Luke Majury –

Biography: I am Luke, a PhD student researching multi-wavelength observations of solar flares under Dr. Ryan Milligan. I have recently completed my first year of PhD study following the completion of an integrated master’s degree in astrophysics at QUB. Before starting an integrated master’s degree, I developed an interest in astronomy whilst undertaking a GCSE in the subject during my spare time under the tutelage of my secondary school physics teacher. My research currently revolves around comparisons of hydrogen Lyman-alpha and hard X-ray emissions during solar flares.

Synopsis/Abstract: Solar flares are among the most powerful events in our solar system. They occur due to the release of magnetic energy in the uppermost layer of the solar atmosphere. This process accelerates particles to high energies, with these energetic particles dissipating their energy via Coulomb collisions, resulting in a burst of electromagnetic radiation which we observe as a flare. Solar flares have been observed as early as 1859 during the Carrington event, since then great advances have been made in our understanding of flares via both observational and theoretical work. As we approach the peak of solar cycle 25 flares will become more frequent, allowing for abundant observations to be made with state-of-the-art observatories such as Solar Orbiter, Solar-C and the Advanced Space-Based Solar Observatory.

Title: Fast! Slow? Bright or Faint‽: exploring the diversity of supernovae

With the advent of large-scale robotic sky surveys, the number of supernovae we discover has ’exploded’. In this talk I will discuss what supernovae are, some of the history of their discovery and their incredible diversity.

I will also discuss the discovery, follow-up, and periodic signals of SN 2022jli – the most exciting supernova of the decade? (although I am biased).

Bio: 

Thomas is a final year astrophysics PhD student at Queen’s University Belfast where he obtained an MSci in Physics with Astrophysics in 2021. His research focuses on observation and modelling of supernovae discovered by the ATLAS all-sky survey and spectroscopic observations using the ESO New Technology Telescope.  

Venue: Larmor Lecture Theatre, Physics building, Queen’s University Belfast, 7.30 p.m.

Admission free, including light refreshments. All welcome.

Synopsis: Space weather is a very complex field, involving many different subject areas, that as a community we are still working to grasp. This talk will discuss what some current points of concern are, and the science and missions being directed at them. 

Biography: Elizabeth Butler grew up in Minneapolis, Minnesota, hating physics. She wanted to write novels about dragons instead. Something shifted in high school – enough that she graduated from Northern Michigan University with a double bachelors in physics and writing.

After taking a gap year to drive mowers and utility carts around 32 miles of hiking trails while composing poetry in her head, she was accepted as a graduate student by the Astrophysical and Planetary Sciences Department of the University of Colorado in Boulder. There, she fell in love with planetariums, solar physics, and the developing field of space weather, and later used all three to become a Fellow in the National Science Foundation’s Graduate Research program.

After weathering two wildfire evacuation notices, a mass shooting, and a global pandemic, she graduated with her PhD in 2022, defending a dissertation that was two thirds solar flare physics and one third human subjects work on bridging the space weather research and forecasting communities.

She then accepted the opportunity to move across the pond to work at Queen’s Astrophysics Research Centre, where she has only received one of the seven visits threatened by friends and family. “
