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, 2022-01-01)V471 Tau is a post-common-envelope binary consisting of an eclipsing DA white dwarf and a K-type main-sequence star in the Hyades star cluster. We analyzed publicly available photometry and spectroscopy of V471 Tau to ...
A 2+1+1 quadruple star system containing the most eccentric, low-mass, short-period, eclipsing binary known We present an analysis of a newly discovered 2+1+1 quadruple system with TESS containing an unresolved eclipsing binary (EB) as part of TIC 121088960 and a close neighbor TIC 121088959. The EB consists of two very low-mass ...
(2021)The Radio Ammonia Mid-Plane Survey (RAMPS) has detected 537 filamentary molecular clumps and characterized their properties. I investigated the kinematic properties of a subsample of 115 molecular filaments to test theories ...
(2021)The Radio Ammonia Mid-Plane Survey (RAMPS) has detected 2,680 molecular clumps and characterized their properties. This data set provides the clump-averaged gas properties for this sample.
(2021)The Radio Ammonia Mid-Plane Survey (RAMPS) has detected 707 H2O masers and characterized their properties. This data set provides the maser properties for this sample.
(2021)The Radio Ammonia Mid-Plane Survey (RAMPS) has detected 2,680 molecular clumps and characterized their properties. I utilized the derived clump properties to test the gravitational stability of a subsample of 314 molecular ...
Multiwavelength variability and correlation studies of Mrk 421 during historically low X-ray and γ-ray activity in 2015–2016 (Oxford University Press (OUP), 2020-12-03)We report a characterization of the multi-band flux variability and correlations of the nearby (z=0.031) blazar Markarian 421 (Mrk 421) using data from Metsähovi, Swift, Fermi-LAT, MAGIC, FACT and other collaborations and ...
Observation of a sudden cessation of a very-high-energy gamma-ray flare in PKS 1510-089 with H.E.S.S. and MAGIC in May 2016 The flat spectrum radio quasar (FSRQ) PKS 1510-089 is known for its complex multiwavelength behavior, and is one of only a few FSRQs detected at very high energy (VHE, E >100 GeV) 𝛾-rays. VHE 𝛾-ray observations with ...
(2020-10-02)The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new and clean gravitational test of the ...
VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020 (2021)CONTEXT: QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength campaign allowed us to trace the evolution ...
