Abstract: The recent LIGO detections of merging black holes represent the culmination of decades of research into gravitational waves (GWs). One well-known seminal work by Peters and Mathews predicted the GW luminosity of eccentric binaries to leading post-Newtonian (PN) order. Driven largely by the desire to detect GWs from inspirals, the Peters-Mathews work has subsequently been extended through 3.5PN. Less well-known is work by Taylor, which is directly analogous to the Peters-Mathews result, except for scattering binaries. This work has only been extended by one PN order.
@ LIGO Livingston
Gr@v members Pedro Cunha and Carlos Herdeiro at the LIGO LIvingston Control Room, in the state of Louisiana, USA, during a visit to the site. More exciting news should be announced in the summer by the collaboration!

COST Action "Gravitational Waves, black holes and fundamental physics"
The COST Action 16104 on "Gravitational Waves, black holes and fundamental physics" has been approved within the EU Framework Program Horizon 2020. The action is led by Prof. Vitor Cardoso and our group participated in the network of proposers. C. Herdeiro is a member of the management committee.
Interview to Porto Canal
For the second time C. Herdeiro was the guest interviewee of Porto Canal's "Mentes que Brilham". Watch and listen to the conversation (from minute 18 onwards) (Watch and listen to the first interview) with interviewer Cláudia Fonseca about black holes and some of the research work made at Gr@v in this area.
From Infinitely Large to Infinitely Small
Gr@v member António P. Morais gave a talk at Escola Secundária José Régio in Vila do Conde with title "Do Infinitamente Grande ao Infinitamente Pequeno - uma jornada pelas interações fundamentais na natureza". António was an invited speaker to participate in a sequence of seminars entitled "A Biblioteca convida...", and presented to 11th and 12th grade Science and Technology students the four fundamental interactions in nature and how have they shaped our Universe.
