FAST discovery of an extremely radio-faint millisecond pulsar from the Fermi-LAT unassociated source 3FGL J0318.1+0252

Kavli Affiliate: Peter F. Michelson | First 5 Authors: Pei Wang, Di Li, Colin J. Clark, Pablo Saz Parkinson, Xian Hou | Summary: High sensitivity radio searches of unassociated $gamma$-ray sources have proven to be an effective way of finding new pulsars. Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) during its commissioning phase, we […]

Confluence in quantum K-theory of weak Fano manifolds and q-oscillatory integrals for toric manifolds

Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, Alexis Roquefeuil, , , | Summary: For a smooth projective variety whose anti-canonical bundle is nef, we prove confluence of the small $K$-theoretic $J$-function, i.e., after rescaling appropriately the Novikov variables, the small $K$-theoretic $J$-function has a limit when $qto 1$, which coincides with the […]

Detection of H$_2$ in the TWA 7 System: A Probable Circumstellar Origin

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Laura Flagg, Christopher Johns-Krull, Kevin France, Gregory Herczeg, Joan Najita | Summary: Using HST-COS FUV spectra, we have discovered warm molecular hydrogen in the TWA 7 system. TWA 7, a $sim$9 Myr old M2.5 star, has a cold debris disk and has previously shown no signs of […]

Tuning color centers at a twisted interface

Kavli Affiliate: Michael Crommie | First 5 Authors: Cong Su, Fang Zhang, Salman Kahn, Brian Shevitski, Jingwei Jiang | Summary: Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Employing cathodoluminescence, we demonstrate that an ultraviolet-emitting single photon emitter can […]
