SOAR tracks spectroscopic evolution of historic LIGO discovery

Submitted by cbriceno on Mon, 2017-10-16 16:27

On August 17, 2017, Advanced LIGO and Virgo made the first detection of gravitational waves (GW) from a neutron star binary merger. Twelve hours after the GW signal, an electromagnetic wavelength counterpart—the first for any GW source—was identified within the 30 degree square localization region. The source was identified by the Dark Energy Camera on the 4-m Blanco Telescope, and several other groups.

Dr. Kathy Vivas, CTIO Astronomer, sends us this picture of the Desierto Florido (Flowering Desert) she took today, Aug 21, 2017, on the road to Cerro Tololo and Cerro Pachón. It shows the varied colors of the blooming flowers that grace the otherwise barren landscape, after this wet 2017 winter season.

Punching Above Its Weight, a Brown Dwarf Launches a Parsec-Scale Jet

Submitted by cbriceno on Thu, 2017-05-18 01:20

Astronomers using the SOAR telescope at the Cerro Tololo Inter-American Observatory report the discovery of a spectacular extended jet from a young brown dwarf. With masses too low to sustain hydrogen fusion in their interiors, brown dwarfs occupy the mass range between stars and giant planets. While young stars are commonly found to launch jets that extend over a light year or more, this is the first jet with a similar extent detected from a brown dwarf. The result lends new insight into how substellar objects form.
