Multi-wavelength campaign on NGC7469 II. Column densities and variability in the X-ray spectrum
U. Peretz, E. Behar, G. A. Kriss +16
We investigate the ionic column density variability of the ionized outflows associated with NGC7469, to estimate their location and power. This could allow a better understan…
Active Galactic Nuclei: what's in a name?
P. Padovani, D. M. Alexander, R. J. Assef +8
Active Galactic Nuclei (AGN) are energetic astrophysical sources powered by accretion onto supermassive black holes in galaxies, and present unique observational signatures that co…
Chasing obscuration in type-I AGN: discovery of an eclipsing clumpy wind at the outer broad-line region of NGC 3783
M. Mehdipour, J. S. Kaastra, G. A. Kriss +21
In 2016 we carried out a Swift monitoring program to track the X-ray hardness variability of eight type-I AGN over a year. The purpose of this monitoring was to find intense obscur…
The very faint hard state of the persistent neutron star X-ray binary SLX 1737-282 near the Galactic centre
M. Armas Padilla, G. Ponti, B. De Marco +2
We report on a detailed study of the spectral and temporal properties of the neutron star low mass X-ray binary SLX 1737-282, which is located only ~1degr away from Sgr A. The syst…
