Abridged) The far-infrared (FIR) and radio luminosities of star-forminggalaxies are linearly correlated over a very wide range in star formation rate,from normal spirals like the Milky Way to the most intense starbursts. Usingone-zone models of cosmic ray (CR) injection, cooling,

Multi-epoch reverberation mapping of the Seyfert galaxy, NGC 5548, suggeststhat radiation pressure is not strongly biasing the black hole (BH) massesderived for active galactic nuclei (AGNs). The model proposed by Marconi et al.to account for radiation pressure in BH mass

We review the results of a timing analysis of the observations for ten brightX-ray pulsars (with fluxes >100 mCrab in the 20-100 keV energy band) that fellwithin the INTEGRAL field of view from 2003 to 2007. The dependence of thepulse

We present follow-up time-series photometric observations that confirm andextend the results of the significant discovery made by Barlow et al.(2008)that the Hot DQ white dwarfs SDSS J220029.08-074121.5 and SDSSJ234843.30-094245.3 are luminosity variable. These are the second and thirdknown members of

Our model involving cosmic ray acceleration in supernova remnants has beenused to predict cosmic ray intensities over long periods of time on astatistical basis. If, as is highly probable, extensive air showers caused byPeV cosmic rays are needed to initiate

This Letter presents the first results from the observations of LSI +61 303using Large Area Telescope data from the Fermi Gamma-Ray Space Telescopebetween 2008 August and 2009 March. Our results indicate variability that isconsistent with the binary period, with the

The evolution of C and O abundances in the Milky Way can impose strongconstraints on stellar nucleosynthesis and help understanding the formation andevolution of our Galaxy. The aim is to review the measured C and O abundancesin the disk and

As part of our programme to map the large-scale distribution of galaxiesbehind the southern Milky Way, we observed 314 optically-selected,partially-obscured galaxies in the Zone of Avoidance (ZOA) in the Crux andGreat Attractor (GA) regions. The observations were conducted with the

Efficient computation of the quadrupole light deflection for bothstars/quasars and solar system objects within the framework of the baselineGaia relativity model (GREM) is discussed. Two refinements have been achievedwith the goal to improve the performance of the model:-- The quadrupole

This contribution describes the experimental set-up implemented by theLUNASKA project at the Australia Telescope Compact Array (ATCA) to enable theradio-telescope to be used to search for pulses of coherent Cherenkov radiationfrom UHE particle interactions in the Moon with an unprecedented

The lunar Cherenkov technique is a method to use radio-telescopes to detectultra-high energy cosmic rays (CR) and neutrinos ($\nu$). By observing theshort-duration ($\sim$few nanosecond) pulses of coherent Cherenkov radiationemitted from particle cascades via the Askaryan Effect in the Moon's outerlayers

Context : On its asteroseismic side, the initial run of CoRoT was partlydevoted to the solar like star HD49933.The eigenmodes of this F dwarf have beenobserved with unprecedented accuracy.Aims : We investigate quantitatively the impact of changes in the modelingparameters

The low mass X-ray binary and Z source GX 17+2 undergoes infrared K-bandbrightening episodes of at least 3.5 magnitudes. The source of these episodesis not known. Prior published K-band magnitudes and new K-band measurementsacquired between 2006 and 2008 suggest that

The high-peaked BL Lac object Pks2155-304 shows high variability atmultiwavelengths, i.e. from optical up to TeV energies. A giant flare of around1 hour at X-ray and TeV energies was observed in 2006. In this context, it isessential to understand the

The Pierre Auger Observatory is a hybrid detector for ultra-high energycosmic rays. It combines a surface array to measure secondary particles atground level together with a fluorescence detector to measure the developmentof air showers in the atmosphere above the array.

Using our recently improved Monte Carlo evolution code, we study theevolution of the binary fraction in globular clusters. In agreement withprevious N-body simulations, we find generally that the hard binary fraction inthe core tends to increase with time over a

The accelerating expansion of the Universe at recent epochs has called intoquestion the validity of general relativity on cosmological scales. One probeof gravity is a comparison of expansion history of the Universe with thehistory of structure growth via gravitational instability:

Effective collision strengths for forbidden transitions among the 5energetically lowest finestructure levels of O II are calculated in theBreit-Pauli approximation using the R-matrix method. Results are presented forthe electron temperature range 100 to 100 000 K. The accuracy of thecalculations

There is disagreement currently about whether cooling in protoplanetary diskscan be sufficiently fast to induce the formation of gas giant protoplanets viagravitational instabilities. Simulations by our own group and others indicatethat this method of planet formation does not work for
