Properties of the Extremely Energetic GRB 221009A from Konus-WIND and SRG/ART-XC Observations

The Astrophysical Journal Letters, 2023
We report on Konus-WIND (KW) and Mikhail Pavlinsky Astronomical Roentgen Telescope – X-ray Concentrator (ART-XC) observations and analysis of a nearby GRB 221009A, the brightest γ -ray burst (GRB) detected by KW for >28 yr of observations.

Molecular theory of elastic constants of liquid crystals. III. Application to smectic phases with tilted orientational order

, 2001
Using the density functional formalism we derive expression for the distortion free energy for systems with continuous broken symmetry and use it to derive expression for the elastic constants of smectic phases in which director is tilted with respect to

Proton beam velocity distributions in an interplanetary coronal mass ejection [PDF]

Annales Geophysicae, 2009
The plasma and magnetic-field instruments on the Helios 2 spacecraft, which was on 3 April 1979 located at 0.68 AU, detected an interplanetary coronal mass ejection (ICME) that revealed itself by the typical signature of magnetic field rotation.

Excited states of a dilute Bose-Einstein condensate in a harmonic trap

, 1997
The low-lying hydrodynamic normal modes of a dilute Bose-Einstein gas in an isotropic harmonic trap determine the corresponding Bogoliubov amplitudes. In the Thomas-Fermi limit, these modes have large low-temperature occupation numbers, and they permit ...

A study of sheared turbulence/shock interaction: velocity fluctuations and enstrophy behaviour [PDF]

, 2012
Direct Numerical Simulations of the idealized interaction of a normal shock wave with several turbulent shear flows are conducted. We analyse the behaviours of velocity and vorticity fluctuations and compare them to what happens in the isotropic ...

Superconducting state in the metastable binary bismuthide Rh3Bi14 single crystals

, 2012
We report detailed magnetic, transport and thermodynamic properties of metastable Rh3Bi14 single crystals in superconducting and normal state. We show that Rh3Bi14 is nearly isotropic, weak to intermediately coupled BCS superconductor, whereas the ...

Reversible and irreversible evolution of a condensed bosonic gas

, 2000
We have formulated a kinetic theory for a condensed atomic gas in a trap, i.e., a generalized Gross-Pitaevskii equation, as well as a quantum-Boltzmann equation for the normal and anomalous fluctuations [R. Walser et al., Phys. Rev.

Exact Solution for the Critical State in Thin Superconductor Strips with Field Dependent or Anisotropic Pinning

, 2000
An exact analytical solution is given for the critical state problem in long thin superconductor strips in a perpendicular magnetic field, when the critical current density j_c(B) depends on the local induction B according to a simple three-parameter ...
