(Oxford University Press on behalf of the Royal Astronomical Society, 2012-07)We present a new chemodynamical code – RAMSES-CH – for use in simulating the self-consistent evolution of chemical and hydrodynamical properties of galaxies within a fully cosmological framework. We build upon the adaptive ...
-
(American Astronomical Society, 2011-03-01)We present initial results on some of the properties of open clusters NGC 6791 and NGC 6819 derived from asteroseismic data obtained by NASA’s Kepler mission. In addition to estimating the mass, radius, and log g of stars ...
-
(American Astronomical Society, 2010-04-20)We have measured solar-like oscillations in red giants using time-series photometry from the first 34 days of science operations of the Kepler Mission. The light curves, obtained with 30 minute sampling, reveal clear ...
-
(Oxford University Press, 2012-01)Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 km s[superscript −1], and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/d galaxy. We ...
-
(Oxford University Press, 2011-03)In 2009 March the well-studied quasar, PG 0844+349, was discovered with Swift to be in an X-ray weak state. A follow-up XMM–Newton observation several weeks later generated a good-quality spectrum of the source, showing ...
-
(Oxford University Press, 2011-02)Multi-epoch X-ray spectroscopy (0.3–25 keV) of the Seyfert 1.2 galaxy Mrk 79 (UGC3973) spanning nearly 8 yr and a factor of 3 in broad-band flux are analysed. The data are obtained at seven epochs with either XMM–Newton ...
-
(Oxford University Press, 2009-10)We present the results from a monitoring campaign of the Narrow-Line Seyfert 1 galaxy PG 1211+143. The object was monitored with ground-based facilities (UBVRI photometry; from 2007 February to July) and with Swift [X-ray ...
-
(Oxford University Press, 2013-03-11)The narrow-line Seyfert 1 galaxy IRAS 13224−3809 has been observed with XMM–Newton for 500 ks. The source is rapidly variable on time-scales down to a few 100 s. The spectrum shows strong broad Fe − K and L emission ...

Radio-to-[gamma]-ray monitoring of the narrow-line Seyfert 1 galaxy PMN J0948+0022 from 2008 to 2011 (EDP Sciences, 2012-11)We present more than three years of observations at different frequencies, from radio to high-energy [gamma]-rays, of the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z = 0.585). This source is the first NLS1 detected ...
-
(University of Chicago, 1993-06)Large productivity gains have been observed in Chinese agriculture following the transition from collective farming to household contracting. Using a model of mutual monitoring in an egalitarian production team, we estimate ...

(American Astronomical Society, 1999-11-01)A grid of stellar evolution models for Procyon A has been calculated. These models include the best physics available to us (including the latest opacities and equation of state) and are based on the revised astrometric ...
-
(Springer Science+Business Media B.V., 2008-08)The stellar evolution code YREC is outlined with emphasis on its applications to helio- and asteroseismology. The procedure for calculating calibrated solar and stellar models is described. Other features of the code such ...
-
(Royal Astronomical SocietyOxford University Press, 2013-01)Microvariability and Oscillations of STars observations and model analysis of the Herbig Ae star HD 34282 (V1366 Ori) reveal [delta] Scuti pulsations. 22 frequencies are observed, 10 of which confirm those previously ...
-
(Inter-Research, 2005-09-23)Myxobolus bilobus n. sp. (Myxozoa) is described from golden shiner Notemigonus crysoleucas in Algonquin Park, Ontario, Canada. Plasmodia develop at the distal end of gill filaments, where they form a novel-shaped plasmodium ...
-
(Royal Astronomical Society, 2012-12)By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a ...
-
(Royal Astronomical Society, 2012-10)Within a cosmological hydrodynamical simulation, we form a disc galaxy with subcomponents which can be assigned to a thin stellar disc, thick disc and a low-mass stellar halo via a chemical decomposition. The thin- and ...
-
(American Physical Society, 2006-11)The mean square polarizability radii of the proton have been measured for the first time in a virtual-Compton-scattering experiment performed at the MIT-Bates out-of-plane scattering facility. Response functions and ...
-
(American Physical Society, 2009-11)An experimental study of the [superscript 16]O(e,e[superscript 1]K[superscript +][superscript 16][subscript lambda] N reaction has been performed at Jefferson Lab. A thin film of falling water was used as a target. This ...
