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... |

Raga, A. C.; Noriega-Crespo, A.; Gonzalez, R. F.; Velazquez, P. F., 2004, "Models for the infrared cavity of HH 46/47", https://hdl.handle.net/2014/40885, The Astrophysical Journal Supplement Series, 154:346–351, 2004 September, DOI: 10.1086/422639, JPL Open Repository
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... |

Analysis of near-coincident ICESat and RADARSAT imagery shows that the retrieved elevations from the laser altimeter are sensitive to new openings (containing thin ice or open water) in the sea ice cover as well as to surface relief of old and first-year ice. The precision of the... |
