Re-awakening of GRS 1716-249 after 23 yr, observed by Swift/XRT and NuSTAR
(Oxford Univ Press, 2019)
In this work, we present a spectral and temporal analysis of Swift/XRT and NuSTAR
observations of GRS 1716–249 during its recent 2016–2017 outburst. This low-mass X-ray
binary underwent an extraordinary outburst after a ...
Impact of ordered and disordered magnetic fields on multiwavelength emission of blazars
(IOP Publishing, 2020)
We present a detailed analysis of the effects of magnetic field topology on the spectral energy distribution (SED) and spectral variability patterns (SVPs) of blazars. In order to study these effects, we have extended our ...
Cascading constraints from neutrino-emitting blazars: the case of TXS 0506+056
(IOP Publishing, 2019)
We present a procedure to generally constrain the environments of neutrino-producing sites in photomeson production models of jetted active galactic nuclei (AGNs) where any origin of the dominant target photon field can ...
MSP binaries as astrophysical laboratories
(Cambridge Univ Press, 2018)
Follow-up of unidentified Fermi sources has expanded the number of known galactic-field “black widow” and “redback” millisecond pulsar binaries from four to nearly 30. Several systems observed by Chandra, XMM-Newton, Suzaku, ...
X-ray polarimetry with the Polarization Spectroscopic Telescope Array (PolSTAR)
(Elsevier, 2016)
This paper describes the Polarization Spectroscopic Telescope Array (PolSTAR), a mission proposed to NASA’s 2014 Small Explorer (SMEX) announcement of opportunity. PolSTAR measures the linear polarization of 3–50 keV ...
Diagnosing relativistic particle acceleration in AGN jets
(AIP, 2017)
Mildly relativistic, oblique shocks are generally considered to be among the most plausible sites of relativistic particle acceleration and the subsequent production of strongly variable, polarized multi-wavelength emission ...
