Machine learning finds a surprising early galaxy

New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low 1.6% oxygen abundance, breaking the previous record of the lowest ...

Mergers between galaxies trigger activity in their core

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. ...

New 3-D map will help solve long-standing cosmic mysteries

A new study led by ANU has created a 3D map of the magnetic field in a small wedge of the Milky Way galaxy, paving the way for future discoveries that will improve our understanding of the origin and evolution of the Universe.

Astronomers develop new tool to find merging galaxies

Today, at the 233rd AAS meeting in Seattle, astronomers from the Sloan Digital Sky Survey (SDSS) announce that they have developed a new tool to find otherwise-hidden galaxy mergers in data from the Mapping Nearby Galaxies ...

Natural telescope sets new magnification record

Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution—gravitational lensing, predicted by Albert Einstein and observed many times by astronomers. Now, an ...

The material that obscures supermassive black holes

Cristina Ramos Almeida, researcher at the IAC, and Claudio Ricci, from the Institute of Astronomy of the Universidad Católica de Chile, have published a review in Nature Astronomy on the material that obscures active galactic ...
