The Department of Astronomy guides students at the undergraduate and graduate levels toward the advanced mathematical skills and physical insight they need to understand the nature of the universe from the modern scientific perspective. The department offers three undergraduate concentrations: astronomy, astronomy and physics, and planetary and space sciences. It offers an MA for students interested in careers in scientific applications, scientific computing, and related fields, and a PhD for students interested in research and academic careers in astrophysics and space physics. The department has two outstanding affiliated research centers, the Center for Space Physics and the Institute for Astrophysical Research.

The Andenes specular meteor radar shows meteor-trail diffusion rates increasing on average by ~ 20% at times and locations where a lidar observes noctilucent clouds (NLCs). This high-latitude effect has been attributed to ...
(2011)Terrestrial exoplanets are observationally challenging to detect and characterize. Compared to gas giant exoplanets, terrestrial exoplanets introduce significantly smaller radial velocity signals and transit depths on their ...
Simulations of secondary Farley-Buneman instability driven by a kilometer-scale primary wave: anomalous transport and formation of flat-topped electric fields (AMER GEOPHYSICAL UNION, 2019-01-01)Since the 1950s, high frequency and very high frequency radars near the magnetic equator have frequently detected strong echoes caused ultimately by the Farley‐Buneman instability (FBI) and the gradient drift instability ...
(2018-06-12)This new freshman honors seminar, to be first offered in Spring 2019, uses the development of the concept of energy from the 17th to the 20th century to combine the teaching of both scientific inquiry and intellectual ...
(American Astronomical Society, 2019-01-22)M subdwarfs are low-metallicity M dwarfs that typically inhabit the halo population of the Galaxy. Metallicity controls the opacity of stellar atmospheres; in metal-poor stars, hydrostatic equilibrium is reached at a smaller ...
Multi-wavelength characterization of the blazar S5 0716+714 during an unprecedented outburst phase (EDP SCIENCES S A, 2018-11-09)CONTEXT: The BL Lac object S5 0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC observations were triggered by the ...
Summary of observations of blazars from radio through gamma-ray wavelengths, and their interpretation in terms of relativistic jets of ultra-high-energy particles and magnetic fields, powered by super-massive black holes ...
(EDP Sciences S A, 2017-07-01)CONTEXT: PKS 1510−089 is one of only a few flat spectrum radio quasars detected in the very-high-energy (VHE, > 100 GeV) gamma-ray band. AIMS: We study the broadband spectral and temporal properties of the PKS 1510−089 ...
We report results from a deep polarization imaging of the nearby radio galaxy 3C 84 (NGC 1275). The source was observed with the Global Millimeter VLBI Array (GMVA) at 86 GHz at an ultra-high angular resolution of 50μas ...
