Geometric deformation and redshift structure caused by plane gravitational waves

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Chao-Jun Feng, , , | Summary: The curved spacetime induced by gravitational waves can give rise to visual effects such as geometric distortions and redshift structures in the observed image. By establishing a mapping from the object’s surface coordinates to the observer’s screen coordinates, we […]

Monitoring AGNs with H$β$ Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs

Kavli Affiliate: Luis C. Ho | First 5 Authors: T. E. Zastrocky, Michael S. Brotherton, Pu Du, Jacob N. McLane, Kianna A. Olson | Summary: We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H$beta$ Asymmetry campaign (MAHA). These results utilize optical spectra obtained with the Long Slit Spectrograph […]

Searching for Cosmological Collider in the Planck CMB Data

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Wuhyun Sohn, Dong-Gang Wang, James R. Fergusson, E. P. S. Shellard, | Summary: In this paper, we present the first comprehensive CMB data analysis of cosmological collider physics. New heavy particles during inflation can leave imprints in the primordial correlators which are observable in today’s […]

Extracting Clean and Balanced Subset for Noisy Long-tailed Classification

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, He Zhao, Zhen Li, Tongliang Liu, Dandan Guo | Summary: Real-world datasets usually are class-imbalanced and corrupted by label noise. To solve the joint issue of long-tailed distribution and label noise, most previous works usually aim to design a noise detector to distinguish the noisy […]

Mediator Decay through mixing with Degenerate Spectrum

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Ayuki Kamada, Takumi Kuwahara, Shigeki Matsumoto, Yu Watanabe, Yuki Watanabe | Summary: The decay of the mediator particle into standard model (SM) particles plays a significant role in exploring the dark sector scenario. We consider such a decay, taking the dark photon mediator as an example that […]

Analyzing the Atmospheric Dispersion Correction of the Gemini Planet Imager: residual dispersion above design requirements

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Malachi Noel, Jason J. Wang, Bruce Macintosh, Katie Crotts, Christian Marois | Summary: The Atmospheric Dispersion Corrector (ADC) of the Gemini Planet Imager (GPI) corrects the chromatic dispersion caused by differential atmospheric refraction (DAR), making it an important optic for exoplanet observation. Despite requiring less than 5 […]
