Detection of pulses from the Vela pulsar at millimeter wavelengths with phased ALMA

Kuo Liu, Andre Young, Robert Wharton +20

We report on the first detection of pulsed radio emission from a radio pulsar with the ALMA telescope. The detection was made in the Band-3 frequency range (85-101 GHz) using ALMA…

First M87 Event Horizon Telescope Results. VI. The Shadow and Mass of the Central Black Hole

The Event Horizon Telescope Collaboration

We present measurements of the properties of the central radio source in M87 using Event Horizon Telescope data obtained during the 2017 campaign. We develop and fit geometric cres…

FAST ultra-wideband observation of abnormal emission-shift events of PSR B0919+06

Ye-Zhao Yu, Bo Peng, Kuo Liu +6

PSR B0919+06 is known for its abnormal emission phenomenon, where the pulse emission window occasionally shifts progressively in longitude and returns afterwards. The physical mech…
