2011/10/20
Icy grain mantles are commonly observed through infrared spectroscopy toward dense clouds, cloud cores, protostellar envelopes and protoplanetary disks. Up to 80% of the available oxygen, carbon and n...
Emission Measure Distribution and Heating of Two Active Region Cores
Emission Measure Distribution Heating Active Region Cores
2011/10/13
Using data from the Extreme-ultraviolet Imaging Spectrometer aboard Hinode, we have studied the coronal plasma in the core of two active regions. Concentrating on the area between opposite polarity mo...
Chemical Variation in Molecular Cloud Cores in the Orion A Cloud
Chemical Variation Molecular Cloud Cores the Orion A Cloud
2011/1/10
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the Orion A GMC for the ...
The central slope of dark matter cores in dwarf galaxies: Simulations vs. THINGS
Galaxies dark matter halos – galaxies cosmological N-body+SPH simulations –galaxies kinematics and dynamics
2010/11/15
We make a direct comparison of the derived dark matter (DM) distributions between hydrody-
namical simulations of dwarf galaxies assuming a CDM cosmology and the observed dwarf galaxies sample from ...
CS Lines Profiles in Hot Cores
astrochemistry—line profiles—methods numerical—stars formation—ISM
2010/11/11
We present a theoretical study of CS line profiles in archetypal hot cores. We provide estimates of line fluxes from the CS(1-0) to the CS(15-14) transitions and present the temporal variation of thes...
Cores and Cusps in Warm Dark Matter Halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The apparent presence of large core radii in Low Surface Brightness galaxies has been claimed as evidence in favor of warm dark matter. Here we show that WDM halos do not have cores that are large fra...
Star formation in the Taurus filament L1495: From Dense Cores to Stars
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We present a study of dense structures in the L1495 filament in the Taurus Molecular Cloud and examine its star-forming properties. In particular we construct a dust extinction map of the filament usi...
Gemini/GMOS Spectroscopy of 26 Strong Lensing Selected Galaxy Cluster Cores
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We present results from a spectroscopic program targeting 26 strong lensing cluster cores that were visually identified in the Sloan Digital Sky Survey (SDSS) and the Second Red-Sequence Cluster Surve...
Hadronic- and electromagnetic cores of air-showers observed by hybrid experiments at high mountains
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/4
Characteristics of the high energy families (bundle of high energy e, gamma) and hadrons in the air-showers detected in the hybrid experiment together with emulsion chamber and AS-array at Mt.Chacalta...
