Astrophysics: A direct view of Star/Disk Interactions

Artist’s impression of the streams of hot gas that build up stars. Matter from the surrounding protoplanetary disk, the birthplace of planets, is channeled onto the stellar surface by magnetic fields shocking the surface at supersonic velocity (Copyright: Mark A. Garlick).

A team including researchers from the Institute for Astrophysics of the University of Cologne has for the first time directly observed the columns of matter that build up newborn stars. This was observed in the young star TW Hydrae system located approximately 163 light years from Earth. This result was obtained with the Very Large Telescope Interferometer (VLTI) and its GRAVITY instrument of the European Southern Observatory (ESO) in Chile...

Synthetic Compound could serve as Prototype for Novel Class of Drugs to Treat Neurological Damage

Researchers from the German Center for Neurodegenerative Diseases (DZNE), UK and Japan have developed a neurologically acting protein and tested it in laboratory studies. In mice, the experimental compound ameliorated symptoms of certain neurological injuries and diseases, while on the microscopic level it was able to establish and repair connections between neurons. This proof-of-principle study suggests that biologics, which act on neuronal connectivity, could be of clinical use in the long term. The results are published in the journal Science.

A team of researchers with Google’s AI Quantum team (working with unspecified collaborators) has conducted the largest chemical simulation on a quantum computer to date. In their paper published in the journal Science, the group describes their work and why they believe it was a step forward in quantum computing. Xiao Yuan of Stanford University has written a Perspective piece outlining the potential benefits of quantum computer use to conduct chemical simulations and the work by the team at AI Quantum, published in the same journal issue.

Rare Encounters between Cosmic Heavyweights

SDSS J141637.44+003352.2, a dual quasar at a distance for which the light reaching us was emitted 4.6 billion years ago. The two quasars are 13,000 light years apart on the sky, placing them near the center of a single massive galaxy that appears to be part of a group, as shown by the neighboring galaxies in the left panel. In the lower panels, optical spectroscopy has revealed broad emission lines associated with each of the two quasars, indicating that the gas is moving at thousands of kilometers per second in the vicinity of two distinct supermassive black holes. The two quasars are different colors, due to different amounts of dust in front of them. Credit: Silverman et al.
