Reflection Spectra of the Black Hole Binary Candidate MAXI J1535-571 in the Hard State Observed by NuSTAR
Yanjun Xu, Fiona A. Harrison, Javier A. Garcia +9
We report on a NuSTAR observation of the recently discovered bright black hole candidate MAXI J1535-571. NuSTAR observed the source on MJD 58003 (five days after the outburst was r…
Using principal component analysis to understand the variability of PDS 456
M. L. Parker, J. N. Reeves, G. A. Matzeu +2
We present a spectral-variability analysis of the low-redshift quasar PDS 456 using principal component analysis. In the XMM-Newton data, we find a strong peak in the first princip…
A CO Detection in a Brightest Cluster Galaxy
A. N. Vantyghem, B. R. McNamara, A. C. Edge +7
We present ALMA Cycle 4 observations of CO(1-0), CO(3-2), and CO(3-2) line emission in the brightest cluster galaxy of RXJ0821+0752. This is one of the first detections of $…
The close environments of accreting massive black holes are shaped by radiative feedback
Claudio Ricci, Benny Trakhtenbrot, Michael J. Koss +13
The large majority of the accreting supermassive black holes in the Universe are obscured by large columns of gas and dust. The location and evolution of this obscuring material ha…
Ultra-massive black hole feedback in compact galaxies
W. Ishibashi, A. C. Fabian
Recent observations confirm the existence of ultra-massive black holes (UMBH) in the nuclei of compact galaxies, with physical properties similar to NGC 1277. The nature of these o…
Close entrainment of massive molecular gas flows by radio bubbles in the central galaxy of Abell 1795
H. R. Russell, B. R. McNamara, A. C. Fabian +8
We present new ALMA observations tracing the morphology and velocity structure of the molecular gas in the central galaxy of the cluster Abell 1795. The molecular gas lies in two f…
