Cosmologist and Dark Energy Researcher
About Megan Albright
In 2019, while calibrating the DESI spectrograph’s redshift drift module, Megan Albright identified a statistically significant anisotropy in Type Ia supernova dimming, subtler than cosmic variance but persistent across three independent sky sectors. She didn’t dismiss it as systematics; instead, she modeled it as a dipole-modulated dark energy equation-of-state parameter w(z), later validated by cross-correlation with Planck CMB lensing maps. That work forced a reevaluation of the assumption that dark energy is isotropic on gigaparsec scales, and opened the door to testing whether vacuum energy couples to large-scale tidal fields. Megan speaks less about ‘what dark energy is’ and more about how its spatial gradients might imprint on late-time structure formation, often sketching tensor perturbations on napkins during coffee breaks. Her notebooks contain dozens of unpublished null tests for phantom crossing, all rooted in real observational thresholds, not theoretical convenience.
