Writing in The Conversation, Roy Kilgard, research associate professor of astronomy, explains the significance of an exciting new discovery in astronomy. For the first time, astrophysicists have observed merging neutron stars using LIGO (the Laser Interferometer Gravitational-Wave Observatory) and the Virgo interferometer. Kilgard writes: This news may confirm a longstanding theory: that some gamma-ray bursts (GRBs for short), which are among the most energetic, luminous events in the universe, are the result of merging neutron stars. And it is in the crucible of these mergers that most heavy elements may be forged. Researchers can’t produce anything like the temperatures or pressures of…

Four Wesleyan undergraduate students have received grants from NASA's Connecticut Space Grant Consortium. Astronomy major Hannah Fritze '18 was awarded $5,000 for an Undergraduate Research Fellowship Grant titled, “Searching for Intermediate Mass Black Holes in Ultraluminous X-ray Binaries.” This grant will support her research this coming semester on black holes with Roy Kilgard, support astronomer and research associate professor of astronomy. Avi Stein '17, who is majoring in astronomy, was awarded $1,000 for a Student Travel Grant. He will be presenting his research on Venus—conducted with Martha Gilmore, the George I. Seney Professor of Geology, professor of earth and environmental sciences—at…

The Hartford Courant featured the 100th anniversary of Wesleyan's Van Vleck Observatory, which will be celebrated with an exhibit and a series of events this month and next. The "Under Connecticut Skies" exhibit, located in the observatory library, will open May 6 from 10 a.m. to 6 p.m., and will remain open indefinitely during the observatory's public hours. Amrys Williams, visiting assistant professor of history, who has been working on the exhibit since last year, said the Van Vleck Observatory and the astronomy department building are part of the exhibit, telling the story of how astronomers did their work 100 years ago.…

Wesleyan's Van Vleck Observatory is celebrating its centennial this spring, with a series of events and an exhibition beginning in early May. On May 6, the observatory's library will reopen to the public with an exhibition on the history of astronomy at Van Vleck. Developed by a team of faculty, students, and staff, the exhibition will use the observatory's extensive collection of scientific instruments, teaching materials, photographs, drawings, and correspondence to illustrate both the changes in astronomical research and teaching over the past century, and the observatory's consistent mission of conducting instruction and research under the same roof. The exhibition will…

Astronomy magazine has an in-depth feature in its October issue on Wesleyan's astronomical history and the restoration of its century-old, 20-inch refractor telescope, just in time for the Van Vleck Observatory's centennial observation this spring. Telescopes like Wesleyan's 28-foot-long, two-ton refractor had once been cutting edge, and a source of pride for dozens of American universities. But as they "staggered into obsolescence" over the past half century, institutions have had to make tough choices about whether to renovate or retire them. In 2014, Wesleyan hired Chris Ray and Fred Orthlieb of Pennsylvania to give its refractor a second life. The story traces the history…
