Over the Memory Wall, Into the Instruction Wall: The New Bottleneck in GPU Data Processing
Sven Hepkema, Bowen Wu, Christos Kozyrakis +2
Datacenter GPUs have seen an order-of-magnitude increase in memory bandwidth with the adoption of newer generations of HBM. Meanwhile, GPU database systems are gaining traction, ma…
Simultaneous radio, optical and X-ray monitoring of hard X-ray selected AGN: a variability study
L. Hernández-GarcÃa, F. Panessa, D. Williams-Baldwin +2
AGN emission is intrinsically variable across the electromagnetic spectrum. Mapping the coupling between the accretion disk, the X-ray corona, and ejection flows is key to understa…
The SKA-VLBI Perspective on Radio-Quiet AGN
Francesca Panessa, Tao An, James Petley +21
The accretion-ejection mechanism in Active Galactic Nuclei (AGN) remains a central open problem in astrophysics, tied to the role of AGN feedback in galaxy formation and evolution.…
The PARADIGM Project II: Characterising Nuclear and Diffuse Radio Components in Local U/LIRGs
Geferson Lucatelli, Rob Beswick, Javier Moldón +14
Disentangling SF and AGN emission is essential for understanding galaxy evolution, yet remains challenging in merging systems where both processes are enhanced and spatially intert…
The Homogeneous MeerKAT and Swift/XRT X-ray Binary Radio:X-ray Plane
Justine Crook-Mansour, Rob Fender, Andrew Hughes +22
During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the c…
LeMMINGs VII: 5 GHz, 50 mas e-MERLIN observations of a statistically complete sample of nearby AGN
D. R. A. Williams-Baldwin, R. D. Baldi, R. J. Beswick +36
We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs), the deepest stati…
