Warm Spitzer Observations of Three Hot Exoplanets: Xo-4b, Hat-p-6b, and Hat-p-8b
(American Astronomical Society, 2012)We analyze Warm Spitzer/Infrared Array Camera observations of the secondary eclipses of three planets, XO-4b, HAT-P-6b, and HAT-P-8b. We measure secondary eclipse amplitudes at 3.6 mu m and 4.5 mu m for each target. XO-4b ... -
Warm Spitzer Photometry of the Transiting Exoplanets Corot-1 and Corot-2 at Secondary Eclipse
(American Astronomical Society, 2011)We measure secondary eclipses of the hot giant exoplanets CoRoT-1 at 3.6 and 4.5 mu m, and CoRoT-2 at 3.6 mu m, both using Warm Spitzer. We find that the Warm Spitzer mission is working very well for exoplanet science. For ... -
Warm spritzer photometry of three hot Jupiters: HAT-P-3b, HAT-P-4b and HAT-P-12b
(IOP Publishing, 2013)We present Warm Spitzer/IRAC secondary eclipse time series photometry of three short-period transiting exoplanets, HAT-P-3b, HAT-P-4b and HAT-P-12b, in both the available 3.6 and 4.5 µm bands. HAT-P-3b and HAT-P-4b are ... -
Warmth and competence as distinct dimensions of value in social emotions
(Cambridge University Press (CUP), 2017)Gervais & Fessler's analysis collapses across two orthogonal dimensions of social value to explain contempt: relational value, predicted by cooperation, and agentic value, predicted by status. These dimensions interact to ... -
Warning Signals for Eruptive Events in Spreading Fires
(Proceedings of the National Academy of Sciences, 2015)Spreading fires are noisy (and potentially chaotic) systems in which transitions in dynamics are notoriously difficult to predict. As flames move through spatially heterogeneous environments, sudden shifts in temperature, ... -
Warped \(AdS_3\) Black Holes
(Institute of Physics, 2009)Three dimensional topologically massive gravity (TMG) with a negative cosmological constant \(-\ell^{-2}\) and positive Newton constant \(G\) admits an \(AdS_3\) vacuum solution for any value of the graviton mass \(\mu\). ... -
Warped \(AdS_3\)/Dipole-CFT Duality
(Springer-Verlag, 2012)String theory contains solutions with \(SL(2, \mathbb{R})_R \times U(1)_L\)-invariant warped \(AdS_3\) \((WAdS_3)\) factors arising as continuous deformations of ordinary \(AdS_3\) factors. We propose that some of these ... -
A Warped Accretion Disk and Wide‐Angle Outflow in the Inner Parsec of the Circinus Galaxy
(IOP Publishing, 2003)We present the first VLBI maps of H2O maser emission (λ1.3 cm) in the nucleus of the Circinus Galaxy, constructed from data obtained with the Australia Telescope Long Baseline Array. The maser emission traces a warped, ... -
Warped AdS3/dipole-CFT duality
(Springer Nature, 2012)String theory contains solutions with SL(2, R)R × U(1)L-invariant warped AdS3 (WAdS3) factors arising as continuous deformations of ordinary AdS3 factors. We propose that some of these are holographically dual to the IR ... -
Warped dipole completed, with a tower of Higgs bosons
(Springer Science + Business Media, 2015)In the context of warped extra-dimensional models which address both the Planck-weak- and flavorhierarchies of the Standard Model (SM), it has been argued that certain observables can be calculated within the 5D effective ... -
Wartime in the history of economic thought: episodes in European history
(Informa UK Limited, 2023-10-13)The paper is concerned with war in the history of economic thought. It looks at disputes about abstraction versus historicism over the long 19th century, in relation to war and the state. It then looks at the historical ... -
Was 1974 the End of Music History? Universalism, cybernetics, and the International Conference of New Musical Notation
(Routledge, 2022-03-22)In this chapter, I examine the underlying principles and historiographical consequences of the Index of New Musical Notation (1970) and its associated event, the International Conference on New Musical Notation (1974 Ghent, ... -
Was the Universe Reionized at Redshift 10?
(American Astronomical Society, 2005)Recently, Pello and coworkers claimed to have discovered a galaxy at a redshift z = 10 and identified a feature in its spectrum with a hydrogen Lyalpha emission line. If this identification is correct, we show that the ... -
Water Activity and the Challenge for Life on Early Mars
(American Association for the Advancement of Science, 2008)In situ and orbital exploration of the martian surface has shown that acidic, saline liquid water was intermittently available on ancient Mars. The habitability of these waters depends critically on water activity ... -
Water and Thermal Diffusivity in a Lipid-Water Smectic Phase
(Elsevier, 1978)We report the first application of light scattering to measurement of the hydrodynamic relaxation of inhomogeneities in water concentration within a multilamellar, or smectic A, phospholipid water system (dipalmitoyl) ... -
Water Diffusion and Fracture Behavior in Nano-Porous Low-K Dielectric Film Stacks
(American Institute of Physics, 2009)Among various low-dielectric constant (‘low-k’) materials under development, organosilicate glasses (OSG) containing nanometer-size pores are leading candidates for use as intra-metal dielectrics in future microelectronics ... -
Water Formation During the Epoch of First Metal Enrichment
(American Astronomical Society, 2015)We demonstrate that high abundances of water vapor could have existed in extremely low metallicity (10(-3) solar) partially shielded gas during the epoch of first metal enrichment of the interstellar medium of galaxies at ... -
Water loss from terrestrial planets with \(CO_2\)-rich atmospheres
(IOP Publishing, 2013)Water photolysis and hydrogen loss from the upper atmospheres of terrestrial planets is of fundamental importance to climate evolution but remains poorly understood in general. Here we present a range of calculations we ... -
Water Networks Contribute to Enthalpy/Entropy Compensation in Protein–Ligand Binding
(American Chemical Society, 2013)The mechanism (or mechanisms) of enthalpy–entropy (H/S) compensation in protein–ligand binding remains controversial, and there are still no predictive models (theoretical or experimental) in which hypotheses of ligand ... -
Water on Mars and the Prospect of Martian Life
(Mineralogical Society of America, 2006)Evidence of water on Mars dates back to the first observations of channeled landscapes made by Mariner 9 and Viking. More recent images from Mars Global Surveyor and Mars Express strikingly confirm that fluids have E ...
