Invitation to VERSIM x GEM Journal Club
Hi all,
January is almost over, which means it’s time for the second Journal Club of 2026! We are excited to have Raahima Khatun-E-Zannat from the University of Colorado Denver presenting her most recent paper on whistler-mode wave propagation.
An introduction from the speaker and the Zoom link are provided
below, and more details of the club can be found here:
https://versim.matfyz.cz/index_jc.html
We hope to see lots of you there!
Best wishes,
Rachel, Mirek, Jodie, Harriet, Yang and Suhail
Date and time: 4th February @ 9am PST / 12pm EST / 5pm UTC
/ 6pm CET

Title: Propagation of whistler mode waves in Earth’s inner
magnetosphere in the presence of field aligned irregularities and
geomagnetic curvature
Khatun-E-Zannat et al, Frontiers, 2025
https://doi.org/10.3389/fspas.2025.1649760
Introduction from the Speaker:
As part of my Ph.D. work, I recently published a paper
investigating whistler-mode wave propagation in cold,
inhomogeneous magnetospheric plasma using coupled full-wave FDTD
and ray-tracing models. In this presentation, I’ll place the
results in the context of the physical motivation, the advantages
and limitations of each modeling approach, and how combining
full-wave and ray-based perspectives helps interpret observations
and improve global understanding of ducted whistler propagation.

URSI GASS 2026 Commission H Sessions: Abstract Deadline
February 9
The triennial URSI General Assembly and Scientific Symposium (URSI
GASS) will be held August 15-22, 2026, in Krakow, Poland. The
abstract submission deadline has been extended to February 9,
2026. Details on the conference can be found at
https://www.ursi-gass2026.pl/.
Also, don’t forget URSI's Young Scientist award program: a limited
number of awards are available to assist young scientists from
both developed and developing countries to attend this meeting.
More details here: https://www.ursi-gass2026.pl/youngscientist
Below you will find a brief overview of the sessions led by
Commission H; the complete list of sessions and their descriptions
are available here: https://www.ursi-gass2026.pl/guidelins
