Even a precessing clock is right twice per orbit -- The super-periods of eRO-QPE2 and challenges for quasi-periodic eruption orbital models
R. Arcodia, G. Miniutti, J. Chakraborty +25
We present OC (``observed minus calculated'') timing analysis of the quasi-periodic eruption (QPE) source eRO-QPE2 with a multi-mission X-ray campaign, which includes 32 observe…
Diffuse X-ray Emission in the Sagittarius C Complex
Zhenlin Zhu, Mark R. Morris, Gabriele Ponti +1
The Sagittarius C (Sgr C) complex, located on the western edge of the Central Molecular Zone (CMZ), hosts a mixture of star-forming and non-thermal activity whose X-ray properties…
SRG/eROSITA No. 5: Discovery of quasi-periodic eruptions every ~3.7 days from a galaxy at z>0.1
R. Arcodia, P. Baldini, A. Merloni +17
Quasi-periodic eruptions (QPEs) are repeating soft X-ray bursts from the nuclei of galaxies, tantalizingly proposed to be extreme mass ratio inspirals. Here, we report the discover…
Fragments of harmony amid apparent chaos: a closer look at the X-ray quasi-periodic eruptions of the galaxy RX J1301.9+2747
Margherita Giustini, Giovanni Miniutti, Riccardo Arcodia +17
Quasi-periodic eruptions (QPEs) are an extreme X-ray variability phenomenon associated with low-mass supermassive black holes. First discovered in the nucleus of the galaxy GSN 069…
Ticking away: the long-term X-ray timing and spectral evolution of eRO-QPE2
R. Arcodia, I. Linial, G. Miniutti +11
Quasi-periodic eruptions (QPEs) are repeated X-ray flares from galactic nuclei. Despite some diversity in the recurrence and amplitude of eruptions, their striking regularity has m…
Testing EMRI models for Quasi-Periodic Eruptions with 3.5 years of monitoring eRO-QPE1
Joheen Chakraborty, Riccardo Arcodia, Erin Kara +13
Quasi-Periodic Eruptions (QPEs) are luminous X-ray outbursts recurring on hour timescales, observed from the nuclei of a growing handful of nearby low-mass galaxies. Their physical…
Broad iron L-line and X-ray reverberation in 1H0707-495
A. Zoghbi, A. Fabian, P. Uttley +5
A detailed analysis of a long XMM-Newton observation of the Narrow Line Seyfert 1 galaxy 1H0707-495 is presented, including spectral fitting, spectral variability and timing studie…
Probing variability patterns of the Fe K line complex in bright nearby AGNs
B. De Marco, K. Iwasawa, M. Cappi +5
The unprecedented sensitivity of current X-ray telescopes allows for the first time to address the issue of the Fe K line complex variability patterns in bright, nearby AGNs. We ex…
Suzaku observations of Markarian 335: evidence for a distributed reflector
J. Larsson, G. Miniutti, A. C. Fabian +3
We report on a 151 ks net exposure Suzaku observation of the Narrow Line Seyfert 1 galaxy Mrk 335. The 0.5-40 keV spectrum contains a broad Fe line, a strong soft excess below abou…
