Short GRB Host Galaxies I: Photometric and Spectroscopic Catalogs, Host Associations, and Galactocentric Offsets
Wen-fai Fong, Anya E. Nugent, Yuxin Dong +25
We present a comprehensive optical and near-infrared census of the fields of 90 short gamma-ray bursts (GRBs) discovered in 2005-2021, constituting all short GRBs for which host ga…
The Co-evolution of Cosmic Entropy and Structures in the Universe
Xinghai Zhao, Yuexing Li, Qirong Zhu +1
According to the second law of thermodynamics, the arrow of time points to an ever increasing entropy of the Universe. However, exactly how the entropy evolves with time and what d…
Observational strategies for ultrahigh-energy neutrinos: the importance of deep sensitivity for detection and astronomy
Kumiko Kotera, Mainak Mukhopadhyay, Rafael Alves Batista +5
Detecting ultrahigh-energy neutrinos can take two complementary approaches with different trade-offs. 1)~Wide and shallow: aim for the largest effective volume, and to be cost-effe…
Calibrating the cosmic distance ladder using gravitational-wave observations
Anuradha Gupta, Derek Fox, B. S. Sathyaprakash +1
Type Ia supernovae (SNe Ia) are among preeminent distance ladders for precision cosmology due to their intrinsic brightness, which allows them to be observable at high redshifts. T…
Stochastic Variance-Reduced Iterative Hard Thresholding in Graph Sparsity Optimization
Derek Fox, Samuel Hernandez, Qianqian Tong
Stochastic optimization algorithms are widely used for large-scale data analysis due to their low per-iteration costs, but they often suffer from slow asymptotic convergence caused…
Astro2010 Decadal Survey Whitepaper: Coordinated Science in the Gravitational and Electromagnetic Skies
Joshua S. Bloom, Daniel E. Holz, Scott A. Hughes +37
It is widely expected that the coming decade will witness the first direct detection of gravitational waves (GWs). The ground-based LIGO and Virgo GW observatories are being upgrad…
