Chandra observation of the edge-on spiral NGC 5775: probing the hot galactic disc/halo connection
individual (NGC 5775) general
2014/12/23
We study the edge-on galaxy NGC 5775, utilizing a 58.2 ks Chandra ACIS-S observation together with complementary Hubble Space Telescope (HST) ACS, Spitzer IRAC and other multi-wavelength data sets. Th...
Quasi periodic oscillations of solar active regions in connection with their flare activity - NoRH observations
Oscillations, Solar Radio Emission Radio Bursts, Association with Flares
2011/9/29
The sunspot-associated sources at the frequency of 17 GHz give information on plasma parameters in the regions of magnetic field about B=2000 G at the level of the chromosphere-corona transition regio...
The connection between missing AGB stars and extended horizontal branches
missing AGB stars extended horizontal branches
2011/1/13
Recent surveys confirm early results about a deficiency or even absence of CN-strong stars on the asymptotic giant branch (AGB) of globular clusters (GCs), although with quite large cluster-to-cluster...
The Ultraviolet-X-ray connection in AGN outflows
X-ray Spectroscopy UV spectroscopy Active Galactic Nuclei absorption lines
2010/11/15
In this paper I review the recent progress in understanding the physics of the gas outflowing from active galactic nuclei and its impact on the surrounding environment, using the combined information ...
A simple connection between the near- and mid-infrared emission of galaxies and their star-formation rates
the near- and mid-infrared emission galaxies
2011/1/10
We have measured the near-infrared colors and the fluxes of individual pixels in 68 galaxies common to the Spitzer Infrared Nearby Galaxies Survey and the Large Galaxy Atlas Survey. Each galaxy was se...
Exploring the connection of weak winds and magnetic fields
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
The theory of radiatively driven winds successfully explains the key points of the stellar winds of hot massive stars. However, there is an apparent break-down of this paradigm at L/Lsun<5.2: the stel...
Probing the accretion disk - jet connection via instabilities in the inner accretion flow. From microquasars to quasars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
We present various instability mechanisms in the accreting black hole systems which might indicate at the connection between the accretion disk and jet. The jets observed in microquasars can have a pe...

On A Possible Connection Between Chandler Wobble And Dark Matter
Chandler wobble Polar motion Dark matter
2010/7/5
Chandler wobble excitation and damping, one of the open problems in geophysics, is treated as a consequence in part of the interaction between Earth and a hypothetical oblate ellipsoid made of dark ma...
