Dramatic changes in the observed velocity of the accretion disk wind in MCG-03-58-007 are revealed by XMM-Newton and NuSTAR
V. Braito, J. N. Reeves, G. Matzeu +6
Past X-ray observations of the nearby Seyfert 2 MCG-03-58-007 revealed the presence of a powerful and highly variable disk wind, where two possible phases outflowing with $v_{\rm o…
Possible X-ray Quasi-Periodic Eruptions in a Tidal Disruption Event Candidate
Joheen Chakraborty, Erin Kara, Megan Masterson +3
X-ray Quasi-Periodic Eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high amplitude soft X-ray f…
Multiphase Powerful Outflows Detected in High-z Quasars
George Chartas, Massimo Cappi, Cristian Vignali +7
We present results from a comprehensive study of ultrafast outflows (UFOs) detected in a sample of fourteen quasars, twelve of which are gravitationally lensed, in a redshift range…
On Synthetic Absorption Line Profiles of Thermally Driven Winds from Active Galactic Nuclei
Shalini Ganguly, Daniel Proga, Tim Waters +7
The warm absorbers observed in more than half of all nearby active galactic nuclei (AGN) are tracers of ionized outflows located at parsec scale distances from the central engine.…
Observations of a radio-bright, X-ray obscured GRS 1915+105
S. E. Motta, J. J. E. Kajava, M. Giustini +9
The Galactic black hole transient GRS1915+105 is famous for its markedly variable X-ray and radio behaviour, and for being the archetypal galactic source of relativistic jets. It e…
