Ionospheric disturbances generated by different natural processes and by human activity in Earth plasma environment
ionosphere Earth plasma environment
2015/9/14
The magnetosphere-ionosphere-thermosphere subsystem is strongly coupled via the electric field, particle precipitation, heat flows and small scale interaction. Satellites in situ measurements and grou...
Molecular environment and thermal X-ray spectroscopy of the semicircular young composite supernova remnant 3C 396
ISM individual (3C 396 G39.2− 0.3) – ISM molecules – supernova remnants
2010/11/15
We have investigated the molecular gas environment of the semicircular composite supernova rem-
nant (SNR) 3C 396 in multiwavelengths and performed a Chandra spatially resolved thermal X-ray
spectro...
The Effect of Environment on Shear in Strong Gravitational Lenses
gravitational lensing strong
2010/11/15
Using new photometric and spectroscopic data in the fields of nine strong gravitational lenses that lie in galaxy groups, we analyze the effects of both the local group environment and line-of-sight g...
The geometry of the filamentary environment of galaxy clusters
geometry filamentary environment galaxy clusters
2010/11/10
We construct a filament catalogue using an extension of the halo based filament finder
of Zhang et al. (2009), in a 250 Mpc/h side N-body simulation, and study the prop-
erties of filaments ending u...
Optical multiband surface photometry of a sample of Seyfert galaxies. I. Large-scale morphology and local environment analysis of matched Seyfert and inactive galaxy samples
galaxies Seyfert – galaxies structure – techniques image processing – techniques photometric
2010/11/12
Context. Parallel analysis of the large-scale morphology and local environment of matched active and control galaxy samples plays an important role in studies of the fueling of active galactic nuclei.
The evolution of massive binaries in a dense stellar cluster environment
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/5
Massive stars are among the most important objects in the Universe and many (most?) of them are formed in binaries. A selection of observational and theoretical facts that illustrate the importance of...
Bar fraction in lenticular galaxies: dependence on luminosity and environment
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the SDSS-DR 7 and 2MASS in optical and near-infrared bands, respectively. We found a bar in 15% of the lenticul...
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star beta Cep using the spec...
Dependence of Star Formation Activity On Stellar Mass and Environment From the Redshift One LDSS-3 Emission Line Survey (ROLES)
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Using the sample from the \it Redshift One LDSS3 Emission line Survey \rm (ROLES), we probe the dependence of star formation rate (SFR) and specific star formation rate (sSFR) as a function of stellar...
Galactic Coronae in the Intracluster Environment: Semi-confined Stellar-feedback-driven Outflows
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
Recently X-ray observations have shown the common presence of compact galactic coronae around intermediate-mass spheroid galaxies embedded in the intracluster/intragroup medium (ICM). We conduct 2-D h...
