My previous postdoctoral fellowship was at Queen's University, Kingston, Ontario, working with Dr. Judith Irwin on the exciting project Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES). During this time, I observed 406 hours worth of data (!) with the Karl. G. Jansky Very Large Array (VLA) in New Mexico, and subsequently worked on this treasury of data with a wonderful group of astronomers from all over the world.
During my family leave, I have continued to work on this project in different capacities, and currently I am involved with the next data release for the C configuration observations (for the first and second data releases, D and B configuration, see the CHANG-ES website and my paper Wiegert et al 2015 (D configuration data release, arXiv link here) as well as Irwin et al. 2019 (B configuration data release) and the exciting news release here).
I am also working on a project (also CHANG-ES related) on tidal disruption events in two galaxies, where we simultaneously observed using both the VLA (radio) and the SWIFT telescope (X-ray) in 2016.
Autumn 2019, I taught the 3rd year astrophysics course PHYS315 at Queens.
Please check out my CV (link at bottom) for full list of publications.
Galaxy formation and evolution, galaxy kinematics, neutral hydrogen content, properties of disk galaxies, 'communication' between the disk and the gaseous halo, including the magnetic fields. Observations (VLA, JCMT, ATCA, OSO) and data reductions (CASA, IRAF, APLpy, python, matlab, etc...). Outreach and teaching! And thus any new astronomy discovery, the history of astronomy, as well as the art of communicating astronomy and science in the exciting manner which it deserves!
I did my graduate studies (PhD) in astrophysics at the University of Manitoba, Canada, supervised by Dr. Jayanne English. My PhD thesis was on the topics of Spiral galaxy HI models, rotation curves and kinematic classifications (the link leads to its online location). Before that, I got my MSc degree in physics at the Göteborg University, Sweden, where I did my thesis work on galaxy evolution (using Hubble Deep Field South) at the Onsala Space Observatory.
