Abstract:
The SWIFT integral field spectrograph is an adaptive optics assisted I and z-band IFS designed an built by a dedicated instrument team at the University of Oxford. In this thesis I describe my contribution to the construction, commissioning and characterisation of SWIFT as part of the SWIFT team. I also describe two observational projects subsequently undertaken with SWIFT. Firstly a kine- matic study of the ring galaxy Arp 147. This is a typical ring galaxy and companion system, thought to have been created during a collision between the companion galaxy and a normal disk which was subsequently disrupted to form the ring shape seen today. SWIFT was used to obtain spatially resolved kinematics over the ring galaxy thereby probing the conditions under which the collision occurred. Integrated spectra are also used to establish some physical properties associated with the system, leading to a robust understanding of the timescales involved in the interaction. Next SWIFT was used to observe a small sample of redshift desert (z ~ 1) galaxies. These objects were chosen from the DEEP2 sample in order to probe a range of different dominant kinematics, that is galaxies which are rotation-dominated, galaxies which are velocity dispersion- dominated and some objects displaying a mixture between the two. Here I analyse two objects from this sample. The Eagle galaxy is a turbulent and highly star-forming galaxy at a redshift of z = 0.7686. The Eagle exhibits a morphology and uneven kinematics indicating a possible major merger. The Diamond Ring galaxy is a galaxy at a redshift of z = 1.1592. The Diamond Ring also displays disrupted kinematics, with a knotty morphology. It has a typical star formation rate for its mass.
