The Transition from Galaxy-wide Gas Inflow to Outflow in Quasar Host Galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Zhifu Chen, Guilin Liu, Tinggui Wang, Luis C. Ho | Summary: Galactic-wide outflows driven by active galactic nuclei (AGNs) is a routinely invoked feedback mechanism in galaxy evolution models. Hitherto, the interplay among the interstellar gas on galactic scales, the propagation of AGN outflows […]

Effects from Dark Matter Halos on X-ray Pulsar Pulse Profiles

Kavli Affiliate: Lijing Shao | First 5 Authors: Yukun Liu, Hong-Bo Li, Yong Gao, Lijing Shao, Zexin Hu | Summary: Neutron stars (NSs) can capture dark matter (DM) particles because of their deep gravitational potential and high density. The accumulated DM can affect the properties of NSs. In this work we use a general relativistic […]

EfficientRAG: Efficient Retriever for Multi-Hop Question Answering

Kavli Affiliate: Jia Liu | First 5 Authors: Ziyuan Zhuang, Zhiyang Zhang, Sitao Cheng, Fangkai Yang, Jia Liu | Summary: Retrieval-augmented generation (RAG) methods encounter difficulties when addressing complex questions like multi-hop queries. While iterative retrieval methods improve performance by gathering additional information, current approaches often rely on multiple calls of large language models (LLMs). […]

Exploring the origin of cold gas and star formation in a rare population of strongly bulge-dominated early-type Galaxies

Kavli Affiliate: Jing Wang | First 5 Authors: Fujia Li, Enci Wang, Ming Zhu, Yingjie Peng, Jing Wang | Summary: We analyze the properties of a rare population, the strongly bulge-dominated early-type galaxies (referred to as sBDEs) with significant HI gas, using the databases from the FAST All Sky HI survey (FASHI) and the Arecibo […]

JWST/NIRSpec WIDE survey: a z=4.6 low-mass star-forming galaxy hosting a jet-driven shock with low ionisation and solar metallicity

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Vijay H. Mahatma, Giovanni Mazzolari, Stefano Carniani | Summary: We present NIRSpec/MSA observations from the JWST large-area survey WIDE, targeting the rest-frame UV-optical spectrum of Ulema, a radio-AGN host at redshift z=4.6348. The low-resolution prism spectrum displays high equivalent width nebular emission, with […]

Capturing Nonlinear Electron Dynamics with Fully Characterised Attosecond X-ray Pulses

Kavli Affiliate: Jia Liu | First 5 Authors: Lars Funke, Markus Ilchen, Kristina Dingel, Tommaso Mazza, Terence Mullins | Summary: Attosecond X-ray pulses are the key to studying electron dynamics at their natural time scale involving specific electronic states. They are promising to build the conceptual bridge between physical and chemical photo-reaction processes. Free-electron lasers […]
