Supersoft, luminous X-ray sources in galactic nuclei
Andrea Sacchi, Guido Risaliti, Giovanni Miniutti
Tidal disruption events (TDEs) are usually discovered at X-ray or optical wavelengths through their transient nature. A characteristic spectral feature of X-ray detected TDEs is a…
Supermassive Black Hole Winds in X-rays: SUBWAYS. II. HST UV spectroscopy of winds at intermediate redshifts
M. Mehdipour, G. A. Kriss, M. Brusa +35
We present a UV spectroscopic study of ionized outflows in 21 active galactic nuclei (AGN), observed with the HST. The targets of the SUBWAYS sample were selected with the aim to p…
Supermassive Black Hole Winds in X-rays -- SUBWAYS. I. Ultra-fast outflows in QSOs beyond the local Universe
G. A. Matzeu, M. Brusa, G. Lanzuisi +48
We present a new X-ray spectroscopic study of luminous () active galactic nuclei (AGNs) at intermed…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Repeating tidal disruptions in GSN 069: Long-term evolution and constraints on quasi-periodic eruptions' models
G. Miniutti, M. Giustini, R. Arcodia +4
GSN 069 is the first galactic nucleus where quasi-periodic eruptions (QPEs) have been identified. These are high-amplitude, soft X-ray bursts recurring every ~9 hr, lasting ~1 hr,…
A disk instability model for the quasi-periodic eruptions of GSN 069
Xin Pan, Shuang-Liang Li, Xinwu Cao +2
GSN 069 is a recently discovered QPE (Quasi-periodic eruptions) source recurring about every 9 hours. The mechanism for the QPEs of GSN 069 is still unclear so far. In this work, a…
