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...
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...
