Galactic Centre Pulsars with the SKAO
F. Abbate, A. Carleo, S. Chatterjee +18
The detection of a pulsar closely orbiting our Galaxy's supermassive black hole - Sagittarius~A* - is one of the ultimate prizes in pulsar astrophysics. The relativistic effects ex…
Full-polarization millimeter wavelength variability of Sagittarius A* during the 2018 EHT campaign
Ezequiel Albentosa-Ruiz, Jasmin E. Washington, Nicola Marchili +272
Sagittarius A* (Srg A*), the supermassive black hole at the center of the Milky Way, provides a unique laboratory to study accretion dynamics and plasma processes near the event ho…
Detection of Cyclotron Absorption in the Radio Emission of GPM 1839-10
Yunpeng Men, Ewan Barr, Yuanhong Qu +8
GPM 1839-10 is an intriguing long-period radio transient (LPT), distinguished by its activity spanning at least three decades and its highly unusual emission characteristics. These…
Long-term timing of the relativistic binary PSR J1906+0746
L. Vleeschower, B. W. Stappers, M. J. Keith +9
We conducted a timing analysis of over 18 years of data on the young ( kyr, \,ms) relativistic binary PSR~J1906+0746, using six radio telescopes: Arecibo…
Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…
