The Atacama Cosmology Telescope (ACT) collaboration, which includes researchers from the University of Toronto, recently ...

After five years of staring unblinking at the sky, the Atacama Cosmology Telescope (ACT) has compiled the most detailed map we've ever seen of the cosmic microwave background – the faint light that ...

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

Part of the new image that shows the polarization of the CMB. (ACT Collaboration; ESA/Planck Collaboration) The new map of the CMB gave a Hubble constant of 69.9 kilometers per second per megaparsec.

Using Planck polarization data, SFU Cosmology faculty Andrei Frolov and his collaborators created a model for large scale magnetic field of our galaxy, the Milky Way, which explains the observed ...

If our 13.8 billion-year-old cosmos could be considered middle-aged, researchers note these new images captured around its 380,000th birthday represent a snapshot of the universe as a newborn.

We get this map of the movement of the ... ACT measures the intensity and polarization of the light at five times the resolution of Planck and with around three times lower noise.

A telescope in Chile has spent years working on by far the most precise map of the earliest visible ... For the first time, the polarization of the signals can now be made out, which tells us ...

This piece of the new sky map that shows the vibration directions (or polarization ... That is a defining factor distinguishing ACT from Planck and other, earlier telescopes.” ...
