The origin of the unfocused XMM-Newton background, its variability and lessons learned for ATHENA

Kavli Affiliate: Catherine E. Grant | First 5 Authors: Fabio Gastaldello, Martino Marelli, Silvano Molendi, Iacopo Bartalucci, Patrick Kühl | Summary: We analyzed the unexposed to the sky outFOV region of the MOS2 detector on board XMM-Newton covering 15 years of data amounting to 255 Ms. We show convincing evidence that the origin of the […]

The impact of galaxy selection on the splashback boundaries of galaxy clusters

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stephanie O’Neil, Josh Borrow, Mark Vogelsberger, Benedikt Diemer, | Summary: We explore how the splashback radius ($R_{rm sp}$) of galaxy clusters, measured using the number density of the subhalo population, changes based on various selection criteria using the IllustrisTNG cosmological galaxy formation simulation. We identify $R_{rm sp}$ […]

Extracting high-order cosmological information in galaxy surveys with power spectra

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Yuting Wang, Gong-Bo Zhao, Kazuya Koyama, Will J. Percival, Ryuichi Takahashi | Summary: The reconstruction method was proposed more than a decade ago to boost the signal of baryonic acoustic oscillations measured in galaxy redshift surveys, which is one of key probes for dark energy. After moving […]

Extracting high-order cosmological information in galaxy surveys with power spectra

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Yuting Wang, Gong-Bo Zhao, Kazuya Koyama, Will J. Percival, Ryuichi Takahashi | Summary: The “reconstruction" method was proposed more than a decade ago to boost the signal of baryonic acoustic oscillations measured in galaxy redshift surveys, which is one of key probes for dark energy. After moving […]

Constructing graphs having Laplacian pair state transfer by an edge perturbation

Kavli Affiliate: Jing Wang | First 5 Authors: Wei Wang, Xiaogang Liu, Jing Wang, , | Summary: In this paper, we give some sufficient conditions for graphs with an edge perturbation between twin vertices to have Laplacian perfect pair state transfer as well as Laplacian pretty good pair state transfer. By those sufficient conditions, we […]

InferGrad: Improving Diffusion Models for Vocoder by Considering Inference in Training

Kavli Affiliate: Ke Wang | First 5 Authors: Zehua Chen, Xu Tan, Ke Wang, Shifeng Pan, Danilo Mandic | Summary: Denoising diffusion probabilistic models (diffusion models for short) require a large number of iterations in inference to achieve the generation quality that matches or surpasses the state-of-the-art generative models, which invariably results in slow inference […]

Predicting the Exoplanet Yield of the TESS Prime and Extended Missions Through Years 1-7

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Michelle Kunimoto, Joshua N. Winn, George R. Ricker, Roland Vanderspek, | Summary: The Transiting Exoplanet Survey Satellite (TESS) has discovered $sim$5000 planets and planet candidates after three and a half years of observations. With a planned second Extended Mission spanning Years 5 – 7 on the horizon, […]
