How do I stop these nodes from running

edit

For context, I am working on a simulation for a robot and I am using an external library for pointcloud to laserscan conversion. Everything was originally working fine, but all of a sudden I have these ros2 nodes running which I can't figure out how to kill. I believe they are stopping my TF frames from registering. I have tried using the kill command and trying to find them using "htop", and I have tried finding them in my system monitor, but I can't seem to locate them anywhere to try and shut them down. These are the names of the nodes and the properties:

/vtr/boreas_odometry_feaeexyoeg
/vtr/boreas_odometry_xkzleovjry
/vtr/boreas_odometry_yvjvpzmakr
