Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Zhilei Xu, Jacqueline N. Hewitt, Kai-Feng Chen, Honggeun Kim, Joshua S. Dillon | Summary: Motivated by the desire for wide-field images with well-defined statistical properties for 21cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator for the sky using the interferometric […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Zarif Kader, Calvin Leung, Matt Dobbs, Kiyoshi W. Masui, Daniele Michilli | Summary: The gravitational field of compact objects, such as primordial black holes, can create multiple images of background sources. For transients such as fast radio bursts (FRBs), these multiple images can be resolved in […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Halston Lim, Gaurav Khanna, Scott A. Hughes, , | Summary: In recent work, we examined how different modes in the ringdown phase of a binary coalescence are excited as a function of the final plunge geometry. At least in the large mass ratio limit, we found […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Adriana Errico, Robert A. Wittenmyer, Jonathan Horner, Zhexing Li, Gregory Mirek Brandt | Summary: We report the discovery of a highly eccentric long-period Jovian planet orbiting the hot-Jupiter host HD,83443. By combining radial velocity data from four instruments (AAT/UCLES, Keck/HIRES, HARPS, Minerva-Australis) spanning more than two decades, […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Pierre Auclair, David Bacon, Tessa Baker, Tiago Barreiro, Nicola Bartolo | Summary: The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I explore the properties of "dark gaps" – regions in quasar absorption spectra without significant transmission – with several simulations from the Cosmic Reionization On Computers (CROC) project. CROC simulations in largest available boxes (120 cMpc) come close […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: We discuss the action of a subgroup on small nilpotent orbits, and prove a bounded multiplicity property for the restriction of minimal representations of real reductive Lie groups with respect to arbitrary reductive symmetric pairs. | Search Query: ArXiv Query: […]
