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.

(American Astronomical Society, 2020-08-14)We present Spitzer 4.5 μm observations of the transit of TOI-700 d, a habitable-zone Earth-sized planet in a multiplanet system transiting a nearby M-dwarf star (TIC 150428135, 2MASS J06282325–6534456). TOI-700 d has a ...
We report the discovery of GJ 1252 b, a planet with a radius of 1.193 ± 0.074 R⊕ and an orbital period of 0.52 days around an M3-type star (0.381 ± 0.019 M⊙, 0.391 ± 0.020 R⊙) located 20.385 ± 0.019 pc away. We use TESS ...
Satellite galaxies in the Illustris-1 simulation: anisotropic locations around relatively isolated hosts (Oxford University Press (OUP), 2019-10-11)We investigate the locations of satellite galaxies in the z = 0 redshift slice of the hydrodynamical Illustris-1 simulation. As expected from previous work, the satellites are distributed anisotropically in the plane of ...
(Nature Research, 2020-03-16)As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen atoms penetrate the heliosphere, and through charge-exchange with the supersonic solar wind, create a population of hot pick-up ions (PUIs). ...
Major scientific challenges and opportunities in understanding magnetic reconnection and related explosive phenomena throughout the universe (2019-05-01)This is a group white paper of 100 authors (each with explicit permission via email) from 51 institutions on the topic of magnetic reconnection which is relevant to 6 thematic areas. Grand challenges and research opportunities ...
(2019-09-01)The Sun blows out the solar wind which propagates into the interplanetary medium and forms the heliosphere about 100 AU across. The solar activity causes various types of time-dependent phenomena in the solar wind from ...
(IOP PUBLISHING LTD, 2017-09-10)We present arcsecond-resolution data in the radio, IR, optical, and X-ray for 4C+19.44 (=PKS 1354+195), the longest and straightest quasar jet with deep X-ray observations. We report results from radio images with half to ...
The Event Horizon Telescope (EHT) is a very long baseline interferometry (VLBI) array that comprises millimeter- and submillimeter-wavelength telescopes separated by distances comparable to the diameter of the Earth. At a ...
We present the calibration and reduction of Event Horizon Telescope (EHT) 1.3 mm radio wavelength observations of the supermassive black hole candidate at the center of the radio galaxy M87 and the quasar 3C 279, taken ...
