Is there a dark energy camera?
The Dark Energy Camera is a new imager with a 2.2-degree diameter field of view mounted at the prime focus of the Victor M. Blanco 4-meter telescope on Cerro Tololo near La Serena, Chile.
What is the purpose of the Dark Energy Camera?
The science requirements of DES drive the construction of the Dark Energy Camera (DECam). DES will look deeply into the universe, observing galaxies at great distances to record their motion and conditions in the distant past.
How is dark energy measured?
DES scientists used two methods to measure dark matter. First, they created maps of galaxy positions as tracers, and second, they precisely measured the shapes of 26 million galaxies to directly map the patterns of dark matter over billions of light-years, using a technique called gravitational lensing.
What is dark energy and dark matter?
Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe.
What is a DECam?
DECam, short for the Dark Energy Camera, is a large camera built to replace the previous prime focus camera on the Victor M. Blanco Telescope. The camera consists of three major components: mechanics, optics, and CCDs.
Is gravitational lensing real?
A gravitational lens can occur when a huge amount of matter, like a cluster of galaxies, creates a gravitational field that distorts and magnifies the light from distant galaxies that are behind it but in the same line of sight. The effect is like looking through a giant magnifying glass.
What is the evidence for dark energy?
Evidence of existence. The evidence for dark energy is indirect but comes from three independent sources: Distance measurements and their relation to redshift, which suggest the universe has expanded more in the latter half of its life.
Where is the Dark Energy Camera?
Cerro Tololo Inter-American Observatory
The instrument used by DES is the newly constructed Dark Energy Camera (DECam), which is mounted on the Victor M. Blanco 4-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO) in the Chilean Andes.
What is dark energy in simple terms?
Dark energy is the name given to the mysterious force that’s causing the rate of expansion of our universe to accelerate over time, rather than to slow down. That’s contrary to what one might expect from a universe that began in a Big Bang. Astronomers in the 20th century learned the universe is expanding.
Can dark energy harnessed?
Probably not. Before scientists could even attempt to assess the possibility of harnessing dark energy as a source of electricity, we’d have to find it. If we were able to harness the power of dark energy, however, we’d be using it for a lot more than simply powering our iPhone.
Who studies dark matter?
Astronomers study the distribution of dark matter in the universe by looking at the clustering of material and the motion of objects in the universe. Particle physicists, on the other hand, are on a quest to detect the fundamental particles making up dark matter.
What is fire Decam system?
24/7 Fire Monitoring Service (DECAM) Our DECAM system provides vital enhancement to any fire alarm panel. Linked to a round-the-clock Central Monitoring Centre (CMC), the system provides 24 hour vigilance over the people and things that are vital to you.
