Short time-scale X-ray spectral variability in the Seyfert 1 galaxy NGC 3783
D. Costanzo, M. Dadina, C. Vignali +9
We report on the X-ray time resolved spectral analysis of XMM-Newton observations of NGC 3783. The main goal is to detect transient features in the Fe K line complex, in order to s…
Menura: a code for simulating the interaction between a turbulent solar wind and solar system bodies
Etienne Behar, Shahab Fatemi, Pierre Henri +1
Despite the close relationship between planetary science and plasma physics, few advanced numerical tools allow to bridge the two topics. The code Menura proposes a breakthrough to…
Whistler instability driven by the sunward electron deficit in the solar wind
Laura Berčič, Daniel Verscharen, Christopher J. Owen +18
Solar wind electrons play an important role in the energy balance of the solar wind acceleration by carrying energy into interplanetary space in the form of electron heat flux. The…
Transient obscuration event captured in NGC 3227. I. Continuum model for the broadband spectral energy distribution
M. Mehdipour, G. A. Kriss, J. S. Kaastra +21
From Swift monitoring of a sample of active galactic nuclei (AGN) we found a transient X-ray obscuration event in Seyfert-1 galaxy NGC 3227, and thus triggered our joint XMM-Newton…
The Inner Accretion Flow in the Resurgent Seyfert-1.2 AGN Mrk 817
J. M. Miller, Z. Zoghbi, M. T. Reynolds +10
Accretion disks and coronae around massive black holes have been studied extensively, and they are known to be coupled. Over a period of 30 years, however, the X-ray (coronal) flux…
