An international team has discovered a giant spiral disk galaxy in the early cosmos which is three times larger than similar ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy ...

It is therefore not surprising that we are living in the dark-energy-dominated epoch, and the "Why now?" cosmological coincidence problem is also effectively resolved. As the universe's mass ...

So, the total model entropy increases over cosmic time because the Hubble radius grows steadily at the speed of light. Thus, ...

I simulate galaxies and their galactic halos using cosmological hydrodynamical simulations ... (from the radio to the X-ray), redshift (the present-day Universe to the Epoch of Reionization), or ...
