Kavli Affiliate: Kejia Lee | First 5 Authors: Jinchen Jiang, Shunshun Cao, Kejia Lee, Bojun Wang, Heng Xu | Summary: We use the Five-hundred-meter Aperture Spherical radio Telescope (FAST) to observe the bright millisecond pulsar (MSP) PSR B1937+21 (J1939+2134) and record the data in the band from 1.0 GHz to 1.5 GHz. We measure the […]
Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Yan-Rong Li, Jinyi Shangguan, Jian-Min Wang, Ric Davies, Daryl J. Santos | Summary: The geometric distances of active galactic nuclei (AGNs) are challenging to measure because of their exceptionally compact structure yet vast cosmic distances. A combination of spectroastrometry and reverberation mapping (SARM) of broad-line regions (BLRs) […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Wen-Li Yuan, Bikai Gao, Yan Yan, Renxin Xu, | Summary: Using the parity doublet model (PDM) for hadronic matter and a modified Nambu-Jona-Lasinio (NJL) model for quark matter, we investigate the potential existence of two- and three-flavor quark matter in neutron star cores. Both models respect chiral […]
Dong Yang, Jing Wang, Zhijie Qu, Zezhong Liang, Xuchen Lin | Summary: [[{“value”:”We present a statistical study of the neutral atomic hydrogen (HI) gas extending into the circumgalactic medium perpendicular to the disk for 7 edge-on galaxies with inclinations above $85^{circ}$ from the FEASTS program with a $3sigma$ ($20,text{km},text{s}^{-1}$) column density ($N_{text{HI}}$) depth of $5times10^{17} […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Patrick D. Sheehan, Doug Johnstone, Carlos Contreras Peña, Seonjae Lee, Gregory Herczeg | Summary: The JCMT Transient Survey recently discovered that the Class 0 protostar HOPS 358 decreased in 350 GHz continuum brightness by $sim25$% over the course of four years before brightening again for the next […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhen Cao, F. Aharonian, Y. X. Bai, Y. W. Bao, D. Bastieri | Summary: In this study, we present a comprehensive analysis of an unidentified point-like ultra-high-energy (UHE) $gamma$-ray source, designated as 1LHAASO J1740+0948u, situated in the vicinity of the middle-aged pulsar PSR J1740+1000. The detection significance […]

Kavli Affiliate: Xian Chen | First 5 Authors: Mingfu Liang, Xi Liu, Rong Jin, Boyang Liu, Qiuling Suo | Summary: Ads recommendation is a prominent service of online advertising systems and has been actively studied. Recent studies indicate that scaling-up and advanced design of the recommendation model can bring significant performance improvement. However, with a […]
Siwei Zou, Robert A. Simcoe, Patrick Petitjean, Celine Peroux, Jaclyn B. Champagne | Summary: [[{“value”:”Cold and cool gas (T $leq 10^4$ K) in the circumgalactic medium (CGM) and its interaction with galaxies remain poorly understood. Simulations predict that cold gas flows into galaxies through cosmic filaments, determining the disk formation and galaxy evolution. The cold […]
