Mrk421 long term monitoring

Mrk421 long-term monitoring

  • ARGO-YBJ cumulative light curve (>TeV) compared with Swift and Rossi/RXTE data.

  • Good correlation between TeV/X-ray data.

  • No other continuous observation at TeV energies

ARGO-YBJ coll., ApJ 734 (2011) 110

RXTE/ASM 2-12 keV

Swift/BAT 15-50 keV

ARGO-YBJ TeV

Mrk501

A strong X-ray flare in 1997 followed by a long “quiet” period

New strong X-ray flare 14 years later: Oct 2011

Flare associated to a strong TeV emission detected by ARGO-YBJ
