MUSEQuBES: Physical conditions, origins, and multi-element abundances of the circumgalactic medium of an isolated, star-forming dwarf galaxy at z=0.57

Posted by klaurent Chicago

Kavli Affiliate: Hsiaowen Chen |Summary:In dwarf galaxy models, outflows expel metal-enriched interstellar medium (ISM) into the circumgalactic medium (CGM) to reproduce their observed low metallicities, but measurements of dwarf CGM properties are scarce. We present a study of the CGM of an isolated dwarf at $z=0.5723$ with a stellar mass of $approx5times10^7rm,M_odot$ and star-formation rate […]

Reducing systematic uncertainties in gravitational-wave population analyses by increasing the detection threshold

Posted by klaurent MIT

Kavli Affiliate: Salvatore Vitale | Summary:From catalogs of gravitational-wave transients, the population-level properties of their sources and the formation channels of merging compact binaries can be constrained. However, astrophysical conclusions can be biased by misspecification or misestimation of the population likelihood. Despite detection thresholds on the false-alarm rate (FAR) or signal-to-noise ratio (SNR), the current […]

Nonlinear Evolution of the Matter Trispectrum with Primordial Parity Violation

Posted by klaurent Tokyo

Kavli Affiliate: Eiichiro Komatsu | Summary:Parity-odd four-point correlation functions, or trispectra, of cosmic matter density fields provide a unique probe of fundamental symmetries in cosmology. Trispectra of primordial matter density fluctuations produced in the early universe are modified by the subsequent nonlinear structure formation. In this paper, we compute the nonlinear evolution of the parity-odd […]

Quantum Strategies to Overcome Classical Multiplexing Limits

Posted by klaurent Delft

Kavli Affiliate: Stephanie Wehner | Summary:Near-term quantum networks face a bottleneck due to low quantum communication rates. This degrades performance both by lowering operating speeds and increasing qubit storage time in noisy memories, making some quantum internet applications infeasible. One way to circumvent this bottleneck is multiplexing: combining multiple signals into a single signal to […]

Commensurate-incommensurate Mott transition without magnetic field: emergence of nematic Luttinger liquid in XXZ chain

Posted by klaurent Delft

Kavli Affiliate: Natalia Chepiga | Summary:We investigate the zero-magnetization phase diagram of a spin-1/2 chain with competing ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchange couplings in the strongly interacting regime. Using density matrix renormalization group (DMRG) simulations, we discover two successive commensurate-incommensurate transitions of the non-conformal Pokrovsky-Talapov universality class, occurring (even) at zero magnetic field. The […]

First Measurement of the $D_s^+rightarrow K^0μ^+ν_μ$ Decay

Posted by klaurent Cornell

Kavli Affiliate: Chris Xu| First 5 Authors: BESIII Collaboration, BESIII Collaboration, , , | Summary:We report the first measurement of the semileptonic decay $D^+_s rightarrow K^0μ^+ν_μ$, using a sample of $e^+e^-$ annihilation data corresponding to an integrated luminosity of $7.33~mathrmfb^-1$ collected at center-of-mass energies between 4.128 to 4.226~GeV with the BESIII detector at the BEPCII […]
