Improved Cosmological Constraints from Gravitational Lens Statistics
We combine the Cosmic Lens All-Sky Survey (CLASS) with new Sloan Digital Sky Survey (SDSS) data on the local velocity dispersion distribution function of E/S0 galaxies, � (� ), to derive lensExpand

The drying of Titan's dunes: Titan's methane hydrology and its impact on atmospheric circulation
[1] We explore the effect of a finite reservoir of methane on Titan's atmospheric circulation, precipitation patterns, and surface methane content. We develop a soil model that accounts for theExpand

The dynamics behind Titan's methane clouds
We present results of an axisymmetric global circulation model of Titan with a simplified suite of atmospheric physics forced by seasonally varying insolation. The recent discovery of midlatitudeExpand

Axisymmetric, nearly inviscid circulations in non-condensing radiative-convective atmospheres
We study the steady-state axisymmetric circulation of nearly inviscid, compressible atmospheres with no condensible component. Assuming simplified non-grey radiative transfer and instantaneousExpand

The transition to superrotation in terrestrial atmospheres
[1] We show that by changing a single nondimensional number, the thermal Rossby number, global atmospheric simulations with only axisymmetric forcing pass from an Earth-like atmosphere to aExpand

THE MECHANICAL GREENHOUSE: BURIAL OF HEAT BY TURBULENCE IN HOT JUPITER ATMOSPHERES
The intense irradiation received by hot Jupiters suppresses convection in the outer layers of their atmospheres and lowers their cooling rates. “Inflated” hot Jupiters, i.e., those with anomalouslyExpand

Modern and glacial tropical snowlines controlled by sea surface temperature and atmospheric mixing
During the Last Glacial Maximum, tropical glacier snowlines were lower than expected, based on estimates of tropical sea surface temperatures. Sea surface temperature reconstructions suggest theExpand

Spontaneous Superrotation and the Role of Kelvin Waves in an Idealized Dry GCM
The nondimensional parameter space of an idealized dry primitive equation model is explored to find superrotating climate states. The model has no convective parameterization and is forced using aExpand

Locally enhanced precipitation organized by planetary-scale waves on Titan
Saturn’s moon Titan exhibits an active weather cycle that involves methane. An analysis of cloud observations and simulations with a general circulation model reveals that convection in Titan’sExpand

Elastic ice shells of synchronous moons: Implications for cracks on Europa and non-synchronous rotation of Titan
A number of synchronous moons are thought to harbor water oceans beneath their outer ice shells. A subsurface ocean frictionally decouples the shell from the interior. This has led to proposals thatExpand
