Example of a stable wormhole in general relativity
K. A. Bronnikov, L. N. Lipatova, I. D. Novikov +1
We study a static, spherically symmetric wormhole model whose metric coincides with that of the so-called Ellis wormhole but the material source of gravity consists of a perfect fl…
Narrow-line Seyfert Galaxies. Connection between abundance and the large-scale structure
A. A. Ermash
In this work the correlations between spatial concentrations of active nuclei (NLS and BLS) and concentration of galaxies of full uniform sample were obtained. Methods, developed b…
Analyzing polarization swings in 3C 279
S. Kiehlmann, T. Savolainen, S. G. Jorstad +53
Quasar 3C 279 is known to exhibit episodes of optical polarization angle rotation. We present new, well-sampled optical polarization data for 3C 279 and introduce a method to disti…
Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
Physical conditions in star forming regions around S235
Maria S. Kirsanova, Dmitry S. Wiebe, Andrej M. Sobolev +2
Gas density and temperature in star forming regions around Sh2-235 are derived from ammonia line observations. This information is used to evaluate formation scenarios and to deter…
The TeV blazar Markarian 421 at the highest spatial resolution
M. G. Blasi, R. Lico, M. Giroletti +14
We report the results obtained for the AGN Markarian 421 by model-fitting the data in the visibility plane, studing the proper motion of jet components, the light curve, and the sp…
