Sample Efficient Algorithms for Linear System Identification under Noisy Observations

Kavli Affiliate: Jia Liu | First 5 Authors: Yuyang Zhang, Xinhe Zhang, Jia Liu, Na Li, | Summary: In this paper, we focus on learning linear dynamical systems under noisy observations. In this setting, existing algorithms either yield biased parameter estimates, or suffer from large sample complexities. To address these issues, we adapt the instrumental […]

The Effect of Nonlinear Gravity on the Cosmological Background During Preheating

Kavli Affiliate: Joshua Frieman | First 5 Authors: Ryn Grutkoski, Hayley J. Macpherson, John T. Giblin Jr, Joshua Frieman, | Summary: We use numerical relativity to study the violent preheating era at the end of inflation. This epoch can result in highly nonlinear fluctuations in density and gravitational potential which feed back onto the averaged […]

Disk-jet coupling across the spectral transition in supermassive black holes

Kavli Affiliate: John D. Silverman | First 5 Authors: Jia-Lai Kang, Chris Done, Scott Hagen, Mai Liao, Matthew J. Temple | Summary: Accretion flows in both stellar and supermassive black holes show a distinct spectral transition. This is seen directly in binaries and changing look AGN, and also in a recent sample of eROSITA X-ray […]

ELVES-Dwarf I: Satellites Systems of Eight Isolated Dwarf Galaxies in the Local Volume

Jiaxuan Li, Jenny E. Greene, Shany Danieli, Scott G. Carlsten, Marla Geha | Summary: [[{“value”:”The satellite populations of Milky Way–mass systems have been extensively studied, significantly advancing our understanding of galaxy formation and dark matter physics. In contrast, the satellites of lower-mass dwarf galaxies remain largely unexplored, despite hierarchical structure formation predicting that dwarf galaxies […]
