Spectra of HB 21 supernova remnant: Evidence of spectra flattening at the low frequencies
D. Borka, V. Borka Jovanović, D. Urošević
We use observations of the continuum radio emission at 1420, 820, 408, 34.5 and 22 MHz to estimate the mean brightness temperatures of the HB 21 supernova remnant (SNR) at five fre…
The brightness temperatures of the main Galactic radio-loops at 22 MHz
D. Urošević, V. Borka Jovanović
The average brightness temperatures and surface brightnesses at 22 MHz are derived for the four main Galactic radio-continuum loops (Loops I, II, III and IV, hereafter radio-loops)…
Temperature, brightness and spectral index of the Cygnus radio loop
V. Borka Jovanović, D. Urošević
The estimated brightness of the Cygnus loop supernova remnant (SNR) at 2720, 1420, 820, 408 and 34.5 MHz are presented. The observations of the continuum radio emission are used to…
High-energy plasmon spectroscopy of freestanding multilayer graphene
V. Borka Jovanović, I. Radović, D. Borka +1
We present several applications of the layered electron gas model to electron energy loss spectroscopy of free-standing films consisting of graphene layers in a scanning transm…
