Periodic volcanism may have triggered multiple Jurassic extinctions
Severe environmental crises led to a series of large-scale extinction events in the Jurassic period 178-186 million years (myr) ago. The turmoil has been ascribed to the abundant release of volcanic gases, but the temporal link between volcanism and.....»»
Thirteen new pulsars discovered with MeerKAT
Using the MeerKAT radio telescope, an international team of astronomers has detected 13 new pulsars in the globular cluster NGC 1851. Twelve of them turned out to be millisecond pulsars (MSPs). The discovery was reported March 23 on the arXiv pre-pri.....»»
Quasi-periodic oscillations detected in pulsar LMC X-4
Using ESA's XMM-Newton telescope, Indian astronomers have performed X-ray observations of a binary X-ray pulsar known as LMC X-4. The observational campaign resulted in the detection of quasi-periodic oscillations (QPOs) in this source. The finding i.....»»
