Cascade: GPU-Accelerated Out-of-Core Suffix Array Construction for LLM Corpora
Jamshed Khan, Prashant Pandey
Suffix arrays over LLM (pre)training corpora underpin deduplication, contamination testing, n-gram statistics, and training-data attribution, and every new corpus or tokenizer need…
A Decade-Scale Ionization Echo of Black-Hole Accretion in Galactic Nuclei
Wei-Jian Guo, Shuo Zhai, Chen Hu +16
Circumnuclear structures in active galactic nuclei respond to accretion variability over different spatial and temporal scales, but whether compact narrow-line gas responds on deca…
Observations of a Possible Transient Magnetically Arrested Accretion State in a Nearby Quasar: OQ208
Brian Punsly, Cormac Reynolds, Paola Marziani +12
OQ208 is a nearby, partially obscured quasar (z=0.077) that is a young, bright, parsec scale radio source. We assemble archival and new high frequency VLBA and VLA observations and…
The X-ray weakness of Little Red Dots and JWST-selected AGN: comparison with local AGN in different accretion regimes
A. Tortosa, C. Ricci, P. Du +5
We investigate the origin of the observed X-ray weakness in high z LRDs and other JWST-selected broad line AGN by comparing their X-ray and optical properties with those of a diver…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XV. Reverberation Mapping of Mg II Emission Lines
Hua-Rui Bai, Pu Du, Chen Hu +25
As the 15th paper in a series reporting on a large reverberation mapping (RM) campaign of super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs),…
Little red dots as embryos of active galactic nuclei
Jian-Min Wang, Yi-Lin Wang, Yong-Jie Chen +7
As an unprecedented large population in the early universe, the JWST-discovered little red dots (LRDs) have garnered much attention for formation of massive black holes and galaxie…
