Scattering from Dusty Outflows in Hot Dust-Obscured Galaxies with Blue Excess Emission
R. J. Assef, M. Stalevski, F. E. Bauer +15
(Context) Hot Dust-Obscured Galaxies (Hot DOGs) are a population of hyper-luminous quasars heavily obscured by dust and gas. While most have rest UV/optical SEDs dominated by their…
Broadband Spectral Modeling of Blazars: Constraining the Lorentz Factor and Gamma-Ray Emission Site
Ajay Sharma, Aishwarya Sarath, Sakshi Chaudhary +1
We present a comprehensive temporal and spectral analysis of a few blazars using multi-wavelength observations. Rapid flux variations are quantified via the doubling/halving timesc…
Exploring Year-timescale Gamma-ray Quasi-Periodic Oscillations in Blazars: Evidence for Supermassive Binary Black Holes Scenario
Ajay Sharma, Sakshi Chaudhary, Aishwarya Sarath +1
A comprehensive analysis of quasi-periodic oscillations (QPOs) in the gamma-ray emissions of blazars. Utilizing 15 years of Fermi-LAT observations of seven blazars in our sample, w…
Radiation Signatures of Electron Acceleration in the Decelerating Jet of MAXI J1348-630
Aishwarya Sarath, Markus Boettcher
A discrete jet component (blob) ejection and its subsequent deceleration was observed in the 2019/2020 outburst in the low-mass X-ray binary MAXI J1348-630. A first kinematic analy…
