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). We used nearby spiral galaxies to generate simulated images at […]

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 […]
