![]() The “reverse shock” is a back-propagating “echo” as the relativistic blast wave from the initial explosion slams into surrounding gas and dust. In particular, the ATA observations, combined with higher frequency observations conducted with the Arcminute Microkelvin Imager Large Array (AMI-LA) telescope in the United Kingdom, provided the most detailed characterization yet realized of the “reverse shock” process in GRB explosions. ![]() Thanks to the rapid response from the ATA team and the unique capabilities of the ATA’s receivers and digital systems, the scientists been able to shed new light on the physical mechanisms at play in GRBs in unprecedented detail. The ATA was one of the first radio telescopes instruments to record data on this source, only a few hours after the event happened. “We owe this success to the original specification of the ATA and the refurbishment program that transformed its analog and digital capabilities.” Wael Farah, project scientist for the Allen Telescope Array. “It’s exciting to witness the ATA participating in a worldwide effort to study one of the most interesting and bright supernova explosions,” said Dr. These observations offer a rigorous testing ground for theoretical predictions about this interaction, and they provide valuable information for future rapid response instruments. They used data from radio telescopes worldwide, including the Allen Telescope Array (ATA), to investigate the violent interaction between the jet and circumstellar medium. The research team included astronomers from the UK, USA, Australia, the Netherlands, Italy, and South Africa. ![]() The international team recorded radio emissions just three hours after the explosion, providing unparalleled insight into the jet's properties as it rapidly evolved. The team was able to capture detailed information about a gamma radio burst (GRB) called the "Brightest of All Time" (BOAT), also known as GRB 221009A. March 28, 2023, Mountain View, CA – A team of astronomers from the SETI Institute, Oxford University, and other institutions worked together to study the earliest stages of the Universe's most powerful explosions. The ATA is operated by the SETI institute, designed as an instrument dedicated to technosignature searches, it has the potential to be a powerful facility for the study of transients. Locke, an early rancher in the area.The Allen Telescope Array (ATA) based in Hat Creek Radio Astronomy Observatory, California, USA. It’s one of the world's leading centers for astronomical research, teaching, and public education and outreach. The summit hosts the McDonald Observatory, an astronomical observatory built in 1932. Tucked away in the Davis Mountains range, the road to the summit was built on April 24, 1933. How do I get to the McDonald's observatory? ![]() The average gradient is 6.44%, with a maximum gradient of 11,4%. Over this distance the elevation gain is 176 meters. Starting at TX-118 road, the ascent is 2.73km (1.7 mile) long. Tucked away in central Jeff Davis County, the road to the summit is pretty steep. Is the road to Mount Locke in Texas steep? Locke, Spur 78 has the highest elevation at any point on the state highway system. It’s called Texas State Highway Spur 78 or Spur 78. The road to the summit is totally paved with steep grades.
