We report the detection of CO(2r1) emission from the ultraluminous infrared galaxy (ULIRG) GOODS z p 1.2 J123634.53ϩ621241.3 (also known as the submillimeter galaxy GN 26). These observations represent the first discovery of high-redshift CO emission using the new Combined Array for Research in Millimeter-Wave Astronomy (CARMA). Of all high-redshift ()(More)
A Connected Dominating Set (CDS) of the graph representing a Wireless Sensor Network can be used as a virtual backbone for routing in the network. Since sensor nodes are constrained by limited on-board batteries, it is desirable to have a small CDS for the network. However, constructing a minimum size CDS has been shown to be a NP-hard problem.

We present high spatial resolution (5.1 ′′ × 2.7 ′′) Owens Valley Radio Observatory (OVRO) millimeter array observations of HCN (J=1-0) and HCO + (J=1-0) emission in the inner 3 pc of the Galaxy (0.04 pc ∼ 1 ′′). The HCN and HCO + emission of the Circumnuclear Disk (CND) is distributed in a well-defined ring with a peak at a radius of 1.6 pc. The observed(More)
A New High Resolution CO Map of the inner 2. ABSTRACT The Owens Valley mm-Array has been used to map the CO 1–0 emission in the inner 2 ′ .5 of the grand design spiral galaxy M51 at 2 ′′ − 3 ′′ resolution. These new images reveal the molecular spiral arms with unprecedented clarity – the emission in the two major arms (NE and SW) originates from(More)
We present near-infrared images obtained with the HST NICMOS camera for a sample of 9 luminous (LIGs: L IR (8 − 1000µm) ≥ 10 11 L ⊙) and 15 ultra-luminous (ULIGS: L IR ≥ 10 12 L ⊙) infrared galaxies. The sample includes representative systems classified as warm (f 25µm /f 60µm > 0.2) and cold (f 25µm /f 60µm ≤ 0.2) based on the mid-infrared colors and(More)
We present new aperture synthesis CO maps of the Antennae (NGC 4038/39) obtained with the Caltech Millimeter Array. These sensitive images show molecular emission associated with the two nuclei and a partial ring of star formation to the west of NGC 4038, as well as revealing the large extent of the extra-nuclear region of star formation (the " overlap(More)

We report 0. ′′ 5 × 0. ′′ 9 resolution, interferometric observations of the 1.3 mm CO J=2→1 line in the infrared luminous galactic merger NGC 6240 2. About half of the CO flux is concentrated in a rotating but highly turbulent, thick disk structure centered between the two radio and near-infrared nuclei. A number of gas features connect this ∼500 pc(More)
