Early Mini-Halos and Protogalaxies
How the first galaxies were born in small, dark matter “halos.” Long before the majestic spirals and giant ellipticals we see today, there existed smaller, simpler structures at the dawn...

Gravitational Clumping and Density Fluctuations
How tiny density contrasts grew under gravity, laying the groundwork for stars, galaxies, and clusters Since the Big Bang, the universe has transformed from an almost perfectly smooth state into...

The Emergence of Large-Scale Structures
From the scorching aftermath of the Big Bang to the intricate tapestry of galaxies and galaxy clusters spread across billions of light years, cosmic structure has evolved dramatically. Early on,...

Reionization: Ending the Dark Ages
How ultraviolet light from the first stars and galaxies reionized hydrogen, making the universe transparent again In the timeline of cosmic history, reionization marks the end of the so-called Dark...

The Dark Ages and First Structures
A period before stars existed, when matter began gravitationally clumping into denser regions Following the epoch of recombination—when the universe became transparent to radiation and the Cosmic Microwave Background (CMB)...
