(Phys.org)—For the first time, researchers have demonstrated that shining a nanosecond pulsed laser at the base of a 100-µm-long diamond needle can significantly enhance electron emission from the tip of the needle. The ...
By analyzing the historical light curve of blazar PKS 0405-385 from NASA's Fermi spacecraft, Chinese astronomers have detected quasi-periodic oscillation from this source. The discovery, presented in a paper published May ...
Using NASA's Chandra X-ray observatory, astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere have investigated an active galaxy known as Markarian 78. They report that the source exhibits termination ...

Researchers from the U.S. Naval Observatory and elsewhere have performed simultaneous observations of an active galactic nucleus (AGN) in the galaxy NGC 2992 using the Very Long Baseline Array (VLBA) and NASA's Swift spacecraft. ...
Using NASA's Chandra spacecraft, astronomers have inspected X-ray emission from the center of a young radio galaxy known as NGC 3894. Results of this study, presented in a paper published June 24 on the arXiv pre-print server, ...
Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted a study of two magnetars known as PSR J1622−4950 and 1E 1547.0−5408. Results of ...
Using NASA's Neil Gehrels Swift Observatory, astronomers have identified two new outbursts from the magnetar 1E 1048.1−5937. The newly detected events could shed more light on the nature of this source. The finding is detailed ...
Using ESA's XMM-Newton spacecraft, astronomers have investigated the nature of a peculiar pulsar wind nebula (PWN) in the supernova remnant (SNR) CTB 87. Results of the study, presented in a paper published November 26, shed ...
By analyzing archival data from the Suzaku X-ray satellite, astronomers have learned important information regarding thermal and non-thermal emission from the composite supernova remnant (SNR) designated MSH 15-56. Results ...
