Abstract: The Crab nebula pulsar was observed in 2009 January and December with a novel very fast optical photon counter, Iqueye, mounted at the ESO 3.5 m New Technology Telescope. Thanks to the ...

A pulsar is a neutron star, a super-dense stellar remnant that produces beams of radio waves and an energetic "wind" of particles. The pulsar and its wind move with supersonic speed through the ...

Apr. 16, 2025 — Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar ...

Abstract: We report the first results of imaging the Carina nebula (NGC 3372) with the Infrared Array Camera (IRAC ... EGOs are apparently poor tracers of outflow activity in strongly irradiated ...

Their discovery dates back over 60 years, but their exact source remains a mystery. Glennys Farrar, a physicist at New York University, proposes a novel explanation linked to neutron star mergers.

Their claim was soon challenged by another group of researchers, who argued it was more likely a neutron star. Now, after continued observation and analysis, the original team has gathered ...

This book summarizes the science to be carried out by the upcoming Cherenkov Telescope Array, a major ground-based gamma-ray observatory that will be constructed over the next six to eight years. The ...
