Nearest radio galaxy tuned in

Nearby Centaurus A contains a supermassive black hole that powers a jet of relativistic particles. Using the Event Horizon Telescope, Michael Janssen et al. image substructures down to the base of the jet, revealing a hollow bi-cone with extremely bright edges — much like the jet in the more massive M87.

    Without a proper accounting of known and unknown systematics and uncertainties, combining information across multiple surveys, wavelengths, and detectors may be risky. Realizing the true potential of multi-messenger and panchromatic astrophysics requires getting data integration right.

    Recent observations show that some galaxies exist that have already run out of fuel only a few billion years after the Big Bang, challenging the current view on how galaxies form and evolve in a cold dark-matter-dominated Universe.

    New extremely high-resolution observations of the radio jets of the active galaxy Centaurus A have revealed striking brightening at the jet edges. This may be a common feature of jet outflows from active galaxies, but its origin remains unclear.

    The fate of galaxies is predominantly determined by their dark matter halo mass. However, recent simulations confirm an important role for the formation history, revealing an intricate relation between galaxies’ central supermassive black holes and the colours of their hosts.

    The short lifespan of software puts a time limit on the reproducibility of computational research. To extend software longevity, guidelines and tools to preserve scientific workflows and analysis are helpful, but the challenge is to get researchers to use them.
