Study investigates mode switching phenomenon in the pulsar PSR J1326−6700

Study investigates mode switching phenomenon in the pulsar PSR J1326−6700 Using the Parkes 64-meter radio telescope, Chinese astronomers have performed a detailed study of a pulsar known as PSR J1326−6700. The results of this research provide more insights into the mode switching phenomenon observed in this pulsar. The study was published November 11 on arXiv.org. […]

Machine learning yields a breakthrough in the study of stellar nurseries

Machine learning yields a breakthrough in the study of stellar nurseries Artificial intelligence can make it possible to see astrophysical phenomena that were previously beyond reach. This has now been demonstrated by scientists from the CNRS, IRAM, Observatoire de Paris-PSL, Ecole Centrale Marseille and Ecole Centrale Lille, working together in the ORION-B program. In a […]

Past Supernovae Could be Written Into Tree Rings

Past Supernovae Could be Written Into Tree Rings A new study by CU Boulder geoscientist Robert Brakenridge shows how nearby supernovae could have disrupted Earth’s climate in the past The post Past Supernovae Could be Written Into Tree Rings appeared first on Universe Today.

Ten times more hyper-luminous galaxies observed than stars can produce

Ten times more hyper-luminous galaxies observed than stars can produce A team of astronomers led by SRON Netherlands Institute for Space Research has observed 10 times more hyper-luminous galaxies in the infrared than stars can produce according to the models. If the theory is correct, it means that stars alone cannot account for the brightness […]

Gravitational lenses measure universe expansion

Gravitational lenses measure universe expansion It’s one of the big cosmology debates: The universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey adapted an independent third measurement method using the light warping properties of galaxies predicted by Einstein. He published his findings in the Monthly Notices of […]
