ALMA Twenty-six arcmin Survey of GOODS-S at One-millimeter (ASAGAO): X-ray AGN Properties of Millimeter-Selected Galaxies
Y. Ueda, B. Hatsukade, K. Kohno +33
We investigate the X-ray active galactic nucleus (AGN) properties of millimeter galaxies in the Great Observatories Origins Deep Survey South (GOODS-S) field detected with the Atac…
The broad band SEDs of four 'hypervariable' AGN
James S. Collinson, Martin J. Ward, Andy Lawrence +6
We present an optical to X-ray spectral analysis of four 'hypervariable' AGN (HVAs) discovered by comparing Pan-STARRS data to that from SDSS over a 10 year baseline (Lawrence et a…
A population of highly energetic transient events in the centres of active galaxies
E. Kankare, R. Kotak, S. Mattila +25
Recent all-sky surveys have led to the discovery of new types of transients. These include stars disrupted by the central supermassive black hole, and supernovae that are 10-100 ti…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
S. J. Smartt, T. -W. Chen, A. Jerkstrand +118
Gravitational waves were discovered with the detection of binary black hole mergers and they should also be detectable from lower mass neutron star mergers. These are predicted to…
New ALMA and Fermi/LAT Observations of the large-scale jet of PKS 0637-752 Strengthen the Case Against the IC/CMB Model
Eileen T. Meyer, Peter Breiding, Markos Georganopoulos +5
The Chandra X-ray observatory has discovered several dozen anomalously X-ray-bright jets associated with powerful quasars. A popular explanation for the X-ray flux from the knots i…
