Identifying the subtle signatures of feedback from distant AGN using ALMA observations and the EAGLE hydrodynamical simulations
J. Scholtz, D. M. Alexander, C. M. Harrison +10
We present sensitive 870m continuum measurements from our ALMA programmes of 114 X-ray selected AGN in the CDF-S and COSMOS fields. We use these observations in combination with…
Deep ALMA photometry of distant X-ray AGN: improvements in star formation rate constraints, and AGN identification
F. Stanley, C. M. Harrison, D. M. Alexander +5
We present the star formation rates (SFRs) of a sample of 109 galaxies with X-ray selected active galactic nuclei (AGN) with moderate to high X-ray luminosities (L(2-8keV)= 10^42-1…
The NuSTAR Extragalactic Survey: Average broad-band X-ray spectral properties of the NuSTAR detected AGN
A. Del Moro, D. M. Alexander, J. A. Aird +18
We present a study of the average X-ray spectral properties of the sources detected by the NuSTAR extragalactic survey, comprising observations of the E-CDFS, EGS and COSMOS fields…
The NuSTAR Serendipitous Survey: Hunting for The Most Extreme Obscured AGN at >10 keV
G. B. Lansbury, D. M. Alexander, J. Aird +27
We identify sources with extremely hard X-ray spectra (i.e., with photon indices of Gamma<0.6 in the 13 sq. deg. NuSTAR serendipitous survey, to search for the most highly obscured…
Hard X-ray selected AGNs in low-mass galaxies from the NuSTAR serendipitous survey
C. -T. J. Chen, W. N. Brandt, A. E. Reines +14
We present a sample of 10 low-mass active galactic nuclei (AGNs) selected from the 40-month NuSTAR serendipitous survey. The sample is selected to have robust NuSTAR detections at…
A tidal disruption event in the nearby ultra-luminous infrared galaxy F01004-2237
C. Tadhunter, R. Spence, M. Rose +2
Tidal disruption events (TDEs), in which stars are gravitationally disrupted as they pass close to the supermassive black holes in the centres of galaxies, are potentially importan…
