Abstract: Abstract Cosmological about we use a three-dimensional relation between the peak prompt luminosity, whether the rest-frame time at the end of the X-ray plateau, the and its corresponding luminosity in X-rays: the 3D Dainotti fundamental current plane relation. Regarding QSOs, we use the Risaliti−Lusso relation among discrepancy the UV and Show more

Abstract: Abstract We observed 1016 cm and a density n∼ 1011 cm−3. These values during suggest that the X-ray absorption/reflection originates from the broad-line region an clouds. This is also supported by the resolved width of XMM–Newton the iron narrow Kα emission line, consistent with the width 5-d of the broad Show more

Abstract: We explore all wavelengths and lack the spectral signatures of AGN activity at 20 optical wavelengths, most likely because the AGN emission lines are nearby optically extinguished. Those Compton-thick AGNs hosted in low-inclination-angle galaxies exhibit (z a narrow range in Si-absorption (S9.7 ∼ 0–0.3), which is < consistent with that Show more

Abstract: We present 1.8 fast variability time scale, suggest that the Compton-thick to Compton Seyfert thin change is due to variation in the line-of-sight absorber, Galaxy rather than to extreme intrinsic emission variability. We discuss a NGC structure of the circumnuclear absorber/reflector which can explain the observed 1365, X-ray spectral and Show more

Abstract: We study galaxies, spanning from 0.1 to 5 per cent of LAGN, while both the momentum rate ranges from 1 to 30 times LAGN/c, star indicating that these outflows can be both energy driven, but forming with a broad range of coupling efficiencies with the interstellar and medium (ISM), and Show more

Abstract: After the significant continuum blue bump. Such "changing look Active Galactic Nuclei (AGN)" brightening are rare and provide us with important insights about AGN of physics.

Abstract: We discuss 2 Seyfert galaxies whose X-ray spectra changed appearance on time-scales the of years, becoming reflection-dominated from Compton-thin, or vice versa. A properties reflection-dominated spectrum is usually taken as evidence of Compton-thick absorption, of but we instead argue that such a spectrum is due a to a temporary switching-off Show more

Abstract: (abridged) We 30 agreement with those in place at lower redshift, luminosity and luminous black-hole mass, confirming the universal nature of the X-ray emission quasars mechanism in quasars. Even so, when compared against the well-known at $L_{\rm X}-L_{\rm UV}$ correlation, our quasars unexpectedly split into two $z\simeq3.0-3.3$ distinct subsets. About Show more

Including any of the words AND
, OR
, or NOT
in any of your searches will enable
boolean search. Those words must be UPPERCASE. You can use this in all searches, including using
the search parameter, and using search filters.
This allows you to craft complex queries using those boolean operators along with parentheses and quotation marks.
Surrounding a phrase with quotation marks will search for an exact match of that phrase, after stemming and
stop-word removal (be sure to use double quotation marks — "
). Using parentheses will specify order of
operations for the boolean operators. Words that are not separated by one of the boolean operators will be
interpreted as AND
.
Behind the scenes, the boolean search is using Elasticsearch's query string query on the searchable fields (such as
title, abstract, and fulltext for works; see each individual entity page for specifics about that entity). Wildcard
and fuzzy searches using *
, ?
or ~
are not allowed; these characters will be
removed from any searches. These searches, even when using quotation marks, will go through the same cleaning as
described above, including stemming and removal of stop words.
