The missing link in gravitational-wave astronomy: A summary of discoveries waiting in the decihertz range

Posted by klaurent Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Manuel Arca Sedda, Christopher P L Berry, Karan Jani, Pau Amaro-Seoane, Pierre Auclair | Summary: Since 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wave observatories such as LIGO, Virgo, and their successors will […]

MarioNette: Self-Supervised Sprite Learning

Posted by klaurent UCSB

Kavli Affiliate: Matthew Fisher | First 5 Authors: Dmitriy Smirnov, Michael Gharbi, Matthew Fisher, Vitor Guizilini, Alexei A. Efros | Summary: Artists and video game designers often construct 2D animations using libraries of sprites — textured patches of objects and characters. We propose a deep learning approach that decomposes sprite-based video animations into a disentangled […]

Beyond spectroscopy. I. Metallicities, distances, and age estimates for over twenty million stars from SMSS DR2 and Gaia EDR3

Posted by klaurent Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Yang Huang, Timothy C. Beers, Christian Wolf, Young Sun Lee, Christopher A. Onken | Summary: Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galaxy. Here we present stellar atmospheric […]

Hubble Space Telescope UV and H$α$ Measurements of the Accretion Excess Emission from the Young Giant Planet PDS 70 b

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Yifan Zhou, Brendan P. Bowler, Kevin R. Wagner, Glenn Schneider, Dániel Apai | Summary: Recent discoveries of young exoplanets within their natal disks offer exciting opportunities to study ongoing planet formation. In particular, a planet’s mass accretion rate can be constrained by observing the accretion-induced excess […]

Signatures of Recent Cosmic-Ray Acceleration in the High-Latitude $γ$-Ray Sky

Posted by klaurent Stanford

Kavli Affiliate: Troy A. Porter | First 5 Authors: Guðlaugur Jóhannesson, Troy A. Porter, , , | Summary: Cosmic-ray (CR) sources temporarily enhance the relativistic particle density in their vicinity over the background distribution accumulated from the Galaxy-wide past injection activity and propagation. If individual sources are close enough to the solar system, their localised […]

Cosmological Evolution of the Formation Rate of Short Gamma-ray Bursts With and Without Extended Emission

Posted by klaurent Stanford

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Vahe’ Petrosian, Luke Bowden, , | Summary: Originating from neutron star-neutron star (NS-NS) or neutron star-black hole (NS-BH) mergers, short gamma-ray bursts (SGRBs) are the first electromagnetic emitters associated with gravitational waves. This association makes the determination of SGRB formation rate (FR) a critical […]

Quasicrystal kirigami

Posted by klaurent Harvard

Kavli Affiliate: L. Mahadevan | First 5 Authors: Lucy Liu, Gary P. T. Choi, L. Mahadevan, , | Summary: Kirigami, the art of introducing cuts in thin sheets to enable articulation and deployment, has become an inspiration for a novel class of mechanical metamaterials with unusual properties. Here we complement the use of periodic tiling […]
