Detection of a High-Temperature Blackbody Hump in Black Hole Spectra. The strongly redshifted annihilation line

Lev Titarchuk, Elena Seifina

We discovered a so called high-temperature blackbody (HBB) component, found in the 15 -- 40 keV range, in the broad-band X-ray energy spectra of black hole (BH) candidate sources.…

Spectral index-mass accretion rate correlation and evaluation of black hole masses in AGNs 3C~454.3 and M87

Lev Titarchuk, Elena Seifina, Alexandre Chekhtma +1

We present the discovery of correlations between the X-ray spectral (photon) index and mass accretion rate observed in active galactic nuclei (AGNs) 3C~454.3 and M87. We analyzed s…

Symmetry breaking in competing single-well linear-nonlinear potentials

Dmitry A. Zezyulin, Mikhail E. Lebedev, Georgy L. Alfimov +1

The combination of linear and nonlinear potentials, both shaped as a single well, enables competition between the confinement and expulsion induced by the former and latter potenti…

Trends in Russian research output indexed in Scopus and Web of Science

Henk F. Moed, Valentina Markusova, Mark Akoev

Trends are analysed in the annual number of documents published by Russian institutions and indexed in Scopus and Web of Science, giving special attention to the time period starti…

Stereotype approximation property for the group algebra of measures

S. S. Akbarov

The stereotype approximation property is formally a stronger condition than the classical approximation property, and because of that the question which spaces possess the stereoty…

On higher order Codazzi tensors on complete Riemannian manifolds

I. G. Shandra, S. E. Stepanov

We prove several Liouville-type non-existence theorems for higher order Codazzi tensors and classical Codazzi tensors on complete and compact Riemannian manifolds, in particular. T…

Localized modes in the Gross-Pitaevskii equation with a parabolic trapping potential and a nonlinear lattice pseudopotential

G. L. Alfimov, L. A. Gegel, M. E. Lebedev +2

We study localized modes (LMs) of the one-dimensional Gross-Pitaevskii/nonlinear Schrödinger equation with a harmonic-oscillator (parabolic) confining potential, and a periodically…

Is there a need for dark matter in galaxies?

I. K. Rozgacheva, A. A. Agapov

We present arguments indicating that galaxies and their clusters should be considered as open developing systems. Galaxies interact with the intergalactic medium and are not in a v…

Quantization of branched coverings

Alexander Pavlov, Evgenij Troitsky

We identify branched coverings (continuous open surjections p:Y->X of Hausdorff spaces with uniformly bounded number of pre-images) with Hilbert C*-modules C(Y) over C(X) and with…

Quasi-multipliers of Hilbert and Banach C*-bimodules

Alexander Pavlov, Ulrich Pennig, Thomas Schick

Quasi-multipliers for a Hilbert C*-bimodule V were introduced by Brown, Mingo and Shen 1994 as a certain subset of the Banach bidual module V**. We give another (equivalent) defini…

Holomorphic Functions of Exponential Type and Duality for Stein Groups with Algebraic Connected Component of Identity

S. S. Akbarov

We suggest a generalization of Pontryagin duality from the category of commutative Stein groups to the category of (not necessarily commutative) Stein groups with algebraic connect…

Around SuSy 1970

Evgeny Likhtman

This is the talk given at the Symposium "Thirty Years of Supersymmetry", October 13-15, 2000, Theoretical Physics Institute, University of Minnesota. The history of construction of…
