Southampton 1 The Disc-Jet connection in LINERS: (and Seyferts..) AMI and X-ray monitoring of M81* Ian M c Hardy, University of Southampton Guy Pooley, MRAO
Southampton 2 Do LINERS show same strong radio/X-ray correlation as hard state X-ray Binaries?
Southampton 3 Previous observations: LINER NGC7213 Bell et al, 2011 S ~ MJD-50000
Southampton 4 NGC7213 (Bell et al)
Southampton 5 M81 X-ray and 15GHz lightcurves Swift keV (Richards, Readhead)
Southampton 6 M81 X-ray and 15GHz Cross-correlation
Southampton 7 M81 X-ray and 15GHz lightcurves
Southampton 8 M81 X-ray and 15GHz F R ~F X 0.7 From Falcke et al 2004 cf Merloni et al 2003 observed Mass-scaling following Falcke jet model
Southampton 9 Disc-Jet Connection in `radio quiet’ AGN: Seyferts Jones et al, 2011 Peak flux ~0.5mJy in A-array NGC4051: VLA A and B array 8GHz observations
Southampton 10 NGC4051 VLA A array observations
Southampton 11 NGC4051 Radio vs. X-ray - all arrays No strong evidence for large amplitude radio variability
Southampton 12 Seyfert NGC5548 – brighter in radio than NGC4051 Wrobel no parallel X-ray observations
Southampton Disc-Jet connection in Seyferts 13 AMI 15GHz map of NGC5548 Core easily distinguished
Southampton 14 Conclusion AMI has an excellent capability for monitoring the radio cores in LINERS and `radio-quiet’ AGN. Strong radio/X-ray correlation seen in LINER M81* greatly strengthening the link to hard state XRBs. Radio/X-ray link is unknown in Seyferts (radio quiet AGN) but could easily be studied with AMI.
