Lecture March 2nd: Gravitational Waves CHANGE OF LOCATION

Friday, March 2, 2018 - 7:30pm

NEW LOCATION: PHELPS HOSPITAL AUDITORIUM, Sleepy Hollow (just 3.2 miles from Pace)

Bright lights from gravitational wave sources: simulations of merging black holes and neutron star systems.

​Andrew MacFayden, Ph.D., Associate Professor of Physics, New York University

Gravitational waves are subtle ripples in space and time flowing through the universe. Albert Einstein predicted their existence in his famous theory of general relativity published in 1916, but it took a hundred years of strenuous effort for humans to detect them. In 2015, the LIGO interferometer detected gravitational waves from the inspiral and merger of two blacks hole leading to the 2017 Nobel prize in physics to LIGO's leaders. This past summer, on August 17, 2017, an even more exciting event for astronomers occurred: the merging of two neutron stars accompanied by a gamma-ray burst and a "kilonova" along with long lived afterglow radiation which is still being detected. Prof. MacFayden will discuss recent research on black hole mergers, including supermassive black holes, along with predictions for ongoing astronomical observations of the merging neutron star event.

Dr. MacFayden is Associate Professor of Physics at NYU, specializing in computational astrophysics. He obtained his degrees in astrophysics from Columbia (BA) and UC Santa Cruz (PhD) and was a postdoctoral fellow at Caltech and the Institute for Advanced Study in Princeton before coming to NYU.

Free and open to the public.

Change of location information:

We have been informed by Pace that they are hosting the Westchester High School basketball finals on Friday night and that parking will be extremely problematic, with potentially 1,000 cars seeking parking on campus. It is very likely that few spaces will be available in the lot outside of Lienhard Hall. As a result, we have decided to move the site of our WAA meeting and lecture to the Auditorium at Phelps Hospital, just 3.2 miles down Route 117 from Pace. Parking is available just outside of the Auditorium, which has excellent audiovisual equipment.

Phelps Hospital is located 5 minutes west of Pace on Route 117 and Route 9 (Broadway). Click here for an overview satellite image of the area.

To get to the Phelps Auditorium from Pace, drive west on Route 117 until you see the sign for Phelps on your left and Regeneron on your right. Keep going straight until the stop sign. Turn left and drive straight ahead about 500 feet behind the hospital, past the loading dock and Auditorium entrance to the parking lot on your right. The Auditorium entrance is up a few steps into the hospital; the Auditorium is immediately to your right upon entering the building. Click here for a detailed image of the route, which is marked in orange dots. Click here for a very detailed satellite image of the parking area and the auditorium entrance. And click here for a 3D view of the parking area and the Auditorium entrance.

If you are coming from Route 9, just turn onto the hospital property at the main entrance and go straight ahead, past the red brick building to the parking lot.

We apologize for any inconvenience, but we think that this is a much better solution than dealing with what is sure to be a traffic and parking nightmare at Pace. If you have any questions, send an email to eblasts@westchesterastronomers.org. If you get lost coming to the meeting, call (914) 548-8243.
