Gravitational wave backgrounds from coalescing black hole binaries at cosmic dawn: an upper bound

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Kazumi Kashiyama, Eli Visbal, Zoltan Haiman, | Summary: The successive discoveries of binary merger events by Advanced LIGO-Virgo have been revealing the statistical properties of binary black hole (BBH) populations. A stochastic gravitational wave background (GWB) is a useful tool to probe the cosmological evolution […]

On the Mass Loading of AGN-Driven Outflows in Elliptical Galaxies and Clusters

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yu Qiu, Brian R. McNamara, Tamara Bogdanovic, Kohei Inayoshi, Luis C. Ho | Summary: Outflows driven by active galactic nuclei (AGN) are an important channel for accreting supermassive black holes (SMBHs) to interact with their host galaxies and clusters. Properties of the outflows are however poorly constrained […]

A Higher Probability of Detecting Lensed Supermassive Black Hole Binaries by LISA

Kavli Affiliate: Xian Chen | First 5 Authors: Zucheng Gao, Xian Chen, Yi-Ming Hu, Jian-Dong Zhang, Shunjia Huang | Summary: Gravitational lensing of gravitational waves (GWs) is a powerful probe of the matter distribution in the universe. Here we revisit the wave-optics effects induced by dark matter (DM) halos on the GW signals of merging […]

Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)

Kavli Affiliate: Subo Dong | First 5 Authors: S. J. Brennan, M. Fraser, J. Johansson, A. Pastorello, R. Kotak | Summary: We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current literature by adding higher cadence as well as extended coverage […]

Rethinking the Optimization of Average Precision: Only Penalizing Negative Instances before Positive Ones is Enough

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Weiqing Min, Jiajun Song, Yaohui Zhu, Liping Kang | Summary: Optimising the approximation of Average Precision (AP) has been widely studied for image retrieval. Limited by the definition of AP, such methods consider both negative and positive instances ranking before each positive instance. However, we […]

WheaCha: A Method for Explaining the Predictions of Models of Code

Kavli Affiliate: Ke Wang | First 5 Authors: Yu Wang, Ke Wang, Linzhang Wang, , | Summary: Attribution methods have emerged as a popular approach to interpreting model predictions based on the relevance of input features. Although the feature importance ranking can provide insights of how models arrive at a prediction from a raw input, […]

How does the Polar Dust affect the Correlation between Dust Covering Factor and Eddington Ratio in Type 1 Quasars Selected from the Sloan Digital Sky Survey Data Release 16?

Kavli Affiliate: Claudio Ricci | First 5 Authors: Yoshiki Toba, Yoshihiro Ueda, Poshak Gandhi, Claudio Ricci, Denis Burgarella | Summary: We revisit the dependence of covering factor (CF) of dust torus on physical properties of active galactic nuclei (AGNs) by taking into account an AGN polar dust emission. The CF is converted from a ratio […]

BAT AGN Spectroscopic Survey-XXIII. A New Mid-Infrared Diagnostic for Absorption in Active Galactic Nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Ryan W. Pfeifle, Claudio Ricci, Peter G. Boorman, Marko Stalevski, Daniel Asmus | Summary: In this study, we use the SWIFT/BAT AGN sample, which has received extensive multiwavelength follow-up analysis as a result of the BAT AGN Spectroscopic Survey (BASS), to develop a diagnostic for nuclear obscuration […]

Eclipsing Binary Populations across the Northern Galactic Plane from the KISOGP survey

Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangzhou Ren, Richard de Grijs, Huawei Zhang, Licai Deng, Xiaodian Chen | Summary: We present a catalog of eclipsing binaries in the northern Galactic Plane from the Kiso Wide-Field Camera Intensive Survey of the Galactic Plane (KISOGP). We visually identified 7055 eclipsing binaries spread across $sim$330 square […]

“A more probable explanation” is still impossible to explain GN-z11-flash: in response to Steinhardt et al. (arXiv:2101.12738)

Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shu Wang, Bing Zhang, Nobunari Kashikawa, Luis C. Ho | Summary: In Jiang et al. (2020), we reported a possible bright flash (hereafter GN-z11-flash) from a galaxy GN-z11 at z ~ 11. Recently, Steinhardt et al. (2021; arXiv:2101.12738) found 27 images with transient signals in […]
