Fast jet proper motion discovered in a blazar at z = 4.72
Yingkang Zhang, Tao An, Sandor Frey
High-resolution observations of high-redshift () radio quasars offer a unique insight into jet kinematics at early cosmological epochs, as well as constraints on cosmological…
Coronal properties of black hole X-ray binaries in the hard state as seen by NuSTAR and Swift
Zhen Yan, Fu-guo Xie, Wenda Zhang
In this work, we measure two important phenomenological parameters of corona (and hot accretion flow) in black hole X-ray binaries: the photon index and the electron temperatur…
New candidate radio supernova remnants detected in the GLEAM survey over ,
Natasha Hurley-Walker, Miroslav D. Filipovic, Bryan M. Gaensler +18
We have detected 27 new supernova remnants (SNRs) using a new data release of the GLEAM survey from the Murchison Widefield Array (MWA) telescope, including the lowest surface-brig…
Candidate radio supernova remnants observed by the GLEAM survey over and
Natasha Hurley-Walker, Bryan M. Gaensler, Denis A. Leahy +18
We examined the latest data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey covering , $180^\circ < l < 240^\…
Radiative Properties of Magnetically-Arrested Disks
Fu-Guo Xie, Andrzej A. Zdziarski
Magnetically-arrested disks (MADs) appear when accretion flows are supplied with a sufficient amount of magnetic flux. In this work, we use results of magnetohydrodynamic simulatio…
Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017
F. D'Ammando, C. M. Raiteri, M. Villata +94
We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…
