3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2623-2654, November 2025.Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

XMM-Newton Observations of the Radio-Loud Broad Absorption Line Quasar FBQS J131213.5+231958 [PDF]
, 2010 We present XMM-Newton observations of the broad absorption line (BAL) quasar FBQS J131213.5+231958. The X-ray spectrum of the source can be well described by an absorbed power-law model in which the absorber is either ionized or only partially covers the

Comprehensive Connection among the Quasars with Different Types of Outflow Absorption Lines
The Astrophysical JournalIt is commonly accepted that outflows from the central regions of quasars play a substantial role in regulating the global properties of the host galaxy. These outflows are typically detected through blueshifted absorption lines.

The location and kinematics of the emission line regions in Active Galactic Nuclei [PDF]
, 2008 This thesis contains the results from a study of the optical emission lines of various samples of active galactic nuclei (AGN). We have used three separate techniques to determine the precise kinematics and the relative location of the emission line ...

Fading Light, Fierce Winds: JWST Snapshot of a Sub-Eddington Quasar at Cosmic Dawn
The Astrophysical Journal LettersThe majority of most luminous quasars during the epoch of reionization accrete near or above the Eddington limit, marking the vigorous growth of primitive supermassive black holes (SMBHs).

Thomson Thick X-ray Absorption in a Broad Absorption Line Quasar, PG 0946+301
, 2015 We present a deep ASCA observation of a broad absorption line quasar (BALQSO) PG 0946+301. The source was clearly detected in one of the gas imaging spectrometers, but not in any other detector.
