Multi-messenger astrophysics in the gravitational-wave era

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Geoffrey Mo, Rahul Jayaraman, Danielle Frostig, Michael M. Fausnaugh, Erik Katsavounidis | Summary: The observation of GW170817, the first binary neutron star merger observed in both gravitational waves (GW) and electromagnetic (EM) waves, kickstarted the age of multi-messenger GW astronomy. This new technique presents an observationally […]

JADES: Carbon enrichment 350 Myr after the Big Bang in a gas-rich galaxy

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Stefano Carniani, Emma Curtis-Lake, Joris Witstok | Summary: Finding the emergence of the first generation of metals in the early Universe, and identifying their origin, are some of the most important goals of modern astrophysics. We present deep JWST/NIRSpec spectroscopy of GS-z12, a […]

GRB 180128A: A Second Magnetar Giant Flare Candidate from the Sculptor Galaxy

Kavli Affiliate: Nicola Omodei | First 5 Authors: Aaron C. Trigg, Eric Burns, Oliver J. Roberts, Michela Negro, Dmitry S. Svinkin | Summary: Magnetars are slowly rotating neutron stars that possess the strongest magnetic fields ($10^{14}-10^{15} mathrm{G}$) known in the cosmos. They display a range of transient high-energy electromagnetic activity. The brightest and most energetic […]

Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals

Kavli Affiliate: Joshua Frieman | First 5 Authors: Chin Yi Tan, Anowar J. Shajib, Simon Birrer, Alessandro Sonnenfeld, Tommaso Treu | Summary: The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The power-law assumption for the radial mass profile in ellipticals […]

BPS Fivebrane Stars II: Fluctuations

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We investigate quantum fluctuations of metric components in coherent 1/2-BPS bound states of $n_1$ fundamental strings and $n_5$ NS5-branes. The leading order contribution in an expansion in $1/(n_1n_5)$ is calculated via a combination of analytical and numerical […]

BPS Fivebrane Stars I: Expectation Values of Observables

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We study ensembles of 1/2-BPS bound states of fundamental strings and NS-fivebranes (NS5-F1 states) in the AdS decoupling limit. We revisit a solution corresponding to an ensemble average of these bound states, and find that the appropriate […]

Josephson Diode Effect in Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect in topological Josephson junctions. We find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the trivial phase, this behavior is not universal. […]
