This is same as www.gigapan.com/gigapans/116511, except the image has been enhanced with a gamma correction(performed on the floating number pixel brightness, before converted to an RGB image). Gamma=1.2. With the gamma correction, the brighter end(high density region) is represented with more luminosity dyna...

This is MassiveBlack II projected temperature/density map unfolded to a rectangle of 428Mpc/h x 245Mpc/h. Without any gamma corrections, the dense regions are missing contrasts due to the longer projection along line of sight. each pixel represents 2kpc/hx2kpc/h. Our galaxy will be roughly covering an area of 10p...

MassiveBlack II is the smaller cousin of MassiveBlack, a cosmological simulation ran at NISC Kraken by Researchers at McWilliam Cosmology Center at Carnegie Mellon University. In MassiveBlack II, 5.3 billion gas particles and 5.3 billion dark matter particles represents the baryon and dark matter in a cubic patch ...

An (incomplete) OCTtree is constructed with the particles in a cosmology SPH(smoothed particle hydrodynamics) simulation. This octtree will be used as a smoothing kernel to reconstruct a density field out of SPH particles. The density field field will then be used in cosmic radiative transfer study, similar to Feng...

This image, the first one of terapixel size uploaded to the GigaPan website was created by Yu Feng and Rupert Croft (McWilliams Center for Cosmology, Carnegie Mellon University, www.cmu.edu/cosmology
) from a hydrodynamic supercomputer simulation of cosmic structure using the P-Gadget code carried out by Tizian...-
