Detection of Giant Pulses in pulsar PSR J1752+2359
A. A. Ershov, A. D. Kuzmin
We report the detection of Giant Pulses (GPs) in the pulsar PSR J1752+2359. About one pulse in 270 has a peak flux density more than 40 times the peak flux density of an average pu…
Momentum-resolved spectral functions of SrVO calculated by LDA+DMFT
I. A. Nekrasov, K. Held, G. Keller +6
LDA+DMFT, the merger of density functional theory in the local density approximation and dynamical mean-field theory, has been mostly employed to calculate k-integrated spectra acc…
On the spectra of nonsymmetric Laplacian matrices
Rafig Agaev, Pavel Chebotarev
A Laplacian matrix is a square real matrix with nonpositive off-diagonal entries and zero row sums. As a matrix associated with a weighted directed graph, it generalizes the Laplac…
Local anisotropy and giant enhancement of local electromagnetic fields in fractal aggregates of metal nanoparticles
Sergei V. Karpov, Valeriy S. Gerasimov, Ivan L. Isaev +1
We have shown within the quasistatic approximation that the giant fluctuations of local electromagnetic field in random fractal aggregates of silver nanospheres are strongly correl…
The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation
J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13
We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…
Single-ion anisotropy in the gadolinium pyrochlores studied by an electron paramagnetic resonance
V. N. Glazkov, M. E. Zhitomirsky, A. I. Smirnov +4
The electron paramagnetic resonance is used to measure the single-ion anisotropy of Gd3+ ions in the pyrochlore structure of (Y{1-x}Gdx)2Ti2O7. A rather strong easy-plane type anis…
