Astrophysics square kilometer array

What is Phase 1 of the Square Kilometre Array (SKA)?

Phase 1 of the Square Kilometre Array (SKA) will be a multi-purpose radio telescope, covering the frequency range from 50 MHz to 15 GHz that will play a major role in answering key questions in modern astrophysics and cosmology

What is the Square Kilometre Array?

Square Kilometre Array

The Square Kilometre Array (SKA) is an intergovernmental radio telescope project proposed to be built in Australia and South Africa

Conceived in the 1990s, and further developed and designed by the late-2010s, if built, it would have a total collecting area of approximately one square kilometre sometime in the 2020s

Will a'square Kilometre Array observatory' be the biggest telescope on Earth?

The first council meeting of the Square Kilometre Array Observatory has actioned plans that will lead to the biggest telescope on Earth being assembled over the coming decade

Member states approved a thousand pages of documents covering everything from the power to open a bank account to engaging with industrial contractors

Detector designed to detect a few GZK neutrinos at the South Pole

The Askaryan Radio Array (ARA) is a new detector designed to detect a few GZK neutrinos a year.It measures the enhanced radio-frequency radiation emitted during the interaction of the neutrino in Antarctic ice sheet.The detection is based on the Askaryan effect

An idea by Gurgen Askaryan

The Chicago Air Shower Array (CASA) was a significant ultra high high-energy astrophysics experiment operating in the 1990s.It consisted of a very large array of scintillation detectors located at Dugway Proving Grounds in Utah

USA

Approximately 80 kilometers southwest of Salt Lake City.The full CASA detector

Consisting of 1089 detectors began operating in 1992 in conjunction with a second instrument

The Michigan Muon Array (MIA)

Under the name CASA-MIA.MIA was made of 2500 square meters of buried muon detectors.At the time of its operation

CASA-MIA was the most sensitive experiment built to date in the study of gamma ray and cosmic ray interactions at energies above 100 TeV (10¹⁴ electronvolts).Research topics on data from this experiment covered a wide variety of physics issues

Including :

The search for gamma rays from Galactic sources (especially the Crab Nebula and the X-ray binaries Cygnus X-3 and Hercules X-1) and extragalactic sources (active Galactic nuclei and gamma-ray bursts)

The study of diffuse gamma-ray emission (an isotropic component or from the Galactic plane)

And measurements of the cosmic ray composition in the region from 100 to 100

000 TeV.For the topic of composition

CASA-MIA worked in conjunction with several other experiments at the same site:

The Broad Laterial Non-imaging Cherenkov Array (BLANCA)

The Dual Imaging Cherenkov Experiment (DICE) and the Fly's Eye HiRes prototype experiment.CASA-MIA operated continuously between 1992 and 1999.In summer 1999
