Astrophysicist Chornock Contributes to Discovery of Neutron Star Merger

The image sequence above shows infrared imaging from the FLAMINGOS-2 imager and spectrograph for a period of over two weeks. The top row features images in the h-band, a shorter (bluer) wavelength of infrared light. The bottom row focuses mostly on k-band images, which are longer (redder) wavelengths of light. This sequence reveals how the object became redder as it faded from view.
