Model predictions for flux vs time(solid lines) compared to observations (symbols).
GW170817, detected on August 17, 2017, was the first multi-messenger astronomical source, seen in gravitational waves and across the whole electromagnetic spectrum. Much of the physics of this source has been understood thanks to the high quality data collected for months after the initial detection. We now know that it was due to the collision between two neutron stars, a class of very massive and compact stars that were in orbit around each other and eventually merged forming a black hole. During the collision material was flung out in all directions. Most of the material was sent in the equatorial direction, where new atoms – such as gold and platinum – were formed through rapid neutron capture. Some material was sent in the polar direction, but exactly how much and with what energy is not known, since our observing geometry is far from the polar axis. For that reason, it had been impossible to ascertain whether a short gamma-ray burst also took place with the star collision.
Short gamma-ray bursts are some of the brightest explosions recorded in present day universe. They are produced when extremely fast outflows are sent in our direction by leftover material that accretes onto a newly formed black hole. Scientists believe they should be caused by a neutron star collision, but direct evidence is not yet available. When we detect  the burst directly, it is so bright that outshines all the signs of the neutron star collision. Groundbreaking research performed by the astrophysics group led by Dr. Lazzati and accepted for publication in Physical Review Letters, however, has shown that the unusual increase of the luminosity of GW170817 over time is a sign that a short GRB did happen right after the merger, albeit along a different direction. The figure displays the model predictions (solid lines) along with the observations (symbols), showing the excellent agreement of the model with the data.

The American Physical Society has recognized OSU Physics for Improving Undergraduate Physics Education.

STARKVILLE, Miss.—A tropical cyclone authority at Mississippi State is a new selection for the American Meteorological Society’s Early Career Leadership Academy.

Assistant professor Kimberly Wood soon will be among nearly three dozen 2018 ECLA members receiving special training in Washington, D.C. She came to the Starkville campus three years ago.

Founded in 1919 and headquartered in Boston, Massachusetts, the American Meteorological Society is the nation’s premier organization for atmospheric, oceanic and hydrologic sciences. Its 13,000 members include researchers, educators, students, enthusiasts, broadcasters and others in these fields.

Supported by IBM, the AMS leadership academy works to sustain a diverse network of early-career achievers. Creative problem-solving, conflict resolution and enhancement of communication skills are major components of the curriculum.

Wood is a 2012 University of Arizona doctoral graduate in atmospheric science and remote sensing. She became an AMS member in 2008.

“Dr. Wood is the only MSU faculty member that has intentionally flown into the eye of a hurricane to collect data,” noted John Rodgers, interim head of the Department of Geosciences. Alongside experiences with hazardous weather systems, she has “excellent computer modeling skills and extensive knowledge of the application of satellite technologies to meteorology,” he said.

Her research “adds a very important component to our already outstanding meteorology program,” Rodgers added.

Wood said her leadership academy participation “already has borne fruit in the form of expanding connections with colleagues I may never have interacted with outside of such a program.” She also credits “strong support” from MSU colleagues and resources for the development of her chosen career.

Last year, she was selected to represent Mississippi at a congressional visit day organized in the nation’s capital by the American Geophysical Union. After helping stress the importance of continued federal science funding, she was asked by the AGU to also join its Climate Science Day program taking place on Capitol Hill in early 2018.

“I believe both experiences positively contributed to my selection for the ECLA, as well as the vision I have for my scientific career,” Wood said.

Academy membership involves a rigorous evaluation process, with documentation required of major accomplishments, successful experiences communicating across cultures and disciplines, and challenges involving weather, water and climate systems.

Wood is a Beaverton, Oregon, native who earned a bachelor’s degree in physics at Oregon State University. She also holds a master’s in atmospheric sciences from the University of Arizona. More biographical information may be read via the “About Us” link at the departmental website www.geosciences.msstate.edu.

Missions of the American Meteorological Society and Early Career Leadership Academy are online at www.ametsoc.org.

MSU’s College of Arts and Sciences includes more than 5,200 students, 300 full-time faculty members, nine doctoral programs and 25 academic majors offered in 14 departments. Complete details about the College of Arts and Sciences may be found at www.cas.msstate.edu.

MSU is Mississippi’s leading university, available online at www.msstate.edu.

On Friday March 9th, the OSU Astronomy Club and the Department of physics held the first Astronomy Open House of 2018! The Astronomy Club under Emily Simpson, Rachel Hausmann, Samantha Carrothers, Nathanial Miller, Leon Linebarger, Tyler Parsotan and many dedicated volunteers invited OSU students, adults and children to Weniger Hall to have fun with hands on demonstrations that help explain how astrophysical phenomena work.

Emily Simpson helps attendees determine which scientist they are most like.

Some of the activities included a room dedicated to Mars landing sites, by Rachel Hausmann, an activity dedicated to the mythology behind constellations, by Samantha Carrothers, a test created by Emily Simpson to determine which historical scientist you would be. We also had a presentation on remote telescope observations by local astronomers Tom Carrico, a presentation on telescope tuning by Stephen McGettigan, and the OSU Robotics Club show off their Mars rover!

The OSU Robotics Club show off their rover in Rachel Hausmann’s Mars Landing Sites Room.
Astronomy Tom captivated the attendees with how easy it is to get amazing astronomy photographs.

Over 100 people attended the event and got a free NASA poster for completing each activity! While we weren’t able to have telescopes out for this event due to the weather, future events will have night observations; especially as the weather gets better and better here in Oregon. In order to hear about our next event like us on facebook.com/osuastronights. We hope to see you there!

Trio Receives Prestigious Scialog Award To Study Collective Cancer Cell Dynamics

A cancerous tumor has cells that act as leaders as the tumor invades and degrades the body’s extracellular matrix, a collection of molecules secreted by healthy cells that provides for their structural and biochemical support. Little is known about how cancer cells become leader cells or how a hierarchy is established as the invasion moves forward.

Three scientists — Michelle Digman, University of California Irvine, Steve Pressé, Arizona State University, and Bo Sun, Oregon State University – have formed a collaboration to screen novel metabolic and rheological (i.e., flow) markers within an invading group of cancer cells. Specifically they aim to determine the probabilities of a cell belonging to a certain type within the invading tumor, and also determine how to eliminate leading cells, as well how new leaders are “elected.”

Among the three scientists, who have not worked together before, there is considerable expertise in live cell imaging and analysis, mathematical analysis and statistical modeling, and tumor patterning and cancer migration.

Digman, Presse and Sun formed their collaboration at the most recent Scialog: Molecules Come to Life conference organized by the private foundation Research Corporation for Science Advancement (RCSA).
Scialog is a combination of “science” plus “dialog.” The unique conference encourages early career scientists to form multidisciplinary teams to identify and tackle critical research challenges. The program is designed to fund highly innovative, but untested, ideas with the potential for high impact on challenges of global significance.

“Funding early stage, potentially high-impact research of this nature can be riskier than funding well-established lines of research,” notes RCSA Senior Program Director Richard Wiener, “but it represents an approach to accelerating the pace of breakthrough scientific discoveries.”

The $168,750 in funding for the trio’s research is provided by the Gordon and Betty Moore Foundation, which is co-sponsoring Scialog: Molecules Come to Life.
