Venus transit 2004: Illustrating the capability of exoplanet transmission spectroscopy
Planets and satellites: atmospheres – Planets and satellites: composition – Planets and satellites: detection – Radiative transfer – Techniques: spectroscopic
2011/10/11
The transit of Venus in 2004 offered the rare possibility to remotely sense a well-known planetary atmosphere using ground-based observations for absorption spectroscopy. Transmission spectra of Venus...
Abundances in planetary nebulae: NGC1535, NGC6629, He2-108, and Tc1
ISM: abundances – planetary nebulae: individual: NGC1535 & Tc 1 (& IC1266) & NGC6629 & He2-108 – Infrared: ISM: lines and bands
2011/10/12
The aim of the paper is to determine abundances in a group of PNe with uniform morphology. The PNe discussed are circular excited by rather low-temperature central stars. The relation between abundanc...
We consider inflation within the context of what is arguably the simplest non-metric extension of Einstein gravity. There non-metricity is described by a single graviscalar field with a non-minimal ki...
Gravitational instability of the primordial plasma: anisotropic evolution of structure seeds
Gravitational instability primordial plasma: anisotropic evolution
2011/10/10
We study how the presence of a background magnetic field, of intensity compatible with current observation constraints, affects the linear evolution of cosmological density perturbations at scales bel...
The Nature of Double-Peaked [O III] Active Galactic Nuclei
Nature Double-Peaked [O III] Active Galactic Nuclei
2011/10/11
Active galactic nuclei (AGNs) with double-peaked [O III] lines are suspected to be sub-kpc or kpc-scale binary AGNs. However, pure gas kinematics can produce the same double-peaked line profile in spa...
Intensity Mapping of the [CII] Fine Structure Line during the Epoch of Reionization
Intensity Mapping Fine Structure Line during Epoch Reionization
2011/10/11
The atomic CII fine-structure line is one of the brightest lines in a typical star-forming galaxy spectrum with a luminosity ~ 0.1% to 1% of the bolometric luminosity. It is potentially a reliable tra...
We introduce bilayer networks in this paper to study the coupled air-sea systems. It proved true that the framework of bilayer networks is powerful for studying the statistical topology structure and ...
Searching for Saturn's Dust Swarm: Limits on the size distribution of Irregular Satellites from km to micron sizes
Solar System: satellites
2011/10/8
We describe a search for dust created in collisions between the Saturnian irregular satellites using archival \emph{Spitzer} MIPS observations. Although we detected a degree scale Saturn-centric exces...
We present our temporal and spectral analyses of 29 bursts from SGR J0501+4516, detected with the Gamma-ray Burst Monitor onboard the Fermi Gamma-ray Space Telescope during the 13 days of the source a...
In the context of the geometrical analysis of weakly non Gaussian CMB maps, the 2D differential extrema counts as functions of the excursion set threshold is derived from the full moments expansion of...
The current state of the art in the modeling of pulsar magnetospheres invokes either the vacuum or force-free limits for the magnetospheric plasma. Neither of these limits can simultaneously account f...
AXIOM: Advanced X-ray Imaging Of the Magnetosphere
X-rays. Space telescope. Space plasma instrumentation Magnetometer Techniques:Imaging spectroscopy plasma field analysers
2011/9/27
Planetary plasma and magnetic field environments can be studied by in situ measurements or by remote sensing. While the former provide precise information about plasma behaviour, instabilities and dyn...
Paper Productivity of Ground-based Large Optical Telescopes from 2000 to 2009
history and philosophy of astronomy — sociology of astronomy — astronomical data bases: miscellaneous
2011/9/27
We present an analysis of the scientific ("refereed") paper productivity of the current largest (diameter >8 m) ground-based optical(-infrared) telescopes during the ten year period from 2000 to 2009....
"High-resolution", or "long-baseline", science with the SKA and its precursors covers a broad range of topics in astrophysics. In several research areas, the coupling between improved brightness sensi...
