Gabriel is an Advanced Study Program Postdoctoral Fellow working at the High Altitude Observatory. His interests are strongly rooted in gaining an improved understanding of the structure and dynamics of the solar corona.

Great Grandson of Walter & Annie Maunder Thanks HAO

Annie Maunder's birthday book and her formal portrait displayed together

I just wanted to drop you an email to thank you for the recent bio pages for Walter and Annie S D Maunder presented on the UCAR NCAR website. In particular, I’m pleased to see the Elliot and Fry studio portrait being used for Annie.

Atomic structure calculations of Land ́e g factors of astrophysical interest with direct applications for solar coronal magnetometry

Non-relativistic Land ́e g factor
Thursday, May 6, 2021

We perform a detailed theoretical study of the atomic structure of ions with ns2npm ground configurations and focus on departures from LS coupling which directly affect the Land ́e g factors of magnetic dipole lines between levels of the ground terms.

Congratulations to Gang Lu, elected fellow of the AGU

The High Altitude Observatory is proud to acknowledge Dr. Gang Lu for being among the 2020 class of AGU Fellows, just recently announced. Gang is a Senior Scientist at HAO.

I was born and raised on the Crimean peninsula on the northern coast of the Black Sea (Eastern Europe), an area currently disputed between Russia and Ukraine. In brief, I was born in a politically incorrect place.

Upper atmosphere radiance data assimilation: A feasibility study for GOLD far ultraviolet observations

Graph depicting accuracy of temperature estimates
Tuesday, January 7, 2020

Availability of far ultraviolet observations of Earth’s dayglow by the NASA Global-scale Observations of the Limb and Disk (GOLD) mission presents an unparalleled opportunity for upper atmosphere radiance data assimilation.

Sun-Like Stars Shed Light on Solar Climate Forcing

Seasonally averaged data for the CaII“S-index” and for the average magnitudes of the Strömgrenbplusy filters
Tuesday, January 7, 2020

Recently published, precise stellar photometry of 72 Sun-like stars obtained at the Fairborn Observatory between 1993 and 2017 is used to set limits on the solar forcing of Earth’s atmosphere of ±4.5 W m−2 since 1750.
