FURTHER GENERALISATIONS OF THE KUMMER-SCHWARZ EQUATION: ALGEBRAIC AND SINGULARITY PROPERTIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)The Kummer–Schwarz Equation, 2y'y'''− 3(y'')2 = 0, has a generalisation, (n − 1)y(n−2)y(n) − ny(n−1)2 = 0, which shares many properties with the parent form in terms of symmetry and singularity. All equations of the class ... -
GALACTIC AND EXTRAGALACTIC SUPERNOVA REMNANTS AS SITES OF PARTICLE ACCELERATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Supernova remnants, owing to their strong shock waves, are likely sources of Galactic cosmic rays. Studies of supernova remnants in X-rays and gamma rays provide us with new insights into the acceleration of particles to ... -
GALACTIC CENTER MINISPIRAL: INTERACTION MODES OF NEUTRON STARS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)Streams of gas and dust in the inner parsec of the Galactic center form a distinct feature known as the Minispiral, which has been studied in radio waveband as well as in the infrared wavebands. A large fraction of the ... -
Gamma-rays, Neutrinos and Particle Astronomy as Messengers of the Universe
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Observations of charged cosmic-rays, γ-rays and neutrino are possible thanks to the availability of new detectors coming from technologies typical of experimental particle physics. In conjunction with more traditional ... -
