Global Distribution of Fe K alpha Lines in the Galactic Center Region Observed with the Suzaku Satellite
Galaxy: Center—Inter stellar medium— X-ray spectra
2011/10/9
We have surveyed spatial profiles of the Fe K$\alpha$ lines in the Galactic center diffuse X-rays (GCDX), including the transient region from the GCDX to the Galactic ridge X-ray emission (GRXE), with...
Nonlinear force-free and potential field models of active-region and global coronal fields during the Whole Heliospheric Interval
Nonlinear force-free potential field models
2011/1/13
Between 2008/3/24 and 2008/4/2, the three active regions NOAA active regions 10987, 10988 and 10989 were observed daily by the Synoptic Optical Long-term Investigations of the Sun (SOLIS) Vector Spec...
Global magnetic cycles in rapidly rotating younger suns
Global magnetic cycles rapidly rotating younger suns
2011/1/13
Observations of sun-like stars rotating faster than our current sun tend to exhibit increased magnetic activity as well as magnetic cycles spanning multiple years. Using global simulations in spherica...
Constraints on cosmic-ray propagation models from a global Bayesian analysis
astroparticle physics—diffusion—methods statistical—cosmic rays—ISM general—Galaxy: general
2010/11/9
Research in many areas of modern physics such as, e.g., indirect searches for dark matter and particle acceleration in SNR shocks, rely heavily on studies of cosmic rays (CRs) and associated diffuse e...
Probing the parameter space of HD 49933: a comparison between global and local methods
comparison global local methods
2010/11/16
We present two independent methods for studying the global stellar parameter space (mass M, age, chemical composition X0, Z0) of HD 49933 with seismic data. Using a local minimization and an MCMC algo...
The global dust SED: Tracing the nature and evolution of dust with DustEM
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
The Planck and Herschel missions are currently measuring the farIR-mm emission of dust, which combined with existing IR data, will for the first time provide the full SED of the galactic ISM dust emis...
Global Lorentzian geometry from lightlike geodesics: What does an observer in (2+1)-gravity see?
lightlike geodesics (2+1)-gravity
2010/3/19
We show how an observer could measure the non-local holonomy variables that parametrise the flat Lorentzian 3d manifolds arising as spacetimes in (2+1)-gravity. We consider an observer who emits light...
