To make sure we don’t unintentionally bias DES dark energy constraints towards results we expect, we transform the data to look like it comes from a different Universe. When we finally reveal the real result, it’s very exciting — like opening a present! #darkbites

This paper introduces the method we use to transform the data: arxiv.org/pdf/1911.05929.pdf

Cosmologists and DEScientists will recognize many incredible details across this #darkbite! Our international zoom discussions, the 'contour plots' we use to interpret our results, and even some of our Chilean neighbors, the viscachas, make an appearance. ... See MoreSee Less

Timeline PhotosA Stellar Storm - At first glance, it looks as though storm clouds are gathering over the Víctor M. Blanco 4-meter Telescope. Situated at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab, the Blanco experiences few stormy nights at its location near the arid Chilean Atacama Desert. The dark cloud-like structures pictured here are in fact dusty areas of the Milky Way that absorb visible light. The bright glittering fringes are not lightning, but thousands of stars — just some of the billions within our galaxy.

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.
