    • A hard gamma-ray flare from 3C 279 in 2013 December 

      Paliya, Vaidehi S.; Diltz, Chris; Böttcher, Markus; Stalin, C.S.; Buckley, David (IOP, 2016)
      The blazar 3C 279 exhibited twin γ-ray flares of similar intensity in 2013 December and 2014 April. In this work, we present a detailed multi-wavelength analysis of the 2013 December flaring event. Multi-frequency observations ...
    • Leptonic and hadronic modeling of Fermi-LAT hard spectrum quasars and predictions for high-energy polarization 

      Paliya, Vaidehi S.; Böttcher, Markus; Zhang, Haocheng; Ajello, M.; Domínguez, A. (IOP Publishing, 2018)
      We present the results of a study of the time-averaged spectral energy distributions (SEDs) of eight flat spectrum radio quasars (FSRQs) present in the second catalog of high energy sources detected beyond 50 GeV by the ...
    • The violent hard X-ray variability of Mrk 421 observed by NuSTAR in 2013 April 

      Paliya, Vaidehi S.; Böttcher, Markus; Diltz, Chris; Stalin, C.S.; Sahayanathan, S. (American Astronomical Society, 2015)
      The well-studied blazar Markarian 421 (Mrk 421, z = 0.031) was the subject of an intensive multi-wavelength campaign when it flared in 2013 April. The recorded X-ray and very high-energy (E > 100 GeV) γ-ray fluxes are the ...
