Transition Radiation from the Neutrino-Photon Interaction in Matter
Transition Radiation the Neutrino-Photon Interaction Matter
2012/2/23
We show that, because of their effective electromagnetic interaction in matter, transition radiation is emitted whenever neutrinos goes across the boundary between two media with different indices of ...
Spectro-timing analysis of Cygnus X-1 during a fast state transition
X-rays: binaries, X-rays: individual: CygX-1
2011/10/19
We present the analysis of two long, quasi-uninterrupted RXTE observations of Cygnus X-1 that span several days within a 10 d interval. The spectral characteristics during this observation cover the r...
Curvature perturbation spectra from waterfall transition, black hole constraints and non-Gaussianity
waterfall transition black hole constraints non-Gaussianity
2011/10/11
We carried out numerical calculations of a contribution of the waterfall field to the primordial curvature perturbation (on uniform density hypersurfaces) $\zeta$, which is produced during waterfall t...
Surface tension in the cold and dense chiral transition and astrophysical applications
Surface tension old chiral transition astrophysical applications
2011/10/18
The surface tension of cold and dense QCD phase transitions has appeared recently as a key ingredient in different astrophysical scenarios, ranging from core-colapse supernovae explosions to compact s...
The revival of an explosion mechanism of massive stars - the quark hadron phase transition during the early post bounce phase of core collapse supernovae
Core collapse supernovae protoneutron stars general relativity radiation hydrodynamics
2010/11/16
We explore explosions of massive stars, which are triggered via the quark hadron phase transition during the early post bounce phase of core collapse supernovae. The onset of quark matter is favored u...
Phase transition to the state with nonzero average helicity in dense neutron matter
Phase transition nonzero average dense neutron matter
2010/11/16
The possibility of the appearance of the states with a nonzero average helicity in neutron matter is studied in the model with the Skyrme effective interaction. By providing the analysis of the selfco...
Probing the Transition Between the Synchrotron and Inverse-compton Spectral Components of 1ES 1959+650
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
1ES 1959+650 is one of the most remarkable high-peaked BL Lacertae objects (HBL). In 2002, it exhibited a TeV gamma-ray flare without a similar brightening of the synchrotron component at lower energi...
