, "Spitzer Space Telescope Observations of the aftermath of Microlensing Event MACHO-LMC-5", https://hdl.handle.net/2014/40900, The Astrophysical Journal Supplement Series, 154:266–270, 2004 September, JPL Open Repository
We have carried out photometry of the microlensing event MACHO-LMC-5 with Spitzer Infrared Array Camera (IRAC) 10 years after the magnification of the LMC source star was recorded. This event is unique in the annals of gravitational microlensing: the lensing star itself has been... |

We have modeled the limb-brightened cavity seen in the new Spitzer Space Telescope IR images of the southwest lobe of HH 46/47 as the bow shock driven by an outflow from a young, low-mass star. We present models in which the outflow is a perfectly collimated, straight jet, models... |

We present the first rest-frame ~4 μm detection of a Lyman break galaxy. The data were obtained using the 16 μm imaging capability of the Spitzer Infrared Spectrograph. The target object, J134026.44+634433.2, is an extremely luminous Lyman break galaxy at z = 2:79, first identifi... |
