Widespread steep X-ray spectra of luminous quasars and their implications for future X-ray surveys
A. Tortosa, L. Zappacosta, E. Piconcelli +54
Luminous quasars (QSOs) at the Epoch of Reionization (EoR, ) host billion-solar-mass black holes assembled within the first Gyr of cosmic time. Their X-ray emission prob…
PixelUMM: Encoder-Free Unified Image and Video Understanding and Generation
Cong Wei, Xuanchi Ren, Bryan Chu +8
Unified Multimodal Models (UMMs) often rely on separate visual representations for understanding and generation, increasing visual context length and complicating integration with…
LongLive-Plug: Once-for-All Distillation for Video Generation
Shuai Yang, Luozhou Wang, Wei Huang +9
Video diffusion models are increasingly developed into specialized models for diverse downstream tasks, and this development often includes a distillation stage, for example to acc…
Context-Matched Distillation: Teacher Causality for Autoregressive Video Distillation
Hmrishav Bandyopadhyay, Xuanchi Ren, Zijian Huang +7
Interactive autoregressive video generation demands both low-latency rollouts and precise online control. Few-step distillation accelerates generation by reducing denoising steps,…
