On February 11th, 2016 (10:30AM EST), scientists from Caltech, MIT and the LIGO Scientific Collaboration together with representatives of the National Science Foundation, announced in a live press conference, the first direct detection of gravitational waves.
The event detected, named GW150914, was produced by two colliding black holes, inspariling and merging together. This signal was detected by LIGO on September 14th, 2015.
Details of this discovery can be found in the following papers:
Many of the researchers running simulations and analysing data in several of our clusters are directly involved in the efforts for accurately modelling, simulating and detecting gravitational wave signals.
As a matter of fact, one of the simulations used for visualizing one of the movies screened during the announcement of the discovery of gravitational waves, was performed on SciNet’s General Purpose Cluster (GPC).
“The first detection of gravitational waves passing through Earth is a tremendous discovery. These waves were generated by never before observed astronomical objects, colliding black holes. I am very grateful for SciNet and Compute Canada to provide the computing resources needed to explore the properties of binary black holes, research that was instrumental in building the waveform-templates that LIGO used in its momentous discovery.”
— Prof. Harald Pfeiffer (Canadian Institute for Theoretical Astrophysics, University of Toronto)
These simulations were performed by solving Einstein’s equations of General Relativity using a code co-developed on SciNet
, by the SXS/CITA collaboration
Another of the videos
displayed on the press-conf, was also produced by solving Einstein equations using this same computer code co-developed on SciNet
by the SXS/CITA collaboration

Dear SciNet administrators,
If you are still into keeping track of SciNet supported publications, here is one of mine that just got published. Thanks for the excellent work of all the SciNet staff members! Your team is really one of the most important reasons why this paper is even possible!

Dear SciNet staff,
I am writing this letter to thank you all for your dedicated effort in providing SciNet users with such an excellent support service.
I have been using you High Performance Computing systems since the very first year of production, and was always impressed by the amount of help I received from your programming staff.
Being at the University of Toronto for five years, I had the chance to have close contact with the staff, I had to opportunity to sit down about a dozen time with one of your experts, which would patiently help me with a wide variety of programming aspects. “I should have come here last year!!!” would I say to myself every time.

I just wanted to personally thank you for all your help over the past couple of years with all things Scinet. I just convocated and I am now working with Dr. Martins as a post-doc at the University of Michigan. After using a couple of over HPC systems down here I can honestly say you guys really got it right and run a top-notch HPC system.

Hi both [Jonathan and Ramses],
I would like to thank you both for a very informative course, one from which I have learnt a lot and which is already been useful in my work. I only wish I had had more time to devote to it.

For the last two years I’ve been a post-doctoral fellow with Thomson’s group and a SciNet user. Now, when my fellowship has came to an end (don’t close my account just yet – I need to finish some things), I wanted to say goodbye. I also wanted to say that I’ve seen a lot of computer system admins and mangers, from both sides. I have to say that you guys are the best of all these. Really, until I started using SciNet, I have never realized that the computer people can be responsive, professional and nice – in the best case scenario I thought I needed to pick two out of three. I was wrong, and I can hardly think of any way that SciNet staff can be better. You were nice, responded fast and to the point, and didn’t show your annoyance with users that clearly haven’t read Wiki (which you maintained great). The courses that you offered were great and even the upgrades actually made life easier.
So, thank you for your work, and if you want to forward it to the people that are responsible for the funding – feel free. People that are responsible for the funding – SciNet staff does a wonderful job. Keep that in mind.
All the best

Hi Ramses and Jonathan,
Thank you very much for setting up the [Scientific Computing] course! It was very educational, and will almost certainly be very practical in my future research. Hopefully many others will benefit from it in future years!

I just wanted to send you a quick note to say thanks for all the help you’ve given me over the last few weeks. I managed to get all the data I needed for the presentation and I think it went ok.I couldn’t have done it without your quick replies and understanding, not to mention the reservation on the TCS!

Dear SciNet staff:
On behalf of my entire lab, I would like to express my appreciation for your efforts to keep the SciNet cluster operational. As you know, we rely very heavily on SciNet for our research. We appreciate that sporadic service outages are unavoidable and should be expected. We are consistently impressed by the speed at which the SciNet GPC is restored to active service whenever an outage occurs and I wanted to let you know how much we appreciate all of your hard work. For this, my entire group thanks all SciNet staff, especially Ching-Hsing and Joseph, who I understand were up all night restoring the computer.
