Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope
Hendrik Mueller, Sebastiano D. von Fellenberg, Ai-Ling Zeng +275
The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact…
Echoes in Different Tempo: Long-Term Monitoring of Crab Echoes with CHIME
Thierry Serafin Nadeau, Marten H. van Kerkwijk, Jing Luo +4
The Crab Pulsar is known to feature plasma lensing events known as echoes. These events are characterized by additional components in the pulse profile which are produced by additi…
Reaching diffraction-limited localization with coherent PTAs
Anna C. Tsai, Dylan L. Jow, Ue-Li Pen
Current pulsar timing array (PTA) analyses do not take full advantage of pulsar distance information, thereby missing out on improved angular resolution and on a potential factor-o…
Back-End System of BURSTT
Kai-Yang Lin, Chih-Yi Wen, Homin Jiang +7
The Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) is a new-generation wide-angle radio telescope specifically designed to survey Fast Radio Bursts (FRBs), energetic m…
Detection of the Cosmological 21 cm Signal in Auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +36
We present the first detection of the cosmological 21 cm intensity mapping signal in auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Usin…
Discovery of a 21 cm absorption system at z=2.327 with CHIME
CHIME Collaboration, Mandana Amiri, Arnab Chakraborty +19
We report the detection of a new 21 cm absorption system associated with the radio source NVSS J164725+375218 at a redshift of z=2.327, identified through a pilot survey conducted…
