The Rosetta stone of active galactic nuclei deciphered

A galaxy with at least one active supermassive black hole – named OJ 287 – has caused many irritations and questions in the past. The emitted radiation of this object spans a wide range – from the radio up to the highest ...

Finding galaxies with active nuclei

The nuclei of most galaxies host supermassive black holes with millions or even billions of solar-masses of material. Material in the vicinity of such black holes can accrete onto a torus of dust and gas around the black ...

Solution to the hyperfine puzzle in reach

Last year, physicists at TU Darmstadt cast doubt on our current understanding of the interplay between electrons and atomic nuclei, and are now upping the ante by proposing a solution to this so-called "hyperfine puzzle." ...

The structure of an active galactic nucleus

The nuclei of most galaxies host supermassive black holes containing millions to billions of solar-masses of material. The immediate environments of these black holes typically include a tori of dust and gas and, as material ...

Why is massive star formation quenched in galaxy centers?

The current cosmological model to explain the universe, the "Big Bang" model, aims to describe all observable phenomena, including the evolution of galaxies from earliest times to the present day. One of the major problems ...

New model to research activity around quasars, black holes

A University of Wyoming researcher played a key role in a study that suggests a newly developed computer model can more accurately explain the diversity of quasar broad emission line regions, which are the clouds of hot, ...
