A Spitzer/IRAC Census of the Asymptotic Giant Branch Populations in Local Group Dwarfs. I. WLM
Dale C. Jackson, Evan D. Skillman, Robert D. Gehrz +2
We present Spitzer/IRAC observations at 3.6 and 4.5 microns along with optical data from the Local Group Galaxies Survey to investigate the evolved stellar population of the Local…
Spitzer IRAC Images and Sample Spectra of Cassiopeia A's Explosion
J. A. Ennis, L. Rudnick, W. T. Reach +5
We present Spitzer IRAC images, along with representative 5.27 to 38.5 micron IRS spectra of the Cassiopeia A supernova remnant. We find that various IRAC channels are each most se…
A Search for Deep Impact's Large Particle Ejecta
Michael S. Kelley, William T. Reach, Charles E. Woodward
The Deep Impact encounter with the nucleus of 9P/Tempel ejected small grains (a <~ 10 micron) into the comet's coma, evidenced by thermal emission from small dust grains at mid-inf…
Velocity Distributions from Nonextensive Thermodynamics
Eric I. Barnes, Liliya L. R. Williams, Arif Babul +1
There is no accepted mechanism that explains the equilibrium structures that form in collisionless cosmological N-body simulations. Recent work has identified nonextensive thermody…
Coupled Variations of Fundamental Couplings and Primordial Nucleosynthesis
Alain Coc, Nelson J. Nunes, Keith A. Olive +2
The effect of variations of the fundamental nuclear parameters on big-bang nucleosynthesis are modeled and discussed in detail taking into account the interrelations between the fu…
Two strong-lensing clusters confront universal dark-matter profiles
P. Saha, J. I. Read, L. L. R. Williams
In the galaxy clusters SSDS J1004+411 and ACO 1689, a large number of multiply-imaged background objects have recently been observed. We use these data to map the projected mass di…
