1 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

2 Southampton 2 Do LINERS show same strong radio/X-ray correlation as hard state X-ray Binaries?

3 Southampton 3 Previous observations: LINER NGC7213 Bell et al, 2011 S ~   MJD-50000

4 Southampton 4 NGC7213 (Bell et al)

5 Southampton 5 M81 X-ray and 15GHz lightcurves Swift keV (Richards, Readhead)

6 Southampton 6 M81 X-ray and 15GHz Cross-correlation

7 Southampton 7 M81 X-ray and 15GHz lightcurves

8 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

9 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

10 Southampton 10 NGC4051 VLA A array observations

11 Southampton 11 NGC4051 Radio vs. X-ray - all arrays No strong evidence for large amplitude radio variability

12 Southampton 12 Seyfert NGC5548 – brighter in radio than NGC4051 Wrobel no parallel X-ray observations

13 Southampton Disc-Jet connection in Seyferts 13 AMI 15GHz map of NGC5548 Core easily distinguished

14 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.
