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

(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 ﻿

(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 ...
• #### β-YbAlB4: A Critical Nodal Metal ﻿

(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 ﻿

(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 ﻿

(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 ...
