WTP19aalnxx: Discovery of a bright mid-infrared transient in the emerging class of low luminosity supernovae revealed by delayed circumstellar interaction

Posted by dbos MIT

Kavli Affiliate: Robert Simcoe | First 5 Authors: Charlotte Myers, Kishalay De, Lin Yan, Jacob E. Jencson, Nicholas Earley | Summary: While core-collapse supernovae (SNe) often show early and consistent signs of circumstellar (CSM) interaction, some exhibit delayed signatures due to interaction with distant material around the progenitor star. Here we present the discovery in […]

Test of light-lepton universality in $τ$ decays with the Belle II experiment

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Aihara | Summary: We present a measurement of the ratio $R_mu = mathcal{B}(tau^-to mu^-barnu_munu_tau) / mathcal{B}(tau^-to e^-barnu_enu_tau)$ of branching fractions $mathcal{B}$ of the $tau$ lepton decaying to muons or electrons using data collected with the Belle II […]

A Joint X-ray and Optical Study of the Massive Redback Pulsar J2215+5135

Posted by dbos Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Andrew G. Sullivan, Roger W. Romani, , , | Summary: PSR J2215+5135 (J2215) is a `redback’ spider pulsar, where the intrabinary shock (IBS) wraps around the pulsar rather than the stellar-mass companion. Spider orbital light curves are modulated, dominated by their binary companion thermal emission in […]

Entanglement-swapping in generalised probabilistic theories, and iterated CHSH games

Posted by dbos UCSB

Kavli Affiliate: David Gross | First 5 Authors: Lionel J. Dmello, Laurens T. Ligthart, David Gross, , | Summary: While there exist theories that have states "more strongly entangled" than quantum theory, in the sense that they show CHSH values above Tsirelson’s bound, all known examples of such theories have a strictly smaller set of […]

Rearrangement collision theory of phonon-driven exciton dissociation

Posted by dbos Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Christopher J. N. Coveney, Jonah B. Haber, Antonios M. Alvertis, Jeffrey B. Neaton, Marina R. Filip | Summary: Understanding the processes governing the dissociation of excitons to free charge carriers in semiconductors and insulators is of central importance for photovoltaic applications. Dyson’s $mathcal{S}$-matrix formalism provides a […]

Sensitivity and control of a 6-axis fused-silica seismometer

Posted by dbos MIT

Kavli Affiliate: Richard Mittleman | First 5 Authors: Jiri Smetana, Amit Singh Ubhi, Emilia Chick, Leonid Prokhorov, John Bryant | Summary: We present a pair of seismometers capable of measurement in all six axes of rigid motion. The vacuum-compatible devices implement compact interferometric displacement sensors to surpass the sensitivity of typical electrical readout schemes. Together […]
