We present the first detection and mapping of the HD 32297 debris disk at 1.3 mm with the Combined Array for Research in Millimeter-wave Astronomy (CARMA). With a subarcsecond beam, this detection represents the highest angular resolution (sub)mm debris disk observation made to date. Our model fits to the spectral energy distribution from the CARMA flux and new Spitzer MIPS photometry support t...
Recent studies revealed layers of enhanced aerosol scattering in the upper troposphere and lower stratosphere over Asia (Asian Tropopause Aerosol Layer (ATAL)) and North America (North American Tropospheric Aerosol Layer (NATAL)). We use a sectional aerosol model (Community Aerosol and Radiation Model for Atmospheres (CARMA)) coupled with the Community Earth System Model version 1 (CESM1) to ex...
The molecular complex containing BCL10 and CARMA [CARD (caspase recruitment domain)-containing MAGUK (membrane-associated guanylate kinase)] proteins has recently been identified as a key component in the signal transduction pathways that regulate activation of the transcription factor NF-kappaB (nuclear factor kappaB) in lymphoid and non-lymphoid cells. Assembly of complexes containing BCL10 a...
We present dust opacity spectral indexes (β) of the youngest protostellar systems (so-called Class 0 sources), L1448 IRS 2, L1448 IRS 3, and L1157, obtained between the λ = 1.3 mm and 2.7 mm continua, using the Combined Array for Research in Millimeter-wave Astronomy (CARMA). The unprecedented compact configuration and image fidelity of CARMA allow a better detection of the dust continuum emiss...
This paper is devoted to the characterization of an extended family of CARMA (continuous-time autoregressive moving average) processes that are solutions of stochastic differential equations driven by white Lévy innovations. These are completely specified by: (1) a set of poles and zeros that fixes their correlation structure, and (2) a canonical infinitely-divisible probability distribution th...
We report the detection of the Sunyaev-Zel’dovich (SZ) effect of galaxy cluster XLSSU J021744.1−034536, using 30 GHz CARMA data. This cluster was discovered via its extended X-ray emission in the XMM-Newton Large Scale Structure survey, the precursor to the XXL survey. It has a photometrically determined redshift z = 1.91 −0.21, making it among the most distant clusters known, and nominally the...
Abstract We have combined laboratory, modeling, and observational efforts to investigate the chemical microphysical processes leading formation of cloud system that formed at an unusually high altitude (>250 km) over Titan’s south pole after northern spring equinox. present here a study focused on C 6 H ice clouds 87°S. As first step our synergistic approach, we measured, for time, equilibri...
