Atmospheric and Space Physics / Physique atmosphérique et spatiale (DASP/DPAE)

Oral not-in-competition (Undergraduate Student) / Orale non-compétitive (Étudiant(e) du 1er cycle)

Total Electron Content (TEC) measurements derived from Global Positioning System (GPS) signals have become indispensable for application-driven ionospheric characterization, detection and characterization of “weak ionospheric signals” resulting from seismic and weather activities, underpinning the accuracy of satellite navigation, space weather forecasting, and ionospheric corrections in...

542. JWST/MIRI-MRS Integral-Field Spectroscopy of the Galactic Center and IRS 16 NW

Atmospheric and Space Physics / Physique atmosphérique et spatiale (DASP/DPAE)

Oral not-in-competition (Undergraduate Student) / Orale non-compétitive (Étudiant(e) du 1er cycle)

This study presents a spectroscopic analysis of the central few parsecs around Sgr A* using the Mid-Infrared Instrument in Medium-Resolution Spectroscopy (MIRI-MRS) Integral-Field Spectroscopy (IFS) mode on JWST. Data consist of calibrated three-dimensional spectral cubes spanning the full MRS coverage λ∈[4.9, 27.9] μm at resolving power R∈[1330, 3750]. From these cubes we derive...

660. CHASM: A Bayesian Framework for Predicting Ionospheric Scintillation Over the Canadian Arctic

Atmospheric and Space Physics / Physique atmosphérique et spatiale (DASP/DPAE)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Rapid fluctuations in GPS signal phase and amplitude—known as scintillation—degrade positioning accuracy in high-latitude regions. This work introduces the Canadian High Arctic Scintillation Model (CHASM), a Bayesian inference framework that predicts scintillation probability and intensity over the Canadian Arctic with high spatial and temporal accuracy under both quiet and disturbed...

944. Detection and Analysis of XRD Effects on PIXL XRF Spectra

Atmospheric and Space Physics / Physique atmosphérique et spatiale (DASP/DPAE)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The Planetary Instrument for X-ray Lithochemistry (PIXL) is an instrument on the Mars 2020 rover. It provides high spatial resolution X-ray fluorescence (XRF) spectra of Martian samples. The instrument has a spot size of ~150um and is mounted on the rovers arm, allowing rastering over a ~cm^2 sample. Although it is not a dedicated X-ray diffraction (XRD) instrument, the dual detectors of the...
