Realistic Detection and Early Warning of Binary Neutron Stars with Decihertz Gravitational-wave Observatories

Kavli Affiliate: Lijing Shao | First 5 Authors: Chang Liu, Yacheng Kang, Lijing Shao, , | Summary: We investigated the detection and localization of binary neutron star (BNS) populations with decihertz gravitational-wave observatories in a realistic detecting strategy, including real-time observations and early warnings. Assuming 4 years’ operation of B-DECIGO, we found that the detected […]

Dark radiation as a probe for phase transition in the early universe

Kavli Affiliate: Lijing Shao | First 5 Authors: Zihang Wang, Lijing Shao, , , | Summary: The cosmological constant is not necessarily small in the early universe. If a scalar field obtains a vacuum expectation value after a phase transition (PT), a possibly large cosmological constant could present before PT. The early cosmological constant (ECC) […]

Free-Floating Planets, the Einstein Desert, and ‘Oumuamua

Kavli Affiliate: Subo Dong | First 5 Authors: Andrew Gould, Youn Kil Jung, Kyu-Ha Hwang, Subo Dong, Michael D. Albrow | Summary: We complete the survey for finite-source/point-lens (FSPL) giant-source events in 2016-2019 KMTNet microlensing data. The 30 FSPL events show a clear gap in Einstein radius, $9,mu{rm as}<theta_{rm E} <26,mu{rm as}$, which is consistent […]

Unsupervised Learning of Accurate Siamese Tracking

Kavli Affiliate: Li Xin Li | First 5 Authors: Qiuhong Shen, Lei Qiao, Jinyang Guo, Peixia Li, Xin Li | Summary: Unsupervised learning has been popular in various computer vision tasks, including visual object tracking. However, prior unsupervised tracking approaches rely heavily on spatial supervision from template-search pairs and are still unable to track objects […]

Spatially resolved molecular interstellar medium in a $z=6.6$ quasar host galaxy

Kavli Affiliate: Ran Wang | First 5 Authors: Jianan Li, Bram P. Venemans, Fabian Walter, Roberto Decarli, Ran Wang | Summary: We present high spatial resolution (0.4", 2.2kpc) observations of the CO(6-5), CO(7-6) and [CI] lines and dust continuum emission from the interstellar medium in the host galaxy of the quasar J0305$-$3150 at $z=6.6$. These, […]
