Multiband optical flux density and polarization microvariability study of optically bright blazars
Magdalena Pasierb, Arti Goyal, Michał Ostrowski +21
We present the results of flux density, spectral index, and polarization intra-night monitoring studies of a sample of eight optically bright blazars, carried out by employing seve…
Thermoelectric properties of Half-Metallic FeMnScGa Using First Principle Calculation
Shubham Singh, Saurabh Singh, Nitinkumar Bijewar +1
Here, we have investigated the thermoelectric properties of FeMnScGa alloy by combined use of full potential linearized augmented plane-wave (FP-LAPW) method and Boltzmann transpor…
Investigation of Thermoelectric properties of Magnetic Insulator FeRuTiSi Using First Principle Calculation
Saurabh Singh, Shubham Singh, Nitinkumar Bijewar +1
In this work, we have investigated the electronic structure and thermoelectric properties of quaternary heusler alloy, FeRuTiSi, using first principle DFT tools implemented in WIEN…
Causes of the Diurnal Variation observed in -ray Spectrum using NaI (Tl) Detector
Gauri Datar, Geeta Vichare, C. Selvaraj +2
Present paper studies the -ray spectrum observed using NaI(Tl) scintillation detector over a year. The paper reports the presence of a distinct diurnal pattern in the total numb…
X-shaped Radio Galaxies: Optical Properties, Large-scale Environment and Relationship to Radio Structure
Ravi Joshi, Gopal-Krishna, Xiaolong Yang +9
In order to find clues to the origin of the "winged" or "X-shaped" radio galaxies (XRGs) we investigate here the parent galaxies of a large sample of 106 XRGs for optical-radio axe…
Long term variability and correlation study of the blazar 3C 454.3 in radio, NIR and optical wavebands
A. Sarkar, V. R. Chitnis, A. C. Gupta +11
We performed a long-term optical (B, V, R bands), infra-red (J and K bands) and radio band (15, 22, 37 GHz band) study on the flat spectrum radio quasar, 3C 454.3, using the data c…
