DESCRIPTION:The Arcminute Microkelvin Imager - Large Array has been instru
 mental in the study of radio transients. In this talk I will give an overv
 iew of the current extragalactic transients monitoring program which is ru
 nning on AMI-LA. To demonstrate the power of AMI-LA in improving our shock
  physics in extragalactic transients I will go through two examples of eve
 nts where AMI-LA has been instrumental. Starting with the most relativisti
 c systems: GRBs have been observed by AMI-LA from as early as 2012 with th
 e ALARRM rapid follow up system. GRB 221009A\, also known as the brightest
  of all time\, has demonstrated the unparalleled temporal coverage achieva
 ble with AMI-LA from a few hours to over 100 days post burst. AMI-LA has a
 lso enabled us to draw conclusions that wouldn’t be possible with other 
 facilities such as the jetted tidal disruption event AT2022cmc that was fi
 rst reported in 2022. Due to the high cadence light curve with AMI-LA\, we
  were able to prove for the first time\, in a model independent manner tha
 t the radio emission originated from a highly relativistic outflow. Such a
  result has been vital in terms of our understand of tidal disruption even
 ts and can now infer the presence of off-axis jets such as AT2018hyz.
