For a couple hours each collaboration meeting, we put down the computers and put on the cleats for the collaboration football (soccer) match! We had at least 10^3 kicks of the ball, and given the systematics involved, we report no detections of non-GR gravitational effects on the ball. #DESatPenn ... See MoreSee Less

We're into Day 3 of our biannual collaboration meeting. For much of the week, we split into our various science working groups (www.darkenergysurvey.org/collaboration-and-sponsors/) to discuss ongoing and future analyses. This picture comes from the Large-Scale Structure (LSS) session. #DESatPenn ... See MoreSee Less

Observações com a câmera DECam revelam a natureza de evento de ondas gravitacionais

October 16, 2017 1:52 pm

Cientistas usando a câmera do levantamento Dark Energy Survey (DES) capturaram imagens do resultado de uma colisão entre estrelas de nêutrons, evento que produziu a detecção de onda gravitacional mais recente (GW170817) pelos observatórios LIGO e Virgo. Uma equipe de cientistas usando a Dark Energy Camera (DECam), a principal ferramenta de observação do Dark Energy Survey, estão entre os primeiros a observar as consequências de um surto de ondas gravitacional detectado recentemente, registrando imagens da primeira explosão confirmada como consequência da fusão de duas estrelas de nêutrons. Esse violento processo de fusão, ocorrido há 130 milhões de anos em uma galáxia próxima à nossa (NGC 4993), é a fonte das ondas gravitacionais detectadas pelo Observatório Interferométrico de Ondas Gravitacionais (LIGO) e Interferômetro Virgo em 17 de agosto.
