Multimarginal Optimal Transport Maps for One-dimensional Repulsive Costs

We study a multimarginal optimal transportation problem in one dimension. For a symmetric, repulsive cost function, we show that, given a minimizing transport plan, its symmetrization is induced by a cyclical map, and that the symmetric optimal plan is uni ...

Evidence for major mergers of galaxies at 2 less than or similar to z < 4 in the VVDS and VUDS surveys

Jean-Paul Richard Kneib

Context. The mass assembly of galaxies can proceed through different physical processes. Here we report on the spectroscopic identification of close physical pairs of galaxies at redshifts 2 less than or similar to z < 4 and discuss the impact of major mer ...

Hubble Space Telescope Grism Spectroscopy Of Extreme Starbursts Across Cosmic Time: The Role Of Dwarf Galaxies In The Star Formation History Of The Universe

Jean-Paul Richard Kneib, Hakim Atek, Patrick Mccarthy

Near infrared slitless spectroscopy with the Wide Field Camera 3, on board the Hubble Space Telescope, offers a unique opportunity to study low-mass galaxy populations at high redshift (z similar to 1-2). While most high-z surveys are biased toward massive ...

Lifting degeneracies in Higgs couplings using single top production in association with a Higgs boson

Andrea Thamm, Ennio Salvioni

Current Higgs data show an ambiguity in the value of the Yukawa couplings to quarks and leptons. Not so much because of still large uncertainties in the measurements but as the result of several almost degenerate minima in the coupling profile likelihood f ...

HERSCHEL-ATLAS: A BINARY HyLIRG PINPOINTING A CLUSTER OF STARBURSTING PROTOELLIPTICALS

Jean-Paul Richard Kneib, Hui Fu, Johan Richard

Panchromatic observations of the best candidate hyperluminous infrared galaxies from the widest Herschel extragalactic imaging survey have led to the discovery of at least four intrinsically luminous z = 2.41 galaxies across an approximate to 100 kpc regio ...

Search for Time-dependent Neutrino Emission from Astrophysical Sources with 3 yr of IceCube Data

Matthias Wolf, Shirit Cohen, Sofia Vallecorsa, Mathieu Ribordy, Xiaoxia Bai

We present the results of a search for neutrino point sources using the IceCube data collected between 2008 April and 2011 May with three partially completed configurations of the detector: the 40-, 59-, and 79-string configurations. The live-time of this ...

Magnetic energy flows during the current quench and termination of disruptions with runaway current plateau formation in JET and implications for ITER

James Paley

The magnetic energy balance and magnetic energy flows for plasma disruptions in which runaway plateau plasmas are formed and terminated at JET has been analysed and compared with that of runaway-free disruptions. The analysis shows that the energy loss pro ...
