Multiwavelength Observations of the Blazar Mrk 421 in December 2002 and January 2003
P. Rebillot, M. Aller, H. Aller +5
We report on a multiwavelength campaign on the TeV gamma-ray blazar Markarian (Mrk) 421 performed during December 2002 and January 2003. These target of opportunity observations we…
Simple, Accurate, Approximate Orbits in the Logarithmic and a Range of Power-Law Galactic Potentials
Curtis Struck
Curves in a family derived from powers of the polar coordinate formula for ellipses are found to provide good fits to bound orbits in a range of power-law potentials. This range in…
Condensation temperature trends among stars with planets
Guillermo Gonzalez
Results from detailed spectroscopic analyses of stars hosting massive planets are employed to search for trends between abundances and condensation temperatures. The elements C, S,…
Galaxy Collisions - Dawn of a New Era
Curtis Struck
The study of colliding galaxies has progressed rapidly in the last few years, driven by observations with powerful new ground and space-based instruments. These instruments have us…
Cosmic-ray Acceleration at Ultrarelativistic Shock Waves: Effects of a "Realistic" Magnetic Field Structure
Jacek Niemiec, Michal Ostrowski
First-order Fermi acceleration processes at ultrarelativistic shocks are studied with Monte Carlo simulations. The accelerated particle spectra are derived by integrating the exact…
Non-thermal high-energy emission from colliding winds of massive stars
A. Reimer, M. Pohl, O. Reimer
Colliding winds of massive star binary systems are considered as potential sites of non-thermal high-energy photon production. This is motivated merely by the detection of synchrot…
Particle Acceleration at High- Shock Waves
Jacek Niemiec
First-order Fermi acceleration processes at ultrarelativistic shocks are studied with Monte Carlo simulations. The accelerated particle spectra are obtained by integrating the exac…
Beyond linearized cosmology
Dirk Puetzfeld
We comment on the necessity of a unified approximative scheme within relativistic cosmology which would allow us to classify different cosmological models in a systematic way. We a…
The grazing encounter between IC 2163 and NGC 2207: Pushing the limits of observational modeling
Curtis Struck, Michele Kaufman, Elias Brinks +3
We present numerical hydrodynamical models of the collision between the galaxies IC 2163 and NGC 2207. These models extend the results of earlier work where the galaxy discs were m…
A Very High Energy Gamma-Ray Spectrum of 1ES 2344+514
M. Schroedter, H. M. Badran, J. H. Buckley +26
The BL Lacertae (BL Lac) object 1ES 2344+514 (1ES 2344), at a redshift of 0.044, was discovered as a source of very high energy (VHE) gamma rays by the Whipple Collaboration in 199…
The Near Infrared Background: Interplanetary Dust or Primordial Stars?
Eli Dwek, Richard G. Arendt, Frank Krennrich
The intensity of the diffuse ~ 1 - 4 micron sky emission from which solar system and Galactic foregrounds have been subtracted is in excess of that expected from energy released by…
Is There an Imprint of Primordial Stars in the Tev Gamma-Ray Spectrum of Blazars?
Eli Dwek, Frank Krennrich, Richard G. Arendt
The 1 - 5 micron diffuse sky emission from which local foreground emission from the solar system and the Galaxy have been subtracted exceeds the brightness that can be attributed t…
Using Spitzer Colors as Diagnostics of Star Formation Regions: The Interacting Galaxy Arp 107
Beverly J. Smith, C. Struck, P. N. Appleton +3
We present Spitzer infrared imaging of the peculiar galaxy pair Arp 107, and compare with an optical H-alpha map and a numerical model of the interaction. The [3.6 micron] - [4.5 m…
The light curve of the semiregular variable L2 Puppis: II. Evidence for solar-like excitation of the oscillations
T. R. Bedding, L. L. Kiss, H. Kjeldsen +4
We analyse visual observations of the pulsations of the red giant variable L2 Pup. The data cover 77 years between 1927 and 2005, thus providing an extensive empirical base for cha…
Cosmological nonlinear hydrodynamics with post-Newtonian corrections
Jai-chan Hwang, Hyerim Noh, Dirk Puetzfeld
The post-Newtonian (PN) approximation, based on the assumptions of weak gravitational fields and slow motions, provides a way to estimate general relativistic effects in the fully…
A Multi-wavelength View of the TeV Blazar Markarian 421: Correlated Variability, Flaring, and Spectral Evolution
M. Blazejowski
We report results from a multi-wavelength monitoring campaign on Mrk 421 over the period of 2003-2004. The source was observed simultaneously at TeV and X-ray energies, with suppor…
Secular Evolution in Mira Variable Pulsations
M. R. Templeton, J. A. Mattei, L. A. Willson
Stellar evolution theory predicts that asymptotic giant branch stars undergo a series of short thermal pulses that significantly change their luminosity and mass on timescales of h…
Upper Limits on the Extragalactic Background Light from the Gamma-Ray Spectra of Blazars
M. Schroedter
The direct measurement of the extragalactic background light (EBL) is difficult at optical to infrared wavelengths because of the strong foreground radiation originating in the Sol…
Habitable Zones in the Universe
G. Gonzalez
Habitability varies dramatically with location and time in the universe. This was recognized centuries ago, but it was only in the last few decades that astronomers began to system…
Abundance Analyses of Field RV Tauri Stars, VI: An Extended Sample
Sunetra Giridhar, David L. Lambert, Bacham E. Reddy +2
An abundance analysis is presented and discussed for a sample of 14 RV Tauri stars. The present abundance data and those from our previous papers and by other workers are combined…
