X-ray detection of a nova in the fireball phase
Ole König, Jörn Wilms, Riccardo Arcodia +17
Novae are caused by runaway thermonuclear burning in the hydrogen-rich envelopes of accreting white dwarfs, which results in the envelope to expand rapidly and to eject most of its…
A NuSTAR and Swift View of the Hard State of MAXI J1813-095
Jiachen Jiang, Douglas J. K. Buisson, Thomas Dauser +9
We present an analysis of the NuSTAR and Swift spectra of the black hole candidate MAXI J1813-095 in a failed-transition outburst in 2018. The NuSTAR observations show evidence of…
The NICER "Reverberation Machine": A Systematic Study of Time Lags in Black Hole X-Ray Binaries
Jingyi Wang, Erin Kara, Matteo Lucchini +12
We perform the first systematic search of all NICER archival observations of black hole (and candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags…
XMM-Newton Observations of the Narrow-Line Seyfert 1 Galaxy IRAS 132243809 : X-ray Spectral Analysis II
Jiachen Jiang, Thomas Dauser, Andrew C. Fabian +4
Previously, we modelled the X-ray spectra of the narrow-line Seyfert 1 galaxy IRAS 132243809 using a disc reflection model with a fixed electron density of cm.…
High-density disc reflection spectroscopy of low-mass active galactic nuclei
L. Mallick, A. C. Fabian, J. A. García +13
The standard alpha-disc model predicts an anti-correlation between the density of the inner accretion disc and the black hole mass times square of the accretion rate, as seen in hi…
The X-ray Disk/Wind Degeneracy in AGN
M. L. Parker, G. A. Matzeu, J. H. Matthews +4
Relativistic Fe K emission lines from accretion disks and from disk winds encode key information about black holes, and their accretion and feedback mechanisms. We show that these…
