This week for DES, I'm working on reducing radio data from the Australian Square Kilometre Array Pathfinder as part of the EMU (Evolutionary Map of the Universe) survey. We’re identifying DES galaxies that are also radio galaxies. #DEST4TD

“Working deep inside the DES, one of the most refreshing ideas that I see on a daily basis is that the vast majority of our scientists work selflessly to produce and promote good science, and they do not allow the good science to selfishly promote themselves.” #DEST4TD

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.
