Detection of the CMB lensing — galaxy bispectrum

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Gerrit S. Farren, Blake D. Sherwin, Boris Bolliet, Toshiya Namikawa, Simone Ferraro | Summary: We present a first measurement of the galaxy-galaxy-CMB lensing bispectrum. The signal is detected at $26sigma$ and $22sigma$ significance using two samples from the unWISE galaxy catalog at mean redshifts $bar{z}=0.6$ and $1.1$ […]

Galaxy Spectra neural Network (GaSNet). II. Using Deep Learning for Spectral Classification and Redshift Predictions

Kavli Affiliate: Claudio Ricci | First 5 Authors: Fucheng Zhong, Nicola R. Napolitano, Caroline Heneka, Rui Li, Franz Erik Bauer | Summary: Large sky spectroscopic surveys have reached the scale of photometric surveys in terms of sample sizes and data complexity. These huge datasets require efficient, accurate, and flexible automated tools for data analysis and […]

The robustness in identifying and quantifying high-redshift bars using JWST observations

Kavli Affiliate: Luis C. Ho | First 5 Authors: Xinyue Liang, Si-Yue Yu, Taotao Fang, Luis C. Ho, | Summary: Understanding the methodological robustness in identifying and quantifying high-redshift bars is essential for studying their evolution with the {it James} {it Webb} Space Telescope (JWST). Using a sample of nearby spiral galaxies, we created simulated […]

X-ray Polarization Reveals the Precessions of the Neutron Star in Hercules X-1

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Jeremy Heyl, Victor Doroshenko, Denis González-Caniulef, Ilaria Caiazzo, Juri Poutanen | Summary: In an accreting X-ray pulsar, a neutron star accretes matter from a stellar companion through an accretion disk. The high magnetic field of the rotating neutron star disrupts the inner edge of the disc, […]

The impact of selection biases on tests of general relativity with gravitational-wave inspirals

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Ryan Magee, Maximiliano Isi, Ethan Payne, Katerina Chatziioannou, Will M. Farr | Summary: Tests of general relativity with gravitational wave observations from merging compact binaries continue to confirm Einstein’s theory of gravity with increasing precision. However, these tests have so far only been applied to signals that […]

The Effects of the Local Environment on a Compact Radio Interferometer I: Cross-coupling in the Tianlai Dish Pathfinder Array

Kavli Affiliate: Albert Stebbins | First 5 Authors: Juhun Kwak, John Podczerwinski, Peter Timbie, Réza Ansari, John Marriner | Summary: The visibilities measured by radio astronomical interferometers include non-astronomical correlated signals that arise from the local environment of the array. These correlated signals are especially important in compact arrays such as those under development for […]

Exploring Active Learning in Meta-Learning: Enhancing Context Set Labeling

Kavli Affiliate: Jing Wang | First 5 Authors: Wonho Bae, Jing Wang, Danica J. Sutherland, , | Summary: Most meta-learning methods assume that the (very small) context set used to establish a new task at test time is passively provided. In some settings, however, it is feasible to actively select which points to label; the […]

On Why the 10-TeV Cosmic Ray Bump Originates in the Local Interstellar Medium

Kavli Affiliate: Igor Moskalenko | First 5 Authors: Mikhail Malkov, Patrick Diamond, Mingyun Cao, Igor Moskalenko, | Summary: Recent measurements of primary and secondary CR spectra, their arrival directions, and our improved knowledge of the magnetic field geometry around the heliosphere allow us to set a bound on the distance beyond which a puzzling 10-TeV […]
