Pairs of mutually annihilating operators
Vitalij M. Bondarenko, Tatiana G. Gerasimova, Vladimir V. Sergeichuk
Pairs (A,B) of mutually annihilating operators AB=BA=0 on a finite dimensional vector space over an algebraically closed field were classified by Gelfand and Ponomarev [Russian Mat…
Bose-Einstein condensation of magnons under incoherent pumping
A. V. Chumak, G. A. Melkov, V. E. Demidov +3
Bose-Einstein condensation in a gas of magnons pumped by an incoherent pumping source is experimentally studied at room temperature. We demonstrate that the condensation can be ach…
On a spherical code in the space of spherical harmonics
Andriy Bondarenko
In this short note we propose a new method for construction new nice arrangement on the sphere using the spaces of spherical harmonic.
Distances and peculiar velocities of spiral galaxies in the 2MFGC and SFI++ samples
Yu. N. Kudrya, V. E. Karachentseva, I. D. Karachentsev +2
We compare infrared Tully-Fisher (TF) distances and peculiar velocities derived for spiral galaxies from the two largest datasets: the 2MASS selected Flat Galaxy Catalog, 2MFGC [19…
Aspect angle for interstellar magnetic field in SN 1006
O. Petruk, G. Dubner, G. Castelletti +6
A number of important processes taking place around strong shocks in supernova remnants (SNRs) depend on the shock obliquity. The measured synchrotron flux is a function of the asp…
Q2237+0305 in X-rays: spectra and variability with XMM-Newton
E. V. Fedorova, V. I. Zhdanov, C. Vignali +1
X-ray observations of gravitationally lensed quasars may allow us to probe the inner structure of the central engine of a quasar. Observations of Q2237+0305 (Einstein Cross) in X-r…
