DEScientist Jessie Muir created this great drawing depicting gravitational lensing! Left: what a group of galaxies would look like if their light arrived uninterrupted at our telescope. Right: what we actually see after light from those galaxies is deflected due to gravitational lensing by other galaxies (in white). The overall effect tends to have galaxies look stretched or 'sheared' into a circular pattern around the 'lens' galaxies causing the deflections.

Most of the matter in the Universe is dark matter, which cannot be seen directly. However, all matter cause gravitational lensing. Studying these gravitational effects is one of the main ways DES is able to study dark matter (in this case, the dark matter and visible matter in the 'lens' galaxies in white.)

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.
