Wandering black holes

Every massive galaxy is believed to host a supermassive black hole (SMBH) at its center. Its mass is correlated with the mass of the inner regions of its host (and also with some other properties), probably because the SMBH ...

Black hole size revealed by its eating pattern

The feeding patterns of black holes offer insight into their size, researchers report. A new study revealed that the flickering in the brightness observed in actively feeding supermassive black holes is related to their mass.

New animations breathe life into complex scientific concepts

The fundamental process of cellular respiration—how cells make energy—has been brought to life in a new series of biomedical animations created by wehi.tv, in partnership with HHMI Biointeractive, an initiative of the ...

Supermassive black holes put a brake on stellar births

Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from a large sky survey, the ...
