  • Water vapour in the atmosphere of a transiting extrasolar planet 

    Tinetti, Giovanna; Vidal-Madjar, A.; Liang, Mao-Chang; Beaulieu, Jean-Philippe; Yung, Yuk; Carey, Sean; Barber, Robert J.; Tennyson, Jonathan; Ribas, Ignasi; Allard, Nicole; Ballester, G.; Sing, David K.; Selsis, Frank (Nature Publishing Group, 2007)
    Water is predicted to be among the most abundant (if not the most abundant) molecular species after hydrogen in the atmospheres of close-in extrasolar giant planets ('hot Jupiters'). Several attempts have been made to ...
  • Wave propagation in complex coordinates 

    Horsley, SAR; King, CG; Philbin, TG (IOP Publishing, 2016-04-01)
    We give an interpretation for the use of complex spatial coordinates in electromagnetism, in terms of a family of closely related inhomogeneous media. Using this understanding we find that the phenomenon of reflection can ...
  • Waveguide arrays as plasmonic metamaterials: transmission below cutoff 

    Hibbins, Alastair P.; Lockyear, Matthew J.; Hooper, Ian R.; Sambles, J. Roy (American Physical Society, 2006)
    Since the work of Ebbesen et al. [Nature (London) 391, 667 (1998)], there has been immense interest in the optical properties of subwavelength holes in metal layers. While the enhanced transmission observed is generally ...
  • What can simulated molecular clouds tell us about real molecular clouds? 

    Duarte-Cabral, A; Dobbs, CL (Oxford University Press, 2016-03-03)
    © 2016 The Authors.We study the properties of giant molecular clouds (GMCs) from a smoothed particle hydrodynamics simulation of a portion of a spiral galaxy, modelled at high resolution, with robust representations of the ...
  • White dwarf dynamical interactions and fast optical transients 

    Garcia-Berro, E; Badenes, C; Aznar-Siguan, G; Loren-Aguilar, P (Oxford University Press (OUP) / Royal Astronomical Society, 2017-04-03)
    Recent advances in time-domain astronomy have uncovered a new class of optical transients with timescales shorter than typical supernovae and a wide range of peak luminosities. Several subtypes have been identi ed within ...
  • Wolf-Rayet spin at low metallicity and its implication for Black Hole formation channels 

    Vink, J; Harries, TJ (EDP Sciences, 2017-04-12)
    Context. The spin of Wolf-Rayet (WR) stars at low metallicity (Z) is most relevant for our understanding of gravitational wave sources such as GW150914, as well as the incidence of long-duration gamma-ray bursts (GRBs). ...
  • X-ray diffraction from bone employing annular and semi-annular beams. 

    Dicken, AJ; Evans, JP; Rogers, KD; Stone, N; Greenwood, C; Godber, SX; Prokopiou, D; Clement, JG; Lyburn, ID; Martin, RM; Zioupos, P (IOP Publishing, 2015-08-07)
    There is a compelling need for accurate, low cost diagnostics to identify osteo-tissues that are associated with a high risk of fracture within an individual. To satisfy this requirement the quantification of bone ...
  • The X-ray source population of the globular cluster M15: Chandra high-resolution imaging 

    Hannikainen, DC; Charles, PA; van Zyl, L; Kong, AKH; Homer, L; Hakala, P; Naylor, T; Davies, MB (Oxford University Press (OUP) / Royal Astronomical Society, 2005-02-01)
    The globular cluster M15 was observed on three occasions with the High Resolution Camera on-board Chandra in 2001 in order to investigate the X-ray source population in the cluster centre. After subtraction of the two ...
  • Young Stellar Objects in the Gould Belt 

    Dunham, MM; Allen, LE; Evans, NJ; Broekhoven-Fiene, H; Cieza, LA; Di Francesco, J; Gutermuth, Robert A.; Harvey, P.M.; Hatchell, Jennifer; Heiderman, A; Huard, TL; Johnstone, D; Kirk, JM; Matthews, BC; Miller, JF; Peterson, DE; Young, KE (American Astronomical Society, 2015-09-01)
    We present the full catalog of Young Stellar Objects (YSOs) identified in the 18 molecular clouds surveyed by the Spitzer Space Telescope “cores to disks” (c2d) and “Gould Belt” (GB) Legacy surveys. Using standard techniques ...
  • Zero-energy states in graphene quantum dots and rings 

    Downing, C.A.; Stone, D.A.; Portnoi, M.E. (2011)
    We present exact analytical zero-energy solutions for a class of smooth-decaying potentials, showing that the full confinement of charge carriers in electrostatic potentials in graphene quantum dots and rings is indeed ...
  • Zigzag-Shaped Superlattices on the Basis of Graphene Nanoribbons: Structure and Electronic Properties 

    Saroka, VA; Batrakov, KG (Springer Verlag, 2016-09-08)
    The paper focuses on superlattices consisting of two coplanar fragments of one-layer graphene nanoribbons that have different width and are connected at an angle. Classification of such superlattices was carried out; their ...
  • α-Tocopherols modify the membrane dipole potential leading to modulation of ligand binding by P-glycoprotein 

    Davis, Sterenn; Davis, Benjamin M.; Richens, Joanna L.; Vere, Kelly-Ann; Petrov, Peter G.; Winlove, C. Peter; O'Shea, Paul (American Society for Biochemistry and Molecular Biology, 2015-08)
    α-Tocopherol (vitamin E) has attracted considerable attention as a potential protective or palliative agent. In vitro, its free radical-scavenging antioxidant action has been widely demonstrated. In vivo, however, vitamin ...
