A Full Characterisation of the Supermassive Black Hole in IRAS 09149-6206
D. J. Walton, W. N. Alston, P. Kosec +11
We present new broadband X-ray observations of the type-I Seyfert galaxy IRAS 09149-6206, taken in 2018 with -, and . The source is highly complex, sho…
Using Multiwavelength Variability to Explore the Connection between X-ray Emission, the Far-Ultraviolet H2 Bump, and Accretion in T Tauri Stars
C. C. Espaillat, C. Robinson, S. Grant +1
The high-energy radiation fields of T Tauri stars (TTS) should affect the surrounding circumstellar disk, having implications for disk transport and heating. Yet, observational evi…
A Low-Flux State in IRAS 00521-7054 seen with NuSTAR and XMM-Newton: Relativistic Reflection and an Ultrafast Outflow
D. J. Walton, E. Nardini, L. C. Gallo +8
We present results from a deep, coordinated -+ observation of the Seyfert 2 galaxy IRAS 00521-7054. The data provide the first detection of this sourc…
Broad Iron Emission from Gravitationally Lensed Quasars Observed by Chandra
D. J. Walton, M. T. Reynolds, J. M. Miller +3
Recent work has demonstrated the potential of gravitationally lensed quasars to extend measurements of black hole spin out to high-redshift with the current generation of X-ray obs…
Are spectral and timing correlations similar in different spectral states in black hole X-ray binaries?
M. Kalamkar, M. T. Reynolds, M. van der Klis +2
We study the outbursts of the black hole X-ray binaries MAXI J1659-152, SWIFT J1753.5--0127 and GX 339-4 with the Swift X-ray Telescope. The bandpass of the X-ray Telescope has acc…
Broad relativistic iron emission line observed in SAX J1808.4-3658
E. M. Cackett, D. Altamirano, A. Patruno +4
During the September-October 2008 outburst of the accreting millisecond pulsar SAX J1808.4-3658, the source was observed by both Suzaku and XMM-Newton approximately 1 day apart. Sp…
