Dave Principe, AST Alumni, is coauthor of a new paper in Nature. The paper concerns the detection of the so-called "snow line" in a planet-forming disk orbiting a very young (less than 1 million year old) star, using the powerful new Atacama Large Millimeter Array (ALMA). The "snow line" is thought to mark the position in a disk where coatings of volatile ices (CO, CO2, methanol, etc) can form on dust grains, setting the stage for the buildup of the icy cores of Jupiter-like planets.
Rochester Institute of Technology undergraduates are making a “compass” for rockets using a new kind of detector technology. The instrument will fly on a NASA technology demonstration mission later this year. The team’s mentors are Zemcov; Dorian Patru, professor of electrical engineering; and Chi Nguyen, a Ph.D. student from Vietnam in the astrophysical sciences and technology graduate program.
The student team is designing, building—and deploying—a telescope and camera that will orient the rocket payload based on the images of stars. RIT’s Cryogenic Star Tracking Attitude Regulation System is funded by a $200,000 grant from NASA’s Undergraduate Student Instrument Project Flight Research Opportunity program. The NASA program is designed to give undergraduates experience developing and flying experiments relevant to NASA’s mission. Full Article
Rochester Institute of Technology professors have developed a faster, more accurate way to assess gravitational wave signals and infer the astronomical sources that made them. Their method directly compares data from the Laser Interferometer Gravitational-wave Observatory to cutting-edge numerical simulations of binary black holes, including simulations performed at RIT.
In a paper available online, the LIGO Scientific Collaboration reanalyzed the first gravitational wave detections using this method. Insights from these simulations indicate that the first detected black holes were slightly more similar in mass than previously thought. RIT authors on the paper include faculty Richard O’Shaughnessy, Manuela Campanelli, Carlos Lousto, John Whelan and Yosef Zlochower; postdoctoral researcher James Healy; graduate students Jacob Lange and Yuanhao Zhang; and undergraduate student Monica Rizzo and recent graduate Jackson Henry. They are all members of RIT’s Center for Computational Relativity and Gravitation and the LIGO Scientific Collaboration... Full Article
Gravitational waves from a second pair of colliding black holes has validated the landmark discovery from earlier this year that confirmed Einstein’s general theory of relativity. Rochester Institute of Technology scientists contributed to the initial breakthrough and to the second discovery announced Wednesday by the Laser Interferometer Gravitational-wave Observatory.
The second gravitational wave was observed by the LIGO Scientific Collaboration and the Virgo Collaboration on Dec. 26, 2015, toward the end of the first science run of the Advanced LIGO detectors. The findings, which will appear in the journal Physical Review Letters, validate the new field of gravitational wave astronomy and reveal diversity of size and spin among black holes in the universe.
Four AST program faculty and their research team contributed to LIGO’s breakthrough discovery, which detected signals emitted from a black-hole collision 1.3 billion light years away. RIT’s LIGO team is preparing for the first-ever black-hole census when LIGO begins its second operational run this summer. Full Article

RIT's Senior Lecturer Brian Koberlein, Professor Michael Richmond, and Ph.D. student Kevin Cooke join radio host Evan Dawson's Monthly Science Roundtable for adiscussion about a possible Planet Nine beyond the orbit of Pluto. The evidence for the claim as well as possible problems with the evidence are examined as they take questions from the audience about the claim and planetary science.
