Dr. Adam F. Kowalski joined the National Solar Observatory and the Department of Astrophysical and Planetary Sciences as Assistant Professor. His research interests are solar and stellar astrophysics with a specialization in spectroscopy of optical and ultraviolet emission in stellar flares. Adam uses stateoftheart modeling codes and techniques combined with analysis of data from ground and spacebased observatories to understand how the lower, dense stellar atmosphere is heated in response to the sudden release of magnetic energy during flares. Recently, he has been working on connecting the physical processes in solar flares to much (up to 1000 times!) more energetic flares on red dwarf stars using data from NASA’s Interface Region Imaging Spectrograph and the Cosmic Origins Spectrograph on the Hubble Space Telescope. He will be actively participating in the science plan for studying flares with future data from the Daniel K. Inouye Solar Telescope.

Primary Instructor

Spring 2019 / Spring 2020
Lab course in observation and instrumentation. Handson exercises include obtaining and analyzing multiwavelength data, optical design and instrumentation, and statistical analysis, with emphasis on spectroscopy. A significant number of night time observation sessions are required. Elective for APS majors. Elective for APS minors on space available basis.
ASTR 5550  Observations, Data Analysis and Statistics
Primary Instructor

Spring 2021 / Spring 2022
Introduces multiwavelength observational techniques,their limitations and effects of various noise sources. Describes basic data handling, error analysis, and statistical tests relevant to modeling. Topics include probability distributions, modelfitting algorithms, confidence intervals, correlations, sampling and convolution. Students derive physical measurements and uncertainties with handson analysis of real datasets. Department enforced prerequisite: senior level undergraduate physics or instructor consent will be required.
