  • Title: "The Dawn of Gravitational Wave Astronomy with LIGO" (Video)

    Abstract: On September 14, 2015, the two Advanced detectors of the Laser Interferometer Gravitational Wave Observatory (LIGO) detected gravitational waves from a binary black hole system, opening the era of gravitational wave astronomy. The signal, denoted GW150914, swept in frequency from 35Hz to 250Hz, and had a peak gravitational-wave...

  • Title: "Spin and Magnetism in Small Stars" (Video)

    Abstract:  Main sequence stars with masses below approximately 0.35 solar masses (red dwarfs, or M dwarfs) are fully-convective, and are expected to have a different type of dynamo mechanism than solar-type stars. These low-mass stars are the most common type of star in the galaxy, but a lack of observational constraints at ages beyond 1 Gyr has hampered...

  • Title: "Colliding Cosmologies: Cultural Conflicts and the Future of Astronomy on Mauna Kea" (Video)

    Abstract: Clouds of controversy surround the summit of Mauna Kea on the Big Island of Hawai’i. Astronomers know Mauna Kea as home to world-class observational facilities, such as the W.M. Keck Observatory and Subaru telescope, its clear skies and unobstructed views virtually unmatched...

  • Title: “Testing Bell’s Inequality with Astrophysical Observations” (Video)

    Abstract:  Albert Einstein once dubbed quantum entanglement "spooky action at a distance," and the concept remains one of the starkest examples of how quantum theory differs from our usual intutions about space, time, and matter. Physicists have tested Bell’s inequality experimentally for over four decades, and have always found...

  • Professor Devin Walker recently spoke with Dartmouth News about his research into dark matter. You can read the full interview at Dartmouth News.

  • My interests center around the theoretical and computational study of plasma physics. The current foci of my research are the kinetic physics of magnetic reconnection, and its broader relation to plasma physics and nonlinear dynamics; Through changing the topology of magnetic field lines, magnetic reconnection is one of the most efficient energy conversion and transport processes in the laboratory, space, and astrophysical plasmas.

  • Nizar Ezroura and Parker Gardner presented a successful talk on their work with Assistant Professor Devin Walker at the MIT Summer Undergraduate Cosmology Workshop on August 2nd.  In the picture, they are standing with Alan Guth, the eminent MIT professor.  Their talk was entitled "The Limits of Dark Matter from Electroweak Symmetry Breaking."  

    Nizar Ezroura and Parker Gardner computed the amount of dark matter generated in the early universe for a common set of highly motivated dark...

  • Congratulations to Mary Hudson for her recent recognition as the 2017 AGU John Adam Fleming Medalist. The Medal is given to honor “original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and/or related sciences.” 

  • McKinley Brumback and Christina Gilligan received recognition at the annual Dartmouth Graduate Poster Session. Five students were recognized, including Brumback and Gilligan. Read more about it in the Dartmouth News.

  • Computational Stellar Evolution focuses on the development of a two-dimensional computer models which predict the evolution of stars. These models will be used to study the effects of magnetic fields and rotation on the evolution of low mass stars. One application of these models is to study the lithium abundance in metal-poor stars to determine the primordial abundance of lithium, which is a key constraint on big bang nucleosynthesis.
