(IOP Publishing Limited, 2012-12)A photometric UBV survey is presented for 610 stars in a region surrounding the Cepheid AQ Puppis and centered southwest of the variable, based upon photoelectric measures for 14 stars and calibrated iris photometry of ...
-
(Wiley-Blackwell, 2012-09)The H2 is an obligate by-product of N-fixation. Recycling of H2 through uptake hydrogenase (Hup) inside the root nodules of leguminous plants is often considered an advantage for plants. However, many ...
-
(EDP Sciences, 2012-04)Aims. We examine radial and vertical metallicity gradients using a suite of disk galaxy hydrodynamical simulations, supplemented with two classic chemical evolution approaches. We determine the rate of change of gradient ...
-
(Public Library of Science, 2014-10-31)Cupin superfamily of proteins, including germin and germin-like proteins (GLPs) from higher plants, is known to play crucial roles in plant development and defense. To date, no systematic analysis has been conducted in ...
-
(Public Library of Science, 2014-06-30)Green roof ecosystems are constructed to provide services such as stormwater retention and urban temperature reductions. Green roofs with shallow growing media represent stressful conditions for plant survival, thus plants ...
-
(Oxford University Press, 2014-08-21)We examine simulations of isolated galaxies to analyse the effects of localized feedback on the formation and evolution of molecular clouds. Feedback contributes to turbulence and the destruction of clouds, leading to a ...
-
(Oxford University Press, 2014-06)Observations (e.g. Phillips, Heckman et al., Martin) have revealed cold gas with large velocity dispersions (≈300 km s−1) within the hot outflows of ultraluminous infrared galaxies (ULIRGs). This gas ...
-
(Oxford University Press, 2014-09-21)The X-ray spectra of the narrow-line Seyfert 1 galaxy, 1H 0707–495, obtained with XMM–Newton, from time periods of varying X-ray luminosity are analysed in the context of understanding the changes to the X-ray ...
-
(Oxford University Press, 2014-06)We present an analysis of the role of feedback in shaping the neutral hydrogen (H I) content of simulated disc galaxies. For our analysis, we have used two realizations of two separate Milky Way-like (∼L★) discs – ...
-
(Oxford University Press, 2014-10-11)We present an analysis of the 2011 photometric observations of TW Hya by the MOST satellite; this is the fourth continuous series of this type. The large-scale light variations are dominated by a strong, quasi-periodic ...
-
(Oxford University Press, 2014-01)The aim of this paper is to quantify the amplitude of the predicted plateau in [α/Fe] ratios associated with the most metal-poor stars of a galaxy. We assume that the initial mass function (IMF) in galaxies is steeper ...
-
(Oxford University Press, 2014-06)We have used the MOST (Microvariability and Oscillations of STars) microsatellite to obtain four weeks of contiguous high-precision broad-band visual photometry of the O7.5III(n)((f)) star ξ Persei in 2011 November . ...
-
(Oxford University Press, 2014-09-11)We present 3–50 keV NuSTAR observations of the active galactic nuclei Mrk 335 in a very low flux state. The spectrum is dominated by very strong features at the energies of the iron line at 5–7 keV and Compton ...
-
The main sequence and the fundamental metallicity relation in MaGICC Galaxies: evolution and scatter (Oxford University Press, 2014-08-01)Using cosmological galaxy simulations from the MaGICC project, we study the evolution of the stellar masses, star formation rates and gas-phase abundances of star-forming galaxies. We derive the stellar masses and star ...
-
(Oxford University Press, 2014-10-01)Using cosmological galaxy formation simulations from the MaGICC (Making Galaxies in a Cosmological Context) project, spanning stellar mass from ∼107 to 3 × 1010 M☉, we trace the ...
-
Chemodynamics of a simulated disc galaxy: initial mass functions and Type Ia supernova progenitors (Oxford University Press, 2014-11-11)We trace the formation and advection of several elements within a cosmological adaptive mesh refinement simulation of an L★ galaxy. We use nine realizations of the same initial conditions with different stellar ...
-
(Oxford University Press, 2014-01-10)We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) cosmological hydrodynamic simulation at z = 0 to study the distribution and environmental dependence of neutral hydrogen (H I) gas in the outskirts ...
-
(Oxford University Press, 2014-01-13)The recent detection of X-ray reverberation lags, especially in the Fe Kα line region, around active galactic nuclei (AGN) has opened up the possibility of studying the time-resolved response (reflection) of hard ...
-
(IOP Publishing, 2014-04)The ζ Aurigae system 31 Cygni (K4 Ib + B4 V) was observed by the FUSE satellite during total eclipse and at three phases during chromospheric eclipse. We present the coadded, calibrated spectra and atlases with line ...
-
(IOP Publishing, 2014-05-20)Spectra for two-dimensional (2D) stars in the 1.5D approximation are created from synthetic spectra of one-dimensional (1D) non-local thermodynamic equilibrium (NLTE) spherical model atmospheres produced by the PHOENIX ...
