Modelling the spectral energy distribution and polarisation of blazars
(North-West University (South Africa), 2019)The optical emission from most blazars is dominated by the polarised synchrotron radiation of relativistic electrons in the jet. However, the thermal radiation from the accretion disc and host galaxy also contributes towards ... -
Optical variability modelling of newly identified blazars and blazar candidates behind Magellanic clouds
(Sissa Medialab, 2019)We present results of a variability study in the optical band of 44 newly identified blazar candidates behind the Magellanic Clouds. Our sample contains 27 flat spectrum radio quasars (FSRQs) and 17 BL Lacertae objects (BL ... -
Progress in multi-wavelength and multi-messenger observations of blazars and theoretical challenges
(MDPI, 2019)This review provides an overview of recent advances in multi-wavelength and multi-messenger observations of blazars, the current status of theoretical models for blazar emission, and prospects for future facilities. The ... -
Search for Lorentz invariance breaking with a likelihood fit of the PKS 2155-304 flare data taken on MJD 53944
(Elsevier, 2011)Several models of Quantum Gravity predict Lorentz Symmetry breaking at energy scales approaching the Planck scale (∼1019 GeV). With present photon data from the observations of distant astrophysical sources, it is possible ...
