Interactive evolution of multiple water-ice reservoirs on Mars: Insights from hydrogen isotope compositions
Mars water ice isotope atmospheric escape
2017/4/10
Remote sensing data from orbiter missions have proposed that ground ice may currently exist on Mars, although the
volume is still uncertain. Recent analyses of Martian meteorites have suggested that ...
WVU astrophysicists part of gravitational wave search that provides insights into galaxy evolution and mergers
WVU astrophysicists gravitational wave search galaxy evolution and mergers
2016/4/13
On the heels of their participation in the historic research that resulted in the detection of gravitational waves, West Virginia University astrophysicists continue to plow new ground ...
Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light. This important advance was made poss...
Variations in 24-mu m morphologies among galaxies in the Spitzer Infrared Nearby Galaxies Survey: new insights into the Hubble sequence
ISM structure
2014/12/23
To study the distribution of star formation and dust emission within nearby galaxies, we measured five morphological parameters in the 3.6- and 24-μm wavebands for 65 galaxies in the Spitzer Infrared ...
New insights into galaxy structure from galphat– I. Motivation, methodology and benchmarks for Sérsic models
new galaxy image decomposition tool galphat
2014/12/20
We introduce a new galaxy image decomposition tool, galphat (GALaxy PHotometric ATtributes), which is a front-end application of the Bayesian Inference Engine (bie), a parallel Markov chain Monte Carl...
Holographic Dark Energy Characterized by the Total Comoving Horizon and Insights to Cosmological Constant and Coincidence Problem
Holographic Dark Energy the Total Comoving Horizon Insights Cosmological Constant Coincidence Problem
2012/2/21
The observed acceleration of the present universe is shown to be well explained by the holographic dark energy characterized by the total comoving horizon of the universe ($\eta$HDE). It is of interes...
Insights on the Formation, Evolution, and Activity of Massive Galaxies From Ultra-Compact and Disky Galaxies at z=2-3
Insights Formation Evolution Activity Massive Galaxies Disky Galaxies
2011/10/9
We present our results on the structure and activity of massive galaxies at z=1-3 using one of the largest (166 with M_star>=5e10 M_sun) and most diverse samples of massive galaxies derived from the G...
A Spitzer IRS Survey of NGC 1333: Insights into disk evolution from a very young cluster
Spitzer IRS Survey Insights evolution cluster
2011/10/10
We report on the {\lambda} = 5-36{\mu}m Spitzer Infrared Spectrograph spectra of 79 young stellar objects in the very young nearby cluster NGC 1333. NGC 1333's youth enables the study of early protopl...
Star Formation in Collision Debris: Insights from the modeling of their Spectral Energy Distribution
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/28
During galaxy-galaxy interactions, massive gas clouds can be injected into the intergalactic medium which in turn become gravitationally bound, collapse and form stars, star clusters or even dwarf gal...
The rotational excitation of HCN and HNC by He: New insights on the HCN/HNC abundance ratio in molecular clouds
Molecular data Molecular processes scattering
2010/3/9
Modeling of molecular emission from interstellar clouds requires the calculation of rates for excitation by collisions with the most abundant species. The present paper focuses on the calculation of r...
New Insights into Dissipation in the Electron Layer During Magnetic Reconnection
New Insights Magnetic Reconnection Electron Layer
2010/3/8
Detailed comparisons are reported between laboratory observations of electron-scale dissipation layers near a reconnecting X-line and direct two-dimensional full-particle simulations. Many experimenta...
