Correction to: X-Ray Properties of TDEs
Komossa, S.; Jonker, P. G.; Auchettl, K. +1 more
Observational astronomy of tidal disruption events (TDEs) began with the detection of X-ray flares from quiescent galaxies during the ROSAT all-sky survey of 1990-1991. The flares complied with theoretical expectations, having high peak luminosities (Lx up to ≥4 ×1044 erg/s), a thermal spectrum with k T ∼few ×105 K…

Imaging Plasma Density Structures in the Soft X-Rays Generated by Solar Wind Charge Exchange with Neutrals
Holmström, M.; Read, A. M.; Wing, S. +32 more
Both heliophysics and planetary physics seek to understand the complex nature of the solar wind's interaction with solar system obstacles like Earth's magnetosphere, the ionospheres of Venus and Mars, and comets. Studies with this objective are frequently conducted with the help of single or multipoint in situ electromagnetic field and particle ob…
Towards a Unified View of Inhomogeneous Stellar Winds in Isolated Supergiant Stars and Supergiant High Mass X-Ray Binaries
Fürst, Felix; Kretschmar, Peter; Wilms, Jörn +13 more
Massive stars, at least ∼10 times more massive than the Sun, have two key properties that make them the main drivers of evolution of star clusters, galaxies, and the Universe as a whole. On the one hand, the outer layers of massive stars are so hot that they produce most of the ionizing ultraviolet radiation of galaxies; in fact, the first massive…
X-Ray Observations of Powerful AGN Outflows. Implications for Feedback
Pounds, Ken
Highly ionised winds with velocities ∼0.1-0.2 c were first detected in X-ray spectra of non-BAL AGN a decade ago. Subsequent observations and archival searches have shown such winds to be a common feature of luminous AGN, increasing the belief that powerful ionised winds have a wider importance in galaxy feedback models. Paradoxically, for the bes…
