The SDSS-V Black Hole Mapper Reverberation Mapping Project: Multi-Line Dynamical Modeling of a Highly Variable Active Galactic Nucleus with Decade-long Light Curves

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Zachary Stone, Yue Shen, Scott F. Anderson, Franz Bauer, W. N. Brandt | Summary: We present dynamical modeling of the broad-line region (BLR) for the highly variable AGN SDSS J141041.25+531849.0 ($z = 0.359$) using photometric and spectroscopic monitoring data from the Sloan Digital Sky Survey Reverberation Mapping […]

TOI-2490b- The most eccentric brown dwarf transiting in the brown dwarf desert

Posted by dbos MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Beth A. Henderson, Sarah L. Casewell, Andrés Jordán, Rafael Brahm, Thomas Henning | Summary: We report the discovery of the most eccentric transiting brown dwarf in the brown dwarf desert, TOI02490b. The brown dwarf desert is the lack of brown dwarfs around main sequence stars within $sim3$~AU […]

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

Posted by dbos Peking

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

Posted by dbos Peking

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

Posted by dbos Tokyo

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

Posted by dbos Peking

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

Posted by dbos Cambridge

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 […]
