Photoionized emission and absorption features in the high-resolution X-ray spectra of NGC 3783
Junjie Mao, M. Mehdipour, J. S. Kaastra +14
Our Swift monitoring program triggered two joint XMM-Newton, NuSTAR and HST observations on 11 and 21 December 2016 targeting NGC 3783, as its soft X-ray continuum was heavily obsc…
What drives the radio slopes in radio quiet quasars?
Ari Laor, Ranieri D. Baldi, Ehud Behar
The origin of the radio emission in Radio Quiet (RQ) quasars is not established yet. Important hints can be provided by the spectral slope, and its relation to other emission prope…
Variable Nature of Magnetically-Driven Ultra-Fast Outflows
Keigo Fukumura, Demosthenes Kazanas, Chris Shrader +3
Among a number of active galactic nuclei (AGNs) that drive ionized outflows in X-rays, a low-redshift (z = 0.184) quasar, PDS 456, is long known to exhibit one of the exemplary ult…
Supernova PTF12glz: a possible shock breakout driven through an aspherical wind
Maayane T. Soumagnac, Eran O. Ofek, Avishay Gal-Yam +21
We present visible-light and ultraviolet (UV) observations of the supernova PTF12glz. The SN was discovered and monitored in near-UV and R bands as part of a joint GALEX and Paloma…
Classifying AGN by X-ray Hardness Variability
Uria Peretz, Ehud Behar
The physics behind the dramatic and unpredictable X-ray variability of Active Galactic Nuclei (AGN) has eluded astronomers since it was discovered. We present an analysis of Swift…
What we learn from the X-ray grating spectra of Nova SMC 2016
M. Orio, J. -U. Ness, A. Dobrotka +17
Nova SMC 2016 has been the most luminous nova known in the direction of the Magellanic Clouds. It turned into a very luminous supersoft X-ray source between day 16 and 28 after the…
