Going against the flow around a supermassive black hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this ...

The nature of obscured active galactic nuclei

Most galaxies host a supermassive black hole (SMBH) at their nucleus, one whose mass exceeds a million solar-masses. When material actively accretes onto the SMBH, associated processes can produce an active galactic nucleus ...

Mrk 1498 hosts a young and obscured AGN, study finds

An international team of astronomers has found that the giant radio galaxy (GRG) Mrk 1498 has a more complex nuclear structure than previously thought. By analyzing multi-wavelength observations of Mrk 1498, a young and obscured ...

Astronomers discover eight buried dual AGN candidates

Astronomers discovered eight buried dual AGN candidates, the largest sample of hidden accreting supermassive black holes in late stage galaxy mergers, selected using NASA's Wide-Field Infrared Survey Explorer (WISE) space ...

A new eye on the cosmos

How do galaxies form and evolve? And how do central supermassive black holes form in galaxies and influence their hosts? Those are two of the big questions that Tufts astronomers hope to answer when they start using a new, ...

Bright X-ray galactic nuclei

All massive galaxies are believed to host supermassive black holes (SMBH) at their centers that grow by accreting mass from their environment. The current picture also imagines that the black holes grow in size as their host ...
