The UMIST database for astrochemistry 2012
D. McElroy, C. Walsh, A. J. Markwick +3
We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are new…
Late Spectral Evolution of the Ejecta and Reverse Shock in SN1987A
Claes Fransson, Josefin Larsson, Jason Spyromilio +10
We present observations with VLT and HST of the broad emission lines from the inner ejecta and reverse shock of SN 1987A from 1999 until 2012 (days 4381 -- 9100 after explosion). W…
Realizing a High Magnetic Moment in Gd/Cr/FeCo: The Role of the Rare Earth
C. Ward, G. Scheunert, W. R. Hendren +3
The search for materials or systems exhibiting a high magnetic saturation has been of longstanding importance. It has been suggested that increased saturation could be achieved by…
Spectropolarimetry of the Type Ia SN 2007sr Two Months After Maximum Light
P. Zelaya, J. R. Quinn, D. Baade +6
We present late time spectropolarimetric observations of SN 2007sr, obtained with the VLT telescope at ESO Paranal Observatory when the object was 63 days after maximum light. The…
The VLT-FLAMES Tarantula Survey X: Evidence for a bimodal distribution of rotational velocities for the single early B-type stars
P. L. Dufton, N. Langer, P. R. Dunstall +12
Aims: Projected rotational velocities (\vsini) have been estimated for 334 targets in the VLT-FLAMES Tarantula survey that do not manifest significant radial velocity variations an…
Homological Localisation of Model Categories
David Barnes, Constanze Roitzheim
One of the most useful methods for studying the stable homotopy category is localising at some spectrum E. For an arbitrary stable model category we introduce a candidate for the E…
Selectable linear or quadratic coupling in an optomechanical system
André Xuereb, Mauro Paternostro
There has been much interest recently in the analysis of optomechanical systems incorporating dielectric nano- or microspheres inside a cavity field. We analyse here the situation…
Stellar Surface Magneto-Convection as a Source of Astrophysical Noise. I. Multi-component Parameterisation of Absorption Line Profiles
H. M. Cegla, S. Shelyag, C. A. Watson +1
We outline our techniques to characterise photospheric granulation as an astrophysical noise source. A four component parameterisation of granulation is developed that can be used…
Confidence Statements for Ordering Quantiles
Carlos A. de B. Pereira, Cassio P. de Campos, Adriano Polpo
This work proposes Quor, a simple yet effective nonparametric method to compare independent samples with respect to corresponding quantiles of their populations. The method is sole…
The morphology of the ejecta in Supernova 1987A: a study over time and wavelength
Josefin Larsson, Claes Fransson, Karina Kjaer +9
We present a study of the morphology of the ejecta in Supernova 1987A based on images and spectra from the HST as well as integral field spectroscopy from VLT/SINFONI. The HST obse…
A no-go result on the purification of quantum states
C. Di Franco, M. Paternostro
The information encoded in a quantum system is generally spoiled by the influences of its environment, leading to a transition from pure to mixed states. Reducing the mixedness of…
Phase-space behavior and conditional dynamics of an optomechanical system
S. Groeblacher, S. Gigan, M. Paternostro
We characterize the local properties of an optomechanical system comprising the movable mirror of a resonator and its intracavity field, mutually coupled via radiation-pressure. Ou…
WASP-77 Ab: A transiting hot Jupiter planet in a wide binary system
P. F. L. Maxted, D. R. Anderson, A. Collier Cameron +16
We report the discovery of a transiting planet with an orbital period of 1.36d orbiting the brighter component of the visual binary star BD -07 436. The host star, WASP-77A, is a m…
Testing genuine multipartite nonlocality in phase space
Seung-Woo Lee, Mauro Paternostro, Jinhyoung Lee +1
We demonstrate genuine three-mode nonlocality based on phase space formalism. A Svetlichny-type Bell inequality is formulated in terms of the -parameterized quasiprobability fun…
Period and period change measurements for 143 SuperWASP eclipsing binary candidates near the short-period limit and discovery of a doubly eclipsing quadruple system
M. E. Lohr, A. J. Norton, U. C. Kolb +3
Building on previous work, a new search of the SuperWASP archive was carried out to identify eclipsing binary systems near the short-period limit. 143 candidate objects were detect…
On Achievable Schemes of Interference Alignment with Double-Layered Symbol Extensions in Interference Channel
Haichuan Zhou, Tharm Ratnarajah
This paper looks into the -user interference channel. Interference Alignment is much likely to be applied with double-layered symbol extensions, either for constant channels in…
Close-Form Design of Antenna-Constrained Multi-Cell Multi-User Downlink Interference Alignment
Haichuan Zhou, Tharm Ratnarajah
This paper investigates the downlink channels in multi-cell multi-user interfering networks. The goal is to propose close-form designs to obtain degrees of freedom (DoF) in high SN…
On Achievable Schemes of Interference Alignment in Constant Channels via Finite Amplify-and-Forward Relays
Haichuan Zhou, Tharm Ratnarajah
This paper elaborates on the achievable schemes of interference alignment in constant channels via finite amplify-and-forward (AF) relays. Consider sources communicating with $…
Simulation of relativistically colliding laser-generated electron flows
Xiaohu Yang, Mark E. Dieckmann, Gianluca Sarri +1
The plasma dynamics resulting from the simultaneous impact, of two equal, ultra-intense laser pulses, in two spatially separated spots, onto a dense target is studied via particle-…
Magnetic instability in a dilute circular rarefaction wave
Mark Eric Dieckmann, Gianluca Sarri, Marco Borghesi
The generation of a magnetic field in a circular rarefaction wave is examined in form of a 2D particle-in-cell (PIC) simulation. Electrons with a temperature of 32 keV are uniforml…
