J1234+3901: an extremely metal-deficient compact star-forming dwarf galaxy at redshift 0.133
Y. I. Izotov, T. X. Thuan, N. G. Guseva
We have obtained optical spectroscopy of one of the most metal-poor dwarf star-forming galaxies (SFG) in the local Universe, J1234+3901, with the Large Binocular Telescope (LBT)/Mu…
New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
Superconductivity in SrTiO: dielectric function method for non-parabolic bands
S. N. Klimin, J. Tempere, J. T. Devreese +3
The dielectric function method for superconductivity has been applied to SrTiO accounting for the non-parabolic dispersion of charge carriers in the conduction band and for t…
The host galaxies of luminous type 2 AGN at 0.3-0.4
J. J. Urbano-Mayorgas, M. Villar Martín, F. Buitrago +7
We study the morphological and structural properties of the host galaxies associated with 57 optically-selected luminous type 2 AGN at 0.3-0.4: 16 high-luminosity Seyfert 2…
Inhomogeneous magnon scattering during ultrafast demagnetization
R. Knut, E. K. Delczeg-Czirjak, S. Jana +20
NiFe (Py) and Py alloyed with Cu exhibit intriguing ultrafast demagnetization behavior, where the Ni magnetic moment shows a delayed response relative to the Fe, an…
Testing a reported correlation between arrival directions of ultrahigh-energy cosmic rays and a flux pattern from nearby starburst galaxies using Telescope Array data
Telescope Array Collaboration, R. U. Abbasi, M. Abe +138
The Pierre Auger Collaboration (Auger) recently reported a correlation between the arrival directions of cosmic rays with energies above 39 EeV and the flux pattern of 23 nearby st…
