REBELS-25 is a massive, star-forming rotating disc galaxy [1] [2] with a redshift of 7.31. [3] It was discovered using the Atacama Large Millimeter/submillimeter Array (ALMA), [4] [5] notice of its discovery was published in the Monthly Notices of the Royal Astronomical Society. REBELS-25 existed just 700 million years after the Big Bang.

2024年5月9日 · These high resolution, high signal-to-noise observations allow us to study the sub-kpc morphology and kinematics of this massive (M∗ = 8+4−2 ×109M⊙) star-forming (SFR UV+IR = 199+101−63 M⊙yr−1) galaxy in the Epoch of Reionisation.

2024年10月7日 · Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old.

2024年5月20日 · At a redshift of 7.31, which corresponds to a luminosity distance of about 236 billion light years, REBELS-25 is an infrared luminous galaxy. It has a stellar mass of some 8 billion solar...

2024年10月7日 · Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old.

By comparing to other high spatial resolution cold gas kinematic studies, we find that dynamically cold discs seem to be more common in the high-redshift Universe than expected based on prevailing galaxy formation theories, which typically predict more turbulent and dispersion-dominated galaxies in the early Universe as an outcome of merger ...

2024年10月7日 · Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disk galaxy seems as orderly as present-day galaxies, but we see it as it was when the...

2024年10月7日 · Following this classification, we find that REBELS-25 is the most distant super cold disc galaxy observed to date. In the following, we first discuss our findings on this galaxy in more detail (Section 5.1) before placing REBELS-25 in context with other high resolution gas kinematic studies.

2024年10月16日 · The galaxy, which has been named REBELS-25, is far more orderly than the existing science suggests it should be for its age, according to research led by astronomers from Leiden University in...

2024年10月7日 · REBELS-25, a galaxy resembling the Milky Way found in the early universe, defies traditional models with its orderly structure, indicating rapid galactic evolution. Astronomers have discovered the most distant Milky-Way-like galaxy ever observed, named REBELS-25.
