    • X-Ray and Radio Observations of the Magnetar SGR J1935+2154 during Its 2014, 2015, and 2016 Outbursts 

      Younes, George; Kouveliotou, Chryssa; Jaodand, Amruta; Baring, Matthew G.; van der Horst, Alexander J.; Harding, Alice K.; Hessels, Jason W.T.; Gehrels, Neil; Gill, Ramandeep; Huppenkothen, Daniela; Granot, Jonathan; Göğüş Ersin; Lin, Lin (2017)
      We analyzed broadband X-ray and radio data of the magnetar SGR J1935+2154 taken in the aftermath of its 2014, 2015, and 2016 outbursts. The source soft X-ray spectrum <10 keV is well described with a blackbody+power-law ...
    • X-ray laser implementation by means of a strong source of high-spin metastable atoms 

      Helman, J.S.; Rau, C.; Bunge, C.F. (1983)
      High-spin metastable atomic beams of high density and extremely small divergence can be produced by electron capture during grazing-angle scattering of ion beams at ferromagnetic surfaces. This can be used to generate a ...
    • XENON1T dark matter data analysis: Signal reconstruction, calibration, and event selection 

      XENON Collaboration (2019)
      The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above 6  GeV/c2 scattering ...
    • β-YbAlB4: A Critical Nodal Metal 

      Ramires, Aline; Coleman, Piers; Nevidomskyy, Andriy H.; Tsvelik, A. M. (2012-10)
      We propose a model for the intrinsic quantum criticality of β-YbAlB4, in which a vortex in momentum space gives rise to a new type of Fermi surface singularity. The unquenched angular momentum of the |J=7/2,mJ=±5/2⟩ Yb 4f ...
    • ΛΛ Correlation Function in Au+Au Collisions at √sNN=200  GeV 

      STAR Collaboration; Butterworth, J.; Eppley, G.; Geurts, F.; Llope, W.J.; Roberts, J.B.; Xin, K.; Yepes, P. (2015)
      We present ΛΛ correlation measurements in heavy-ion collisions for Au+Au collisions at √sNN=200  GeV using the STAR experiment at the Relativistic Heavy-Ion Collider. The Lednický-Lyuboshitz analytical model has been used ...
    • ρ0 photoproduction in AuAu collisions at √sNN=62.4 GeV measured with the STAR detector 

      STAR Collaboration; Eppley, G.; Geurts, F.; Liu, J.; Llope, W.J.; McDonald, D.; Roberts, J.B.; Yepes, P. (2012)
      Vector mesons may be photoproduced in relativistic heavy-ion collisions when a virtual photon emitted by one nucleus scatters from the other nucleus, emerging as a vector meson. The STAR Collaboration has previously presented ...
