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 […]

Spatiotemporal Crossover between Low- and High-Temperature Dynamical Regimes in the Quantum Heisenberg Magnet

Posted by Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Nicholas E. Sherman, Joel E. Moore, , | Summary: The stranglehold of low temperatures on fascinating quantum phenomena in one-dimensional quantum magnets has been challenged recently by the discovery of anomalous spin transport at high temperatures. Whereas both regimes have been investigated separately, no […]

Distant Relatives: The Chemical Homogeneity of Comoving Pairs Identified in Gaia

Posted by klaurent Chicago

Kavli Affiliate: Alexander Ji | First 5 Authors: Tyler Nelson, Yuan-Sen Ting, Keith Hawkins, Alexander Ji, Harshil Kamdar | Summary: Comoving pairs, even at the separations of $mathcal{O}(10^6),$AU, are a predicted reservoir of conatal stars. We present detailed chemical abundances of 62 stars in 31 comoving pairs with separations of $10^2 – 10^7,$AU and 3D […]

From haloes to galaxies. III. The gas cycle of local galaxy populations

Posted by klaurent Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci | Summary: In Dou et al. (2021), we introduced the Fundamental Formation Relation (FFR), a tight relation between specific SFR (sSFR), H$_2$ star formation efficiency (SFE$_{rm H_2}$), and the ratio of H$_2$ to stellar mass. Here […]
