Personal profile

Overview

Klaas Wiersema is a Dutch astrophysicist, specialised in the observational study of transient sources, in particular sources that emit time-variable polarised light. He has published many papers in refereed journals on topics ranging from gravitational wave sources to orbiting satellites, and has been active in building, commissioning and calibrating several astronomical instruments and observatories. Before coming to the University of Hertfordshire, Klaas worked at the University of Lancaster, University of Warwick, University of Leicester and the University of Amsterdam. 

Research interests

  • Classification and characterisation of astrophysical transient sources
  • Polarimetry as probe of non-thermal emission processes in transient sources
  • The electromagnetic counterparts of gravitational wave and neutrino sources (i.e. multi-messenger astronomy)
  • Using spectroscopy of transients to probe high-redshift galaxy properties and cosmology
  • Polarimetry as a quantitative tool in Space Domain Awareness (SDA)
  • Bubbles blown by the jets and accretion disks of X-ray binaries
  • Polarimetric properties of potentially hazardous asteroids (PHAs)
