Ohio University Department of Physics and Astronomy

Ohio University Department of Physics and Astronomy This is our online Common Room where we discuss topics and events relevant to our students, alumni, faculty, staff, and the greater science community.
(16)

Our faculty members are recognized leaders in their fields. At the core of our research are our graduate students, whom we work alongside in order to unlock the secrets of nature. Whether you do theoretical or experimental work, and whether you do it in Athens or on another continent, the work that you, as a student, perform during your time at Ohio University will have an impact on your chosen field. The education you receive will be first-rate, and the professional connections you develop while completing your degree will serve you well throughout your career. OUR GRADUATE STUDENTS At present, approximately eighty students are pursuing a Ph.D. through our program. They come from Ohio, other states across the US, and 30 countries worldwide. SUCCESS IN RESEARCH AND CAREERS Annual grant support from multiple agencies has recently exceeded $5.8M. Many of our faculty members are Fellows of the American Physical Society. Graduates go on to careers at national laboratories, in industry, and in academia, with a significant number finding post-doctoral employment at major research institutions and universities. Our alumni include several very successful scientists, including one Nobel Prize winner. RESEARCH FACILITIES Major research facilities include a 4.5 MV high-intensity tandem Van de Graaff accelerator with unique capabilities, used by visiting scientists from domestic and foreign universities, as well as national laboratories; a helium liquefaction and recovery system; and extensive laboratories housed in four buildings. We employ over twenty technical and research personnel. This enables timely, forefront research pertinent to systems ranging from nanochips to neutron stars. Theoretical work is carried out using on-campus PCs, Macs, and clusters, as well as on the 75 tera FLOP, 1625-node IBM cluster at the Ohio Supercomputer Center. Ohio University is a member institution at the MDM Observatory on Kitt Peak, Arizona. Our department also has extensive partnerships and collaborations with scientists, national laboratories, and universities around the world.

Mission: We aim to equip our students with an education in the fundamentals of the discipline; instill in them the knowledge and techniques required to carry out original research; nurture their development as independent scientists; and provide them with opportunities to grow as teachers and communicators.

S/O to Saw-Wai Hla and his team including physics doctoral student Tomás Rojas Solarzano and Ohio University Honors Tutorial College alumnus Ryan Tumbleson collaborated with colleagues at University of South Florida in publishing the paper, ‘Pushing the limits of 2D supramolecules’ in Nature Chemistry. The paper was mentioned in articles online in ScienceDaily, ScienMag, and Bioengineer.

(Paper summary: Researchers have reached a 'world record' in the development of two-dimensional supramolecules.)

At OHIO, Saw received a ‘Faculty High-Five’ which spotlights OHIO faculty for their participation in recent news stories that help shape national dialogue while elevating the University’s national profile.

Physics graduate student Sineth Premarathna studies single molecule investigations with Dr. Saw-Wai Hla. Here is his #OUVirtualExpo entry with 3 images. Nice job!

“Atom trapping with sexiphenyl molecules is realized by laterally manipulating the molecules onto individual silver atoms and up to three silver atoms have been trapped. We also demonstrate breaking of a silver dimer into individual silver atoms by atom trapping. STM manipulation experiments show that the molecule-metal complexes formed by the atom trapping are mechanically stable.” – @sineth_m

Nice write-up Extreme Science and Engineering Discovery Environment (XSEDE) on David Drabold's group where they determined the structure of a metallic glass by inference from experiment and accurate force calculations. These materials are used from everything from artificial heart valves to golf clubs.

Ohio University astrophysics graduate student Huei Sears serves as a student ambassador for the American Physical Society and is featured in the latest APS News in the article, 'APS Student Ambassadors Engage with Units' (April 2020 Vol. 29 No. 4).

Sears: “I know that joining APS allows students to present at APS conferences for an affordable price, but I've struggled in finding reasons to join APS for students who maybe aren't ready to present yet. This presentation gave me that information, and I now feel prepared to encourage all graduate students to join [APS].”

APS encourages both undergraduate and graduate students to consider becoming Ambassadors upon nomination from the chair of their physics department or from other faculty members. Students will also be able to apply to be an Ambassador online starting August 1, 2020.

“I study gamma-ray burst (GRB) host galaxies that are 26 billion light years away 💫 GRBs happen when some stars go supernova & they’re the brightest explosions in our universe💥 GRBs usually happen in places where there is ✨active star formation✨ @bobcatsdiscover #OUVirtualExpo

There are actually 2 (maybe 3) types of GRBs: short, long, & ~ultra-long~. Short GRBs usually last up to 2 seconds & they are caused by NS-NS or NS-BH mergers! 🌀 This was proved back in 2017 with @LIGO, @ego_virgo, @NASAFermi, & @ESA_Integral! 🎉

Long GRBs have lifetimes > 2s ⏱ These are the GRBs that I study! 💻 None have happened in the Milky Way in the last several billion years & thankfully none ever will! They’re very biased against metals (any element other than H), and our galaxy is metal-rich!

Ultra-long GRBs have lifetimes of over 10,000s (that’s nearly 3 hrs) 🕰 We don’t know a lot about these GRBs, and we haven’t detected a lot of them either. They might just be longer long GRBs (i.e. same progenitor type) but maybe not. ¯\_(ツ)_/¯

When we observe long GRBs, we care most about their afterglow 🌤 When the star explodes and lets out all this light & energy, it makes everything around it glow — kinda like how sunshine changes its color after it goes through stained glass! (📸: @elliesaysso)

Galaxies that are really far away are really difficult to observe. They’re often really faint & due to the expansion of the universe, their starlight gets redshifted into different parts of the 🌈electromagnetic spectrum🌈”

Music Precision on the Field and in the Lab

Engineering Physics major Sophia Medvid loves music and physics. As the first female Field Commander in the history of The Ohio University Marching 110, she leads by example on and off the field.

Check out this new video sponsored by our Department!

As a physicist, Medvid wants to know how things work. For her senior thesis project, she analyzed vibrations of the mellophone, one of the instruments she plays. She wanted to see if the vibrational modes significantly affect the sound coming from the mellophone. In what ways do the bell vibrations affect the sound? Her senior thesis project addresses this question.

Medvid’s physics lab precision and her research presentation led to an award of ‘Honorable Mention’ at the annual Society of Physics Undergraduate Research conference, sponsored by the Ohio University chapter of the Society of Physics Students.

She is a commanding presence at Ohio University in music and in science.

Congratulations Ohio University physics alumnus and inventor Azamat Orazbayev (Ph.D. 2013, with Dr. Charlotte Elster) for your issued patent!! Has it really been 7 years since you were part of our Department? Best wishes!!

Overview A common and major problem associated with the testing of emergency shutdown valves is the very stoppage of flow that the valves are designed to produce. While it is obviously required that an emergency shutdown valve stop a flow of material in a true emergency shutdown situation, testing o...
